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.
