【摘要】 针对旧式离子渗氮炉所存在的问题，在新炉子的研制中作了大量结构改进工作。所研制的双重加热离子渗氮炉可消除工件由油污引起的弧光，提高了工件的温度均匀性，具有省电、节水、生产效率高的特点。用该炉进行气门的离子渗氮，其硬度、表面质量和尺寸精度均能达到产品的技术要求。更多还原

【Abstract】 Authors made much improvement in the construction of new designed ioni triding furnace as compared with the existing imperfectness in the old ionitriding fur nace. The test-manufactured double heating ionitriding furnace has following advan tages:elimination of are induced by oil dirt on workpieces,enhancing temperature unifor mity of workpieces, saving of energy and water consumption, high production efficien cy. The hardness,surface quality and size precision of gas valves treated by above double heating ionitriding furnace can be attained the technical requirements of products.更多还原
