在制造变形复杂的钢板结构件时,必须满足各种综合要求。对于作为原材料的冷轧薄钢板来说,要求其具有良好的成型性以及稳定的表面质量。这就要求冷轧机工作辊表面的微细结构要尽可能长时间的保持不变。本文证实通过工作辊表面的渗铬硬化层可以满足上述要求。
In the manufacture of complex deformation of steel structures, must meet a variety of comprehensive requirements. For a cold-rolled steel sheet as a raw material, it is required to have good formability and stable surface quality. This requires that the surface of the cold rolling mill work fine structure as long as possible to maintain the same. This paper confirms that the above requirements are satisfied by the chromic hardened layer on the work roll surface.
