Description

Technical Field

[0001] The invention belongs to the technical field of hot rolling, and in particular relates to a device and a method for eliminating linear and scaly folding defects on the surface of hot-rolled stainless steel. Background Art

[0002] Defects such as scale, slag inclusions, and cracks on the surface of the steel billet have a serious impact on the quality of steel rolling and products. Therefore, the surface of the steel billet needs to be cleaned before the steel billet enters the heating furnace and after the steel billet comes out of the heating furnace. The existing device structure usually uses a multi-nozzle nozzle to clean the heated steel billet, but the high-pressure water sprayed by adjacent nozzles on the nozzle will partially overlap, causing the temperature of the steel billet to drop too quickly, resulting in uneven lateral temperature at the same position of the steel billet, affecting the quality of hot rolling.

[0003] After searching, the prior art publication number CN117124249A is a medium-high pressure abrasive descaling device and process for the surface of a continuous casting and continuous rolling steel billet; the device uses an upper coarse descaling nozzle group, an upper fine descaling nozzle group, a lower coarse descaling nozzle group, and a lower fine descaling nozzle group to spray high-pressure water mixed with a certain proportion of abrasive particles to dephosphorize the steel billet, but when a multi-nozzle nozzle is used for descaling, the high-pressure water sprayed from adjacent nozzles will overlap, causing the temperature of the steel billet at the overlapping point of the water flow to drop too quickly, causing the lateral temperature of the same position of the steel billet to be uneven, resulting in defects such as folding during the rolling process of the steel billet.

[0004] After searching, a billet surface cleaning device with a prior art announcement number of CN220329608U is found. The device uses a hydraulic rod to drive a movable scraper and a movable steel brush to fit the top of the billet body, and under the driving action of an electric push rod, the two movable steel brushes use a connecting rod to pull a sliding seat, so that the side steel brushes on the front and rear sides are in close contact with the billet body, and then cooperate with the operation of the conveying component to clean the billet; however, the device can only clean the oxide scale on the billet surface, and cannot handle defects such as cracks, scars and bubbles on the billet surface, resulting in quality defects such as folding when the billet is heated and hot rolled;

[0005] Therefore, a device and method for eliminating linear scale-like folding defects on the surface of hot-rolled stainless steel is needed, which can prevent the lateral temperature unevenness at the same position of the heated billet during the descaling process while deeply processing the unheated billet. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a device and method for eliminating linear scale-like folding defects on the surface of hot-rolled stainless steel. The present invention completes the deep treatment of unheated steel billets by cooperating with a cleaning device and a grinding device to prevent the surface defects of the steel billets from affecting the hot rolling quality; at the same time, the dephosphorization device is used to clean the oxide scale generated on the surface of the steel billet after heating to prevent the lateral temperature unevenness at the same position of the steel billet during the descaling process.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] A method for eliminating linear scale-like folding defects on the surface of hot-rolled stainless steel, specifically comprising the following steps:

[0009] 1) Surface cleaning: After the steel billet is sent into the grinding box by the transport roller, the power mechanism I in the cleaning device controls the scraper to fit the steel billet, and then the electric motor I controls the support plate I to drive the scraper to clean the oxide scale on the surface of the steel billet;

[0010] 2) Surface grinding: The transport roller then transports the steel billet to the bottom of the grinding device, and the motor II controls the grinding block to fit the surface of the steel billet. At the same time, the electric push rod III controls the mounting seat to drive the grinding block to slide back and forth along the support plate II to grind the steel billet. At the same time, the cleaning mechanism and the air intake pipe in the recovery device clean the debris generated during the grinding process into the collection mechanism for recycling;

[0011] 3) Heating: After the grinding, the steel billet enters the heating furnace for heating. While the steel billet is being heated, the power mechanism II in the dephosphorization device is controlled to drive the arc baffles I, II, III, IV and V to rotate and cover the outlet slot of the outlet pipe according to the width of the steel billet; and the electric push rod VIII is controlled to drive the sealing plate on the push rod to slide along the guide plate to the side of the arc baffles I, II, III, IV or V to close the two ends of the guide plate; after the steel billet is heated, the steel billet is transported into the descaling box by the transport roller;

