摘　　要：通过L9(3^4)正交设计试验表进行正交试验,研究LN17模具钢预硬化热处理最优工艺参数。结果表明,采用1,020℃淬火、630℃回火4h预硬化处理,硬度值为30.2~30.7HRC,达到技术标准硬度28-32HRC的中值。A study of Pre-hardening heat treatment parameter for LN 17 was conducted by orthogonal test of L9(3^4). Results showed that hardness of 30.2~30.7HRC were made by a optimum process of quenching at 1,020℃, tempering at 630℃for 4h.
