我厂生产高压输电线路可锻铸铁金具及超高压线路部分重要电气组装铸件。为提高可锻铸铁质量作了一系列小型试验,取得了改善金相组织、提高机械性能和减少能耗的显著效果。一、试验条件 (一)熔炼及处理工艺: 用3吨热风冲天炉熔炼铁水,炉料用本省生铁10％,废钢45％,回炉铁45％。用手抬小包冲入法

I plant the production of high-voltage transmission lines malleable iron and ultra-high voltage lines and some important electrical assembly castings. In order to improve the quality of malleable cast iron, a series of small-scale experiments have been carried out and remarkable results have been obtained in improving the microstructure, improving the mechanical properties and reducing the energy consumption. First, the test conditions (a) smelting and treatment process: 3 tons of hot air cupola smelting hot metal, iron ore with 10% of the province, scrap 45%, 45% iron back.
