渗碳以及随后的热处理,它的周期一般都很长。所以,改进渗碳工艺,提高渗碳速度,进而缩短渗碳和热处理的生产周期,是一項具有实际意义的工作。現在把我們在提高气体渗碳速度方面所获得的一些经驗,介紹如下,供参考。一、适当提高渗碳温度由于受設备的限制,我厂Ц—25气体渗碳爐的最高使用温度只达950℃。在不影响設备使用寿命的条件下,我們将渗碳温度由原
Carburizing and subsequent heat treatment, the cycle is usually very long. Therefore, to improve the carburizing process, increase the carburizing speed, and then shorten the carburizing and heat treatment cycle, is a practical work. Let us now introduce some of the experiences we have gained in increasing the rate of gas carburizing as follows. First, the appropriate increase in carburizing temperature Due to the equipment constraints, I plant Ц-25 gas carburizing furnace maximum temperature of only 950 ℃. Without affecting the service life of equipment, we will carburizing temperature from the original
