Electric Blast Furnace (GregTech 5)/en

The Electric Blast Furnace is a higher-tech version of the conventional Furnace. It allows higher Tier metal processing as an conventional Furnace.



Construction
The Electric Blast Furnace is a 4 block high hollow 3x3 box. The top is made from 8 Heat Proof Machine Casings around a Muffler Hatch. The Muffler Hatch must have it's exit up and must not be obscured.

The two middle layers is made from 16 Heating Coils and hollow. Use Cupnickel, Kantal or Nichrome Coils but do not mix them.

Place the Electric Blast Furnace Controller at the bottom middle.

The other bottom blocks are shared by:

1 Mainteinance Hatch

1 or more Input Bus

1 or more Output Bus

1 or more Energy Hatch

0 - 4 Heat Proof Machine Blocks for the rest. The control block is crafted as follows:

There a two points that determine what a Electric Blast Furnace can smelt: Heat Capacity and Energy Tier. Heat Capacity is changed by the used Heating Coils, Energy Tier by the used Energy Hatches.

Cupronickel Coils have a Heating Capacity of 1800 Kelvin.

Kantal Coils have a Heating Capacity of 2700 Kelvin.

Nichrome Coils have a Heating Capacity of 3600 Kelvin.

Usage
All Electric Blast Furnace receipts need at last 120EU/t. Since the MV Energy Hatch that can supply that energy needs Aluminium which is smelted by the Electric Blast Furnace itself, the first Electric Blast Furnace needs 4 LV Hatches. Each LV Hatch must be supplied by 32EU/t at 2 AMP. Insufficient energy supply will destroy the currently processed material.

Power is the most important problem with using an EBF. As it requires MV Electricity when only LV is available, it requires 5 Basic Diesel Generators, Gas Turbines, or Steam Turbines. 5 Steam Turbines consume 510L Steam/tick, equal to 34 High Pressure Coal Boilers, 17 High Pressure Lava Boilers, or one fairly expensive Large Bronze Boiler. If, however, a supply of Oil is readily available, a Distillery 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 Bronze Blast Furnace can also produce Steel from Iron, the Electric Blast Furnace is much, much faster and more energy efficient. (The Bronze Blast Furnace can smelt one Iron Ingot into one Steel Ingot in 6 minutes for 4 Charcoal. The Electric Blast Furnace can smelt 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 when Applied Energistics 2 is installed alongside GregTech, all of its circuit recipes consume Silicon Plates. Silicon Dust can most easily be acquired by electrolyzing Silicon Dioxide Dust, a process which also generates 2000L Oxygen (useful for Steel or Annealed Copper). Silicon Dioxide Dust is most easily acquired by centrifuging 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 you have NEI installed (which you should), chunk borders can be viewed by pressing F9 (by default).
 * Before using the Electric Blast Furnace for the first time, maintenance must be performed.
 * To activate or deactivate the Electric Blast Furnace, hit its control block with a Soft Hammer.
