Description

Technical Field

[0001] The utility model belongs to the technical field of hot rolling, in particular to a device 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 billet surface have a serious impact on the quality of rolled steel and finished products. Therefore, the billet surface needs to be cleaned before and after it enters the heating furnace. Existing equipment typically uses a multi-nozzle nozzle to clean the heated billet. However, the high-pressure water sprayed from adjacent nozzles on the nozzle will partially overlap, causing the billet temperature to drop too quickly. This results in uneven lateral temperature at the same location on the billet, affecting the quality of hot rolling.

[0003] After searching, the prior art publication number CN117124249A is a medium- and high-pressure abrasive descaling device and process for the surface of continuous casting and rolling steel billets; 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 abrasives to dephosphorize the steel billets. However, when using a multi-nozzle nozzle for descaling, the high-pressure water sprayed by 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 prior art publication number CN220329608U revealed a billet surface cleaning device. This device uses a hydraulic rod to drive a movable scraper and a movable steel brush to fit the top of the billet body. Driven by an electric push rod, the two movable steel brushes use a connecting rod to pull a sliding seat, so that the front and rear side steel brushes are in close contact with the billet body, thereby cooperating with the operation of the conveyor assembly to clean the billet. However, this device can only remove the oxide scale on the billet surface and cannot treat defects such as cracks, scars, and bubbles on the billet surface. This can result in quality defects such as folding of the billet after heating and hot rolling.

[0005] Therefore, a device is needed to eliminate linear scale-like folding defects on the surface of hot-rolled stainless steel, which can prevent the horizontal temperature unevenness of the same position of the heated steel billet during the descaling process while performing deep processing on the unheated steel billet. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a device for eliminating linear scale-like folding defects on the surface of hot-rolled stainless steel.

At the same time, the dephosphorization device is used to clean the oxide scale generated on the surface of the steel billet after heating, thereby preventing the phenomenon of uneven transverse temperature at the same position of the steel billet during the descaling process.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 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 and slag attached to the billet surface, exposing the billet surface, making it easier 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 rods I and II to slide back and forth along the support plate I through the electric push rods I and II, so that the connecting rods I and II control the fixed plate to drive the pin shaft I to insert or pull out of the pin hole on the scraper, thereby realizing the rapid disassembly and installation of the scraper.

[0021] 2) Motor II in the grinding device controls the rise or fall of support plate II, thereby controlling the grinding block to adapt to the surface of steel billets of 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 support plate II, so that the grinding block grinds the steel billet horizontally, eliminating surface defects of the steel billet, ensuring the surface flatness of the steel billet, and facilitating subsequent processing; at the same time, the disassembly and assembly mechanism II cooperates with the rotating seat and the threaded rod to control the fixed block to slide in the slide groove on the connecting plate I and the mounting seat, so that the staff can quickly remove the mounting seat from the connecting plate I to complete the replacement of the grinding block;

[0022] 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 block 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.

[0023] 4) After being heated in the heating furnace, the billet enters the descaling box. 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. This prevents 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;

[0024] 5) The power mechanism II in the dephosphorization device controls the arc baffles I, II, III, IV, and V to rotate and block 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, preventing the high-temperature steam and water from escaping from both ends of the guide plate, causing the high-temperature steam and water pressure to drop, and affecting the effect of the high-temperature steam and water in cleaning the steel billet.
