Smelting of stainless steel: one-step process

That is, the electric furnace smelts stainless steel in one step. Due to the one-step method has strict requirements on raw materials (stainless steel scrap, low-carbon ferrochrome and metallic chromium need to be returned), the consumption of raw materials and energy media in production is high, the cost is high, the smelting cycle is long, the productivity is low, the product variety is small, the quality is poor, and the life of the furnace lining Short, high consumption of refractory materials, so this method is rarely used to produce stainless steel.
