化学热处理的滴液控制都认为是极重要的环节,滴量的多少直接影响到热处理产品的质量。但目前滴液控制基本上是均采用人工操作,眼睛计数,劳动强度大,并且不正确。也有单位采用流量计,但是小流量液体流量计的精度差维护麻烦,故仍未能普及推广使用。为此我们在75kw渗碳炉的滴注器上进行了改造,并配上电子计数器,数码管显示,制成了滴量 Chemical heat treatment of the drop control are considered to be very important part of the amount of the amount directly affects the quality of heat treatment products. At present, however, drop control basically uses manual operation, eye counting, labor intensity, and is not correct. Some units also use flowmeters, but the poor accuracy of small flow liquid flowmeter maintenance trouble, it is still not widely used to promote the use. To this end, we carried out remodeling on a 75kw carburizing drip chamber and equipped with an electronic counter and digital display to make a drop volume
