Abstract: In 2025, electric energy accounts for 30% of industrial terminal energy consumption, and thermal processing is an important part of industrial electricity consumption. Coupled with the factors of technology, equipment and management, the processing cost remains high. In the fierce market competition, energy saving and consumption reduction have become the necessary trend of sustainable development of enterprises. The existing heat treatment process is conservative, the machining allowance is large, the equipment management is backward, and the production plan is discontinuous, which leads to low equipment utilization and serious energy consumption waste. Combined with the present situation, the concept of lean production is introduced into the heat treatment production process, and a low-cost heat treatment production mode is formed through four aspects: reducing machining allowance, equipment transformation, production planning and operation combination.

Key words: gas soft nitriding; carburizing and quenching; induction quenching; lean manufacture

摘要： 2025 年，电能占工业终端能源消费比重计划达到 30%，而热加工又是工业用电的重要 组成部分。受工艺、设备及管理等因素影响，加工成本居高不下，节能降耗成为企业可持续 发展的必然选择。现存的热处理工艺保守、加工余量较大，设备管理落后、生产计划不连续 导致的设备利用率低、能耗浪费严重。结合现状，将精益生产理念导入热处理生产过程中， 通过缩减加工余量、设备改造、生产计划排产及作业组合四个方面进行研究，形成一种低成 本的热处理生产模式。
