Box type resistance furnace is a common form of electric furnace, which can be divided into vertical, horizontal, split, and integrated types. The temperature range is divided into below 1200 degrees, 1400 degrees, 1600 degrees, 1700 degrees, 1800 degrees, etc. Resistance wires, silicon carbon rods, and silicon molybdenum rods are used as heating elements, which can be selected according to needs. In addition to heating in air, box type electric furnaces also have gas permeable and sealed vacuum electric furnaces, with various forms. Widely used in the production and experimentation of ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new material development, special materials, building materials and other fields.
Structural characteristics of box type resistance furnace:
1. The appearance is treated with high temperature resistant and corrosion-resistant paint.
2. The console adopts an intelligent PID digital controller with good stability and high accuracy, equipped with an ammeter and a novel structure.
3. The furnace door is thickened and reinforced to prevent deformation.
4. The furnace lining is made of insulation cotton, which has good insulation effect.
5. The furnace temperature real-time detection function (displays the actual furnace temperature even without heating, making it easy to observe the furnace temperature situation at any time).
6. The wiring is simple, the diagram is clear, and the operation is convenient.
7. Equipped with overload protection and short circuit protection.
8. The furnace shell is made of welded steel plates with folded edges, and the workshop is a furnace made of refractory materials. The heating element is placed inside, and insulation materials are used to build between the furnace and the shell.
