Heating furnace.
Background technology
Gas cylinder is manufactured using billet punching traction manipulation, first has to heat billet, and the square steel used at present
Base heating furnace has two kinds of step-by-step movement and a ring type, and wherein walking beam furnace is because simple in construction, and manufacturing cost is low, and floor space is small
And used by most of gas cylinder manufactories.Walking beam furnace also has its shortcoming, and one is that heating effect is general, temperature after material block heating
Difference is than larger；Two be walking beam furnace for a long time technology development it is slower.
Conventional walking beam furnace, by three regions in temperature field point, one is preheating zone, and two be heating zone, and three be uniform temperature zone,
The heat of preheating zone is by the radiation of heating zone, typically not separately installed heated nozzle.Heating zone according to the size of heating furnace,
2 heated nozzles are typically respectively mounted in body of heater both sides, to heat material block.The setting height(from bottom) of heated nozzle is according to the space of body of heater
And the size of material block is determined, typically on the basis of heating flame can not be directly injected to material block surface, to prevent during material block heating
Cross thermal oxide.Expect that on furnace bottom guide rail, material block is promoted using hydraulic jack for block cross arrangement in heating furnace, material block is preheated
After area, heating zone, uniform temperature zone, block surface temperature to be expected reaches that 1280 ± 10 DEG C discharge again；
Heated nozzle is controlled according to temperature in burner hearth using automatic large and small fire, and when in-furnace temperature is higher, nozzle is opened small automatically
Fire, when in-furnace temperature is relatively low, nozzle opens big fire with concurrent heating automatically.The temperature and heating effect of heating furnace burner hearth, directly affect material
The temperature homogeneity and productive temp of block.Expect that deblocking temperature is uneven, will result directly in punching bottle base bottle base in extrusion process
Wall thickness deviation increases, and causes the unqualified and weight of bottle base to waste.Meanwhile, expect that the temperature unevenness of block is made in long-term punching press
Under, the accuracy of alignment system of the meeting whole press of heavy damage, serious possibility has influence on whole press structure.Expect block heating energy
Power is not enough, causes material block central temperature not reach forming temperature, causes to press not on earth during punching press, bottle base is scrapped, universal during manufacture
Improved with lengthening productive temp time the heat time of heating furnace, influence production efficiency.
But due to not substantially being spaced between three sections, adjacent sections temperature field can influence each other, and cause fire box temperature
Display distortion, preferable heating effect is not reached finally.In addition, material block is in heating process, upper surface is heated by temperature field, temperature
Degree is raised comparatively fast, and lower surface is slower by guide rail transmission thermal temperature rising, and such as equal temperature time is inadequate, the temperature difference of upper and lower surface
To be bigger.
Utility model content
The utility model provides a kind of billet heating walking beam furnace, solves traditional heating stove each section
It is not spaced, causes the problem of temperature control fails because temperature field influences each other.
A kind of billet heating walking beam furnace, including body of heater, the furnace interior are led provided with conveying billet
Rail, the body of heater includes preheating zone, heating zone and uniform temperature zone, and partition wall, the partition wall are provided between the heating zone and preheating zone
Located at the top of guide rail, cooling water pipe is laid with the partition wall, the cooling water pipe two ends are attached across sidewall of the furnace body respectively
Water inlet pipe and outlet pipe.
It is preferred that, it is provided with discharging opening close to guide rail discharging end position along the sidewall of the furnace body of body of heater length direction.
It is preferred that, the sidewall of the furnace body in face of billet moving direction is provided with the first burner pair.
It is preferred that, the sidewall of the furnace body where heating zone is provided with the second burner pair and the 3rd burner pair, wherein the second burner
It is pointed to above guide rail, the 3rd burner is pointed to below guide rail, the second burner pair and the 3rd burner are to being arranged at intervals.
It is preferred that, set the sidewall of the furnace body of burner to be provided with the horizontally disposed fire jetting hole connected with burner hearth, the burner
Stretched into outside body of heater in fire jetting hole.
It is preferred that, the partition wall is arc arch shape.
It is preferred that, reclined at the top of the partition wall with body of heater roof, two ends insertion sidewall of the furnace body.
The beneficial effect that the utility model possesses：
The utility model is provided with partition wall in heating zone and uniform temperature zone, weakens influencing each other for two zone temperatures, makes
Obtain fire box temperature control more accurate, cooling water pipe is set in partition wall in addition, high temperature can be reduced partition wall is impacted, improve it
Service life.

Fig. 2 is the utility model walking beam furnace transverse cross-sectional view.
Fig. 3 is the utility model walking beam furnace section structure schematic diagram.
Embodiment
As illustrated in fig. 1 and 2, conveying side is provided with a kind of billet heating walking beam furnace, including body of heater 1, body of heater 1
The guide rail 2 of steel billet 4.1 point of body of heater is preheating zone 11,13 3 sections in heating zone 12 and uniform temperature zone, and three sections do not have strict bounded
Limit, the utility model is to prevent influencing each other for adjacent sections, especially heating zone 12 and the temperature field of uniform temperature zone 13, in heating zone
Partition wall 3 is provided between 12 and uniform temperature zone 13.
As shown in figure 3, partition wall 3 is poured by cement, substantially in arc arch shape, top and the roof of body of heater 1 recline, two ends insertion
The side wall of body of heater, can effectively prevent influencing each other for adjacent sections temperature field, to reach the purpose of accurate temperature controlling.Partition wall 3 is not
Guide rail is preferably too near to, the heat transfer of adjacent sections is otherwise influenceed.In order to prevent high temperature impact from causing partition wall to collapse, laid in partition wall
There is cooling water pipe 31, cooling water pipe two ends 31 are attached across the water inlet pipe 32 and outlet pipe 33 of sidewall of the furnace body respectively, pass through heat friendship
Wall heat of changing commanders is taken away.
The side wall of body of heater 1 has four pairs of burners, and wherein burner is to 5 tail ends for being located at body of heater, i.e., in face of the firm moving direction of base 4 in side
Sidewall of the furnace body on, its excess-three to burner be located at heating zone where sidewall of the furnace body on.Wherein burner is located at guide rail 2 to 7,8
Top, burner is to 6 lower sections for being located at guide rail 2, and burner is located at burner to 6 between 7,8, it is ensured that homogeneous heating.In heating zone,
Paired burner, respectively positioned at the both sides of heating zone, and just to setting；There is burner hearth above and below guide rail 2, in body of heater
Side wall is provided with fire jetting hole 9, and burner is stretched into outside body of heater in fire jetting hole 9.Fire jetting hole is connected with burner hearth, after fuel gas buring, and heat enters
Enter burner hearth, rather than directly against the heating of the direct flame of billet 4.
Along the side wall of body of heater length direction, discharging opening 10 is provided with close to the position of the discharge end of guide rail 2, because heat can not be kept away
Exempt to shed from discharging opening, therefore burner can make up the heat of the partial loss to 5 continuous heating.But burner is direct to 5
Jet flames, can influence the temperature control of heating zone, because partition wall 3 is just against burner to 5, can eliminate most of influence.
