sleeper 圣霖国际【精益求精】 sleeper谁家好

冷轧辊在工作过程中要承受很大的轧制应力，加上轧件的焊缝、夹杂、边裂等问题，容易导致瞬间高温，使工作辊受到强烈热冲击，造成裂纹、粘辊、剥落甚至报废。因此，冷轧辊要有抵抗因弯曲应力、扭转应力、剪切应力引起的开裂和剥落的能力，同时也要有高的耐磨性。

Cold roll must bear a lot of rolling stress in the working process， add the weld， inclusion and edge crack of the rolled piece，sleeper谁家好， which can easily lead to instantaneous high temperature， so that the work roll is subjected to strong heat shock，sleeper厂， which causes crack，sleeper哪家好， roll， peeling and even scrap. Therefore，sleeper， the cold roller must resist the ability of cracking and spalling caused by bending stress， torsional stress and shearing stress， and also has high wear resistance.

轧辊是轧机的重要部件，按照轧机类型可分为领带轧机轧辊、型钢轮机扎辊和钢管轧机轧辊三大类。

板带轧机轧辊的辊身呈圆柱形，热乾板带轧辊的辊身微凹，当受热膨胀时，可保持较好的扳形。

Roll is an important part of the rolling mill. According to the type of rolling mill， it can be divided into three types: the tie mill roll， the type steel turbine ligation roll and the steel tube rolling mill roll.

The roll body of a strip rolling mill is cylindrical， and the roll body of the hot dry plate is slightly concave. When the heat is expanded， it can maintain a better shape.

弄清轧辊的使用条件以及在同类型轧机中所用轧辊的失效方式，了解当前各种轧辊材质的性能和制造工艺，才能较正确地制定该轧机用辊的技术条件和选用合适而经济的轧辊材质。

We must know clearly the condition of the roller and the failure way of the roll used in the same type of rolling mill， and understand the performance and manufacturing technology of all kinds of roller material at present， so that we can correctly formulate the technical conditions of the roller and choose the right and economical roller material.
