Refractory Wikipedia

For the first half of the twentieth century, the steel making process used artificial periclase (roasted magnesite) as a furnace lining material. Magnesite refractories are composed of ≥ 85% magnesium oxide (MgO). They have high slag resistance to lime and iron-rich slags, strong abrasion and corrosion resistance, and high refractoriness under load, and are typically used in metallurgical

How is Steel Produced? World Coal Association

Any impurities may be removed through the use of fluxes and draining off slag through the taphole. Electric arc furnaces do not use coal as a raw material, but many are reliant on the electricity generated by coal-fired power plant elsewhere in the grid. Around 150 kg of coal are used to produce 1 tonne of steel in electric arc furnaces. Other steel production methods Pulverised coal injection
