乙字钢矫直辊和乙字钢矫直辊系
摘要：
本实用新型一方面提供一种乙字钢矫直辊，包括具有第一矫直界面(10)的上辊(1)和具有第二矫直界面(20)的下辊(2)，第一矫直界面和第二矫直界面为回转面并且组成乙字形孔型。在第一矫直界面和第二矫直界面上，沿着圆周方向设置有用于防止在乙字钢(100)表面产生矫痕的凹进。本实用新型另一方面提供一种乙字钢矫直辊系，第一矫直辊组和第二矫直辊组。第一矫直辊组包括多个上述的上辊，第二矫直辊组包括多个上述的下辊；第一矫直辊组的多个上辊的轴线相互平行，第二矫直辊组的多个下辊的轴线相互平行。本实用新型改进了矫直界面和矫直件的接触位置，因此可以避免矫痕的产生。
摘要（英）：

The utility model provides a z-shaped steel straightening roll which comprises an upper roll (1) comprising a first straightening interface (10), and a lower roll (2) comprising a second straightening interface (20), wherein the first straightening interface and the second straightening interface are rotative surfaces and take on a z-shaped hole pattern, and recesses for preventing straightening marks from generating on the surface of a z-shaped steel (100) are arranged circumferentially on the first straightening interface and the second straightening interface; and the utility model also provides a z-shaped steel straightening roll system, which comprises a first straightening roll group and a second straightening roll group, wherein the first straightening roll group comprises a plurality of the upper rolls, the second straightening roll group comprises a plurality of the lower rolls, axes of the plurality of upper rolls of the first straightening roll group are parallel, and the axes of the plurality of the lower rolls of the second straightening roll group are parallel. According to the z-shaped steel straightening roll, the contact position of the straightening interface and a straightening piece is improved, therefore, the straightening marks are avoided.
