过去我厂氮化处理使用氮化箱,在30千瓦箱式电炉中加热。存在耗电多,时间长,污染环境、操作不方便等缺点。并式气体渗氮炉也存在一些不足之处。针对这些问题,我们在1980年设计制造了一台气体渗氮炉,在结构上做了一些改进。几年的使用证明,这些结构具有省电、操作方便、测温准确、改善工作环境、渗氮速度提高1～3倍以上等优良性能。下面简单介绍一下炉子结构。 1.炉膛与保温材料的选用气体渗氮炉工作温度一般在500～650℃范围内,为提高炉子的升温速度,降低能耗,制造简
In the past, our factory used nitriding nitriding box, heated in a 30 kilowatt box electric furnace. There are many shortcomings of power consumption, long time, pollute the environment, inconvenient operation. And gas nitriding furnace there are some shortcomings. In response to these problems, we designed and manufactured a gas nitriding furnace in 1980, and made some structural improvements. Years of use proved that these structures have the advantages of power saving, easy operation, accurate temperature measurement, improved working environment, nitriding speed increased by 1 to 3 times and above. Here’s a brief introduction to the furnace structure. 1. Furnace and insulation material selection Gas nitriding furnace operating temperature is generally in the range of 500 ~ 650 ℃, in order to increase the furnace heating rate, reduce energy consumption, manufacturing Jane
