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，朝阳sleeper，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 conditi*** of the roller and choose the right and economical roller material.
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，sleeper厂家，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.
整体轧辊是相对于复合轧辊而言的，整体轧辊的辊身外层与心部以及辊颈采用单一材质铸造或锻造而成，辊身外层和辊颈不同的***、性能通过铸造或锻造工艺以及热处理工艺过程来控制和调整。
The whole roll is compared to the roll. The outer layer of the whole roll is made of a single material or forging with a single material. The structure and performance of the roll are and adjusted by the casting or forging process and the heat treatment process.
