What should I pay attention to when using the box type resistance furnace?
1. To ensure safe use, ground wire must be installed and grounded well.
2. When the box type resistance furnace is heated, the furnace shell will also become hot. The working environment requires no flammable and easy items and corrosive gas, and it is easy to dissipate heat.
3. After the box type resistance furnace is used, the power should be cut off to make it cool naturally. The furnace door can only be opened when the temperature is lowered below 200 °C. The furnace door should not be opened immediately, so as to avoid the furnace being suddenly crushed by cold. If it is urgent, you can open a small slit to make it cool down.
4. The refractory material in the new furnace contains a certain amount of water. When it is used for a long time or after being deactivated for a long time, it should be oven first. The temperature is gradually increased from 200 to 600 °C for about 4-5 hours to prevent the temperature of the furnace due to moisture. Abrupt changes and rupture; the first use of baking can also cause the heating element to form an oxide layer.
5. When using, the furnace temperature should not exceed the temperature of the Zui blast furnace, so as not to burn the electric heating components, and do not work longer than the rated temperature for a long time.
6, pay attention to safety, to prevent burns.
7. After several cycles of heating, the insulation material of the furnace may crack. These cracks are caused by thermal expansion and have no effect on the quality of the furnace.
8. Always check the wiring head and the operation of the pointer. Check the button at least once a month to clean the furnace and clean the furnace without power.
Second, extend the life of the furnace wire , do not work in the high temperature state for a long time,
2, correct preheating,
3. When the digital display is controlled, the output voltage is appropriately lowered, the heating rate is slowed down, and the high-quality electric furnace wire is selected.
