我厂线材车间专门轧制φ5.5～7毫米的盘元。由于轧制时线速度较高,成品辊每分钟近达千余转,因此在辊颈上装置滚珠轴承,精轧机组的轧辊是采用辊身带有白口的冷硬铸铁所制成,在使用时辊颈轴承挡很容易磨损。长期以来,轴承挡磨损后的修复是采用金属喷镀的办法来解决的,但随着生产的不断发展,产量迅速上升,轧辊在工作时所承受的冲击负荷大为增加,由于喷镀层和轧辊本身并不熔合在一起,因此往往在正常生产过程中喷镀层碎裂而把轴承胀死,因此
I plant wire workshop specializing in rolling φ5.5 ~ 7 mm disk yuan. Due to the high linear velocity during rolling, the finished roller reaches nearly a thousand revolutions per minute, so the ball bearing is arranged on the roll neck. The roll of the finishing rolling mill is made of chilled cast iron with a white roll in the roll body. Roller-neck bearing stops wear easily when used. For a long time, bearing wear after repair is the use of metal spraying method to solve, but with the continuous development of production, the rapid increase in output, the roll at work to withstand the impact load is greatly increased, as the spray coating and roll Itself is not fused together, so often in the normal production process of spray coating cracks and the expansion of the bearing, so
