|Maximum power approx.||20KW|
|Delivery||1 door plug, 1 crucible tongs, 1 pair of high temperature gloves, and 1 hex wrench for the shell.|
|special requirements||1. Two temperature zones to control temperature
2. Install a temperature measuring thermocouple on the back wall, and realize data display and recording
3. High box, electric control placed on the side
|Warranty|| ● 12 months warranty (except for consumable parts such as silicon molybdenum rods, silicon carbide rods and man-made damage), lifetime warranty, and free technical guidance installation and equipment commissioning services. After the warranty expires, renewal services are provided.
● General faults are resolved within 24 hours, and major faults are resolved within 72 hours. In special circumstances, technicians can go to the scene to deal with problems.
|usage notice||● The temperature of the electric furnace should be slowly cooled down.
● It is forbidden to heat flammable and explosive substances and pass flammable and explosive gases.
● After the electric furnace is used, small cracks will occur on the surface of the furnace lining. This is a normal phenomenon and does not affect the service life of the electric furnace.
● Before the electric furnace is heated, the fire block of the furnace door must be placed in the furnace frame.
