There are many ways to smelt low-carbon ferrochromium. Do you know about the electrosilicothermal method? Here is a summary of the relevant knowledge about smelting low-carbon ferrochromium to see if it is helpful to you.
The smelting of low- and medium-carbon ferrochromium by electrosilicothermal method is carried out in a stationary three-phase electric arc furnace. Self-baking electrodes can be used, and the furnace lining is dry-built with magnesia bricks. Short furnace lining life is an important problem in the production of medium and low carbon ferrochrome. Due to the high smelting temperature of 1650 degrees Celsius, the furnace lining life is generally shorter.
The raw materials for smelting medium-low carbon ferrochrome include chromium ore, silicon-chromium alloy and lime. Chrome ore should be dry and pure lump ore or concentrate powder, in which the higher the Cr2O3 content, the better, and the lower the impurity content, the better. The phosphorus content in chrome ore should not be greater than 0.03%, and the particle size should be less than 60mm. The silicon-chromium alloy should be crushed, with a particle size less than 30mm and no slag. The lime should be freshly burned and its CaO content should be no less than 85%.
