Trolley-type tempering furnace is mainly used for tempering of high chromium cast steel rolls, tempering to eliminate welding stress after repairing the surface of rolls, and tempering for other purposes. It belongs to energy-saving periodic tempering furnace. It adopts microcomputer program process curve automatic temperature control cabinet, and fully automatic and high-precision implementation of the best tempering process curve.

Structure :
Compound lining or full fiber insulation is used in the trolley tempering furnace. The furnace body and the trolley are sealed by themselves to reduce the heat convection loss of the trolley tempering furnace and realize the efficient thermal insulation performance of the trolley tempering furnace.Tempering trolley furnace adopts multi-zone heating, and installed in the top of the furnace stainless steel thermal circulation fan, hot air high-speed circulation, the internal installation of our company’s heat treatment technology center unique design of stainless steel hot air circulation air guide system, temperature uniformity is very high.

Trolley type tempering furnace characteristics:
1. The inside of the furnace is heated by OCr25A /5 strip heating element.

2, The top of the furnace can be used by high pressure centrifugal fan through the air guide inner cover to make the air flow in the furnace reciprocating circulation, so that the furnace temperature is uniform.The eccentric axial flow fan can also be used to make the air flow in the furnace reciprocating circulation to achieve the purpose of furnace temperature uniformity.

3, Tempering furnace lining using aluminum silicate fiber module structure.No heat storage, no gap, adiabatic seal.

4. The door of the furnace is opened up and down by electric hoist.The principle of spring lever is to compress the furnace mouth tightly. Scientific type advanced type.

5. The trolley is equipped with one or more sets of driving wheels and the corresponding passive wheels by the electric cycloid reducer to move on the internal and external double track.

6. Cast steel furnace bottom plate with ZG30Cr18Mmm2SiZn alloy on the bottom heating element.Overlay between blocks to ensure that the oxide scale does not fall into the heating element tank.

7. Adopt PID intelligent zero crossing trigger thyristor. Programming instrument can be connected with 485 communication interface, and computer remote control. Cluster control.With or without paper recorder and paper recorder, over temperature alarm function.
