Mainly used for mud core drying and normalizing, annealing and quenching of metal components. The natural gas casting annealing furnace skeleton is welded from various types of steel. The outer frame uses channel steel as the main beam, the surrounding plate uses cold thin plate, the trolley uses channel steel as the main beam, and the bottom plate and front and rear plates use medium plates.
Transmission part of the annealing furnace for natural gas casting: The trolley transmission uses a motor and a reducer to drive a group of front-end driving wheels through a chain. Furnace door transmission is a combination of worm gear reducer and electric motor. Gas casting annealing furnace sealing: The trolley and furnace body are sealed with a labyrinth structure, and there is an automatic sand sealing knife sealing device on the side of the trolley. The furnace door is sealed with a roller-type compaction and a spring-loaded automatic mechanism. The furnace body part is made of refractory brick structure to ensure the tightness of the furnace. High-aluminum bricks are used for the pressure-resistant part of the trolley, and thermal insulation bricks are added to the lower part for thermal insulation. Combustion system of natural gas casting annealing furnace: Several burners are installed on both sides of the oil furnace, and the heat flow is circulated in the furnace to ensure the uniformity of the furnace temperature. Can choose automatic type and semi-automatic type according to need. Annealing furnace smoke exhaust preheating device: A smoke exhaust preheating device is installed at the upper end of the furnace. When the flue gas in the furnace passes through the preheater, it is sent to the cold air by the fan for preheating, and then sent to the burner nozzle to assist combustion , And a manual disc valve is installed at the outlet, which can adjust the pressure in the furnace.
