1 前言我国线材制品行业拥有650多家生产企业,其中生产中高碳钢丝、钢丝绳的约有150多家,具有相当规模的80多家。由于线材制品属深加工、劳动密集型产品,具有相对投资少、建设周期短、投资回收期短、经济效益好的特点。10几年来,线材制品行业取得了很大发展,全国生产能力已达300×10~4t/a,特别是长期供不应求的中高碳制品,产量已从1980年的35.8×10~4t,提高到1991年的83.3×10~4t,年递增8％,生产能力达到93×10~4t;
1 Introduction China’s wire rod industry has more than 650 manufacturing enterprises, including the production of high-carbon steel wire rope about 150, with a considerable size of more than 80. As wire products are deep processing, labor-intensive products, with relatively less investment, construction period is short, short payback period, good economic returns. In the past few years, the wire rod product industry has made tremendous progress. The national production capacity has reached 300 × 10 ~ 4t / a, especially for medium and high carbon products, which have long been in short supply. The output has risen from 35.8 × 10 ~ 4t in 1980 to 1991 Year 83.3 × 10 ~ 4t, annual increase of 8%, the production capacity of 93 × 10 ~ 4t;
