摘要

初轧厂650轧机轧辊与高温下的轧材表面接触时

在工作压力、冲击、磨损和热循环的综合作用下会产生辊面龟裂和孔型磨损

为避免轧材尺寸和表面质量受到影响

需及时更换轧辊。采用埋弧焊堆焊修复工艺修复更换下来的轧辊

修复的轧辊必须满足使用要求

即辊面具有较高硬度和高温耐磨性

因此焊接材料的选用及合理焊接工艺的制定非常重要。

Abstract

In a rough rolling mill

when the 650 roller contacts with the surface of the rolled material at a high temperature

the roller surface may crack and roller pass may wear due to the combined action of working pressure

impact

wear and thermal cycle. Thus

the roller should be replaced timely. The repair technologies of submerged-arc welding and surfacing are widely used to repair the replaced roller.The repaired roller must satisfy the use requirements

namely the roller surface must have high hardness and high temperature wear resistance

so it is very important to select welding materials and develop a reasonable welding technology.
