Abstract
It the utility model is related to a kind of Equipment for Heating Processing, more particularly to a kind of combustion gas annealing oven protective atmosphere heating system.Including protective atmosphere generating means, annealing furnace, burning burner is provided with by protecting feed channel to be connected between the protective atmosphere generating means and annealing furnace, in annealing furnace, burning burner is connected with exhaust piping；The protection feed channel is provided with protective atmosphere part flow arrangement；The protection feed channel is out of exhaust piping by playing a part of heated protective gas.The waste gas of high temperature is recycled, heated protective atmosphere.Low-temperature protection atmosphere is reduced to the heat consumption in annealing furnace.By technological transformation, reduce 10% gas consumption.Production cost greatly has been saved, has improved product quality.
Description
Technical field
It the utility model is related to a kind of Equipment for Heating Processing, more particularly to a kind of combustion gas annealing oven protective atmosphere heating system.
Background technology
To prevent steel from aoxidizing in the lehr, protective atmosphere can be injected into stove.Protective atmosphere is normal temperature or is slightly below
The gas of normal temperature, a large amount of inject in stove can cause temperature to reduce, increase the consumption of combustion gas.The exhaust piping of conventional anneal stove and guarantor
It is two independent pipelines to protect feed channel.EGT caused by annealing furnace is up to hundreds of degrees Celsius, does not obtain effective profit
With.And in the protective atmosphere injection stove of relative low temperature in-furnace temperature can be caused to reduce, it is the condition of high temperature in holding furnace, can burns
More combustion gas, cause gas consumption to increase.
The content of the invention
To solve the above problems, the utility model provides a kind of combustion gas annealing oven protective atmosphere heating system, including protection
Atmosphere generator, annealing furnace, by protecting feed channel to be connected between the protective atmosphere generating means and annealing furnace, annealing furnace
Interior to be provided with burning burner, burning burner is connected with exhaust piping；
The protection feed channel is provided with protective atmosphere part flow arrangement；
The protection feed channel is out of exhaust piping by playing a part of heated protective gas.The advantages of the utility model：
Heating system of the present utility model recycles to the waste gas of high temperature, heated protective atmosphere.Reduce low-temperature protection
Atmosphere is to the heat consumption in annealing furnace.By technological transformation, reduce 10% gas consumption.Greatly save and be produced into
This, improves product quality.
Brief description of the drawings
Fig. 1 is combustion gas annealing oven protective atmosphere heating system structural representation provided by the utility model；
Wherein
Protective atmosphere generating means 1, annealing furnace 2, feed channel 3 is protected, burn burner 4, exhaust piping 5, protective atmosphere point
Flow device 6.
Embodiment
Embodiment 1
Combustion gas annealing oven protective atmosphere heating system, including protective atmosphere generating means 1, annealing furnace 2, the protective atmosphere
Be provided with burning burner 4 by protecting feed channel 3 to be connected between generating means 1 and annealing furnace 2, in annealing furnace 2, burning burner 4 with
Exhaust piping 5 is connected；
The protection feed channel 3 is provided with protective atmosphere part flow arrangement 6；
Pipeline from protective atmosphere generating means 1 at protective atmosphere part flow arrangement 6 is blocked.
Cut out and 3 an equal amount of circular incision of protective atmosphere pipeline with gas welding in exhaust piping 5.
Circular incision of a size is equally cut out at the middle part of exhaust piping 5 according to actual heating state.
(increase elbow, valve, the new pipeline of welding etc.) is transformed the pipeline blocked to pass through on exhaust piping 5
Two circular incisions of cutting.
All otch are soldered to seamless, valve port sealing is tight.With protective atmosphere generating means 1 and protective atmosphere
Part flow arrangement 6 welds again.
When high-temp waste gas caused by annealing furnace work can realize mitigation guarantor to carrying out heating through its protective atmosphere
Protect atmosphere influences on the cooling in stove.Gas consumption is saved, reduces production cost, improves product quality.
