苏州冶金机械厂与北京钢铁学院协作,积极为中小轧钢厂挖潜改造服务,首次试制成功GY—3型(辊径φ250毫米)短应力线轧机,并已批量生产。这是适合我国小轧机技术改造的一种好方法。 GY型短应力线轧机是冶金部新技术推广的重点项目,1984年曾获得冶金部重大科技成果奖。这种轧机应用于横列式中小轧机的技术改造,可以大大提高轧材产量和精度,同时做到原有工艺、动力、基础“三不变”,因而所需的投资仅为新建同样产量轧钢车间的十分之
Suzhou Metallurgical Machinery Factory, in collaboration with Beijing Institute of Iron and Steel, has actively tapped potential tapping mills for small and medium-sized rolling mills. The trial production of the GY-3 short roll mill (φ250 mm in diameter) has been successfully completed and has been mass-produced. This is a good method for technological transformation of our country’s small mill. GY-type short-stress line mill is the Ministry of Metallurgical new technology to promote key projects, won the 1984 Ministry of Metallurgical major scientific and technological achievements award. This type of rolling mill is applied to the technological transformation of small and medium-sized rolling mills, which can greatly increase the output and precision of the rolling stock, and simultaneously achieve the “three constant” of the original technology, power and foundation, so the investment required is only for the newly-built steel rolling mill Of the tenth
