What are the characteristics of the trolley furnace

trolley furnace is mainly used for tempering high chromium cast steel rolls, and tempering to eliminate welding stress after repairing the roll surface. It is a temperature-saving furnace that runs regularly. The use of a microcomputer process curve automatic temperature control cabinet can automatically and accurately execute the temperature saving process curve.

The trolley furnace adopts multi-zone heating, and the furnace top is equipped with a stainless steel thermal circulation fan to make the hot air circulate at a high speed. The inside is equipped with a stainless steel air guide system specially designed by our company’s heat treatment technology center, which has high temperature uniformity.

1. The inside of the trolley furnace is heated by a belt-shaped heating element.

2. The high-pressure centrifugal fan can be used on the top of the furnace to circulate the airflow in the furnace back and forth through the inner cover of the air deflector to make the furnace temperature uniform. The eccentric axial fan can also be used to rotate the air in the furnace to achieve the goal of uniform temperature in the furnace.

3. The inner lining of the trolley furnace adopts aluminum silicate fiber module structure. No heat storage, no gap, heat preservation and sealing.

4. The oven door is opened and closed by an electric hoist. According to the principle of spring rod, the furnace mouth is pressurized and sealed by its own weight.

5. The bottom plate of the trolley furnace is covered on the bottom heating element. The upper openings between the blocks are stacked together to ensure that the scale does not fall into the groove of the heating element.

6. The high temperature trolley furnace uses PID intelligent zero-cross contact thyristors. The programmer can remotely control through the 485 communication interface with the computer. Cluster control. There is no paper recorder, there is a paper recorder and an overheating alarm function.
