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.
轧辊是轧机的核心部件，轧辊的使用涉及轧机使用时的类型选择、轧辊的准备、在轧制过程中的维修和周期性修整，而这些都全是影响轧机生产率、产品质量和生产经济性的因素。
Roll is the core part of the rolling mill. The use of the roll involves the type selection of the rolling mill，sleeper报价， the preparation of the roll， the maintenance and the periodic dressing during the rolling process，sleeper厂家， all of which are all factors that affect the productivity of the rolling mill， the quality of the product and the production economy.
轧辊在制作和运用前的预备工序中会发生剩余应力和热应力。运用时又进一步遭到了各种周期应力的效果，包含有曲折、改变、剪力、接触应力和热应力等。
Residual stresses and thermal stresses will occur in the preparatory process before making and applying rolls. When applied，sleeper， it is further affected by various cyclic stresses， including twists， changes， shear forces， contact stresses and thermal stresses.
