1. Brief Induction
The gas fired bogie hearth furnace is mainly used for heat treatment of metal parts.
The furnace skeleton is welded by various types of steel, the outer frame is made of channel steel as the main beam, the coaming plate is made of cold sheet, the trolley is made of channel steel as the main beam, and the bottom plate and the front and rear plates are made of middle plate.
Transmission part: The trolley transmission adopts a motor and a reducer to drive a set of driving wheels at the front end through a chain. The furnace door drive adopts a combination of a worm gear reducer and a motor to lift it electrically.
Sealing: The trolley and the furnace body are sealed with a labyrinth structure, and there is an automatic sand sealing knife sealing device on the trolley side. The furnace door is sealed by rolling channel pressing and spring pressing automatic mechanism. The furnace body part adopts high-quality refractory brick structure to ensure the tightness of the furnace. The pressure-resistant part of the trolley is built with high-alumina bricks, and thermal insulation bricks are added to the lower part.
Combustion system: Several burners are installed on both sides of the oil furnace, and the heat flow reciprocates in the furnace to ensure the uniformity of furnace temperature.
