AI Technical Summary
After prolonged use, existing furnace lifting doors may develop gaps due to friction, leading to heat and gas leakage and affecting the furnace's performance.
The manual furnace door automatic lifting mechanism uses a motor to drive the movable bolt and threaded rod to lift the closed furnace door. It is stable by combining the limit rail and limit strip, and the electric telescopic rod pushes the mounting frame and the closed furnace door to extend and retract in front of the furnace opening. The mating strip and mating groove are used to achieve a good seal.
This ensures that the sealed furnace door remains stable during long-term use, preventing heat and gas leakage and ensuring the normal operation of the furnace.
