日本日立金属公司研制成高耐磨性的压延用轧辊,它的耐磨性比目前使用的轧辊提高了5—8倍,大大延长了使用寿命,减少了更换轧辊时的停产时间,降低了生产成本。这种轧辊可以广泛用于棒钢、线材和中小型型钢的压延机。这种新型轧辊的外层采用耐磨性极高的 Japan’s Hitachi Metals developed into a high wear resistance rolling roll, its abrasion resistance than the current roll used 5-8 times, greatly extending the service life, reducing the replacement of rolls when the cut-off time and reduce production cost. This roll can be widely used for bar, wire and small and medium-sized steel rolling machine. The outer layer of this new roll is extremely wear-resistant
