Description
Technical field
The present invention relates to a kind of heating furnace, in particular to a kind of aluminum-bar heating furnace.
Background technique
Aluminum profile is a kind of common material in construction and decoration field.Aluminum profile is needed first to be sent into aluminium bar before shaping and be heated
500 degrees Celsius or more are heated in furnace just can be carried out extrusion forming.Traditional aluminum-bar heating furnace is usually to use upper heating method,
That is, high-temperature flue gas sprays into burner hearth from upper furnace, the aluminium bar in burner hearth is heated.However, this upper heating method is easy
Cause aluminium bar bottom temp lower, the final final product quality for influencing aluminum profile.
A kind of novel rapid fuel gas aluminum bar heating furnace as disclosed in Chinese patent discloses No. 202297690U, including furnace
Body, furnace body support, aluminium bar conveying roller, roller support, flue gas jet pipe, smoke conveying duct, waste heat recovery pipe road；Wherein flue gas jet pipe
One end connects upper of furnace body, and the other end connects smoke conveying duct；Waste heat recovery pipe road is located at lower portion of furnace body and is connected with furnace body；
Aluminium bar conveying roller is located in roller support, and aluminium bar conveying roller passes through furnace body, the axis direction of aluminium bar conveying roller and the axis side of furnace body
To vertical, aluminium bar longitudinal arrangement is on aluminium bar conveying roller.As it can be seen that the novel rapid fuel gas aluminum bar heating furnace is using upper heating
Mode, this is easy to cause aluminium bar uneven heating even.
For another example Chinese patent discloses a kind of aluminum-bar heating furnace of No. 202470754U announcement, includes furnace body, further includes
There is the fan housing covered on furnace body and be placed in bottom of furnace body and its flame is directly in the surface heated burner of aluminium bar to be processed,
In, fan housing completely covers aluminium bar to be processed, while the fan housing is in up-small and down-big structure, and its air duct at top and burner
Circulating fan be connected, pass through above-mentioned circulating fan and the intracorporal hot wind of furnace driven to form negative-pressure cyclic.Although the aluminium bar heats
Furnace using bottom-heated mode, however its there are still following disadvantage or deficiencies: (1), it uses a burner, and produces
Raw flame is just injected directly into burner hearth bottom without shunting, and causes the temperature at burner hearth center excessively high, and the temperature of burner two sides
It is lower；(2), similarly, the temperature of the burner hearth leading portion of neighbouring burner is higher, and the temperature of the burner hearth back segment far from burner compared with
