Common technology.Annealing furnace is process equipment indispensable in annealing processing, and the aluminium after aluminium coil and sheet stack annealing furnace is suitable for rolling is rolled up
Material is annealed again to be handled to meet the next step processing technology of aluminium coiled material.Aluminium rolls up annealing treating process and requires furnace gas temperature uniformity
High temperature difference is less than or equal to 3 DEG C of scholar.The fuel that current most of aluminium coil and sheet stack annealing furnaces are adopted is from the burner for being installed on annealing furnace sidewall
It feeds in furnace, due to the influence of the factors such as material resistance, gas flowing and hot gas floating, high-temperature gas can not be reached under aluminium volume
Portion center causes the position heat supply insufficient, in order to compensate for this defect, can only extend the soaking time of annealing.Thus bring
Problem is that center and the heat distribution unevenness on periphery, annealing time are too long, and then affect the quality of product, and energy consumption of annealing
It is excessively high.
Three, summary of the invention
The purpose of the utility model is to provide a kind of aluminium to roll up annealing furnace, can guarantee that in-furnace temperature is uniform, reduces in furnace
The temperature difference, and then improve aluminium and roll up product quality.
The utility model technical solution used for the above purpose is: a kind of aluminium volume annealing furnace, including furnace shell, furnace
Wall, burner, smoke outlet, the burner are mounted in an inclined manner in the left and right side walls of furnace wall, the axis and water of the burner
The angle of horizontal line is 30 °, and left and right side walls is mounted on two rows of burners for being parallel to annealing furnace body length direction, is located at same height
The burner in left and right side walls on degree is alternatively arranged, wherein the burning in the left and right side walls on the same cross section of the furnace body
Mouth is centrosymmetric about the central point of cross section, and the burner close to the bottom of furnace body tiltedly sprays upward, close to the furnace body
The burner at top tiltedly sprays downward, and the furnace wall has been correspondingly formed flame ejiction opening, and the smoke outlet is located at furnace wall back-end wall
Middle part.
Further, the squit hole of the burner is set as 450mm-600mm to the linear distance that aluminium is rolled up.
Further, the fuel of the burner is natural gas or coke-stove gas.
Further, the furnace shell is fire resisting stainless steel.
Further, the furnace wall is ceramic fiber layer.
Further, the external induced-draft fan of the smoke outlet.
The utility model compared with prior art, has the following advantages and beneficial effects: the aluminium volume annealing of the utility model
The burner of furnace is arranged by inclined mode, is 30 ° with horizontal angle, the burner on the same cross section of furnace body about
The central point of cross section is in center point symmetry, and furnace atmosphere can be sufficiently stirred in the burner symmetrically sprayed, wherein close to furnace body bottom
The burner in portion tiltedly sprays upward, and the burner at the top of furnace body tiltedly sprays downward, can be avoided the direct-injection that bottom nozzle rolls up aluminium
The phenomenon that causing aluminium to roll up epidermis burning, meanwhile, the injection direction of the burner of adjacent cross sectional intersects, and further enhances along furnace
The heat exchange in body length direction reduces the temperature difference in furnace so as to guarantee that in-furnace temperature is uniform, and then improves aluminium and roll up product matter
Amount.
Four, Detailed description of the invention
Fig. 1 is the aluminium volume annealing furnace structure schematic diagram of the utility model；
Fig. 2 is the diagrammatic cross-section of the A-A of Fig. 1；
Fig. 3 is the diagrammatic cross-section of the B-B of Fig. 1.
Specific embodiment
Detailed description furtherly is made to the utility model in the following with reference to the drawings and specific embodiments, so as to this field skill
Art personnel understand.
As shown in Figure 1-3, a kind of aluminium of the utility model rolls up annealing furnace, including furnace shell 1, furnace wall 2, burner 3, smoke outlet 4,
The burner 3 is mounted in an inclined manner in the left and right side walls of furnace wall 2, and axis and the horizontal angle of the burner 3 are
30 °, left and right side walls is mounted on two rows of burners 3 for being parallel to annealing furnace body length direction, the left and right on sustained height
Burner 3 on side wall is alternatively arranged, wherein the burner 3 in the left and right side walls on the same cross section of the furnace body is about cross
The central point in section is centrosymmetric, and the burner 3 close to the bottom of furnace body tiltedly sprays upward, the burning at the top of the furnace body
Mouth 3 tiltedly sprays downward, and the furnace wall 2 has been correspondingly formed flame ejiction opening 5, and the smoke outlet 4 is located in 2 back-end wall of furnace wall
Portion.The distributing position of the flame ejiction opening 5 on furnace wall 2 is shown in Fig. 1, the black flame ejiction opening on the wall of left side of getting the bid
5, the black flame ejiction opening 5 in right-side wall is not marked.The aluminium of the utility model rolls up annealing furnace, is located on the same cross section of furnace body
Burner 3 about kernel of section point symmetry, furnace atmosphere can be sufficiently stirred in the burner 3 symmetrically sprayed, close to bottom of furnace body
Burner 3 tiltedly sprays upward, and the burner 3 at the top of furnace body tiltedly sprays downward, can be avoided the direct-injection that bottom nozzle 3 rolls up aluminium and makes
The phenomenon that rolling up epidermis burning at aluminium, meanwhile, the injection direction of the burner 3 of adjacent cross sectional intersects, and further enhances along furnace
