The heating furnace provided by the invention aims to overcome defects of the prior art and to provide the rotary-type full-automatic aluminum bar heating furnace which saves energy sources, heats uniformly, and has a simple structure and low cost.
Description
[technical field]
The present invention relates to a kind of Al squeezing material processing units, more specifically say a kind of rotary-type full-automatic aluminum bar heating furnace.
[background technology]
Before aluminium bar is squeezed into aluminium section bar, need to carry out slow uniform heating treatment to stub, existing aluminum-bar heating furnace is all the rectangle through type that is about 12 meters left and right, and head advances the body of heater that tail goes out, and there is following defect in existing process furnace:
1, energy consumption is high, and institute's loss heat energy can make the surrounding environment temperature rise worsen simultaneously
The fire door of inlet and outlet must be very large, and because the circulation of aluminium bar passes in and out and can't close, and must stretch out between the outer chain of body of heater and body of heater and can't seal, the hot gas in stove will directly distribute and be lost in outside air by convection current.Chain circulation turnover himself also can be taken a large amount of heats out of.Cause descent of temperature need to supplement with the outer factory building of stove in heat up and need the dual waste situation of the energy to be processed.
2, the occupied ground area is large
Through type linear pattern layout, 12 meters are long, and floor space is large, is unfavorable for the place layout.
3, heating poor quality
Because its heat source heats from a point or two some section faces, and heat tunnel speciality, can't guarantee that in stove, temperature is consistent, can cause like this aluminium bar heating inhomogeneous, can cause the aluminium bar temperature difference large, the warm not phenomenon in hot melt rod or surface blistering or not yet done surface or centre occurs, to extruding, brought difficulty, can't guarantee the squeezing prod quality.
4, use inconvenience
, because the through type aluminum-bar heating furnace can not pick and place arbitrarily wherein any aluminium bar, be unfavorable for automated operation and aluminium bar is heated memory.In addition, because the through type aluminum-bar heating furnace can only first outer, last-in, last-out, can not change the order of coming out of the stove, need the aluminium bar of heating various material and the aluminium bar of advanced stove while not using the aluminium bar that just needs with laggard stove, can only the taking-up of the aluminium bar of advanced stove is cooling, take out again the aluminium bar of laggard stove, will cause so a large amount of energy dissipations and cause the surrounding environment temperature rise to worsen, use inconvenience, operator's work under bad environment.
