上钢五厂于1984年2月份着手转炉复吹工作。3月29日,首先在2号转炉成功地进行了复吹工艺试验,到目前为止已分别在1、2号转炉上,共吹炼了7个炉役3028炉次,产量6.05万吨。为了克服底吹枪龄短的缺点,同时也为了能随时变换底吹枪形式,适应冶炼不同钢种的需要,进行了调换底枪的试验,并获得圆满成功。经过反复试验,逐步摸索出一套较为切实可行的转炉复吹工艺。 Wuchang on the steel in February 1984 to start the work of BOF. March 29, the first successful in the No. 2 converter complex blowing process test, so far have been in the No. 1 and No. 2 converter, a total of 7 furnaces furnace blowing 3028 furnaces, the output of 60,500 tons. In order to overcome the shortcomings of the short blower at the end of the blow, but also in order to be able to change at any time, the type of bottom blowing lance, smelting different steel to adapt to the needs of the replacement of the gun test, and was a complete success. After repeated tests, gradually developed a set of more practical converter blowing process.
