The experimental power-assisted tube furnace adopts integrated control unit and furnace chamber. The overall double-layer air cooling structure keeps the surface temperature under 60 ℃. The chamber is made of high purity alumina microcrystallite fiber subject to vacuum forming under high temperature. The heating element is resistance wire. The cooling system adopts double-layer air cooling structure, providing a surface temperature ≤60 ℃. The vacuum chamber is made of quartz tubes that run through the whole body. Both ends of the furnace tube are sealed with stainless steel flanges so that the furnace can work in a vacuum or atmosphere environment. The heating elements are parallel to the furnace tube and uniformly distributed outside the furnace tube to effectively guarantee the uniformity of the thermal field. With Yudian AI-3756P touch screen type temperature controller/AI-516P intelligent controller and K-type thermocouple, temperature control through 30 programmable segments with a temperature control precision of ±1 ℃ is realized.
