Abstract:
     The invention discribes a technology which can be operated continuously. The heating temperature is 900 deg.C -10 deg.C and the quenching temperature is 870 deg.C - 10 deg.C. The pressure of spout is 1.5-3kg/cm2. The direction of the spout is at the angle of 30 deg. to the moving direction of the work-piece. The workpiece moves forwad at a velocity of 1.3m/min. and rotates by itself at an angulor velocity of 2.5rpm. This technology improves the homogeneity of the products and lengthens the service life of the products. It is easy to operate and control. The device for realizing the technology is compact, occupies an area equivalent to 10% of that of a resistance stove, and the power consumption is only half of the latter.
