世界上最大直径的硬质合金轧辊近日在株洲硬质合金厂开发成功,该厂日前按合同向用户发出了首批新产品。 硬质合金轧辊耐磨性好,轧制能力强,是钢材轧机上的重要部件。长期以来,我国一些大型钢厂使用的大轧辊都要依赖国外进口,价格昂贵,增加 The world’s largest diameter carbide roll has recently been successfully developed in Zhuzhou Carbide plant, the plant recently issued to the user under the contract the first batch of new products. Carbide roll wear resistance, rolling ability, is an important part of the steel mill. For a long time, some large-scale steel mills in China have to rely on large-scale imports of foreign imports, expensive, increasing
