UKW-500 microcomputer controlled constant temperature sintering resistor

The UKW-1000 microcomputer controlled constant temperature sintering resistance furnace operates at a temperature of 500 ℃, using resistance wires as heating elements and an imported dual microprocessor designed regulator (0.1 level accuracy) with advanced intelligence and performance. It is equipped with SSR enhanced solid-state relays to achieve PID regulation. Widely applicable to industrial and mining enterprises, scientific research and other units for heating plastics, ceramics, composite materials such as sintering, annealing, melting, physical and chemical experiments, and analysis. The furnace of the electric furnace adopts polycrystalline fiber mullite, and the electric heating elements of the air circulation electric furnace are arranged in the airflow channel between the furnace and the furnace wall, uniformly distributed in a single row on the electric heating frame. Each electric heating element is fixed on the electric heating frame with a silicon carbide rib slot bracket (the frame can be pulled out and inserted). The electric furnace uses a motor to drive the fan blades to generate gas movement, which increases the airflow velocity. That is, the number of cycles of airflow in the furnace per minute reaches 0.8-1.0. Due to the heat release of the electric heating elements, the heat dissipation from the furnace to the furnace wall is compensated, further improving the uniformity of the furnace temperature. Ultra fine silicon cotton is tightly packed on the upper, lower, and surrounding furnace walls as insulation material. The furnace door adopts an electric lifting door, which is composed of a reduction motor, a reducer, a shaft, a pulley, a wire rope, a travel switch, etc., so that the furnace door can automatically rise and fall and open and close. The rear end of the furnace top is equipped with an exhaust pipe, and the pipe mouth is equipped with an opening and closing mechanism, which facilitates users to configure the exhaust mechanism to remove harmful gases from the furnace. The furnace base can bear a weight of 500 kg, and the furnace compensation bottom plate is fixed on the track. The workpiece is supported by a rolling platform, making it easy for the workpiece to enter and exit the furnace freely. The entire electric furnace has good sealing and insulation performance. The rotating shaft of the furnace bottom tray is made of heat-resistant stainless steel with a SiC material disc on top. The shaft wheel is driven by the bottom motor to run at a constant speed of 1-5 revolutions per minute, and the SiC pressure bearing capacity can reach 500kg, which means the weight of the workpiece can reach 500kg.
