Harsco Metals Polska is the only company in Poland that provides steel mills with a full, comprehensive and round-the-clock service related to slag, starting from the evacuation of liquid slag from the steelworks, through its cooling, transport and processing, up to the delivery of the produced batch scrap . We currently use 6 high-performance slag processing lines in Poland , the design of which is the result of over 50 years of experience of our specialists in steel plants in the USA. In the production of steel, steel slag is produced as production wastewhich settles on the surface of the furnace. The molten slag is poured into a slag chamber, from where it is collected by wheel loaders and taken outside the steel plant for cooling. The last stage before starting the processing of waste is delivering the cooled slag to the place of its processing, i.e. to the production line. Specialized equipment and properly trained people are used to collect and transport liquid slag from ongoing production. Here too, half a century of experience in the slag industry helps to ensure safe and efficient operations. In order to provide round-the-clock metallurgical services, it is necessary to use appropriate chargers and technological dumpers. At the same time, we use the right type of machines to transport slag from used heaps, i.e. old metallurgical storage yards, to the production line. All of these devices are financed by Harsco Metals Polska. The slag processing line consists of a series of conveyors, magnetic separators and double-deck vibrating screens . After the steel slag is delivered to the line, the process of separating magnetic materials (scrap) and non-magnetic materials (aggregate) takes place. The waste processed by the production line must not exceed 300 mm in length, so the slag and large-size scrap are initially broken into smaller ones using a pile driver. The magnetic material is sorted into appropriate scrap grades according to its size and percentage of iron, and then placed on a suitable conveyor belt and stored in the form of small piles. As a result of the use of magnetic separation, we obtain steel coarse and pig iron scrap free of foreign impurities, which is a valuable input material for metallurgy. A similar procedure is applied to non-magnetic material, i.e. aggregate , sorted in terms of size into several fractions. The product obtained in this way, in the case of slag from current production, must still be stored in a landfill for a minimum of 6 months to be safely used in road construction. On the other hand, the aggregate produced from the slag from the heap can be used directly. As a result, we get a clean material with an appropriate grain fraction, applicable in the construction of roads of all categories, embankments, and in general construction .
