我厂产品制造中金属切削工作量占70％,对刀具要求数量多,质量高。过去我厂高速钢刀具经1270℃～1280℃淬火,560℃二次回火后,采用液体氰化处理。由于工艺复杂,盐浴成份波动较大,质量不稳定,同时氰化处理时劳动条件差,有剧毒、污染环境。为了改进这一情况,对高速钢刀具试验了气体软氮化和氧氮化处理,使刀具耐磨性在原
I plant manufacturing metal cutting work accounted for 70% of the number of tools required, high quality. In the past I plant high-speed steel tools by 1270 ℃ ~ 1280 ℃ quenching, 560 ℃ secondary tempering, the use of liquid cyanide treatment. Due to the complexity of the process, the components of the salt bath fluctuate greatly, the quality is unstable, and at the same time, the working conditions in the cyanidation are poor, and are highly toxic and pollute the environment. In order to improve this situation, the test of high-speed steel cutter gas nitrocarburizing and nitriding treatment, the tool wear resistance in the original
