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 conc***e. When the heat is expanded, it can maintain a better shape.

硬质合金辊环广泛应用于高速线材轧机的精轧机架，以及部分高速线材轧机的预精轧机架和棒材轧机的精轧机架。硬质合金轧辊的优点是硬度高、耐磨性好，单槽轧钢量可以达到高速钢轧辊的两倍。

The cemented carbide roller ring is widely applied to the finishing mill housing of high-speed wire rod mill, as well as the finishing mill for some high speed wire rod mill and the pre finishing mill and bar mill. The biggest advantage of the hard alloy roll is high hardness and good wear resistance, and the amount of single groove rolled steel can reach two times of the high speed steel roll.

19世纪下半叶欧洲炼钢技术的进步要求轧制更大吨位的钢锭，无论是灰铸铁或冷硬铸铁轧辊的强度均已不能满足要求。含碳量为0.4%～0.6%普通铸钢轧辊相应诞生。重型锻压设备的出现更使这种成分的锻造轧辊的强韧性得到进一步提高。

In the second half of the nineteenth Century, the progress of steelmaking technology in Europe requires larger tonnage steel ingots to be rolled. Neither the strength of gray iron or chilled cast iron rolls can meet the requirements. The ordinary cast steel roll with a carbon content of 0.4% to 0.6% is born accordingly. The emergence of he***y forging equipment makes the strength and toughness of the forging roll of this component further improved.

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。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, which can easily lead to instantaneous high temperature, so that the work roll is subjected to strong heat shock, which causes crack, roll, peeling and even scrap. Therefore, 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.
