Steel making: Difference between revisions

==Required facilities== <!--T:46-->

To produce {{ll|steel|steel}}, a player needs an iron {{ll|anvil|anvil}}, a {{ll|forge|forge}}, and a refactory cementation rurnace building, which itself will require a {{ll|pulverizer|pulverizer}}.

===Required materials=== <!--T:47-->

To build a functioning cementation furnace, the player needs 1 iron door, 2 stone coffin sections and 2 stone coffin lids, 6 refractory brick gratings, 53 refractory brick blocks and a number of dirt or stone blocks to build the coal burning area beneath the furnace structure itself. The minimum raw ingredients for these items are listed below.

===Creating refractory bricks=== <!--T:49-->

Refactory blocks are important for the steel making process as no other currently available block can withstand the extreme heat necessary to produce {{ll|steel|steel}}. Refractory blocks come in three different tiers, all of which can be used to make the cementation furnace. All refractory brick blocks have a chance to receive damage per use of the cementation furnace smelting process, however, using higher tier blocks will reduce the amount that receive damage per use. Tier 1 has a heat resistance of 90% (1 in 10 chance to break), tier 2 95% (1 in 20 chance to break), and tier 3 99% (1 in 100 chance to break). (Tier 3 may actually have a heat resistance of 99.9% and thus a 1 in 1000 chance to break. This information needs verification.)

Raw refractory bricks need to be baked in a {{ll|pit kiln|pit kiln}} to turn into fired refractory bricks.

Fired refractory bricks can then be used to craft their tier specific '''brick blocks''' and '''brick grating blocks'''. Here are the recipes for tier 1:

===Other required blocks=== <!--T:58-->

Additionally to the refractory blocks, there are some more specialist blocks necessary to build a functioning steel making furnace, namely an '''iron door''' and a '''stone coffin''' including a '''coffin lid'''.

And iron door can either be found in ruins, or crafted out of 6 iron plates. Stone coffins can be made out of {{ll|granite|granite}}, {{ll|andesite|andesite}}, {{ll|basalt|basalt}} or {{ll|peridotite|peridotite}}.

==The structure== <!--T:60-->

#First, place the 6 grate blocks on the ground and the 2 coffin sections on them. These are the center blocks of the structure. The coffin sections will always be placed with the open side towards the player. As soon as the full coffin is placed - without coffin lid, for now - the player can use {{Keypress|Shift}} + {{RMB}} on the coffin to display the building help.

#The full size of the furnace takes up a 5x5 space that is 6 blocks tall, however, an additional layer below the grates will be required to place fuel in.

==Creating blister steel== <!--T:63-->

Blister steel is the first step of creating steel from iron, and functions the same way an iron bloom does. To heat iron up to the required temperatures to make carbonization possible, the player first needs to build a special furnace structure out of refractory blocks and other specialist blocks.

Also, prepare a ''lot'' of charcoal, or collect a lot of black coal. One batch of steel will use 168 pieces of charcoal.

===Smelting process=== <!--T:64-->

With a finished refractory furnace build, the next step requires the player to fill the coffin.

One stone coffin will hold a total of 16 iron ingots and 40 fuel pieces - either {{ll|coke|coke}} or {{ll|charcoal|charcoal}}. With the fuel in your active hand, target the inside the coffin and use {{Keypress|Shift}} + {{RMB}} to place one layer of fuel first, then one layer of iron ingots. Repeat until the coffin is full and will not accept any more items. The coffin should allow 5 layers of fuel with 8 pieces per layer, and 4 layers of iron ingots with 4 ingots per layer.

==Trivia== <!--T:72-->

The design of the refractory furnace is a modified version of the ''Manuel de la métallurgie du Fer'', from 1895 [https://upload.wikimedia.org/wikipedia/commons/2/23/Four_cementation_anglais.jpg]
