Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel hot rolling, and particularly relates to a device for controlling the side profile of a hot-rolled stainless steel slab. Background Technique

[0002] In the post-rolling cooling of hot-rolled strip production, the temperature drop rate at the strip edges is usually greater than that in the middle, making the temperature within a certain range at the strip edges lower than that in the middle. When the internal stress caused by the temperature difference reaches the yield stress of the material, plastic extension deformation occurs, and edge wave defects remain after further cooling to room temperature; thus, it affects the size of the stainless steel side profile and further affects the control of the stainless steel external dimensions.

[0003] After retrieval, a control method for eliminating the laminar cooling wave shape of thin-gauge patterned plates with the prior art publication number CN114042761A designs rolling control process parameters from four aspects: controlling air cooling, laminar water cooling, coiling temperature, and pinch roll pressure. The specific technical solution is as follows: The laminar cooling equipment is arranged as follows: 4 groups in the rough adjustment section, namely MZ1, MZ2, MZ3, and MZ4, with 8 headers in each group and a cooling length of 4.8 meters; 6 groups in the fine adjustment section. The following disadvantages exist in the treatment process: The thin-gauge patterned plates are leveled by the pinch rolls, and the cooling water remaining on the surface of the thin-gauge patterned plates will be pressed into the surface of the thin-gauge patterned plates during the leveling process, thereby forming water marks on the surface of the thin-gauge patterned plates, thus affecting the quality of the thin-gauge patterned plates.

[0004] After retrieval, a method for horizontally uniformly cooling hot-rolled low-carbon strip with the prior art publication number CN118218422A includes the following steps: S1. The low-carbon strip passes through the laminar cooling section, reducing the strip temperature to the first-stage cooling temperature while reducing the temperature difference between the middle and edges of the strip to within 15°C; S2. The low-carbon strip passes through the air mist cooling section, reducing the strip temperature to the second-stage cooling temperature while further reducing the temperature difference between the middle and edges of the strip to within 10°C; S3. The low-carbon strip passes through the water replenishment cooling section, and the cooling water is sprayed in a spray form. After the strip temperature is reduced to the appropriate coiling temperature, it is sent to the coiler for coiling. The following disadvantages exist in the treatment process: By controlling the cooling temperature and the temperature difference between the middle and edges of the strip, the edge wave defects are further controlled; however, it can only weaken the edge wave defects of the strip and cannot level the edge wave defects caused by the temperature difference still existing during the cooling process of some strips, thus affecting the quality of the strip.

The purging gas enters the hose 4043 through the air inlet pipe 4041 and the jet pipe 4042, and then is blown out to the surface of the stainless steel slab 7 through the hose 4043. Thus, the residual cooling water on the surface of the stainless steel slab 7 is blown away to prevent water marks from being generated on the surface of the stainless steel slab. The motor II 4048 drives the gear V 40481 to rotate, the gear V 40481 drives the rack 40491 to move, the rack 40491 drives the translation plate 4049 to move, the translation plate 4049 drives the trapezoidal block 4044 to move, and the trapezoidal block 4044 drives the jet pipe 4042 to move, and the spring is compressed, so that the surface of the trapezoidal block is not higher than the outer surface of the translation plate. It can prevent the trapezoidal block from scratching the surface of the stainless steel slab during the rotation of the leveling roller.

The shielding plate 305 can shield the edge of the stainless steel slab 7 to prevent the edge of the stainless steel slab 7 from cooling too fast and generating edge waves.

[0045] A device for controlling the side profile of a hot-rolled stainless steel slab operates as follows: The stainless steel slab 7 after finish rolling is transported by the transport roller 2 to the laminar cooling mechanism 3 for cooling. The cooled stainless steel slab 7 enters the purging and leveling mechanism 4. The electric push rod II 4047 provides power to drive the rotating plate 4045 to rotate. The rotating plate 4045 drives the hose 4043 to move, causing the rotating plate 4045 to rotate towards the side of the stainless steel slab 7. The purging gas enters the hose 4043 through the inlet pipe 4041 and the jet pipe 4042, and then is blown out onto the surface of the stainless steel slab 7 through the hose 4043; thereby blowing away the residual cooling water on the surface of the stainless steel slab 7 to prevent water marks from forming on the surface of the stainless steel slab. The leveling roller 401 performs overall extrusion and leveling on the stainless steel slab 7, so that the side profile of the stainless steel slab 7 can be leveled; finally, the side profile of the stainless steel slab 7 is leveled by the edge leveling mechanism 5. The upper and lower groups of pressure rollers of the stainless steel slab 7 squeeze the sides of the stainless steel slab 7 against each other, thereby achieving the effect of leveling and repairing the edges of the stainless steel slab 7; preventing edge wave defects from occurring in the stainless steel slab 7 and affecting the quality of the stainless steel.
