摘　　要：ZG0Cr14Ni5Mo2Cu不锈钢铸件在铸造、热处理及加工等过程中极易产生变形,且因铸件结构限制、合金强度较高等因素影响,ZG0Cr14Ni5Mo2Cu不锈钢铸件冷态校正难度极大。本试验通过对比ZG0Cr14Ni5Mo2Cu不锈钢铸件在不同高温条件下校正效果及性能变化,开展不锈钢铸件加热校正工艺研究。研究表明,ZG0Cr14Ni5Mo2Cu不锈钢铸件热校正温度不应低于650℃,且不应高于850℃,在此温度区间进行热校正不影响铸件力学性能。ZG0 Cr14 Ni5 Mo2 Cu stainless steel casting deformation easily occurs during casting,heat treatment and machining.Cold correction of ZG0 Cr14 Ni5 Mo2 Cu stainless steel castings is extremely difficult.By comparing the correction effect and performance change of stainless steel castings under different high temperature conditions,the heating correction technique of ZG0 Cr14 Ni5 Mo2 Cu stainless steel castings was studied.The results show that the thermal correction temperature of ZG0 Cr14 Ni5 Mo2 Cu stainless steel castings is at the temperature range between 650℃and 850℃,which will ensure that the mechanical properties of the castings are not affected.
