张力辊对带钢表面质量及卷取质量的影响分析

Analysis of the Influence of Tension Roll on Strip Surface Quality and Coiling Quality

针对重卷机组卷取质量的问题,本文从张力辊入手,分别研究张力辊材质和张力辊表面粗糙度对卷取的影响。首先对张力辊两种常用材质进行了机械性能的对比,并统计了两种涂层材料在相同应用月份带钢出现划伤的概率。然后记录了新辊表面粗糙度和旧辊表面粗糙度并进行对比分析,最后分析了卷取时的打滑原理,并通过4组试验验证了张力辊粗糙度对卷曲过程打滑的影响。

Aiming at the problem of rewinding quality in rewinding unit, this paper studies the influence of material and surface roughness of tension roll on rewinding. Firstly, the mechanical properties of two kinds of common materials of tension roll were compared, and the probability of strip scratch of two kinds of coating materials in the same application month was counted. Then, the surface roughness of the new roll and the old roll are recorded and compared. Finally, the principle of slip during coiling is analyzed, and the effect of tension roll roughness on the slip during coiling process is verified by four groups of experiments.
