在传统的推杆式连续气体渗碳炉内完成增压或扩散工艺尚未解决,本文介绍一种能提高生产能力的气体控制系统。0 引言 为了达到最短的渗碳时间,方法应能把渗碳初期高碳势和渗碳末期低碳势结合起来。在浴炉内,很容易从改变最后扩散期的高碳势来达到这种结合。而在连续推杆式炉内,不同区之间没有密封门,要实现增压或扩散渗碳就不那么简单。 本文阐述的是研制一种在连续炉内快速渗碳的气体系统和控制系统,并要提高渗碳过程的质量。 为了有效渗碳,碳势必须在每一个区内局部控
In the traditional push rod continuous carburizing gas furnace to complete the booster or diffusion process has not yet been resolved, this article describes a gas production control system to improve productivity. 0 Introduction In order to achieve the shortest carburizing time, the method should be able to combine the high carbon potential in the early stage of carburizing and the low carbon potential in the last stage of carburizing. In bath ovens, this combination can easily be achieved by altering the high-carbon potential of the last diffusion period. In a continuous pusher furnace, there is no sealed door between different zones, so it is not that simple to achieve supercharging or diffusion carburizing. This article describes the development of a rapid carburizing in a continuous furnace gas system and control system, and to improve the quality of the carburizing process. In order to carburize effectively, carbon potential must be locally controlled within each zone
