Electric Blast Furnace (GregTech 5)/en

The Electric Blast Furnace, or EBF, is a machine added by . It is an industrial upgrade of the conventional Furnace. It is a 3x3x4 multiblock construct, powered by (EU), and allows for the smelting of more advanced materials than the Furnace.
==Construction==
The Electric Blast Furnace is a 4-block high hollow 3x3 box. 
The top layer is constructed from 8 s around one . The Muffler Hatch must be facing upwards while facing an air block.
The two hollow middle layers are constructed from 16 .
The bottom layer is more mixed, and must contain the following:
* 1 , placed in the middle of any side (not in a corner)
* 1 
* 1 or more 
* 1 or more 
* 1 or more 
* 0-4 s, occupying the space not used by the other components
The bottom layer may also contain 1 , used to input fluid Oxygen gas for some recipes.
The control block is crafted as follows:
There are two limitations on what materials an Electric Blast Furnace can smelt: Voltage and Heat Capacity. Both are determined by the structure of the EBF.
Voltage is determined by the tier and number of es used.
Heat Capacity is determined by what were used.
* Cupronickel Coils have a Heating Capacity of 1800 Kelvin.
* Kanthal Coils have a Heating Capacity of 2700 Kelvin.
* Nichrome Coils have a Heating Capacity of 3600 Kelvin.
* Do not mix different types of Heating Coils.
GregTech Unofficial adds 4 additional tiers of Coils:
* Tungstensteel Coils have a Heating Capacity of 4500 Kelvin.
* HSS-G Coils have a Heating Capacity of 5400 Kelvin.
* Naquadah Coils have a Heating Capacity of 7200 Kelvin.
* Naquadah Alloy Coils have a Heating Capacity of 9001 Kelvin.
==Usage==
All Electric Blast Furnace recipes consume either 120 EU/t or 500 EU/t. However, as the MV Energy Hatch requires Aluminium—which can only be smelt in an EBF—to craft, the first EBF's structure must contain 3 LV Energy Hatches to prevent the machine from being overloaded. (Two would be enough ordinarily, but if any Maintenance problems are present, the EBF's energy consumption jumps from 120EU/t to 132EU/t, greater than the 128EU/t afforded by two LV Energy Hatches.)
Power is the most important issue when using an EBF. As it requires MV Electricity when only LV is available, it requires 5 Basic , , or . 5 Steam Turbines consume 510 L Steam/tick, equal to 34 , 17 s, or one fairly expensive . If a supply of Oil is readily available, a can easily supply enough Diesel to run a Blast Furnace.
One of the primary uses of the Electric Blast Furnace is the smelting of Iron into Steel. While the can also produce Steel from Iron, the Electric Blast Furnace is faster and more energy efficient. Compare the Bronze Blast Furnace smelting one Iron Ingot into one Steel Ingot in 6 minutes for 4 Charcoal as opposed to the Electric Blast Furnace smelting one Wrought Iron Ingot into one Steel Ingot in 5 seconds for approximately 20,000 EU, including Oxygen and Wrought Iron processing. Using High Pressure Coal Boilers, 4 Charcoal can produce far more than 20,000 EU.
Another important use of the Electric Blast Furnace is the smelting of Silicon Ingots, for if is installed alongside GregTech, all of its circuit recipes consume Silicon Plates. Silicon Dust can most easily be acquired by Silicon Dioxide Dust, a process which also generates 2000L Oxygen (useful for Steel or Annealed Copper). Silicon Dioxide Dust is most easily acquired by Glass Dust.
As with all other GregTech multiblock machines:
* Insufficient energy supply will destroy the currently processed material.
* When the Output Bus is full, the Electric Blast Furnace will continue to work and will destroy all newly produced items.
* Do NOT build a multiblock machine over chunk borders. Doing so can lead to unpredictable behavior. If the player has installed (which is highly recommended), chunk borders can be viewed by pressing F9 (by default).
* Before using the Electric Blast Furnace for the first time, must be performed.
* To activate or deactivate the Electric Blast Furnace, hit its control block with a .
