摘　　要：窄边铜板弯月面处热面边角部有最高温度和最大的应力集中,导致该处的塑性变形或蠕变也最严重,这是窄边铜板弯月面处产生宽度收缩的根本原因,作为窄边铜板长寿化的有效措施是强化边部冷却,求得同一水平内的冷却均匀化,并在铜板正面使用Ni基自熔合金热喷涂涂层。There will be maximum temperature and stress centralizing on the mentiscus at corners andedges of narrow face copper plates. It can result in the most serious plastic strain or creep which is themain cause of width shrinkage on mentiscus at narrowface copper plates. The offective measures makingnarrow face long life include improvement of edge cooling for uniform cooling at the same level andapplication of hot spray with Ni self-fusible alloy on the front face of copper plates.
