摘要
采用二次回归正交实验设计方法对此种冷作模具钢的热处理工艺参数进行了优化设计,从而得到了能够描述淬火温度和回火温度对该冷作模具钢硬度影响规律的数学模型。并且此种冷作模具钢还具有淬火温度低、热应力小、变形开裂倾向小、氧化脱碳少等特点。通过磨损试验比较,此钢的耐磨性略高于传统的高速钢W18Cr4V。
By using the orthogonal experimental method of quadratic treatment parameters for high carbon and high-alloy cold-working die steel were optimized. A mathematic model, which can describe the law of quenching and tempering temperature＇s influence on the hardness of die steel was obtained. This kind of cold-workingdie steel has some characters such as low quenching temperature and thermal stress, low tendency to deforming and cracking, and low degree of oxidation and decarbonization, Through wearing test, this kind of steel is proved to have better wear-resisting property than typical highspeed steel W18Cr4V,
