摘要 |
<p>The surface of a roll has built-up weld layers which are arranged in bent waves such that the growth of initial fine cracks which occur on the surface of a roll are prevented. The surface of the built-up weld layer is finished smoothly so that the wavy weld beads prevent the growth of initial fine cracks.</p> |
