The silicon-manganese alloy smelting method comprises the steps that S1, a control unit controls a raw material conveying unit to convey a manganese-containing raw material stored in a raw material storage box into a smelting furnace to be smelted so as to prepare a liquid manganese mixture, and when the raw material is conveyed, the liquid manganese mixture is separated from the raw material storage box; the control unit controls the preheating unit to heat the raw materials to a preset value; s2, the control unit controls a raw material conveying unit to convey silicon-containing raw materials stored in a raw material storage box into a smelting furnace for smelting so as to prepare a liquid silicon mixture, and when the raw materials are conveyed, the control unit controls a preheating unit to heat the raw materials to a preset value; and S3, the liquid manganese mixture prepared in the step S1 and the silicon mixture prepared in the step S2 are mixed and remelted to prepare the silicon-manganese alloy, energy consumption can be effectively reduced, meanwhile, the preheating efficiency of raw materials can be effectively improved, and the alloy smelting efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of alloy smelting, in particular to a silicon-manganese alloy smelting method based on the recycling of waste slag. Background technique [0002] Silicon-manganese alloy is an alloy composed of manganese, silicon, iron, a small amount of carbon and other elements. Ferro-manganese alloy containing enough silicon is called silicon-manganese alloy. It is a ferroalloy with wide application and large output. Silicon-manganese alloy is a compound deoxidizer commonly used in steelmaking, and it is also a reducing agent for the production of medium and low-carbon ferromanganese and the production of metal manganese by electrosilicothermal method. In addition, as an alloying agent for steelmaking, it is added to steel to improve the mechanical properties of steel, increase the strength, hardness, ductility and wear resistance of steel, etc. Therefore, it is widely used in steelmaking in metallurgical enterprises, an...
