当前国外在连续铸钢机上大量生产沸腾钢的工厂为数不多,据报导,除苏联及美国麦克劳特公司已经在连铸机上大量生产沸腾钢以外,其他国家还正在进行试验研究工作。英国的爱浦贝佛鲁底汉公司及巴路钢铁公司都进行了试验,结果没有成功。我们为了掌握在连铸机上浇注沸腾钢的工艺,以使炼钢车间全部连铸化,为取消钢锭模浇注提供条件。65年11、12两月先后在5吨纯氧顶吹转炉炼制三号沸腾钢,在连铸机上浇成200毫米方坯,取得了令人满意的结果,并获得一次不间断连续浇注三炉钢的成绩。首批铸坯经中型轧钢车间轧成60毫米方坯,再经小型车间轧成16毫米圆钢,经鉴定,质量良好。
At present, there are only a few factories producing large quantities of boiling steel in continuous casting machines overseas. It is reported that other countries, besides the Soviet Union and the United States, have already mass-produced boiling steel on the continuous casting machine. Other countries are also conducting experimental research. Experiments were carried out in the United Kingdom with Appenody and the Baruch Steel Company. The result was unsuccessful. In order to grasp the process of pouring boiling steel on the continuous casting machine, all of the steelmaking workshops are continuously casted to provide the conditions for eliminating the ingot casting. 65 years in November and November two two successively in 5 tons of pure oxygen top-blowing converter No.3 boiling steel, casting machine into a 200 mm billet, and achieved satisfactory results, and received an uninterrupted continuous casting three Furnace steel grades. The first billet was rolled into 60 mm billet by a medium-sized rolling mill and then rolled into a 16 mm billet by a small workshop. After being identified, the quality was good.
