北京永定机械厂在制造拖拉机任务中,牙轮等渗碳件很多。该厂原为修理厂,热处理的设备不多,也没有气体渗碳炉,都是用固体渗碳的。要在“十一”出一批拖拉机,任务很繁重,特别是渗碳很慢,这就成为完成任务的关键问题。他们提出用高频气体渗碳,经苦战二天已试验成功,并投入生产。设备系利用ЛΓП3-30型高频电炉酸性熔炼坩埚略加改装,作为高频气体渗碳设备。渗碳温度为1000～1050℃。在连续生产高温装炉条件下,经30分钟后即
Beijing Yongding Machinery Factory in the manufacture of tractor tasks, a lot of round of isotope carburizing. The factory was originally a repair shop, heat treatment equipment is not much, there is no gas carburizing furnace, are solid carburizing. To be in “eleven” out of a group of tractors, the task is very heavy, especially carburizing is very slow, which has become the key issue to complete the task. They proposed using high-frequency gas carburizing, after two days of hard work has been successfully tested and put into production. Equipment is the use of ЛΓП3-30 high-frequency electric smelting crucible slightly modified as a high-frequency gas carburizing equipment. Carburizing temperature 1000 ~ 1050 ℃. In a continuous production of high temperature loading conditions, after 30 minutes
