Losses in experimental resistance furnaces during the smelting process are a common phenomenon, mainly caused by chemical losses and physical wear of the oxide electrode breaking.
How to repair the equipment in time when there is loss is a problem that users are concerned about, and different causes of loss have different repair methods. The reasons for the chemical loss are: the length of the oxygen gun and the resistance furnace wall angle design, scrap steel and unreasonable oxidation of the oxygen electrode surface of the furnace door oxygen gun cause serious excessive traffic, which will enhance the chemical loss of the equipment.
Wölford Xiaowo offers the following corresponding solutions:
1.Optimize and reduce the direct impact of avoiding oxygen blowing on the electrode.
2. During use, optimize the control of the oxygen gun and adjust the large oxygen flow rate of the oxygen gun.
In addition to the above common chemical losses, electrode crushing is also one of the common loss causes of experimental furnaces, mainly due to two reasons: mechanical failure and electric phase control.
The solutions given for this hazard are:
1. When the temperature is higher than 400 °C, it is not allowed to open the experimental furnace door.
2. The use temperature of the experimental furnace is not allowed to exceed the limit temperature.
3. The temperature of the experimental furnace should not be reduced by more than 50 °C.
4. Avoid excessive force during use, so as not to cause damage to the furnace bottom.
5. The operator should ensure the normal operation of the instrument and electrical control box.
6. When the lining and furnace body of the muffle furnace are damaged, they should be repaired in time to extend the service life of the furnace lining, avoid the damage of the lining, which cannot be repaired, and bring major losses to the user.
The above method can effectively solve the loss problem in the experimental electric furnace work, hoping to help the user.
