煤氧熔化废钢的热态试验表明，煤氧枪熔化废钢的试验工艺是可行的。四种工艺中，采用坚炉、炉壁侧煤氧枪加二次燃烧的d型工艺的技术指标最好。此类工艺的开发具有较大现实意义。
The thermal tests of coal-oxygen molten steel show that it is feasible to test the melting process of coal-oxygen steel scrap. Among the four kinds of techniques, the technical indexes of the d-type process using strong furnace, side-wall coal-fired oxygen gun plus secondary combustion are the best. The development of such technology has great practical significance.
