湘潭钢铁厂年产平炉水冲渣(初期渣)三万多吨,含铁35～45％,其中6～7％是金属铁,余为氧化铁。这些钢渣,要占用大量农田堆放,已成为渣害,如用作铺路材料等,也是很大的浪费。湘潭钢铁厂与冷水江铁厂合作,于1973年6月和11月在冷水江铁广把水冲铜渣掺入烧结料中,进行烧结和高炉冶炼试验。在此基础上,又于1975年6月7日至20日再次进行工业生产试验。试验证 Xiangtan Iron and Steel Mill blast furnace slag with an annual output (initial slag) more than 30,000 tons, iron 35 to 45%, of which 6 to 7% is metallic iron, the remaining iron oxide. These steel slag, to occupy a large number of farmland piled up, has become a slag damage, such as used as paving materials, but also a great waste. Xiangtan Iron and Steel Plant and Lengshuijiang ironworks in cooperation, in June 1973 and November in the Lengshuijiang iron and bronze dregs into the sintering slag, sintering and blast furnace smelting test. On this basis, again in June 7, 1975 to 20 industrial test again. Test certificate
