摘要

摘要: 为优化影响锆合金管坯外表面粗糙度的磨削工艺参数，提高Zr-4锆合金包壳管的耐腐蚀性能，首先采用中心组合设计方法，在多次抛磨试验结果的基础上，利用Design-Expert 8.0软件建立了与主要磨削工艺参数（砂带线速度、磨削压力、砂带进给速度及管坯旋转速度）具有映射关系的表面粗糙度分析模型；次之，对所建模型进行了优化及可靠性验证；最后通过研究工艺参数间的交互效应对管坯表面粗糙度的影响规律，得到了各工艺参数间的最优组合。试验表明，采用优化后的工艺参数组合进行磨削加工，可将锆合金管坯表面粗糙度有效控制在0.46 μm以下。

Abstract: In order to optimize the grinding parameters which affects the surface roughness and improve the corrosion resistance of Zr-4 alloy cladding tube, a surface roughness model is firstly established by applyingthe central composite design method and Design-Expert 8.0 software, which has a mapping relationship with the main parameters of grinding parameters, including belt speed, grinding pressure, belt feeding speed and tube rotation speed.Secondly, the optimization and reliability verification of the present model are also carried out. Finally, the optimal combination of grinding parameters is obtained by analyzing the effect of the grinding parameters on the surface roughness of tube. The verification experiments show that the surface roughness of the alloy tube can be controlled to be below 0.46 μm effectively by using the optimal combination grinding parameters.
