本文根据冲天炉中的冶金还原反应原理,国内首次采用资源丰富,价廉的硼矿石在炉后加入,代替昂贵的硼铁合金,生产大、中型机床硼耐磨铸铁件。取得显著的经济效益,具有推广应用价值。
According to the principle of metallurgical reduction reaction in cupola, the boron rich iron ore which is rich in resources and cheap in China is added for the first time in the furnace instead of expensive boron ferroalloy to produce boron wear-resistant cast iron parts for large and medium-sized machine tools. Obtain significant economic benefits, with the promotion and application value.
