PARAMÈTRES DU PRODUIT
Description
1300℃ Bell-Jar Furnace
The Bell Jar Furnace is a high-performance electric heating device specifically designed for high-temperature sintering, traitement thermique, degreasing, and the preparation of functional ceramic materials. The equipment adopts a bell-jar-type lifting structure, with the furnace body vertically raised and lowered and the loading platform fixed, facilitating loading and unloading. It is particularly suitable for large-sized workpieces, batch production, and high-temperature precision heat treatment processes.
The equipment has a maximum design temperature of 1300℃ and a long-term operating temperature of up to 1250℃. It employs a four-sided heating structure and an intelligent PID programmable temperature control system, achieving a furnace temperature uniformity of ±5℃ and a temperature control accuracy of ±1℃, meeting stringent temperature control requirements.
Caractéristiques du produit
- Four-sided heating, excellent temperature uniformity
The furnace employs heating elements arranged around the perimeter of the furnace chamber, forming a three-dimensional heating field. Temperature uniformity within the effective temperature zone is ±5℃, with a temperature control accuracy of ±1℃, suitable for batch sintering and heat treatment of large-volume products. The heating elements use U-shaped silicon carbide rods of equal diameter, using high-purity α-SiC as the main raw material, resulting in rapid heating, haute efficacité thermique, longue durée de vie, and resistance to deformation at high temperatures, reaching temperatures up to 1500℃.
- Dual-cylinder hydraulic lifting, emergency protection against power failure
The furnace body is lifted using a dual-cylinder hydraulic system. The hydraulic system includes a manual descent button in case of power failure. A mechanical locking safety buckle prevents descent during lifting, ensuring operational safety.
- Multi-layer tapered step soft seal, excellent sealing performance
The upper furnace body opens vertically with lifting. The charging platform and furnace opening utilize a 3-4 layer tapered step soft seal structure. Elastic high-temperature sealing strips are arranged on the steps to effectively absorb the thermal expansion of the refractory materials at the furnace opening and charging platform. A sealing sand structure is installed around the charging platform, providing double sealing protection.
- Composite Refractory Material for Charging Platform: Balancing Insulation and Load-Bearing Capacity
The charging platform is constructed from a combination of vacuum-formed high-purity alumina lightweight material and high-purity alumina hollow spherical plates, ensuring both insulation and load-bearing performance. The furnace refractory material is also made of vacuum-formed high-purity alumina lightweight material, which has low heat storage capacity, is resistant to rapid heating and cooling, and achieves energy savings of over 80% compared to older electric furnaces.
- 7-inch Touchscreen for Real-Time Reading and Writing
The 7-inch touchscreen can read and write stored parameters such as temperature, temperature range number, time period, temps restant, output power percentage, tension, and current in real time, providing intuitive and convenient operation.
