1.问题的提出 制砖机铰刀是窑厂易损件,我们最早接触该方面的磨损问题是郑州中原窑厂的铰刀磨损。该厂是一大型国营窑厂,设备运转率高,为减少黏土用量,制砖中加入了30％的炉渣,造成铰刀的磨损问题非常突出。该厂最初自行采用碳化钨气焊进行耐磨处理,由于工人操作熟练程度以及其他原因,使用效果很不理想,一副铰刀一般使用10天左右就报废,给维修造成很大困难。 1. The question put forward Brick reamer is a kiln factory wearing parts, the earliest contact with wear problems in this area is the reamer wear Zhongyuan kiln plant in Zhengzhou. The plant is a large state-owned kiln plant, equipment, high operating rate, in order to reduce the amount of clay, bricks added 30% of the slag, resulting in reamer wear problem is very prominent. The plant originally used its own tungsten carbide gas welding wear treatment, due to the proficiency of workers operating and other reasons, the use of results is not satisfactory, a reamer generally used about 10 days to scrap, to repair caused great difficulties.
