钢屑、铁屑投炉熔炼是一项十分经济的技术措施。我厂二十多年来已用“双肩” 117300吨,代废钢十多万吨,节省成本费达800万元。此项措施可省废钢、生铁、电力;有利于造渣、加快熔化速度、保护炉衬、炉盖;且可降低铸件成本。炼钢用的“双屑”必须除去锈蚀和夹带的泥砂。如处理不当,会增加熔炼过程困难,增加消耗量,并影响钢水质量。要求对“双屑”必须及时回收、发运、加工、配料。配加量可 Steel scrap, iron scrap investment furnace smelting is a very economical technical measures. I plant more than 20 years have been “shoulders” 113,700 tons, on behalf of scrap steel more than 100,000 tons, cost savings amounted to 8000000 yuan. This measure can save scrap, pig iron, electricity; is conducive to slagging, speeding up the melting rate, to protect the lining, lid; and can reduce the cost of casting. Steelmaking “double shavings” must remove rust and entrained sand. Improper handling can increase the melting process, increase the consumption and affect the quality of the molten steel. Require “double shavings” must be promptly recovered, shipped, processed, ingredients. With the amount can be
