信德电化厂是生产电石的工厂,今年七月为支持钢铁生产改生产矽铁。主要生产设备有:400KVA熔炉变压器一台、三相电炉一座、电碾一座、电极设备一座,生产工人18人。电炉是用普通耐火砖砌成,炉子直径为1800公厘,高1000公厘。炉底是由炭素材料捣成,呈微斜的碗形,以便还原的矽铁水易于流出,三相电极排列为三角形。用人工加料。日产矽铁约700公斤,每吨成本约1290元,耗电约一万瓩小时。冶炼矽铁的主要原料是:石英石、焦炭、钢屑。对原料的要求:
Sindh Electrochemical Plant is a factory producing calcium carbide, iron ore production in July this year to support the production of ferrosilicon. The main production facilities are: a 400KVA furnace transformer, a three-phase electric furnace, electric grind a, a electrode equipment, production workers 18 people. Electric furnace is made of ordinary refractory brick, furnace diameter of 1800 mm, 1000 mm high. The bottom of the furnace is made of carbon material, with a slightly inclined bowl shape, so that the reduced silicon water is easy to flow out and the three-phase electrodes are arranged in a triangular shape. Use manual feeding. About 700 kilos of ferrosilicon are produced each day, with a cost of about 1,290 yuan per ton. The power consumption is about 10,000 hours. The main raw material for smelting of ferrosilicon is: quartz, coke, steel scrap. Requirements for raw materials:
