轧辊的低辊耗技术

焊辊断辊减少了焊辊的使用次数．通过对断辊分析，发现引发断辊的原因是堆焊前基体存在严重裂纹和堆焊缺陷．对此提出采用激光系统强化技术使孔型各部位均衡磨损，延长轧辊的单次使用寿命；采用定量轧制管理可避免轧槽过度磨损萌生无法铲除的裂纹；为确保堆焊质量，采取保护渣质量管理和堆焊缺陷及时修复的措施．上述系统解决方案的实施．可增加焊辊使用次数，大幅降低辊耗。

Technique on low consumption of roller

Usage times of the overlay welded miler are reduced owing to its breakage in service. It is found by analyzing the broken roller that the roiler breakage is resulted from severe cracks of base material and overlaying defects. Based on the observation and investigation on the spot, the method of adopting laser transformation hardening technique to reach the goal of uniform wear in every part of the groove and prolong the single service life of roller is put forward. The management of quantitative rolling is adopted to prevent the irremovable cracks from over wear of the groove. The measure of management of protection slag quality and timely repair of the defects brought by overlaying is adpoted to enssure the surfacing quality. After these system solutions are carried out, the usage times of overlay welded roller is increased and roller consumption is decreased greatly.
