Description
Technical field：
The utility model belongs to technical field of heat treatment, and in particular to a kind of flames of anger combustion gas samming heater.
Background technology：
During some workpiece heats, workpiece is slowly heated and long-term heat preservation, workpiece pair at a temperature of less than 600 DEG C
The change of surface temperature and core temperature is very sensitive, if uneven easily cause the uneven of inside workpiece tissue, or even work
Part turns into defective work.It is based on convection heat transfer' heat-transfer by convection, supplemented by radiant heat transfer, and to be added using combustion gas at a temperature of less than 600 DEG C
The naked light that hot then gas flame is produced turns into prominent infrared source, and the caloradiance of the radiation source is remote due to workpiece
Closely, the difference of angle, hence it is evident that be uneven, the operation of especially workpiece is very slow, such as extended stationary periods burn in a combustion gas
Near mouth, serious uneven of workpiece temperature can be caused, or even as waste product.
It can fluctuate burner heat capacity by space gas pressure fluctuations using fuel burner nozzle, cause heating-up temperature
Fluctuation is produced, this does not allow on the heating requirements of some workpiece, and space gas pressure oscillation is inevitable, simply one
Totally keep constant in individual large period, the problem wants very big by controlling space gas pressure oscillation to put into, and effect is not also good.
The content of the invention：
There is provided a kind of flames of anger combustion gas samming heater in view of the above-mentioned problems existing in the prior art for the utility model.
The utility model device effectively can open the naked light radiation of fuel burner nozzle with work-piece isolation, while fuel burner nozzle can be produced
High-temperature flue gas uniformly forms convection current, rapidly and uniformly can heat and play insulation effect.
A kind of flames of anger combustion gas samming heater provided by the utility model include heating furnace body 1, fuel burner nozzle 4 and
Samming fire insulation case 3；The samming fire insulation case 3 is arranged on the bottom of heating furnace body 1, and the samming fire insulation case 3 is located at the combustion gas
The top in the exit of burner 4；The fuel burner nozzle 4 is arranged on the bottom furnace wall of the heating furnace body 1.
The top of heating furnace body 1 is provided with charging aperture, and the charging aperture is used to heated workpiece 2 being placed on the samming
The top of fire insulation case 3.
The samming fire insulation case 3 is formed by heavy refractory material laying, the samming fire insulation case 3 have big thermal capacity and
Thermal inertia, the samming fire insulation case 3 is after a period of time is heated, and heavy refractory material, which is heated to after certain temperature, forms steady
Fixed thermal source, the stabilization for temperature forms facilitation.
Uniform smoke distribution hole on the samming fire insulation case 3.
The smoke distribution hole is the cylindrical hole symmetrically set.
The fuel burner nozzle 4 is high-speed fuel gas burner.
The utility model is separated flame with heated workpiece using samming fire insulation case, and heated workpiece is placed in samming fire insulation
Above case, flame and high-temperature flue gas spread apart after samming fire insulation case is entered and, the height that fuel burner nozzle is sprayed into samming fire insulation case
Warm flue gas uniformly rises behind the smoke distribution hole by soaking fire insulation upper box part, is heated to being heated workpiece, while naked light
Flame is isolated by samming fire insulation case, makes to be heated workpiece and will not be directly exposed in naked light radiation to cause the inequality of workpiece surface temperature
It is even.Samming fire insulation case by high-temperature flue gas after being heated, using the thermal inertia and heat storage capacity of samming fire insulation case refractory material, makes
The more uniform temperature of warm fire insulation case, is influenceed smaller, temperature is more constant by space gas pressure oscillation before fuel burner nozzle.
Samming fire insulation case is formed by heavy refractory material laying, there is very big thermal capacity, and thermal inertia is very big, is being heated
After a period of time, refractory material, which is heated to, forms stable thermal source after certain temperature, promotes to make for stable formed of temperature
With even if space gas has fluctuation in the pressure short time, will not also there is big influence to the flue-gas temperature of heated partses, it is ensured that heating
Temperature stabilization within the specific limits, facilitation is played for improving temperature-controlled precision.
The utility model has following technical characterstic：
1st, the utility model is acted on using the premix of high-speed fuel gas burner, makes combustion gas and air in the combustion of high-speed fuel gas burner
Indoor Combustion is burnt, it is 200mm or so to make the drop of the flame, reduce naked light and uneven influence is radiated to workpiece.
2nd, the characteristics of the utility model is high using the flue gas flow rate of high-speed fuel gas burner, enters to the gas in samming fire insulation case
Row is sufficiently stirred for, and makes that the gas temperature in samming fire insulation case is basically identical, and the uniformity to workpiece temperature plays facilitation.
3rd, the utility model utilizes samming fire insulation case, in low-temperature condition（Less than 600 DEG C) under bright Fire Radiation easily cause plus
Heated work pieces surface temperature is uneven, has completely cut off the radiation of fuel burner nozzle naked light, workpiece is not radiated by burner naked light uneven
Influence.
4th, the utility model makes high-temperature flue gas uniformly rise using the uniform smoke distribution hole of samming fire insulation upper box part, rises
To the effect heated to workpiece even convective.
5th, the utility model is attached most importance to fire resistant materials using the material of samming fire insulation case, plays storage exothermic effects, utilizes weight
The characteristics of fire resistant materials thermal inertia is big, when space gas pressure has fluctuation before fuel burner nozzle, reduces fluctuation to flue-gas temperature
Influence, improves temperature controlled precision and stability.The utility model can make the surface of workpiece, the control of the core temperature difference ± 5
Within DEG C, while Control for Kiln Temperature precision can be also controlled within ± 5 DEG C.
