1991年底,冶金系统投产和在建高速线材轧机共有20套28条生产线,设计生产能力为472万吨。已投产的有24条,包括引进设备15条线,国产设备9条线,设计能力为401万吨。1991年产量达到302.9万吨,达产率为75.5％。 这批高速线材轧机的陆续投产,标志着我国线材生产技术装备、产品质量提高到一个新水平,缓解了线材的供需矛盾。在高速线材轧机投产前的1980—1987年里,我国平均每年进口线材285万吨,为同期线材产量的46.87％。新轧机陆续投产后,1988年进口量降到96.8万吨(占线材总产量的12.29％),1991年又降到8.87万吨(占线材总产
At the end of 1991, a total of 20 sets of 28 production lines were put into operation for the metallurgical system and the high-speed wire rod mill under construction with a designed production capacity of 4.72 million tons. Has been put into operation 24, including the introduction of 15 lines of equipment, domestic equipment 9 lines, design capacity of 4.01 million tons. In 1991, the output reached 3.029 million tons, reaching a yield of 75.5%. These high-speed wire rod mill put into operation one after another, marking China’s wire rod production technology and equipment, product quality to a new level, eased the contradiction between supply and demand of wire. In the period from 1980 to 1987 before the high-speed wire rod mill was put into operation, China imported an average of 2.85 million tons of wire a year, accounting for 46.87% of the total output of wire rod in the same period. After the new rolling mill was put into operation one after another, the import volume dropped to 968,000 tons in 1988 (accounting for 12.29% of the total wire output) and dropped to 88,700 tons in 1991 (accounting for the total output of wire products
