Integrated steel works
Steel is one of the most important materials for almost all
sectors in civil engineering, in machine and tool building andthrough to precision engineering. Due to the harsh process
conditions and the enormous demand for raw materials
and energy, the optimisation of production processes isgiven high priority. The product quality and reproducibility ofbatches are of the utmost importance as they reduce the costof the process. Iron and steel production processes requirerobust measurement technology that is capable of detecting
faults reliably while keeping the cost-effectiveness of theprocess in view.
When it comes to the right solutions for your production processes, you can rely on WIKA measurement
technology.

Sinter plant

Productivity and efficiency
With sintering, a mixture of fine ores, coke, recycled processmaterials and other aggregates is prepared, through melting,for further use in the blast furnace to ensure gas permeability
for the reducing gases.
For the sintering process, the control of the sintering hoodand its associated burner and the temperature in the furnace

are crucial. A lost oven can result in complete process stopand fluctuating temperatures affect the quality of the productbeing produced.
WIKA has a portfolio of high-performance measuring
instruments that are tailored to the measuring tasks of sinterplants.

Cost effectiveness and quality
In the coke plant, the coal is converted to coke by heating
the prepared coal mixture batch, in the absence of air, toa temperature of 1,000 to 1,300 °C for a period of 16 to
30 hours.
Coke, as a reducing agent, has a major impact on the
cost-effectiveness of the process and the quality of the final
product.
Challenge: The quality of the coke is determined by the
mixture of different types of coal.

In order to achieve optimal process conditions in coke plants,
the furnace pressure and the furnace temperature in theindividual furnaces are monitored individually.
In the coke plant, high-precision load cells ensure a controlled mixture of the various types of coal to achieve thedesired recipe composition. Our measuring instruments,
which are tailored precisely to the respective requirements,
guarantee a smooth processing of the vast quantities of raw
materials.

Pellet plant

Productivity and efficiency
Pellets are small balls of iron ore that are used in the production of steel. They are made with technology that utilises
the powder that is produced during ore extraction. The
process of granulation combines the blending of the raw
material and a thermal treatment that burns the soft greenpellets into hard balls. The raw material is rolled into a balland then fired in a furnace or in a travelling grate to sinter theparticles into a hard ball.

WIKA offers durable and high-quality process instrumentation for the production of the highest-quality pellets.

Blast furnace

High reliability for high availability
During the blast furnace process, sinter or pellets, inaddition to ore, coke and lime, serve to bind the unwanted
constituents of the ore in the slag and also reduce themelting temperature of the iron. They are fed from above into
the blast furnace, while hot compressed air is introduced
from the tuyères in the lower part. Auxiliary reducing agentsor fuels – such as coal, fuel oil, natural gas or other sources –can also be injected from the bottom of the furnace.

The monitoring of fuel pressure and temperature, as wellas the monitoring of blast furnace gas pressure are ofutmost importance to provide normalised consumption andoperating data for the process controls.
Efficient temperature monitoring enables the early detectionof possible system failures. WIKA thermocouples have
proven themselves to have fast and reliable temperaturedetection. Another challenge in blast furnace operation is themonitoring of cooling media.

Direct reduced iron plant
Process safety

Direct reduced iron (DRI), an alternative way of producing
iron, has been developed to overcome the difficulties of
conventional blast furnaces. DRI is successfully implemented
in various parts of the world using natural gas or coaltechnology. On the one hand, the DRI process is very
energy-efficient; on the other hand, further energy gains canbe realised if the hot material is immediately transferred to an
EAF melting operation (EAF = electric arc furnace).

In this way, the heat from the direct reduced iron process
reduces the cost of melting the DRI in the EAF, significantly
reducing energy costs.
Hydrogen represents a special challenge of the DRI process.
WIKA offers special pressure and temperature sensors forhydrogen applications to ensure the smooth running of the
DRI process.

