Specific embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
The embodiments of the present invention disclose a kind of air-cooled section of cooling means of annealing furnace, and the method includes by air-cooled section point
At multiple along the cooling unit successively arranged with direction is passed, each cooling unit is equipped with independent cooling wind air-supply system
System further includes at least one pumping outlet system of air, at least one is located at the cooling wind for passing the cooling unit with direction rear end
Be admitted to as new cooling wind at least one cooling unit of the cooling unit front end after cooling unit outflow, it is described out
Wind system 4 is used for other cooling unit air drafts in addition to the cooling unit.
Stainless steel belt, by being heated at high temperature, is transmitted to air-cooled section in annealing furnace bringing-up section.In air-cooled section, steel band is kept
Certain speed passes to the other end from one end of cooling section, and during transmission, which is divided into multiple mutually connected
Logical cooling unit, each cooling unit substantially have no apparent demarcations, only formal separation.These coolings are single
The various wind directions for forming a system of member, for the cooling steel band at the fragment position.It is understood that steel band starts certainly
Temperature highest more arrives the steel band of section below after the cooling of cooling unit one by one step by step when into cooling section, surface
Temperature is lower.Therefore, after to steel band cooling effect, outflow cools down cooling wind in the cooling unit in position rearward
These cooling wind temperature are not high when unit, and in previous cooling technology, these wind can come out cold with front end cooling unit
But wind is drained together, and in the utility model, these above-mentioned cooling winds are passed into again in the cooling unit of front end, such one
Come, the cooling unit intake of front end is big, improves front end cooling unit to the cooling efficiency and effect of steel band, then forms connection
Dynamic effect, so as to correspond to steel band locating for cooling unit lower than previous temperature for rear end, so that the cooling effect of return air be made to reinforce.
Not only in this, since the cooling wind of rear end is discharged into the cooling unit of front end by the utility model, compared with previous cooling section, at this
Cooling unit can not have to that outlet system of air is arranged again, so that air-cooled section of annealing furnace of cooling system structure is more simplified.
It is spread out of including at least the cooling wind for passing a cooling unit with direction rearmost end is located at from the cooling unit
It is admitted to be located at as new cooling wind afterwards and passes a cooling unit with direction front end.It is understood that rearmost end
The cooling wind service efficiency of cooling unit discharge is minimum, and temperature is minimum, and the temperature of steel strips at the cooling unit of front end is most
Height is acted on the steel band at the highest cooling unit of front end temperature with the minimum return air cooling wind of temperature, to the cold of return air
But utilization efficiency highest, energy saving effect are best.
This is admitted to as new cooling wind after having the cooling wind of multiple cooling units to spread out of from the cooling unit
When at least one cooling unit of cooling unit front end, the cooling wind of multiple cooling unit outflows is sent again after pooling at one
Enter other cooling units.Specifically, the cooling wind come out after being utilized due to the cooling unit by rear end is generally all than forward
The cooling wind that the cooling unit at end comes out, theoretically, any one wind for leaning on the cooling unit of rear end to come out can be forward
The cooling unit at end utilizes again, but for utilization efficiency and comprehensively considering using cost, can't be to all cold
But the cooling wind of unit discharge all utilizes again, and general 2/5 or so the cooling for accounting for sum that can only choose by rearmost position
The wind of unit carries out secondary recycling.This when, the return air for the multiple cooling units being recycled not are an a pair
It is discharged into answering in the cooling unit of the corresponding number of front end, but the return air of these recyclings is i.e. mixed during passback
It closes, makes to complete heat exchange in mixing passback process, when being then discharged into one or more cooling units for leaning on front end respectively, return
Wind is substantially at same temperature, can arbitrarily be discharged into these cooling units, discharges without wind class, avoids system caused by grouping
Structure is complicated changes.
In the embodiment of this method, the cooling airflow in each cooling unit is mutually perpendicular to biography band direction.
The cooling unit by outlet system of air air draft is each provided with independent outlet system of air, alternatively, described arrange by outlet system of air
The cooling unit of wind shares an outlet system of air between any two.
Referring to shown in attached drawing 1-2, a kind of air-cooled section of cooling means of above-mentioned annealing furnace is also disclosed in the embodiments of the present invention
Cooling system, including cooling section main body, the cooling section main body is by multiple cooling units 1 along passing band direction successively arrangement group
At each cooling unit 1 is equipped with independent cooling wind supply air system 3, further includes pumping outlet system of air 4 and air-returning device
2, described 2 one end of air-returning device connects at least one and is located at the cooling unit 1 of the biography with direction rear end, and the air-returning device
2 other ends connect at least one cooling unit 1 of 1 front end of cooling unit, and the outlet system of air 4 connects the air-cooled section of main body
For to other 1 air drafts of cooling unit in addition to the cooling unit 1.
It is understood that the cooling wind that the cooling unit 1 by rear end is discharged needs return air secondary use,
It is to be transmitted in the cooling unit 1 of its front end by air-returning device 2, the outlet system of air 4 to those for not returned
Outlet air efficiency is used and accelerated when 1 outlet air of cooling unit that wind utilizes, in general, the outlet system of air 4 is by wind pipe and one
A induced draft fans composition.
2 one end of air-returning device connection, which is located at, passes the cooling unit 1 with direction rearmost end, and the air-returning device
The connection of 2 other ends, which is located at, passes the cooling unit 1 with direction front end.
The cooling unit 1 is equipped with 10, the connection of described 2 one end of air-returning device be located at pass with direction rearmost end the 8th,
9th, the tenth cooling unit 1, and 2 other end of the air-returning device connection be located at pass with direction front end first, second,
Third, the 4th cooling unit 1.
The air-returning device 2 include backwind tube, one end of the backwind tube set there are three diverge air inlet connector, the other end
If the air inlet connector of three forks is cooling single with described eight, the 9th, the tenth respectively there are four the outlet air connector to diverge
Member 1 connects, and the outlet air connector of four forks is connect with first, second, third, fourth cooling unit 1 respectively.
