渗碳炉所用的滴量器是渗碳的主要工具,是相当控制渗碳剂流入炉中多少的小阀门。特大型轴承渗炭是深层渗炭,而且渗碳的设备都是很大的井式炉(1.[DII-250),所以渗碳剂(煤油或苯)的耗量较大,滴数较多,操作者在控制滴量器时,当滴数超过200滴以后,用现有的滴量器,就不易控制准确,误差约达到土15滴/分,当工艺要求滴数280滴/分以上时,操作者几乎无法数清,滴量器滴数控制不准确,渗碳速度就会受到影响,工件的硬化层粗大碳化物的增长情况不能很好地摸索与掌握,造成工艺与实
The carbuncher used in the titer is the main tool for carburizing, is a considerable control of how much carburizing inflow furnace small valve. Large bearings infiltration charcoal is deep carburizing, carburizing equipment and are great pit furnace (1. [DII-250), so the carburizing agent (kerosene or benzene) greater consumption, more than the number of drops When the operator controls the dropper, when the number of drops exceeds 200 drops, it is difficult to control accurately with the existing drop gauge. The error is about 15 drops per minute. When the process requires a drop of 280 drops per minute , The operator almost can not count the number of drops drip drip control is not accurate, carburizing speed will be affected, the hardening of the workpiece thick carbide growth can not be very good to explore and grasp, resulting in technology and real
