高铬复合矫直辊

HI-CR COMPOUND STRAIGHTENING ROLL

介绍了高铬复合矫直辊的研制及其使用情况。实践表明,使用高铬复合矫直辊轧制钢管和型钢其寿命比冷硬铸铁矫直辊高20～50倍,比锻钢矫直辊高2～10倍。

The development and operation practise of the Hi-Cr compound straightening roll are introduced in the article. The practice has brought a conclusion that for rolling steel tubes or sections, the Hi-Cr compound straightening roll has a service life 20-50 times longer that the coldhardened cast rion straightening roll and 2-10 times longer than the forged steel straightening roll.
