Detailed description of the invention
In order to make the utility model the technical staff in the technical field more clearly understand the utility model, below in conjunction with accompanying drawing, by specific embodiment, technical solutions of the utility model are described in detail.
In concrete implementation process, the utility model relate to cold rolling continuous product line, and cold rolling continuous product line is divided into entrance, process section, and outlet section.
Please refer to Fig. 1 below, describe the process structure figure of cold rolling continuous product line.
Wherein, entrance comprises weld zone 1, cleaning area 2 and entry loop district 3.
Process section comprises annealed zone 4.
Outlet section contains outlet looping district 5, rolling zone 6 and last volume district 7.
Concrete, owing to being produce line continuously, therefore process section requires that band steel runs with stable speed.
For entrance, band steel does not have speed (suppose welding needs 2 minutes, so within these 2 minutes, band steel does not have the speed of service) when welding.Therefore, in order to ensure that process section can carry out smoothly, entrance is then provided with entry loop district 3, is used for file steel, for process section provides the condition of steady production.
For outlet section, band steel is when last volume district 7 shears bundling, and band steel does not have speed yet.And be with steel from annealed zone 4 out, there is stable speed.Therefore, in order to avoid the generation of accident, then outlet loop area 5 can be set between, be used for file steel, for process section provides the condition of steady production.
In Rolling production process, production line being arranged the topmost object of kink is production capacity coupling and rhythm of production problem before and after solving.
For cold rolled continuous annealing unit, be provided with as realizing quantity-produced welding machine after uncoiling, but because welding machine band steel when dropping into stops, and the time is relatively long, and annealing speed is below very fast, in order to ensure the continuous seepage of whole production line, be provided with kink in welding machine-annealing centre, and kink amount is very large, can reach km.
The Main Function of kink is to store enough band steel, make unit end to end section carrying out band steel is rolled up, shear, when welding and unload the operations such as volume, the band steel of unit middle part still can run continuously.
Please refer to Fig. 2 A-Fig. 2 B below, is the structural representation of kink.
In Fig. 2 A-Fig. 2 B, the schematic diagram having described cover and conformed to a conventional pattern.Fig. 2 A has been the schematic diagram of cover; Fig. 2 B is the schematic diagram conformed to a conventional pattern.Playing cover and conforming to a conventional pattern is all in order to can file steel better.
In actual applications, the pattern of kink has four kinds: be 1. with steel to pile the looping pit of multilayer; 2. the looping pit that steel freely dangles is with; 3. vertical looping tower; 4. Horizontal loose sleeve car.
The utility model does not limit for the pattern of kink.
Further, the interior during this period of time band steel welded due to weld zone 1 is static, and now process section then can pull from the loop area of entrance and be with steel to produce.When band steel has welded, the band steel amount that the loop area of entrance stores then can tail off.Such as, entrance loop area stores 1000 meters of band steel originally, and band steel is when weld zone 1 welds, and process section then can pull band steel from entry loop district 3.After band steel has welded, the band steel amount that likely entry loop district 3 stores only has remained 200 meters-300 meters.Therefore, after band steel has welded, then can fill cover to entry loop district 3, band steel can be filled with loop area from weld zone 1, produces to continue being supplied to process section.
Further, because band steel is at the velocity-stabilization of process section, then necessarily requires band steel from after the weld zone 1 of entrance weld, start acceleration, until speed meets the production requirement of process section.Now, if band steel accelerates too fast at entrance, then the production of process section can be affected.If band steel arrives the excessive velocities of process section, then belt steel surface cleannes can be made to meet the demands, cause furnace roller dross, cause major quality accident, and the medium such as consumption degreasing agent, defoamer that can be excessive, increase cost.In addition, also harm may be brought to entry loop district 3.Such as, if the speed being with steel to be filled with entry loop district 3 is far smaller than the speed that process section pulls from loop area, so the band steel of loop area then can be fewer and feweri, and finally cannot continue provides band steel to process section, causes the generation of production accident.If band steel is filled with the speed in entry loop district 3 far away higher than the speed that process section pulls from loop area, then band steel can be caused stacking in loop area, can cause the accident equally.Therefore, the cold rolling continuous product line that the utility model provides, has done following process at entrance, please refer to Fig. 3, is the schematic diagram of the check strap steel that provides of the utility model in the speed of entrance:
Regulation band steel is t1 in the whipping time of described weld zone 1, and it is t2 that described band steel fills the time of having overlapped in described entry loop district 2, and wherein, 5≤t1-t2≤45, unit is second.
The principle of this regulation is as follows, because band steel is when motion same distance, movement velocity and run duration be interactional (in actual applications, band steel also can be variable accelerated motion, with this understanding, movement velocity and run duration are relevant equally), therefore, to maximum speed limit, then can restrict the time, that is: welded after entrance opens car at band steel, progressively gather way, until band the steel whipping time deduct band steel fill in described entry loop district 2 cover the deadline between 5s ~ 45s time, stopping gathers way, guarantee to be with the speed of steel motion to meet the production requirement of process section with this.
For outlet section, band steel is when coiling machine bundling, and band steel does not have speed.Therefore, first can enter outlet looping district 5 from process section band steel out and store, band steel after shearing bundling, then pulls from outlet looping district 5.
But be static during band steel shearing bundling, therefore, the band steel memory space in outlet looping district 5 then can become more and more.Such as, the memory space in outlet looping district 5 is 1200 meters, and actual storage amount has been 1000 meters.
Now, then cover can be taken out to outlet looping district 5.That is: outlet looping district 5 take out cover, be then the band steel in outlet looping district 5 is pulled last volume district 7 carry out shearing bundling.If this process, the speed generation great change of band steel, then can cause strip property saltus step, cause performance inconsistency requirement.
Therefore, the cold rolling continuous product line that the utility model provides, having done following process at outlet section, specifically please refer to Fig. 4, is the schematic diagram of the strip speed of the section of restricting export that the utility model provides:
Regulation, the described band steel time that second time is sheared in described last volume district 7 is t3, and it is t4 that described band steel takes out the time of having overlapped in described outlet looping district 5, and wherein, 5≤t3-t4≤45, unit is second.
Similar with the principle of entrance herein, all the speed utilizing time check strap steel, that is: coil of strip outlet Qi Chehou is cut in outlet point, progressively gather way, until again the time of shear band steel deduct band steel outlet take out cover the deadline be between 5s ~ 45s time, stopping gathers way, and guarantees to be with the speed of steel motion to meet the production requirement of process section with this.
