我国自己设计制造的第一台45°小辊径高速无扭线材精轧机已进入工业性生产试验阶段。这台轧机是上钢二厂和北京钢铁设计总院等单位联合设计制造的。它的特点是:轧辊直径小,轧制速度高,延伸大,轧出的线材精度高。采用悬臂结构,设备紧凑,运转平稳,封闭轧制,劳动环境优良。是我国线材工作者盼望已久的先进设备。 China’s own design and manufacture of the first 45 ° small diameter high-speed non-twisted wire rod mill has entered the stage of industrial production test. This mill is a steel plant and Beijing Iron and Steel Design Institute and other units jointly designed and manufactured. It is characterized by: small roll diameter, high rolling speed, extended, rolled out of the wire high precision. Cantilever structure, compact equipment, stable operation, closed rolling, excellent working environment. Wire workers in China is the long-awaited advanced equipment.
