上海冶金设计研究院和上钢五厂、二机修厂吸收国外第三代短应力线、预应力结构的高刚度轧机的优点,设计了WPF500高刚度轧机。于1988年2月底进行了热负荷生产,到目前为止,该轧机运转稳定,产品精度大为提高,劳动强度大大降低。 Shanghai Metallurgical Design and Research Institute and the steel plant on the 5th, the second machine repair plant to absorb the third generation of short-term stress lines abroad, prestressed structure of the advantages of high-stiffness rolling mill designed WPF500 high-rigidity mill. At the end of February, 1988, heat load production was carried out. So far, the mill has been operating steadily, product accuracy has been greatly improved, and labor intensity has been greatly reduced.
