我厂自1952年试用球墨铸铁浇铸轧辊以来,先后试制数次,并经生产上实际应用,证明铸成的轧辊完全可以代替一般铸钢的或冷铸的轧辊。现将我厂浇铸轧辊过程、物理性能及生产上使用情况简要介绍如下。 Since the trial of ductile iron casting roll in 1952, our factory has trial-produced several times successively and has been practically applied in production, which proves that the casting roll can replace the general-cast or chilled roll. Now I plant casting roll process, the physical properties and production on the use of a brief introduction is as follows.
