最近,冶金部在石钢召开了配煤技术革命会议,重点总结了包钢、石钢炼焦配煤技术革命经验。纪要如下:一、关于炼焦配煤技术革命的估价自从贯彻调整方针以来,我国炼焦工作者改革了过去以主焦煤为主的配煤方法。全国重点企业主焦煤配比,1961年为32.5%,1964年为25%,平均降低7.5%;焦炭灰份1961年为16.85%,1964年为13.68%,平均降低3.17%。按年产一千万吨钢计算,可以节约二百万吨主焦煤,同时使资源利用更加合理,使炼焦生产实现多、快、好、省,并且解决了今后钢铁工业大发展中的一个重要问题。
Recently, the Metallurgical Department held a coal blending technology revolution meeting in ShiGang, especially focusing on the experience of technology revolution in the coke blending with Baosteel and ShiCang. The minutes are as follows: I. Valuation of the Technological Revolution of Coking and Coal Bleeding Since the implementation of the adjustment guidelines, the coking workers in our country have reformed the coal blending methods mainly based on the main coking coal. Coking coal ratio of key state-owned enterprises in the country was 32.5% in 1961 and 25% in 1964, an average reduction of 7.5%. The coke ash content was 16.85% in 1961 and 13.68% in 1964, with an average reduction of 3.17%. Calculated according to an annual output of 10 million tons of steel, it can save 2 million tons of main coking coal and at the same time makes resource utilization more reasonable, so that the coking production can be realized more quickly, efficiently and economically and an important issue in the future development of the steel industry is solved problem.
