不同类型的轧机以及同类型而使用条件不同的轧机，吊车轨报价，对所用的轧辊性能要求不尽雷同，吊车轨哪家好，如方坯和板坯初轧机轧辊要具有好的扭转和弯曲强度、韧性、咬入性、抗热裂性和热冲击性以及耐磨性；而热带精轧机架要求轧辊辊面的高硬度、抗压痕、耐磨、抗剥落和耐热裂等性能。
Different types of rolling mill and the same type and the use of different conditi on properties of roll mill， requirements for not identical， such as billet and slab mill roll with good torsional and bending strength， toughness， bite，吊车轨， thermal cracking resistance and thermal shock resistance and abrasion resistance; tropical finishing stand requirements the roller surface hardness， wear resistance， spalling resistance， indentation resistance and thermal cracking performance.
轧辊中大量使用合金元素是在第二次以后，吊车轨生产商，这是轧钢设备朝着大型化、连续化、高速化、自动化发展以及轧材强度提高、变形抗力加大后对轧辊性能提出更高要求的结果。
A large number of alloying elements in the rolls are produced after the Second World War.the result of rolling mill"s large performance， continuous， high-speed and automatic development， as well as the increase of rolling strength and resistance to deformation.
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， it is further affected by various cyclic stresses， including twists， changes， shear forces， contact stresses and thermal stresses.
