唐山钢厂顶吹氧气转炉于1月15日、16日和2月7日、8日在东北工学院教师、涟源钢铁厂、武汉、马鞍山黑色冶金设计院协同配合下先后进行了四次喷吹石灰粉试验,共试吹28炉,获得初步成功。顶吹氧气转炉喷吹石灰粉炼钢,是近年来发展起来的一种新的转炉炼钢工艺。虽然国外已有几年生产的历史,但在国内尚无先例可循。这次试验的成功,在国内还是首创。它对我国丰富的含磷较高的磷铁矿资源的利用提供了
The top-blowing oxygen converter of Tangshan Iron and Steel Plant was carried out four times on January 15, 16 and February 7 and 8 respectively with the cooperation of Northeast China Institute of Technology teachers, Lianyuan Iron and Steel Plant, Wuhan and Ma’anshan Black Metallurgical Design Institute. Blowing lime powder test, a total of 28 stoves were tried to obtain initial success. Top blowing oxygen converter injection lime powder steel, is developed in recent years, a new converter steelmaking process. Although there are several years of foreign production history, but no precedent in the country to follow. The success of this experiment is still the first in China. It provides our country with ample use of high-phosphorus-bearing phosphate rock resources
