Description

Technical Field

[0001] The present application relates to the technical field of cold-rolled steel plate annealing, leveling and oxidation barrier, and in particular to a high-quality stainless steel cold-rolled steel plate annealing, leveling and oxidation barrier device. Background Art

[0002] In the production process of cold-rolled steel sheets, annealing and leveling are two important process steps. Annealing refers to a process operation in which steel is heated to a certain temperature, kept warm, and then slowly cooled. The main purpose of annealing is to reduce the hardness of steel, eliminate cold work hardening, improve the performance of steel, restore the plastic deformation ability of steel; eliminate residual internal stress in steel, stabilize the organization, prevent deformation; and make the organization and chemical composition of steel uniform. Leveling is the process of leveling the steel plate. Specifically, hot rolling leveling refers to the method of leveling the thick steel plate by roller rolling on a hot rolling mill after heating it. The principle is to use the plasticity of the steel plate under high temperature to enhance the thickness and correct the unevenness through roller rolling. Cold rolling leveling refers to the method of leveling the thick steel plate by rolling it on a cold rolling mill after cold pressing. The principle is to use the elastic deformation characteristics of the steel plate to achieve plastic deformation of the steel plate under cold pressing, and then achieve the flatness of the steel plate through roller rolling on a rolling mill.

[0003] However, in actual production, the two steps of annealing and leveling are usually carried out in an open environment, which makes the surface of the steel plate easily react with oxygen in the air to form an oxide layer, affecting the quality and performance of the steel plate.

[0004] At present, in order to prevent the steel plate from oxidizing during the annealing and leveling process, the method of introducing protective gas into the equipment is usually adopted. However, this measure faces challenges when the steel plate needs to be transferred between the annealing chamber and the leveling chamber. Because during the transfer process, it is necessary to consider how to effectively fill or extract these protective gases to ensure that the steel plate is always in an oxygen-free or low-oxygen environment to prevent it from contacting with oxygen in the air and oxidizing. This process not only increases the complexity of the operation, but may also affect production efficiency and product quality. Utility Model Content

[0038] In addition, the detection component includes an air pressure sensor 14 fixedly connected to the inner top of the base 1, and an oxygen concentration sensor 15 is fixedly connected to the inner top of the base 1, and a controller 16 is fixedly connected to the outer side of the base 1. The controller 16 is electrically connected to the air pressure sensor 14, the oxygen concentration sensor 15, the ventilation pump 1 17, and the ventilation pump 2 18.

[0039] When in use, first open the door panel 11 around the hinge axis, place the steel plate to be processed on the top of the processing table 7, and then close the door panel 11, so that the interior of the annealing chamber 2 and the correction chamber 3 is in a closed state, then set the oxygen concentration sensor 15 to detect the oxygen concentration inside the annealing chamber 2 and the correction chamber 3, and transmit the detection data to the controller 16, and then start the ventilation pump 18 according to the preset value to cooperate with the air guide pipe 19 to extract the oxygen inside the annealing chamber 2 and the correction chamber 3. When the oxygen concentration inside the base 1 reaches the preset value detected by the oxygen concentration sensor 15, the oxygen inside the base 1 is pumped out. When the value is set, the ventilation pump 18 is turned off and the ventilation pump 1 is turned on, so that the ventilation pump 17 fills the inert gas stored in the air chamber 10 into the annealing chamber 2 and the correction chamber 3, and the air pressure sensor 14 is set to sense the air pressure inside the annealing chamber 2 and the correction chamber 3.

At this time, the interior of the annealing chamber 2 and the correction chamber 3 is in a state of low oxygen content and high inert gas;

[0040] Then, the transfer motor 9 is started to drive the transfer screw 8 to rotate, and the transfer screw 8 is threadedly connected to the transfer slider 6, and the transfer slider 6 pushes the processing table 7 to drive the steel plate to move back and forth inside the annealing chamber 2 and the correction chamber 3 along the length direction of the transfer slide 5.

[0042] When in use, when the ventilation pump 18 is started to input air into or extract air from the annealing chamber 2 and the correction chamber 3 through the air duct 19, the gas is evenly input into multiple corners of the annealing chamber 2 and the correction chamber 3 along the inside of the air duct 19 through the inside of multiple gas distribution pipes 20, thereby improving the uniformity of gas distribution inside the annealing chamber 2 and the correction chamber 3.

