1、引言大多数热处理车间的渗碳炉,周末需停炉一天或两天。经常在停炉之前,要将被处理工件全部出空。此时,应向贯通式炉中连续推进空料盘,直至把载有工件的料盘全部运至炉外。再度启动时,炉内渗碳气氛恢复后,即可开始推料。但因传送的都是空料盘,往往要在4至15小时之后,才有渗碳工件出炉。这就意味着贯通式炉每次停炉,都要浪费掉许多全体工人出勤情况下的生产时间。采用断续渗碳工艺,可使贯通式炉或室 1, Introduction Most carburizing furnace heat treatment plant, the weekend need to shut down a day or two days. Often in the shutdown before the work to be empty all the workpieces. In this case, the empty trays should be continuously pushed into the through-type furnace until all the trays carrying the workpieces are transported outside the furnace. Re-start, the carburizing furnace atmosphere recovery, you can start pushing material. However, due to the delivery of empty trays, often 4 to 15 hours after the carburizing workpiece was baked. This means that every cut-off of a through-going furnace consumes a lot of production time when all the workers attend. Using intermittent carburizing process, through the furnace or room
