在遵义铁合金厂党的核心小组的领导下,吹氧组全体同志在各兄弟车间科室的密切配合下,1975年8月28日至9月25日在同年、五月间试验的基础上,连续进行了中炭锰铁的吹氧法试验。此期间共吹炼了28炉,共得合格产品10929公斤,其中一级品为2500公斤。合格率达83.5%,一级品率占19.1%。此期间操作较过去熟练,对吹炼规律性的认识也深入了,基本上消灭了大喷渣现象。试验证明可以不加任何冷却剂,炉渣碱度达1.5—2,在装入量合适的条件下,也可克服喷渣而顺利完成操作。目前存在的主要问题是回收率略低,为消除公害而急需解决除尘
Under the leadership of the core group of the Zunyi Ferroalloy Factory Party, all comrades in the oxygen blowing group, working closely with the departments of the brothers’ workshops, conducted a series of experiments on August 28 to September 25, 1975 in the same year and in May on a continuous basis Carried out in the carbon ferromanganese oxygen blowing test. During this period a total of 28 furnaces were blown, a total of 10929 kilograms of qualified products, of which 1,500 kilograms of goods. Pass rate of 83.5%, a product rate of 19.1%. Operation during this period than the past proficiency, understanding of the regularity of blowing has also deepened, basically eliminated the phenomenon of large spray slag. Test proved that without any coolant, slag alkalinity of 1.5-2, in the right amount of loading conditions, but also to overcome the slag and the successful completion of the operation. The main problem currently existing is the slightly lower recovery rate, which is urgently needed to solve the problem of dust removal
