Wide application of trolley resistance furnace in foundry industry

Large high temperature trolley type resistance furnace belongs to periodic operation type resistance furnace, which is mainly used to heat rolls or other alloy steel parts below 1200 ℃.

characteristic:

1. The trolley walking and furnace door lifting are all electric, with low labor intensity;

2. The new composite lining has less heat storage and uniform heating. Compared with the old products, energy saving is more than 20%;

3. Electric heating elements are set on the door and back wall of large trolley furnace, and the furnace temperature uniformity is better than the value specified in international military standards and maritime standards;

4. A special sealing structure is adopted between the furnace door and the panel, so that the heat loss and atmospheric loss are small and the furnace gas is stable;

5. According to the different requirements of users, the circulating fan and guide air system can be added;

6. The trolley can be made into hydraulic or mechanical tilting type, which is easy to operate;

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

8. The automatic sealing device of trolley and furnace body is novel, reasonable in design, practical and safe;

9. Effective sealing measures, less oxidation device and impermeability and brittleness resistant electric heating elements can ensure less oxidation.