Electric arc furnace
Energy and raw material efficiency
Scrap-based steels are recovered in the electric arc furnace.
After loading the furnace, the melting process begins with theignition of the arc. Using lances and/or burner systems andinjectors in the furnace wall, the introduction of the oxygen
and the fuel/gas mixtures takes place in order to accelerate
the melting and reduce the electrical energy requirement.

Through monitoring of fuel pressure, temperature and flow
values, normalised consumption and operating data areprovided for the process controls. WIKA flow measuring
instruments and pressure and temperature sensors perform
this control task reliably and accurately.

Ladle furnace

Improving the purity grade
Ladle furnaces in steel works are used in secondary
metallurgy for the treatment of liquid steel. The melt is further
desulphurised and adjusted to produce the steel grade
desired by the customer.
The cover of the ladle furnace is usually lined with refractorymaterials and water-cooled. To ensure optimum operation of
the ladle furnace, the exhaust duct, the electrode arms andthe cabling are also cooled. For this, sufficient water pressure
and the correct water inlet temperature are crucial.
Thanks to their robust measuring technology, our resistancethermometers and pressure sensors are ideal for monitoringcooling water. Pressure sensors can be installed quickly andeasily due to their compact dimensions.

Continuous casting plant
For the highest demands

In the continuous casting process, the liquid steel flows fromthe ladle through the distributor into the moulds. The steelfilled ladle is suspended in a rotatable tower that can hold twoladles. In the casting operation, both thermal and pressure
monitoring methods are used to detect local escape of liquid
steel or for penetration detection.
In order to prevent the penetration, it is essential to detect
the temperature profile in the casting mould so that thedevelopment of cracks can be determined. For this purpose,
thermocouples are embedded in the narrow and broadsides of the mould so that they show a two-dimensionaltemperature profile of all sides of the mould. To determine theheat dissipation in the mould, the cooling water temperature
at the cooling water inlet and outlet and also the coolant
quantity are measured.
WIKA takes into account the harsh operating conditions ofsteel foundries with extremely robust products. They featurehigh resistance against shock, vibration and temperaturefluctuations, high IP ingress protection and also outstanding
EMC characteristics.

Certified safety
Quality assurance
In steel production, extensive quality standards are
stringently specified. WIKA ensures this through an effective
quality assurance system.

Safety integrity level
The safety integrity level (SIL) of a component is certified
through a manufacturer's declaration on the basis of an
FMEDA (failure modes, effects and diagnostic analysis).
The FMEDA is a systematic evaluation of the random failure

behaviour of the component. With this, the statistical valuesof individual components and their functional correlations
are jointly assessed. The results are quantified data on theprobability of failure and the reliability of the components.

International approvals/certificates
High-quality components are essential for safe and reliable
production processes. They are a precondition for highly
efficient processes, helping to avoid danger to people, environment and property. Rigorous testing of the instruments

24

used, by national and international authorised bodies, results
in reliability and stable workflows. WIKA instruments offer awide range of approvals and certificates, worldwide.

Internet of Things

Wireless sensors are no longer simply suppliers of measured
values. Rather, the sensors can, in addition, be combinedwith extensive intelligence, so their performance is multiplied.

Autonomous wireless platform

Temperature sensors with SAW technology for low-voltage
and medium-voltage switchgear
The robust, wireless, fully passive sensors operate maintenance-free in high electromagnetic fields and in high current
and voltage environemnts (e.g. 20 kA, 545 kV). This enables
direct measurement on the inside of this critical industrial
equipment.
The unique temperature sensor has been designed for
critical applications in power plants. SAW temperature
sensors can be connected directly to the conductors, nobattery or power source is required. They feature easy
installation and maintenance. For new plants, they are alsoavailable as a retrofit solution.

27Engineered solutions
Miniature multipoint thermometers
In principle, miniature multipoints are made from individual measuring probes withlow diameters, which measure the temperature at different positions or heights.
Each individual probe is protected with a sheath from either stainless steel ora special alloy. The individual thermocouples can be combined within a single
thermowell. This design is used where the generation of a temperature profile
is required, but the weight or size of the multipoint is limited. These designs areavailable in a number of variants.

Temperature measurement in pilot plants
For research and development, processes are often built in pilot plants. Since
the measurement of temperature data for the understanding of a new or modified
process is of utmost importance, the thermocouple must be designed and manufactured carefully. Since the operation of pilot plants is on a smaller scale, thesensors must be scaled down, so as not to influence the processes taking place.
At the same time it is important that the measured temperatures are correct. These
factors are of utmost relevance and must already be taken into account during
design.

Replacement service

for diaphragm seal systems with process transmitters
With the replacement service, the total costs of the diaphragm seal system canbe clearly lowered. In this way, the service life of the process transmitter can be
fully utilised, because only the diaphragm seal is replaced, preventatively or after
failure.

In the event of a diaphragm rupture, a second diaphragm inthe diaphragm seal system ensures the reliable separationof the environment and the process. The measuring task
can still be performed. Time to act – without any risk for theprocess.

Extensive information can be foundin the flyer “Diaphragm monitoring”
at www.wika.com.

Diaphragm monitoring fordiaphragm seals

Variability
The diaphragm monitoring can be realised on a number of
instrument variants. You can choose between the following
basic models: Double-diaphragm system with flange connection and all

welded, flush diaphragm Double-diaphragm system with threaded connection andinternal, all welded diaphragm

Functional description
Diaphragm rupture detection: As soon as the monitoring
instrument detects any change in pressure, the diaphragmmonitoring system must be replaced.
Process pressure: Should a diaphragm rupture occur, the fullprocess pressure acts on the monitoring instrument. In theevent of a diaphragm rupture, the monitoring instrument must
therefore be designed for this process pressure.
Medium: In the event of a diaphragm rupture, the measuringsystem of the monitoring instrument comes into contact
with the medium. The measuring system must therefore besuitable for this medium.
Temperatures: The same process conditions apply tothe monitoring instrument as to the pressure measuring
instrument.

29

Diaphragm seals
Diaphragm seals are always used when the conditions at the
point of usage deviate from the permissible specifications forthe pressure measuring instrument. These are, for example:
 Too low or too high temperatures of the media
 Aggressive media
 Particle-laden media (also where there is scale formation

Diaphragm seals are delivered by WIKA as ready-to-use,
filled systems. These consist of the diaphragm seal itself (theprocess connection), the mounting element and the pressure
measuring instrument. All components are perfectly matchedto one another.

 Abrasive media
 Highly viscous media

The combined systems can withstand a pressure of 10 mbar
up to 3,600 bar at extreme temperatures (-130 … +400 °C)
and with a wide variety of media, thus enabling accuratepressure measurements under extreme conditions.

A further application is the connection of the measuring pointwith a remotely mounted pressure measuring instrument.

Materials
For high-pressure measurement, high-strength stainlesssteel is used, while for pressure measurements at elevated temperatures, temperature-resistant stainless steel isneeded. For processes involving highly aggressive media – in
combination with diaphragm seals/gauges with diaphragmfor pressure measurement, or thermowells for temperature
measurement – an extensive range of chemically resistantmaterials is available. In this case, all wetted parts are madeof this special material.
Diaphragm seals are manufactured from 316L stainlesssteel (1.4404/1.4435) as a standard. If diaphragm seals
are required with wetted parts in special metals, then theseare „metallically bonded“ using one of WIKA’s patented
procedures. The junction between the diaphragm and thediaphragm seal body is designed to be diffusion-tight,
vacuum protected and tear-resistant, and also resistant to all
extremes of temperature to which the diaphragm seal might
be exposed.
With pressure and differential pressure measuring
instruments using diaphragm elements, wetted parts canbe manufactured in the widest range of special materials.
Measuring systems for Bourdon tube instruments are
manufactured in 316L stainless steel (1.4404) as standard.
All pressure-bearing materials used can be supplied with a
3.1 traceability certificate.
