Temperature Control Accuracy: +1 Temperature
Cavity Material: Ceramic Fiber Insulation System
Heating element: resistance wire (below 1200 C).
Silicon carbide rod or gas/fuel heating (up to 1200 C)
Description of Industrial Vacuum Box Heat Treatment Furnace
Box ovens can be designed as vertical lifting doors or swing doors, allowing products of various sizes to be placed in the oven, and can be customized to meet many processing requirements. Multi-zone heating technology can be integrated to maintain excellent temperature uniformity of parts and achieve heating and cooling curves.
Box structure: All of them adopt ceramic fiber insulation system. Alos can be combined with the special design of atmospheric protection.
Heating method: Electric, direct combustion or indirect gas is provided according to specific processing requirements.
Furnce Gate: Frame made of steel plate. The two types of doors are vertical lifting and swinging.
Heating efficiency: Special design of door seal, built-in heating wire to ensure excellent sealing performance and uniform furnace temperature.
Protection: Equipped with various interlocking protection devices, can prevent malfunctions and accidents caused by misoperation.
Characteristic of steel hardening industrial box furnace:
1). The use of ceramic fibers greatly shortens the start-up heating time and saves energy up to 20% - 30%.
2). Special design of the door and drum seal, built-in heating wire to ensure good sealing of the door, furnace temperature uniformity.
3). Double thermocouple control: one thermocouple is used to test furnace temperature, and the other is used for overheating protection.
4). The furnace body is equipped with interlocking protection device, which can prevent malfunctions and accidents caused by misoperation.
5). Intelligent digital temperature control system is adopted, with clear reading, convenient adjustment, high temperature control accuracy, simple structure, safety and reliability.
