山东省青岛市继自行车车辆厂热风转炉试验成功后,目前全市34座转炉已全部采用热风吹炼,效果显著。吹炼时间缩短了30％以上,出钢温度提高了70℃以上,可达1600℃;因此可加入大量废钢和氧化铁皮,降低了铁耗。脱硫率提高了50％以上(相对值)。同时为转炉扩大品种和提高质量创造了条件,目前已制成10种合金钢和炭素钢,钢的质量有显著提高。由此充分
Qingdao City, Shandong Province, following the success of hot-rolled converter plant bicycle test, the city’s 34 converters have all been hot-air blowing, the effect is significant. Reduce blowing time by more than 30%, tapping temperature increased by more than 70 ℃, up to 1600 ℃; so you can add a lot of scrap and iron oxide skin, reducing iron consumption. Desulfurization rate increased by more than 50% (relative value). At the same time for the converter to expand varieties and improve the quality of the conditions created, has now made 10 kinds of alloy steel and carbon steel, steel quality has significantly improved. So full