[0012] 4) Descaling: High-temperature steam and water are introduced into the outlet pipe of the dephosphorization device, so that the high-temperature steam and water are sprayed out from the gap between a pair of guide plates, forming a linear water blade to clean the oxide scale produced on the surface of the heated billet. After the oxide scale is cleaned, the billet is transported to the subsequent device for hot rolling treatment.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1) The power mechanism Ⅰ in the cleaning device controls the sliding seat to drive the support plate Ⅰ to descend, so that the scraper fits the billet. Then the electric motor Ⅰ cooperates with the lead screw to control the support plate Ⅰ to drive the scraper to move back and forth along the billet surface, so that the scraper preliminarily cleans the original oxide scale on the billet surface and the slag attached to the billet surface, exposing the billet surface, making it convenient for the grinding device to grind the billet and remove defects such as cracks, scars and bubbles on the billet surface; at the same time, the disassembly and assembly mechanism Ⅰ controls the sliding rod Ⅰ and the sliding rod Ⅱ to slide back and forth along the support plate Ⅰ through the electric push rod Ⅰ and the electric push rod Ⅱ, so that the connecting rod Ⅰ and the connecting rod Ⅱ control the fixed plate to drive the pin shaft Ⅰ to insert or pull out the pin hole on the scraper, thereby realizing the rapid disassembly and installation of the scraper;

[0026] 2) The motor II in the grinding device controls the support plate II to rise or fall, thereby controlling the grinding block to adapt to the surface of the steel billet with different thicknesses; at the same time, the electric push rod III cooperates with the sliding plate to control the connecting shaft I to drive the connecting plate I and the mounting seat to slide back and forth along the supporting plate II, so that the grinding block grinds the steel billet horizontally, eliminates the surface defects of the steel billet, ensures the surface flatness of the steel billet, and facilitates subsequent processing; at the same time, the disassembly and assembly mechanism II controls the fixed block to slide in the slide groove on the connecting plate I and the mounting seat through the rotating seat and the threaded rod, so that the staff can quickly remove the mounting seat from the connecting plate I to complete the replacement of the grinding block;

[0027] 3) The recovery device uses the cleaning mechanism to clean the debris attached to the upper surface of the steel billet during the grinding process into the collection mechanism. At the same time, the industrial vacuum cleaner cooperates with the air intake pipe and the connecting pipe to suck the floating objects generated during the grinding process into the collection mechanism. Finally, the electric motor III in the collection mechanism controls the gear II to cooperate with the gear III to drive the rotating plate to rotate to cover the feed port of the dust collecting trough. Then the electric motor IV controls the spiral blade to clean the debris in the dust collecting trough into the recovery pipe through the discharge port on the rotating plate to prevent the debris from entering the heating furnace with the steel billet and then adhering to the surface of the steel billet again to form defects, resulting in quality problems such as folding during the rolling process of the steel billet.

[0028] 4) The billet heated by the heating furnace enters the descaling box, and then high-temperature steam and water are introduced into the outlet pipe of the dephosphorization device, so that the high-temperature steam and water are sprayed out from the gap between a pair of guide plates, forming a linear water blade to clean the oxide scale on the surface of the billet, preventing the high-temperature steam and water from repeatedly contacting the billet, resulting in uneven lateral temperature at the same position of the billet, causing defects such as folding during the rolling process of the billet;

[0029] 5) The power mechanism II in the dephosphorization device controls the arc baffles I, II, III, IV and V to rotate to cover the outlet slot of the outlet pipe, so that the high-temperature steam and water sprayed through the guide plate can adapt to the width of the steel billet, thereby improving the utilization efficiency of the high-temperature steam and water; at the same time, the electric push rod VIII drives the sealing plate on the push rod to slide along the guide plate to seal the two ends of the guide plate to prevent the high-temperature steam and water from escaping from the two ends of the guide plate, causing the pressure of the high-temperature steam and water to drop, affecting the effect of the high-temperature steam and water in cleaning the steel billet.
