前言吹氧法炼中炭锰铁的试验是1975年在遵义铁合金厂开始的。试验开始以来,厂中试室党支部领导了全车间的工人、干部和技术人员团结一致,努力奋斗,在1975年已取得了初步成果,之后又对设备进行了改进,于1977年进行了系统试验。在英明领袖华主席亲自主持的全国工业学大庆会议的东风的鼓舞下,试验取得了很大成果。锰回收率由1975年试验的65～70%提高到75—80%(提高10%)这是一个很大的成绩,但事物总是一分
Preface The practice of oxygen blowing refining carbon ferromanganese test was started in 1975 in Zunyi ferroalloy plant. Since the beginning of the experiment, the Party Branch of the pilot laboratory in the factory has led the workers, cadres and technicians in the entire workshop to unite and work hard. Preliminary results have been achieved in 1975 and the equipment has been improved since then. In 1977, the system test. Inspired by the east wind of the National Industrial Science Daqing Conference presided over by Chairman Hua himself, the wise leader achieved great results. Manganese recoveries increased from 65-70% in 1975 to 75-80% (up 10%) This is a big achievement, but things are always a fraction
