Description
Technical field
The utility model relates to a kind of aluminum-bar heating furnace, the how excellent process furnace of heating-type in the middle of relating in particular to.
Background technology
Aluminium processing industry, raw material aluminium (aluminium ingot, aluminium bar) all can have heating process before carrying out rolling processing, and heating process completes at process furnace.Aluminum-bar heating furnace is a kind of heating unit being widely used, and process furnace provides heat energy by combustion engine, under recirculation blower high-pressure blowing-in, by the aluminium bar in the heating furnace of air channel.Heating process is often only considered to the preposition program of rolling processing, itself can not exert an influence to final product quality, so the new design of process furnace often considers that its level of automation promotes or energy-efficient performance promotes (as Chinese patent CN202660891U full-automatic aluminum bar heating furnace, and for example Chinese patent CN201062922Y preheating device of aluminum bar heating furnace); But in practice,, the heating process that process furnace is implemented can produce significant impact to product quality really, such as under certain condition, has eliminated the metal stresses of aluminium bar, makes aluminium shape surface brighter, and has better toughness etc.
Utility model content
The utility model discloses the how excellent process furnace of a kind of middle heating-type, it has improved each several part structure in burner hearth, makes the aluminium bar that enters process furnace can meet specific heating condition, thereby eliminates aluminium bar metal stresses, the aluminium shape surface that finally order squeezes out is brighter, and has better toughness.
For achieving the above object, the technical solution adopted in the utility model is: the how excellent process furnace of middle heating-type, comprise body of heater, bar device is turned in hydronics and transmission, before body of heater, rear have respectively feeding port and a blanking port, body of heater inside is formed with burner hearth, between burner hearth and body of heater, be provided with thermal insulation layer, hydronics device forms above body of heater and by recirculation blower and combustion engine, the heating air duct being welded by heat-resistance stainless steel extends into burner hearth, the air outlet of heating air duct be positioned at transmission turn over bar device middle part directly over, the vertical corresponding zone of air outlet is heating zone, region between heating zone and feeding port be preheating zone, region between heating zone and blanking port is heat preservation zone.
More optimizedly, heating zone at least holds year eight aluminium bars.
More optimizedly, the aluminium bar temperature of heating zone heating reaches 560 DEG C.
More optimizedly, turn over bar device transmission march to blanking port through the aluminium bar of heating zone heating by transmission, aluminium bar temperature drops to 480 DEG C ~ 520 DEG C.
And transmission is turned over bar device and at least held year ten six roots of sensation aluminium bars, transmission is turned over bar device one end and is connected feeding port, and the other end connects blanking port, and feeding port is higher than blanking port.
The starting point of the technical problem that the utility model solves is further improving product quality, aluminium bar enters after body of heater, first through the preliminary preheating in preheating zone, enter subsequently heating region, temperature is promoted to rapidly 560 DEG C, can evenly be reduced to slowly 480 DEG C ~ 520 DEG C that are applicable to pushing in heat preservation zone temperature afterwards, then blanking pushes, this operation makes aluminium bar have the process of individual heating anneal, can effectively eliminate aluminium bar metal stresses, make the aluminium profile product of extruding brighter, and there is better toughness.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
In conjunction with the accompanying drawings and embodiments the utility model is further illustrated.
As shown in Figure 1, the how excellent process furnace of middle heating-type, comprise body of heater 1, bar device 3 is turned in hydronics 2 and transmission, before body of heater 1, rear have respectively feeding port 10 and a blanking port 11, body of heater 1 inside is formed with burner hearth 12, between burner hearth 12 and body of heater, be provided with thermal insulation layer 13, hydronics 2 is installed above body of heater 1 and by recirculation blower 20 and combustion engine 21 and is formed, the heating air duct 22 being welded by heat-resistance stainless steel extends into burner hearth 12, the air outlet 23 of heating air duct be positioned at transmission turn over bar device 3 middle parts directly over, the vertical corresponding zone of air outlet 23 is heating zone 4, region between heating zone 4 and feeding port 10 be preheating zone 5, region between heating zone 4 and blanking port 11 is heat preservation zone 6.
In order further to raise the efficiency and to reach good implementation result, heating zone should be able at least hold carries eight aluminium bars, and bar device is turned in corresponding whole transmission at least should hold year ten six roots of sensation aluminium bars.The specification of aluminium bar can be from diameter Ф 70mm ~ Ф 500mm.
For realizing the effect of uniform decrease in temperature and reducing machinery and turn over bar device, the gradient that preheating zone to heat preservation zone keeps down, therefore, transmission is turned over bar device one end and is connected feeding port, and the other end connects blanking port, and feeding port is higher than blanking port.Aluminium bar enters after body of heater, first through approaching the preliminary preheating in preheating zone of feeding port, enter subsequently heating region, temperature is promoted to rapidly 560 DEG C, can evenly be reduced to slowly 480 DEG C ~ 520 DEG C that are applicable to pushing afterwards in heat preservation zone temperature, and then blanking pushes, this operation makes aluminium bar have the process of individual heating anneal, can effectively eliminate aluminium bar metal stresses, make the aluminium profile product of extruding brighter, and there is better toughness.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, not departing under the prerequisite of the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
