The furnace body and insulation structure equipment adopt a double-layer shell structure. The furnace body is made through a sealed welding process and undergoes strict air tightness testing. The shell is designed with a special air-cooled guide angle to ensure that all the surface temperatures of the furnace shell are below 60° C, eliminating the risk of high-temperature scalds. The furnace is made of 1400-type high-purity alumina polycrystalline fiber, and the surface is sprayed with a high-temperature alumina coating, and a step sealing structure is used to eliminate the fire problem, ensure a uniform temperature field in the furnace, and extend the length of the constant temperature zone. Filled with fiberboard between the furnace hearth and the furnace shell, with alumina furnace bottom plate, it has excellent thermal insulation performance and low heat loss. 2. The sealed and water-cooled structure furnace door is sealed with a high-temperature silicone gasket, which is tightly fixed by bolts and water-cooled sleeve panels, and has extremely strong sealing properties. The furnace opening adopts stainless steel circulating water jacket design, with φ10mm quick plug-in water inlet and outlet, the cooling water speed can be maintained at 50ml/min, which can quickly reduce the furnace opening temperature, protect the sealing material from high temperature damage, continuously ensure the overall airtightness of the equipment, and adapt to long-term high-temperature continuous operation. 3. The heating structure equipment is equipped with HRE resistance wire,
• +The furnace is heated on the left and right sides + the bottom three sides surrounded by radiation, with uniform heating and no dead angle. The heating element has high temperature strength, excellent oxidation resistance, long service life, high withstand temperature up to 1200 ℃, and can stably adapt to the extreme working conditions of the equipment. 3. The intelligent control system is easy to operate, the process controllable equipment is equipped with an integrated intelligent temperature control system, and the touch screen one-button control mode is adopted, so the operation is simple and easy to understand. Supports 30-stage program heating function. After the user sets the process curve from room temperature to the target temperature, the equipment can run automatically without manual duty. The system has the characteristics of modular design, simple structure, easy maintenance and maintenance. The core adopts thyristor control technology, equipped with PID parameter self-tuning, multi-segment power limiting function, can freely set the constant temperature, insulation curve, not only can achieve automatic accurate temperature control, but also support manual temperature control adjustment, adapt to diversified process requirements. At the same time, it is equipped with an independent airway control system, which consists of core components such as a needle valve, a float flowmeter, and a tetrafluoro pipeline. The intake and exhaust can be precisely adjusted and controlled, and the exhaust pipe with a ball valve on the top can flexibly control the exhaust gas discharge in the furnace and the furnace pressure. IV. Multiple protection, stable and reliable equipment is equipped with a proprietary explosion-proof and protection system as standard, equipped with a mechanical automatic pressure relief device with an adjustable upper limit. When the pressure in the furnace exceeds the standard, it can automatically deflate and stabilize the pressure, eliminating the hidden danger of high pressure. At the same time, the multi-protection functions of over-temperature alarm, disconnection alarm, over-voltage, over-current, and leakage are integrated.
