Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention relates to a stainless steel wide and thick plate coil thermal annealing and pickling method, which comprises the following steps: uncoiling an inlet of a stainless steel wide and thick plate coil 100, welding, continuously annealing, descaling, shot blasting, pickling, flattening and coiling an outlet, and sequentially conveying the stainless steel wide and thick plate coil 100 to be processed through a conveying mechanism in each step and between adjacent steps.
Because the stainless steel wide and thick plate coil hot annealing and pickling production line is used for continuously annealing and pickling the stainless steel wide and thick plate coil 100, the stainless steel wide and thick plate coil 100 of one coil is uncoiled and unfolded, then is welded into a continuous wide and thick plate coil, and then is rotated on the production line for continuous processing operation. After the thermal annealing and pickling operation is completed, the stainless steel wide and thick plate coil 100 is cut along the welding seam through an outlet curling operation to form independent wide and thick plate coils.
As shown in fig. 1 and 4, in the exit curling step, the transfer mechanism includes a steering roller 1 and a tension roller 2 disposed in tandem.
In the exit curling step, the stainless steel wide and thick sheet roll 100 is processed using an exit device. The outlet device comprises a first device 3 located between the tension roller 2 and the turning roller 1 and a second device 4 located in front of the turning roller 1. The first apparatus 3 comprises an inspection mechanism 6, a shearing mechanism 5 and a bending machine 7 arranged from back to front. The inspection mechanism 6 is used for inspecting the surface condition of the stainless steel wide and thick plate. The shearing mechanism 5 is used for shearing the stainless steel wide and thick plate coil 100, separating the stainless steel wide and thick plate coil 100 into a plurality of independent stainless steel wide and thick plates, and removing welding seams on the stainless steel wide and thick plates.
Said second apparatus 4 comprises a coiler. The coiling machine is used for coiling the stainless steel wide and thick plate separated by the shearing mechanism 5 into a coiled structure.
The tension roller 2 rotates to feed out the stainless steel wide and thick sheet roll 100. Due to the position arrangement of the tension roller 2, the stainless steel wide and thick plate roll 100 passing through the tension roller 2 will form internal stress under the action of the bending of the tension roller 2, and has a tendency of bending upwards. The turning roll 1 is rotated to bend the stainless steel wide and thick sheet coil 100 downward and feed it into the coiler.
The exit crimping step includes:
1) the stainless steel wide and thick sheet roll 100 is pushed forward by a transport mechanism. The head of the stainless steel wide and thick plate roll 100 sequentially passes through a tension roller 1, an inspection mechanism 6, a shearing mechanism 5, a bending machine 7 and a steering roller 1. When the head of the stainless steel wide and thick plate roll 100 penetrates out of the turning roller 1 by a set first length, the conveying mechanism stops, and the first length is 40cm-50 cm. The turn roll 1 bends the head of the stainless steel wide and thick sheet roll 100 downward.
2) And the motor of the conveying mechanism rotates reversely, the stainless steel wide and thick plate roll 100 is retracted through the conveying mechanism, the stainless steel wide and thick plate roll 100 moves backwards, the stainless steel wide and thick plate roll 100 is cut at the welding seam to form a front plate and a rear plate, and the front plate is positioned in front of the rear plate. Specifically, the method comprises the following steps:
2.1) the transmission mechanism runs in reverse direction and the transmission mechanism runs in a motor inching mode. The conveying mechanism drives the stainless steel wide and thick plate roll 100 to retreat backwards. When the welding seam of the stainless steel wide and thick plate roll 100 is retreated to the front of the knife edge of the shearing mechanism 5 and is separated from the knife edge by a second length, the conveying mechanism is stopped. The shearing mechanism 5 is used for shearing the stainless steel wide and thick plate roll 100 for the first time along the length direction thereof to be divided into a front plate and a rear plate, wherein the second length is 5cm-20cm, and the welding seam is on the front plate at the moment.
2.2) continuing to retreat the stainless steel wide and thick plate coil 100 backwards, and stopping the conveying mechanism when the welding seam of the stainless steel wide and thick plate coil 100 retreats behind the knife edge of the shearing mechanism 5 and is a third length away from the knife edge. And the shearing mechanism 5 carries out secondary shearing to shear the welding seam from the front plate so as to separate the welding seam from the front plate. The third length is 5cm-20 cm. The cut-off weld seam strip is then removed from the transport device. Thus, the tail portion of the front plate and the head portion of the rear plate are formed along the weld cut. The head and the tail of the front plate are kept flat and do not tilt upwards any more, and meanwhile, the head of the rear plate is also kept flat.
3) The front plate and the rear plate are continuously pushed forwards, the front plate can normally feed the steel strip into subsequent equipment without external force action such as treading, prying and the like, the subsequent treatment of the steel strip is sequentially carried out, the steel strip sequentially passes through the first equipment 3 and the steering roller 1 and enters the second equipment 4 for subsequent treatment;
4) the back plate is operated in sequence from the exit curling step 1) to the exit curling step 3).
By the above-mentioned hot annealing and pickling method for the stainless wide and thick sheet coil, the problem that the head and tail of the stainless wide and thick sheet coil 100 after being sheared are tilted due to the winding of the tension roller 2 when the stainless wide and thick sheet coil 100 is subjected to hot annealing and pickling is solved. Under the effect of turning under the directive roller 1, the stainless steel wide and thick plate roll 100 downwarping that the directive roller 1 will pass through eliminates the upwarp deformation of the head and the afterbody of stainless steel wide and thick plate roll 100, makes the stainless steel wide and thick plate roll 100 after shearing need not just can penetrate subsequent processing equipment smoothly with the help of if stepping on pressure, external force such as sled pressure, not only convenient production, greatly reduced the potential safety hazard in addition, guaranteed operator's operation safety.
The principle and the implementation mode of the invention are explained by applying specific embodiments in the invention, and the description of the embodiments is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
