冷轧薄板表面缺陷研究 总被引:3,自引:0,他引:3
介绍了冷轧薄板表面主要缺陷的形貌、形成原因及预防措施。研究表明:冷轧薄板表面缺陷主要分为常规缺陷和非常规缺陷两大类。常规缺陷的产生与冷轧工艺质量密切相关,而非常规缺陷的形成机理则比较复杂,可能在炼钢工序也可能在轧钢工序形成,需具体情况具体分析。 相似文献

In the so‐called ferritic rolling the finishing is shifted down into the temperature region of ferrite, which enables a production of thinner hot strips (compared to the conventional hot rolling in austenite) with a changed texture development. The present study is focused on the effect of the process parameters of such initial warm rolled hot strips on the texture formation and hence on the deep‐drawing quality of the final cold strips. A special attention is given to the transmission of the hot strip texture to the cold strip. The investigation was carried out on commercial IF‐ and ELC‐steels by a laboratory simulation with the hot deformation simulator Wumsi (rolling simulated by the plane strain compression test). It was possible to optimize cold rolling and subsequent annealing by means of the measurements of the texture development during the ferritic (warm) deformation as well as the parameters of the processing route of such special production of cold strips by means of the calculation of r‐values. If compared with the conventional processing route, a considerable improvement of deep‐drawability with a diminished earing is achievable especially with the IF‐steel. 相似文献
