The invention relates to a manufacture method for siliconmanganese that uses rotary kiln sintering powder and hot charges into mine thermoelectricity furnace. It includes the following steps: mixing, sintering powder, hot charging the 5-70mm diameter powder into mine thermoelectricity furnace and the furnace temperature is 680-900 degree centigrade, melting for 6h to generate siliconmanganese mixed solution and draw a charge, separating the dregs and iron, and casting the alloy molten iron into die equipment. |
