气体渗碳是一种先进的工艺,比起固体渗碳、液体渗碳有很多优越性。但它需要特殊的设备,一般多应用Ц型炉,而这种炉子目前很多工厂还浚有,因而影响到这种先进工艺的广泛采用。我厂技术员刘占胜同志和老工人共同研究,设计成功一座螺形火道燃煤井式炉;用它来进行气体渗碳,效果很好。炉子的造价很低(全部包括在内只需1000～1500元);炉子的结构虽 Gas carburizing is an advanced process, compared with solid carburizing, carburizing liquid has many advantages. But it requires special equipment, the general multi-application Ц type furnace, and this furnace is still a lot of factories Jun, and thus affect the widespread use of this advanced technology. Our factory technician Liu Zhansheng comrades and old workers to jointly study and design a successful screw-shaped firebox coal-fired furnace; use it for gas carburizing, the effect is very good. The cost of the stove is very low (all included only 1000 ~ 1500 yuan); Although the structure of the stove
