1.现状1983年以来,我国10个厂先后从六个国家引进高速线材轧机(16条线,年生产能力340×10~4t),包括了当今世界流行的四种主要机型:美国摩根公司侧交45°轧机,英国阿希洛公司顶交45°轧机,西德迪马克公司15/75°轧机及意大利达涅利公司平立交替高速线材轧机。同时,有9个厂已建成或即将建成国内自制的高速线材轧机(11条线,年产能力97×10~4t)。上述19个厂共计27条线,年产能力437×10~4t,全部形成生产能力后相当于1989年全国线材产量的50％,见表1。
1. Status Quo Since 1983, 10 factories in China have successively introduced high-speed wire rod rolling mill (16 lines with an annual production capacity of 340 × 10 ~ 4t) from six countries, including the four major models popular in the world today: Morgan Stanley 45 ° cross-rolling mill, the United States Achiluo 45 ° top mill cross, West Germany Mark 15/75 ° mill and Italy Danieli company Pingli high-speed wire rod mill alternately. At the same time, 9 plants have built or will soon be built domestically made high-speed wire rod mill (11 lines with an annual production capacity of 97 × 10 ~ 4t). The above-mentioned 19 plants total 27 lines, with an annual production capacity of 437 × 10 ~ 4t, which is equivalent to 50% of the national wire production in 1989 after all the production capacity has been formed, as shown in Table 1.
