1986年钢5206万吨,比1985年增长527万吨。在钢增产的同时,各企业近八年来,坚持不懈地抓紧提高钢锭成坯率和提高综合成材率工作,使成坯率、成材率逐年增长。目前,在我国连铸比尚不高的情况下,继续抓紧钢锭成坯率的措施落实,是提高成材率的重要环节。几年来,首先抓了热帽技术和液芯钢锭加热和轧制技术的不断完善
Steel amounted to 52.06 million tons in 1986, an increase of 5.27 million tons over 1985. In the steel production increase at the same time, all enterprises in the past eight years, unremittingly pay close attention to improve the ingot into the blank rate and improve the overall rate of finished product, so that into the blank rate, the rate of increase year by year. At present, continuous casting in our country is still not high, continue to pay close attention to the blank ingot rate of measures to implement, is to improve the rate of success of an important part. Over the past few years, first caught the hot hat technology and liquid steel ingot heating and rolling technology continues to improve
