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 is by the vertical sectional shape similar jet pipe array of setting on the flow deflector of annealing furnace side to the annealing object, make and spray all surfaces that the air-flow of coming can cover the annealing object targetedly by the jet pipe side, can not be wasted in the vacancy that need not to heat up, when the maximum that reaches air-flow is utilized effect, shorten annealing time.
Be specific embodiment below, referring to Fig. 1 to Fig. 4.
Jet pipe in a kind of annealing furnace, jet pipe 1 be positioned at the vertical side flow deflector of furnace bottom on, the array shape of being made up of at least two jet pipes 1 is similar to the vertical sectional shape of annealing object.
The Back Word shape that is shaped as intussusception of the array of jet pipe 1, this kind shape is favourable to the annealing effect with certain thickness annealing object.The similar intussusception shape of vertical sectional shape to the annealing object, can distribute a certain amount of air-flow respectively at edge, middle part, the core of annealing object, and not only rely on radially conducting heat successively of annealing object, the temperature equalisation and the consistent speed that raises of the object each several part of therefore can accelerating to anneal.
The intussusception number of Back Word shape can determine according to practical situation, and be not limited only to illustrate on the accompanying drawing two-layer; According to the difference of annealing object thickness and the selection of jet pipe caliber size, the intussusception number of Back Word shape can be greater than two-layer.
The fundamental figure of the Back Word shape of intussusception can be according to different change of vertical sectional shape of annealing object, can be circle, square, trilateral or irregular shape etc. and is beneficial to the shape that the annealing object heats up, and do not influence the realization of the utility model embodiment.
The jet pipe 1 that is positioned at Back Word shape center is arranged on the one-sided side flow deflector of annealing object, makes material roll up the pressure difference at core two ends, is convenient to air communication and crosses sleeve inner.And the core jet pipe 1 of adjacent jet pipe array is arranged on the annealing object not on the side flow deflector of homonymy, regulates the pressure equilibrium of body of heater inner body.For example, the core jet pipe 1 of first jet pipe array is arranged on the side flow deflector on the annealing object left side, and the core jet pipe 1 of second jet pipe array is arranged on the side flow deflector on annealing object the right, on the side flow deflector that the 3rd is arranged on the left side again.
The caliber size of jet pipe 1 can be unequal, as Fig. 1 to Fig. 4, can be divided into the medium less relatively little jet pipe 4 of middle jet pipe 3, bore of bore relatively large big jet pipe 2, bore; Can place the jet pipe of different bores according to actual needs flexibly, for example big jet pipe 2 is placed on the difficult zone that arrives of air-flow, little jet pipe 4 is placed on the too fast zone etc. of should not heating up.
The jet pipe of bore maximum can be placed on the center of jet pipe array, over against the core of annealing object; So that make the most difficult arrival of air-flow, the slowest core that heats up obtain the thermogenic action of mass air flow, be rapidly heated.
Obviously, the spacing of jet pipe 1 can equate or be unequal, determines according to practical situation, does not influence the realization of the utility model embodiment.
The jet pipe that is positioned at described jet pipe array center can be over against the medullary ray of annealing object vertical section, so that air-flow is imported core; And through experiment measuring and calculating proof, when the jet pipe that is positioned at jet pipe array center is the 1-5% of jet pipe array total height with the departure distance of the medullary ray of annealing object vertical section, fast slightly when the heat-up rate of core is compared jet pipe over against the medullary ray of annealing object vertical section.
And, when the downward-sloping 15-30 of jet pipe air outlet spends, help keeping contacting of certain angle with the annealing object from the air-flow that jet pipe passes through, help air-flow and stop the long period at the annealing article surface, further accelerate heat-up rate.
More than jet pipe in 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.
