摘要
通过优化可控气氛罩式渗氮炉设计、增加预抽真空系统、选用可编程序控制器及节能材料、减少炉内结构件的热变形等措施,减少了工艺气体消耗量,实现了对炉温及氮势的精确控制、工艺过程的在线动态控制要求,提高了设备运行效率,降低了设备运行成本。
By optimizing the controlled atmosphere bell-type nitriding furnace design, adding pre-vacuum system, selecting programmable logic controller and energy-saving materials can reduce the thermal deformation of the furnace structural parts and save gas consumption, the precise control of temperature and nitrogen potential and process online dynamic control requirements are achieved, operating efficiency of the equipment is improved and operating cost of the equipment reduces.
