近二十年来高速无扭精轧机组和轧后控制冷却技术的应用,使线材生产轧制速度由35～40米/秒提高到75～85米/秒(最高已达100米/秒),坯料断面尺寸由85×85～90×90毫米扩大到125×125～140×140毫米,盘重由500～600公斤增大到1500～2500公斤。线材生产技术的进步,已经成为现代轧制技术的重要组成部分。 经控制冷却技术处理的线材作为一种新产品深受用户欢迎其主要原因就在于: In recent twenty years, the application of high speed untwisted finishing mill and post rolling cooling control technology has increased the wire production and rolling speed from 35 to 40 m / s to 75 to 85 m / s (up to 100 m / s) Billet cross-sectional size from 85 × 85 ~ 90 × 90 mm expanded to 125 × 125 ~ 140 × 140 mm, weight from 500 to 600 kg increased to 1500 to 2500 kg. The advancement of wire production technology has become an important part of modern rolling technology. Controlled by the cooling technology to deal with the wire as a new product welcomed by users The main reason is that:
