摘　　要：对基于响应曲面法的大型轧辊磨削工艺参数优化进行研究,针对大型轧辊磨削过程中存在轧辊表面粗糙度控制稳定性与一致性差等问题,采用响应曲面法对轧辊磨削工艺参数进行优化。通过使用碳化硅砂轮对无限冷硬铸铁轧辊进行磨削试验,以磨削加工后的表面粗糙度Ra为优化目标,利用响应曲面法分析轧辊转速、磨削深度、拖板速度和砂轮速度对磨削表面质量的影响规律,并建立相应的多项式模型。通过该模型得到的最优工艺参数组合为:轧辊转速26r/min,磨削深度10.3μm,拖板速度1.545m/min,砂轮速度27.5m/s,磨削后轧辊的表面粗糙度为0.335μm,表面质量显著提升。In this paper,based on response surface method,the optimization of grinding process parameter for large roll is studied.Aiming at the problem of poor stability and consistency of roll surface roughness control in the grinding process of large rolls,the response surface method is used to optimize the grinding process parameters of rolls.The grinding experiment of infinite cold cast iron roll is carried out by using silicon carbide grinding wheel.With the surface roughness as the optimization target,the influence law of roller speed,grinding depth,drag plate speed and wheel speed on the surface quality after grinding is analyzed by response surface method.Finally,the corresponding polynomial model is established.The optimum process parameters obtained by the model are as follows:roller rotation speed 26r/min,grinding depth 10.3μm,towing plate speed 1.545mm/min,grinding wheel speed 27.5m/s,surface roughness of the grinding roll 0.335μm,by which the surface quality can be significantly improved.
