crane生产厂家-吉林crane-圣霖国际【开拓创新】

不同类型的轧机以及同类型而使用条件不同的轧机，对所用的轧辊性能要求不尽雷同，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， 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.

生产长材产品的轧机种类繁多，因此，crane报价，轧机类型的选择、布局，轧辊材质的选择、轧辊尺寸的确定，选择范围也非常广。同时，crane生产厂家，不同的轧机所选择的轧辊也是不相同的，需要根据生产要求选择轧辊。

There are a wide variety of rolling mills to produce long timber products. Therefore， the selection and layout of the type of rolling mill， the selection of the material of the roll and the determination of the size of the roll are also very wide. At the same time， the rolls chosen by rolling mills are also the roller should be selected according to the production requirements.

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，吉林crane， 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，crane厂家， 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.
