摘要
本文以压球机用9Cr2Mo钢辊皮为研究对象,探讨了双液淬火方式对辊皮表面硬度和热处理变形的影响,确定了辊皮双液淬火工艺参数。结果表明,采用双液淬火方式处理,辊皮外表面形成了中间硬度高、边部硬度低的硬度梯度分布,辊皮的热处理变形减小,使用寿命得到了明显的提高。
The influence of dual liquid quenching method on the surface hardness and heat treatment deformation of 9Cr2Mo steel roller sheet are investigated in this paper.The process parameters of dual liquid quenching of roller sheet are determined.The results show that hardness gradient distribution with high hardness in the middle and low hardness in the edge is formed on the outer surface of roller sheet by dual liquid quenching,the heat treatment distortion is reduced,and the service life is obviously improved.
