本文介绍 RJJ—60—9气体渗碳炉改造为气相渗铝专用炉的措施、气相渗铝工艺参数的选择及气相渗铝中应注意的问题。作者提出了采用零件中温入炉(≤700℃)取代原传统工艺低温入炉(≤300℃)的看法,并指出,通过实践证明,中温入炉工艺在保证质量的前提下,可提高生产率4倍。作者还指出,只要严格执行工艺规程,就可以保证质量的稳定性和渗层的均匀性,从而可省去采用扩散处理方法检查渗铝质量的措施。 This article describes the RJJ-60-9 gas carburizing furnace transformed into a special gas-phase aluminizing furnace measures, the choice of gas phase aluminizing process parameters and gas-phase aluminizing should pay attention to. The author put forward the idea of ​​using the temperature of the part into the furnace (≤700 ℃) to replace the low temperature into the furnace (≤300 ℃) of the original traditional process, and pointed out that through practice, the temperature into the furnace process can improve the productivity under the premise of ensuring the quality 4 Times The author also pointed out that as long as the strict implementation of the rules of the process, we can ensure the stability of the quality and the uniformity of the coating, which can eliminate the need for diffusion treatment method to check the quality of aluminized.
