Oil-immersed resistance tempering furnace. Used in our plant for three years and achieved good results. However, revolutionary heat-treatment workers, cadres and technicians did not satisfy the achievements they had made and in accordance with Chairman Mao, the great leader, “mankind has to sum up his experience constantly, discover something, invent something, create something, and make progress.” Teach, in the popularization, in-depth, lasting batch of approved Lin hole, carefully summed up the oil-immersed resistance furnace back to the use of experience and analysis of the heating resistance of the wire itself is not high temperature characteristics of this bold test A wire instead of resistance wire heating element to do the “oil-immersed wire resistance furnace.”
