The EAF is different from the blast furnace as it produces steel by using an electrical current to melt scrap steel, direct reduced iron, and/or pig iron, to produce molten steel. (Apologies for lousy sound compression.)With power now resolved (for the time being) it's time to set up electric furnaces. The use of EAFs has expanded and now accounts for over 70 percent of steel production in the United States. The first electric arc furnaces (EAFs) appeared in the late 19th Century. Today, natural gas is increasingly being added in place of coke to the same degree in the blast furnace to reduce carbon emissions. 0 Krastorio 2 Compact 36 Matter/s from water (2160/min) 1 Woodburner 2700 mk4. The strong pieces of coke with a high energy value provide permeability, heat and gases which are required to reduce and melt the iron ore, pellets and sinter. The coke is a porous, hard black rock of concentrated carbon (contains 90 to 93 percent carbon), which has some ash and sulfur but compared to raw coal is very strong. The coke is cooled and screened into pieces ranging from one inch to four inches. The cooked coal, called coke, is removed from the oven after 18 to 24 hours of reaction time. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800☏ in the absence of oxygen. The blast furnace uses coke, iron ore and limestone to produce pig iron.Ĭoal traditionally has been a key part of the coke-making process. generally require any additional ancillary equipment as with other electric steam boilers. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. Factorio is a game in which you build and maintain factories.

The first blast furnaces appeared in the 14th century and produced one ton per day.

The blast furnace is the first step in producing steel from iron oxides. Steel is primarily produced using one of two methods: Blast Furnace or Electric Arc Furnace.
