Abstract
The utility model discloses a bottom blowing device for an annealing furnace. The bottom blowing device is a baffle at the bottom of the annealing furnace, wherein the baffle is provided with at least two ventilation openings, and each ventilation opening is just against at least one support frame for the annealing objects. As the bottom of the annealing furnace is divided into multiple ventilation openings just against the annealing objects, the airflow are concentrated so as to warm the individual annealing object, therefore, the warming speed is accelerated.
Description
Technical field
The utility model relates to metal charge volume annealing technology field, relates in particular to a kind of bottom blowing device of annealing furnace.
Background technology
Annealing is the important step in the aluminium production process, be to keep the enough time after the aluminium volume is worked into certain temperature, slowly cooling again, main purpose is: (1) is improved or eliminate various tissue defects and the unrelieved stress that aluminium is caused in casting, forging and pressing, rolling and welding process, prevents workpiece deformation, cracking; (2) softening workpiece is so that carry out machining; (3) crystal grain thinning improves tissue to improve the mechanical property of workpiece.
Annealing furnace is the Equipment for Heating Processing of carrying out anneal, and its structure comprises that the material volume of blower fan, hot-plate and the bottom of furnace body at body of heater, body of heater top supports object.The air of body of heater inner top is after the hot-plate heating, naturally fall furnace bottom from furnace roof, be subjected to the upwards suction of suction of blower fan again, be sucked into the top through punishment in advance volume put area, then hot-plate heats air once more, forms high temperature gas flow intermittent type in annealing furnace thus and forces internal recycle.
Material volume is to be rolled into by thousands of layers of thin plate, but the high temperature gas flow in the existing annealing furnace can only be to the outside surface conduction heating of material volume, and the heat radiation that material volume core can only outer surface and heating up gradually needs the long period just can make material volume internal and external temperature all reach tapping temperature; And the bottom of existing annealing furnace is one and the inner full communicating open space of body of heater.Therefore, existing annealing furnace annealing time is long, and production efficiency is low, and energy dissipation is big.
The utility model content
The utility model embodiment provides a kind of bottom blowing device of annealing furnace, and this bottom blowing device is divided at the bottom of with annealing furnace over against a plurality of ventilation openings of annealing object, makes air-flow to concentrate one annealing object is heated up, and accelerates heat-up rate.
For achieving the above object, the utility model embodiment provides following technical scheme:
A kind of bottom blowing device of annealing furnace, this device are the baffle plate that annealing furnace bottom one has at least two ventilation openings, and each ventilation opening is over against the bracing frame of at least one annealing object.
Preferably, the number of this ventilation opening is identical with the bracing frame number of annealing object.
Preferably, the shape of this ventilation opening adapts with the bottom surface projection of shape of annealing object.
Preferably, the area of this ventilation opening is greater than the bottom surface shadow area of annealing object.
Preferably, this ventilation opening is provided with air door.
Preferably, the width of this ventilation opening is 1.5-3 highly times.
Compared with prior art, the utlity model has following beneficial effect:
1, strengthen the specific aim of air-flow: the ventilation opening of bottom blowing device is over against the annealing object, will directly lead from the air-flow of ventilation opening ejection annealing object bottom and middle and lower part, and do not allow high temperature gas flow be dispersed in the air, improve annealing efficiency;
2, the thermogenic action that adds blast air: air-flow sprays to annealing object bottom and middle and lower part, and the surface temperature that can directly drive the annealing object raises, and accelerates heat-up rate.

Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment makes air-flow to concentrate one annealing object is heated up by being divided at the bottom of the annealing furnace over against a plurality of ventilation openings of annealing object, accelerates heat-up rate.
Below be specific embodiment, referring to Fig. 1 and Fig. 2.
A kind of bottom blowing device of annealing furnace, this device are the baffle plate 1 that annealing furnace bottom one has at least two ventilation openings 2, and each ventilation opening 2 is over against the bracing frame of at least one annealing object.
Ventilation opening 2 is over against the bracing frame of annealing object, the air-flow from ventilation opening ejection directly can be led annealing object bottom and middle and lower part, and do not allow high temperature gas flow be dispersed in the air, improve annealing efficiency.
The number of ventilation opening 2 can be identical with the bracing frame number of annealing object, and promptly ventilation opening 2 forms man-to-man relation with the annealing object, make each annealing object all have independent air-flow from the bottom to rising, guarantee the annealing effect.
Referring to Fig. 2 and Fig. 3, the shape of ventilation opening 2 can adapt with the bottom surface projection of shape of annealing object, can be square, oval, rhombus, trilateral or irregular shape, so can more snugly air-flow be guided to the object bottom periphery of annealing.For example, the bottom surface of the material volume of laterally placing is projected as square, and the bottom surface of the material volume of vertically placing is projected as circle, and the bottom surface that has a cup of handle is projected as circle and adds square etc.
The area of ventilation opening 2 is reserved certain space in the bottom periphery of annealing object to air-flow during greater than the bottom surface shadow area of annealing object, is beneficial to annealing.
Ventilation opening 2 can be provided with air door, then can select the use number and the usable floor area of ventilation opening 2 according to the actual requirements, and is convenient and practical.
The width of ventilation opening 2 be the height 1.5-3 times the time, enough airsheds can be provided, reach the effect of annealing preferably.
More than the bottom blowing device of a kind of annealing furnace that the utility model embodiment is provided be described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in summary, this description should not be construed as restriction of the present utility model.
