冷弯型钢与通常的热轧型钢相比,具有很多独特的优点,例如:机械加工量少,尺寸精度高、断面型状合理、单位重量的断面系统数高、品种多样……等,因此,一些发达的国家都在大力发展冷弯型钢生产,其产量占全部钢材产量5％。我国60年代才开始发展冷弯型钢生产。目前全国有10多套冷弯型机组,能力近20万吨,产量仅占钢材总产量的0.8％,供需矛盾还十分突出。根据以上情况,建议我省在“八五”后三年着力发展冷弯型钢生产。
Compared with ordinary hot-rolled steel, cold-formed steel has many unique advantages such as less machining amount, high dimensional accuracy, reasonable sectional shape, high number of cross-section systems per unit weight, variety, etc. Therefore, Some developed countries are vigorously developing cold-formed steel production, its output accounted for 5% of total steel production. China’s 60s began to develop cold-formed steel production. At present, there are more than 10 sets of cold-formed units in the country, with a capacity of nearly 200,000 tons. The output only accounts for 0.8% of the total output of steel products, and the contradiction between supply and demand is still outstanding. Based on the above, I suggest that the province focus on the development of cold-formed steel production in the third year after the Eighth Five-Year Plan.
