Application of trolley type resistance furnace: large high temperature trolley type resistance furnace belongs to periodic operation type resistance furnace, mainly used for heating roll or other alloy steel parts below 1200 ℃.

Characteristics of trolley type resistance furnace:

1. Trolley travel and furnace door lifting are electric, with low labor intensity;

2. The furnace lining adopts a new type of composite furnace lining, with less heat storage and even heating. Compared with the old products, the energy saving is more than 20%.

3. The electric heating elements are set in the door and back wall of the large-scale trolley furnace, and the furnace temperature uniformity is better than the international military standard and navigation standard.

4. Special sealing structure is adopted between furnace door and panel, with less heat loss and atmosphere loss and stable furnace gas;

5. According to different requirements of users, add circulating fan and air guide system;

6. The trolley can be made of hydraulic or mechanical tilting type, which is convenient for operation;

7. 1200 ℃ furnace adopts special high temperature and high resistance electric heating alloy as heating element, with long service life;

8. The automatic sealing device of trolley and furnace body is novel, reasonably designed, practical and safe;

9. Effective sealing measures, less oxidation device and anti permeability and anti embrittlement electric heating element can ensure less oxidation.

Technical parameters of trolley type resistance furnace:
