Abstract
The utility model relates to a steel cylinder normalizing furnace used in normalizing treatment of liquefied gas steel cylinder, and solves the problems of the prior steel cylinder normalizing furnace such as frequent replacement of furnace chains and high maintenance and operating costs. The utility model comprises a furnace body, a chain type conveying mechanism, a suspension hook and a burner, wherein, the chain type conveying mechanism is arranged at the upper part of the furnace body; a furnace roof is provided with a through groove extending in longitudinal direction; the upper end of the connecting rod passing through the through groove is connected with the chain type conveying mechanism, while the lower end is connected with the suspension hook arranged inside the furnace body.
Description
Technology neck city
The utility model relates to heat treatment furnace, especially cylinder for liquefied gas is carried out the steel cylinder normalizing furnace of normalizing treatment.
Background technology
Domestic bigger steel cylinder manufacturing concern generally adopts chain-type to drive steel cylinder normalizing furnace and high charging, hangs down discharge roller dynamic formula normalizing furnace at present.
Chain-type drives the steel cylinder normalizing furnace, comprises body of heater, is arranged on that stove is intravital, the chain conveyor structure that transports steel cylinder, suspension hook, burner etc.Because the high temperature steel chain of the support drive steel cylinder in the chain conveyor structure is in body of heater, it moves traction under the long term high temperature state, and chain sheet tensile deformation well damage needs often to change chain, has increased maintenance cost.
High charging, low discharge roller dynamic formula normalizing furnace, because of burner on steel cylinder, the furnace temperature upper and lower temperature difference in the burner hearth is excessive, poor temperature uniformity, and flame can directly contact with workpiece, makes workpiece surface generation burning and oxidation.Walking makes oxide skin easily drop into the direct conveying that influences work in heap knot back, bottom because workpiece rolls in stove in addition, also influences the circulation of hot gas flow to the stove.
Summary of the invention
What the utility model solved is that existing steel cylinder normalizing furnace chain needs often to change, the high problem of maintenance running cost.
This steel cylinder normalizing furnace comprises body of heater, chain conveyor structure, suspension hook, burner; The chain conveyor structure is arranged on upper of furnace body, has the groove that extends longitudinally on furnace roof, passes the union lever upper end chain formula transfer mechanism of groove, the suspension hook in the following termination body of heater.
The utility model, the chain conveyor structure is arranged on the body of heater outside, by union lever suspension hook is linked to each other with the chain conveyor structure.Workpiece hangs on the suspension hook, and the action of chain conveyor structure makes workpiece pass through the burner hearth even heating.Because of chain outside burner hearth, no longer be subjected to heat, the transfer mechanism chain is reliability service for a long time.
For prevent from that heat scatters and disappears to the outside from groove, can on union lever, connect to cover groove and with the contacted heat insulation planker of furnace roof upper surface.Certainly, best heat insulation planker communicates with the air curtain pipe with contact surface between the furnace roof upper surface, and the air curtain pipe the other end communicates with the seal fan air outlet.Seal fan work is blown contact surface between heat insulation planker and furnace roof upper surface with wind by the air curtain pipe, forms the air curtain of sealing, and it is isolated that hot gas flow and stove outer air are formed, and further prevented the lost of furnace heat.
In order to make that temperature homogeneity is better in the burner hearth, and preventing that flame from directly contacting with workpiece causes workpiece surface generation burning and oxidation, for any steel cylinder normalizing furnace recited above, can engine firewall be set in the lower furnace portion of body of heater, in the engine firewall bottom burner is set, communicates with the blast inlet of smoke exhaust fan on the top of burner hearth.During use, smoke exhaust fan work makes to reach micro-vacuum state in the stove, and the warm air by heater heats promptly is looped around around the steel cylinder, and temperature is not only even in the burner hearth, and, there is not heat to be siphoned away substantially by smoke exhaust fan.
Description of drawings
Fig. 1. be main TV structure figure of the present utility model.
Fig. 2 is the side cutaway view of the A-A of Fig. 1.
Fig. 3 is the partial enlarged drawing of Fig. 2.
Among the figure, 1 smoking divider; 2 seal fans; 3 chain conveyor structures; 4 combustion chambers; 5 engine firewalls; 6 burners; 7 suspension hooks; 8 steel cylinders; 9 smoke exhaust fans; 10 smoke evacuation pipelines; 11 heat insulation plankers; 12 air curtain pipes; 13 dampers; 14 bracing frames; 15 bodies of heater; 16 grooves; 17 union levers; 18 furnace roof upper surfaces.
Embodiment
Further specify the utility model below in conjunction with Fig. 1,2.
Steel cylinder normalizing furnace shown in Fig. 1,2 comprises parts such as body of heater 15, chain conveyor structure 3, suspension hook 7, burner 6.Chain conveyor structure 3 is arranged on upper of furnace body.On furnace roof, have the groove 16 that extends longitudinally.Union lever 17 passes groove 16, its upper end chain formula transfer mechanism, the suspension hook 7 in the following termination body of heater.Connect on the union lever 17 cover groove 16 and with the contacted heat insulation planker 11 of furnace roof upper surface.Heat insulation planker 11 communicates with air curtain pipe 12 with the contact surface of 18 of furnace roof upper surfaces, and the air curtain pipe the other end communicates with seal fan 2 air outlets.In the intravital lower furnace portion of stove engine firewall 5 is set, burner 6 is set in the body of heater both sides of engine firewall bottom.The both sides, top of burner hearth communicate with the blast inlet of smoke exhaust fan 9 by smoke evacuation pipeline 10.
Burner 6 evenly passes engine firewall 5 in body of heater both sides lower heating by combustion chamber 4, guarantees that flame is not directly injected on the workpiece, and hot gas flow flows to the working spaces to steel cylinder 8 heating, and flue gas is discharged by smoke evacuation pipeline 10.
The groove at steel cylinder normalizing furnace top is heat insulation, adopts maze-type structure; And groove topped heat insulation planker suitable for reading; To the contact surface between heat insulation planker and furnace roof upper surface, longitudinally length direction forms an air curtain state to seal fan on furnace roof top by the air-supply of air curtain pipe; These measures all make interior hot gas flow of stove and stove outer air form isolated.
During opened smoke-discharging blower fan 9, be arranged on the smoking divider 1 of smoke evacuation in the pipeline by adjustment, damper 13 makes smoke evacuation pipeline 10 and smoke exhaust fan 9 cold and hot air mixed, so that steel cylinder normalizing furnace two ends fire door and furnace roof are in little negative pressure is optimum regime, the operator stands in the excessive phenomenon of the also imperceptible hot gas flow in fire door place, two ends, to reduce temperature in the excessive and too much extraction of the furnace gas stove.
During use, steel cylinder 8 is opened chain conveyor structure 3 by manually directly hanging over above the outer suspension hook 7 of body of heater, and steel cylinder 8 heats, cools off, is sent to discharging area through normalizing furnace, manually steel cylinder 8 is laid down, and repeats above-mentioned action continuously and gets final product.
Smoking divider 1, damper 13, chain conveyor structure 3, burner 6 etc. all belong to existing technology, no longer describe.
Present embodiment reasonable integral structure, workpiece are carried steadily, and loading and unloading are convenient, temperature evenly (homogeneity ± 10 ℃) in the stove, and it is indeformable that workpiece is handled the back.
