Background
The multifunctional continuous annealing furnace can realize various annealing processes and normalizing processes, and a small number of annealing furnaces can also realize an isothermal normalizing function. One furnace can realize a plurality of processes, the control requirements of each process on the furnace temperature are very different, and in order to meet the requirements of different processes, some furnace sections have to have the functions of heating and cooling at the same time. The cooling method is generally adopted, wherein hot gas in the furnace is cooled by a furnace top heat exchanger and then is sprayed into the furnace for cyclic reciprocation. In order to ensure an effective cooling process, certain requirements are imposed on the low-temperature furnace gas sprayed into the furnace, whether the low-temperature furnace gas is sprayed in a spraying form or in a spraying amount. Therefore, the structural form of the cold air spray pipe in the furnace is particularly critical. The stability of the quality of the normalizing and isothermal normalizing products is often closely related to the form of the nozzles in the furnace.
The existing cold air spray pipe in the furnace is square, and honeycomb ducts are uniformly distributed on the spray pipe. The structure can not ensure the pressure consistency of the blowing openings at the far end and the near end of the nozzle, and finally the cooling speed of different positions of the heat-treated steel can be different, so that the product quality is unstable.
Disclosure of Invention
The utility model aims to solve the technical problem that the problem that exists lies in to the aforesaid provides a continuous annealing stove rapid cooling jetting device, has carried out optimal design to original spray tube, improves the unbalanced phenomenon of pressure.
The utility model provides a technical scheme that above-mentioned technical problem adopted is: the utility model provides a quick cooling jetting device of continuous annealing stove which characterized in that: including spray tube body and flow equalizing pipe, be equipped with several honeycomb ducts along the even interval of axial on the spray tube body, insert the spray tube body in the flow equalizing pipe, set up well with spray tube body center, form the flow equalizing chamber, be equipped with the several through-hole along the even interval of axial on the flow equalizing pipe, through-hole and honeycomb duct longitudinal symmetry set up.
According to the scheme, the outer wall of the flow equalizing pipe is provided with the positioning devices at even intervals along the axial direction, and the positioning devices are positioning columns which are evenly distributed at intervals along the circumferential direction.
According to the scheme, the pipe orifice of the flow equalizing pipe is provided with the welding flange and is connected with the inner wall of the pipe orifice of the spray pipe body in a welding mode through the welding flange.
According to the scheme, the fiber blanket is filled at the top of the flow equalizing cavity.
According to the scheme, the spray pipe body and the flow equalizing pipe are of circular pipe structures.
According to the scheme, the pipe orifice of the spray pipe body is provided with the connecting flange, and the tail pipe is supported.
The utility model has the advantages that: the utility model provides a quick cooling jetting device of annealing stove in succession, at first the spray tube structure changes into circularly, adds a flow equalizing pipe in spray tube inside, lets cold stove gas get into the spray tube after the flow equalizing pipe mixing earlier, improves the unbalanced phenomenon of pressure, though can't guarantee that every honeycomb duct spun pressure is identical completely through the spray tube after flow equalizing treatment, but improved the uneven phenomenon of pressure in the very big degree, also can not cause the influence to the quality of product almost.

Detailed Description
For a better understanding of the present invention, the following description is given in conjunction with the accompanying drawings and examples.
As shown in figures 1-3, a rapid cooling and blowing device of a continuous annealing furnace comprises a spray pipe body 1 and a flow equalizing pipe 2, wherein a plurality of flow guide pipes 3 are uniformly arranged on the spray pipe body at intervals along the axial direction, the flow equalizing pipe is inserted into the spray pipe body and is arranged in alignment with the center of the spray pipe body to form a flow equalizing cavity, a plurality of through holes 4 are uniformly arranged on the flow equalizing pipe at intervals along the axial direction, and the through holes and the flow guide pipes are arranged in a vertically symmetrical manner. The low-temperature furnace gas firstly enters the flow equalizing pipe and is discharged from the through hole, and is sprayed out through the flow guide pipe after being converged in the flow equalizing cavity, so that the problem of unbalanced pressure of the flow guide pipe is solved.
And positioning devices are uniformly arranged on the outer wall of the flow equalizing pipe at intervals along the axial direction, and are positioning columns 5 uniformly distributed at intervals along the circumferential direction. The flow equalizing pipe is supported by the positioning column, always keeps being aligned with the center of the spray pipe body, does not deflect and deform, and better achieves the flow equalizing effect.
The mouth of pipe of flow equalizing pipe is equipped with welding flange 6, and the mouth of pipe inner wall welding that passes through welding flange and spray tube body links to each other.
The top of the flow equalizing cavity is filled with a fiber blanket 7, which plays a role of heat insulation and prevents the thermal deformation of the joint.
