为充分利用废料,降低金属料消耗,曾在一应用热装矿石法的15吨平炉上,采用重量比30%的轧钢铁鳞和40%的转炉喷溅物代替装料铁矿石,炼制20炉沸腾钢。试验结果表明:对钢的质量,冶炼操作和炉体寿命并无不良影响。计算经济价值结果指出:一个有4座15吨平炉的企业,每年可从抛弃的废料中为国家创造财富约454万元。 In order to make full use of wastes and reduce the consumption of metal materials, iron ore was cast on a 15-ton open hearth furnace with a weight of 30% and 40% converter splatter instead of charging iron ore, refining 20 furnace boiling steel. Test results show that: the quality of steel, smelting operations and furnace life without adverse effects. Calculating Economic Value The results show that a 4-tonne 15-ton open hearth furnace can generate about 4.54 million yuan of wealth each year from abandoned waste.
