The selection of a charging carbon is determined by the quality requirements of the steel or ferroalloy production e as well as the cost and availability of carbon products. Due to its high carbon content, low and consistent S/P content, and its porous structure, which allows hot metal to enter the tiny fissures to devour its carbon content quicker, coke is always the best choice for the furnace operation in slag foaming or in carbon adjustment, not mention the less costly and convenient.
