为实现冶金部轧辊分区供应的规划、四川省冶金局于1979年6月给我厂下达了“钒钛铸铁轧辊”的科研任务,要求我们利用攀枝花钢铁公司的钒钛生铁创造“钒钛铸铁轧辊”新品种、建立轧辊新体系。轧辊生产的实践证明,在轧辊中加入适量的Cr、Mo等合金会更好地提高其硬度、耐磨性、强度及热稳定性等,会更有助于提高轧辊的使用寿命。随着轧钢生产的发展,一些较先进的轧钢厂机械化程度逐步提高、轧制速度和压下量日益增大;地方性小轧钢厂雨后春笋般崛起,轧制工艺极不完善、架次太少、冷钢轧得多。这样都导致轧辊所受冲击、扭矩及磨损与日俱
In order to realize the planning of roll supply to the Ministry of Metallurgy, Sichuan Metallurgical Bureau issued a research task for “Vanadium-Titanium Cast Iron Roll” to our factory in June 1979, asking us to use vanadium-titanium pig iron from Panzhihua Iron and Steel Company to create “Vanadium- ”New varieties, the establishment of a new roll system. Roller production practice has proved that adding an appropriate amount of Cr, Mo and other alloys in the roll will be better to improve its hardness, wear resistance, strength and thermal stability, will be more helpful to improve the service life of the roll. With the development of rolling production, the mechanization of some advanced rolling mills has gradually increased, and the rolling speed and rolling reduction have been increasing. The local small rolling mills have mushroomed and the rolling process is extremely poor with too few sorties and cold Steel rolling much. This leads to roll impact, torque and wear over the day
