Control characteristics |
Modular structure of control system, long-life design of key components of equipment, simple and reliable process, good stability and high precision. |
|
Air cooling system |
The fan impeller is directly installed at the bottom of the double-layer furnace shell and assembled with the control system. When the furnace is heated, air cooling can reduce the surface temperature of the furnace shell and protect the heat dissipation of electrical appliances, make personnel operation safer and improve efficiency. |
|
Refractory material |
The furnace lining adopts imported high-purity alumina fiber, vacuum formed fiber material and light hollow aluminum oxide plate. It has high service temperature, small heat storage capacity, rapid heat and cold resistance, no crack, no slag falling and good thermal insulation performance (the energy-saving effect is more than 80% of that of the old electric furnace). Double furnace structure, which not only has fast heating speed, but also has the characteristics of strong and durable, and no collapse in long-term use. |
|
Thermal insulation material |
Imported alumina multi fiber insulation material, the insulation layer is 120mm. |
|
Shell |
It is welded by steel plate and profile, and the shell is equipped with detachable protective plate, which adopts electrostatic spraying and paint baking. Fine workmanship and elegant appearance. |
|
Furnace structure |
Double layer furnace shell structure, air cooling circulation, reduce the shell temperature, and the shell surface temperature is less than 55ºC. The surface of the inner furnace is coated with high-temperature alumina coating, which can improve the heating efficiency of the equipment and prolong the service life of the instrument. The opening between the furnace door and the furnace body is secured by a stainless steel lock ring connected by hinges. |
|
Furnace structure feature |
The furnace body is heated on all four sides, including heating elements, thermocouples, and controllers. Part of the furnace materials are composed of ceramic fiber materials and hollow spherical alumina. The upper part of the furnace is a mesh furnace cover, and the carbon steel plate on the side of the furnace body is 3mm. In order to prevent heat loss in the form of thermal radiation, double furnace door seals are used. |
|