[0043] Reference Figure 4 and Figure 5 A sealing groove 21 is provided at one end of the annealing chamber 2 and the correction chamber 3, a rubber sealing pad 22 is fixedly connected inside the sealing groove 21, and a locking assembly is installed at one end of the door panel 11;

[0044] Among them, the locking assembly includes a locking screw 23 hinged at one end of the door panel 11, one end of the locking screw 23 is threadedly connected to a locking nut 24, a locking slot 25 is provided on one side of the base 1, and one end of the locking screw 23 is embedded in the locking slot 25.

[0045] During use, when the two door panels 11 are rotated around the hinge axis to form a closed cover on one end of the annealing chamber 2 and the correction chamber 3 respectively, the door panel 11 pushes the rubber sealing gasket 22 to embed into the interior of the sealing groove 21, and then the locking screw 23 is rotated to embed into the interior of the locking slot 25, and by tightening the locking nut 24, the locking nut 24 forms a tight contact with the base 1 along the length direction of the locking screw 23, and at the same time, the door panel 11 pushes the rubber sealing gasket 22 to deform under force and fill the interior of the sealing groove 21, thereby effectively improving the sealing effect between the door panel 11 and the annealing chamber 2 and the correction chamber 3.

[0046] Reference Figure 2 and Figure 4 The inner sides of the annealing chamber 2 and the correction chamber 3 are fixedly connected with heat insulating rock wool 26 .

[0047] During use, when annealing and leveling operations are performed inside the annealing chamber 2 and the correction chamber 3, the heat inside the annealing chamber 2 and the correction chamber 3 is wrapped by the insulating rock wool 26, which effectively reduces the temperature exchange between the inside and outside of the base 1 and improves the thermal insulation effect of the device.

[0048] The implementation principle of the annealing and leveling oxidation barrier device for high-quality stainless steel cold-rolled steel plates in this embodiment is as follows: first, the door panel 11 is opened around the hinge axis, and the steel plate to be processed is placed on the top of the processing table 7, and then the door panel 11 is closed, so that the door panel 11 pushes the rubber sealing gasket 22 to be embedded in the sealing groove 21, and then the locking screw 23 is rotated to be embedded in the locking card slot 25, and the locking nut 24 is tightened to form a tight contact with the base 1 along the length direction of the locking screw 23, and at the same time, the door panel 11 pushes the rubber sealing gasket 22 to deform under force and fill the inside of the sealing groove 21, and at the same time, the inside of the annealing chamber 2 and the correction chamber 3 are in a closed state;

[0049] Then, an oxygen concentration sensor 15 is set to detect the oxygen concentration inside the annealing chamber 2 and the correction chamber 3, and the detection data is transmitted to the controller 16. Then, according to the preset value, the ventilation pump 2 18 is started to cooperate with the air guide pipe 19 to extract the oxygen inside the annealing chamber 2 and the correction chamber 3. When the oxygen concentration inside the base station 1 reaches the predetermined value detected by the oxygen concentration sensor 15, the ventilation pump 2 18 is turned off and the ventilation pump 1 17 is turned on, so that the ventilation pump 1 17 fills the inert gas stored in the air chamber 10 into the annealing chamber 2 and the correction chamber 3, and the air pressure sensor 14 is set to sense the air pressure inside the annealing chamber 2 and the correction chamber 3. When the air pressure inside the annealing chamber 2 and the correction chamber 3 reaches the predetermined value, the air pressure sensor 14 transmits the sensing signal to the controller 16, and the controller 16 controls the ventilation pump 17 to be turned off. At this time, the interior of the annealing chamber 2 and the correction chamber 3 is in a state of low oxygen content and high inert gas.

[0050] Then, the transfer motor 9 is started to drive the transfer screw 8 to rotate, and the transfer screw 8 is threadedly connected to the transfer slider 6. At the same time, the transfer slider 6 pushes the processing table 7 to drive the steel plate to move back and forth inside the annealing chamber 2 and the correction chamber 3 along the length direction of the transfer chute 5. At the same time, the transfer slider 6 drives the corrugated folding cover 12 to stretch or fold and contract along the length direction of the synchronous chute 13, and the corrugated folding cover 12 covers the bottom of the transfer chute 5.
