一、线材生产概况目前,国内已有线材轧机80余套,其中复二重轧机40余套,年生产能力570多万吨。最近又建成投产3～4套轧机,年生产能力可增加到630万吨。但因供坯不足,1983年仅生产430余万吨,同时进口线材90万吨,全年共消费线材560多万吨。预测到1990年共需线材750～800万吨。当前尚存在缺口,还可以建设一些新线材轧机。我国线材轧机装备水平较落后,从总体
First, the wire production Overview At present, there are more than 80 sets of wire rod rolling mill, of which complex double rolling mill more than 40 sets, annual production capacity of more than 570 million tons. Recently completed and put into operation 3 ~ 4 sets of rolling mill, the annual production capacity can be increased to 6.3 million tons. However, due to insufficient supply of blanks, only 4.3 million tons were produced in 1983 and 900,000 tons of wire were imported at the same time. Over 560 million tons of wire rods were consumed in the year. It is predicted that a total of 750-8 million tons of wire will be needed in 1990. There are still gaps, but also some new wire rod mills can be built. China’s wire rod mill equipment is relatively backward, from the overall
