The beneficial effects of the utility model are: directly flame thrower, flame thrower is arranged in furnace body in the utility model
The flame injection of ejection is on cover, and due to the unique structure of cover, flame can spray to improve in furnace body rapidly around
Temperature, and can avoid direct-injection and cause steel pipe heating uneven on steel pipe；Combustion-supporting gas branch pipe is inserted into the furnace body and is bent through fire
It is connected again with the mixing chamber of the flame thrower between flame injector and cover bottom, obtains the gas in combustion-supporting gas branch pipe
To preheating, to make the more abundant of fuel gas buring, the generation of exhaust gas is reduced；The air inlet of exhaust emission tube is set to furnace body bottom
Portion forces flame thrower to generate moving downward for heat, and it is more uniform to be conducive to heating in furnace body；Protection gas is discharged through exhaust gas
Pipe, cover side pass through, and are fully warmed-up, then are discharged to steel pipe rack surrounding by each protection gas branch pipe, more than effective use
Heat, and prevent protection temperature from spending the low temperature reduction for making steel pipe rack surrounding, improve the annealing effect of steel pipe.
