Description

Technical Field

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

[0002] There are steps such as rolling and pickling in the production process of stainless steel plates. Pickling is a process of carefully cleaning the slag produced on the surface of stainless steel after annealing. During the pickling process, the slag is removed by soaking the stainless steel plate in acid solution to produce a chemical reaction with the acid solution, and then the residual acid solution is cleaned on the stainless steel plate after pickling to complete the surface quality control of the stainless steel plate. In this process, if the cleaning is not thorough, the surface quality will be poor, including defects such as patterns and acid spots formed by the residual acid solution immersion. The above defects are all caused by the residual pickling solution not being cleaned up completely, and the water evaporates after being exposed to the air, which in turn increases the acid concentration, thereby aggravating the corrosion of the stainless steel surface and causing defects such as acid spots.

[0003] After searching, the prior art publication number CN18668216A is a device for eliminating the poor surface quality of pickling of stainless steel and titanium plates and strips, which includes a box body, a squeeze assembly and a cleaning spray assembly. A cleaning chamber is provided in the box body, and a plate inlet window and a plate outlet window are respectively opened at both ends of the box body. The plate inlet window and the plate outlet window are both connected to the cleaning chamber. Two groups of squeeze assemblies are arranged at intervals in the cleaning chamber along the conveying direction of the plate and strip, and a cleaning spray assembly is arranged between the two groups of squeeze assemblies; the surface of the stainless steel plate is rinsed by the cleaning spray assembly, and then the stainless steel plate is squeezed dry by the squeeze assembly;

[0004] The above technical scheme is a conventional treatment and application means for improving the surface quality of stainless steel. The squeeze component and the spray component can only be used to rinse the residual acid on the stainless steel plate. However, if the stainless steel plate carries the acid mud in the pickling tank and other sticky impurities adhere to the stainless steel plate, and the flushing mechanism is difficult to rinse them off, the squeeze component set after the spray component will be squeezed out, which will increase its adhesion to the stainless steel surface and increase the probability of surface defects.

[0005] Further, after searching, the prior art announcement number is CN217911713U, which is an automatic cleaning device for the surface of a stainless steel plate, including a conveying frame, the conveying frame including a bottom plate, side plates are fixedly connected to both sides of the upper end of the bottom plate, conveying rollers are rotatably connected between the side plates, the upper end of the conveying frame is fixedly connected to a spray box, and a cleaning structure is arranged between the conveying frames in the spray box; the spray structure is arranged at the upper end inside the spray box and the lower end inside the conveying frame; the above method adopts the method of spraying first, then cleaning and then wiping with cotton cloth to treat the surface of the stainless steel plate, wherein the cotton cloth wiping can simultaneously wipe off the residual cleaning water and the sticky point-shaped acid mud on the surface of the stainless steel, but after using it for a period of time, the cotton cloth will reduce the adsorption of the cleaning water in order to absorb enough water, and then the cleaning liquid and the acid remaining in the cleaning liquid will remain, forming acid impregnation or acid spots. 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 pickling pattern defects on the surface of hot-rolled stainless steel.

[0021] A method for using a device for eliminating pickling pattern defects on the surface of hot-rolled stainless steel is as follows:

[0022] 1) Oxidation slag removal: First, the stainless steel plate is changed in direction at the descaling mechanism so that both sides can be cleaned of slag by the cleaning rollers on the descaling mechanism. During the cleaning process, the first motor drives the main shaft to rotate, and then drives the support arm, the insert arm, and the cleaning roller to rotate, so that the cleaning roller stops and contacts the surface of the stainless steel plate for cleaning;

[0023] 2) Replacement of cleaning roller: When there is a lot of slag on the cleaning roller, the main shaft rotates to replace the cleaning roller; the main shaft drives the cleaning roller to rotate, and then drives the cleaning roller to the bracket. During this process, the push rod on the support arm is gradually pushed under the control of the guide plate and the limit plate, and the plug block is pushed out of the installation slot, thereby releasing the connection and fixation between the support arm and the plug arm, so that the two are ready for separation; when passing through the arc arm on the bracket, the cleaning roller slides along the arc arm to separate the plug arm from the support arm to complete the removal of the cleaning roller; then continue to rotate the main shaft to align the support arm with the first fixed arm to prepare for the plug arm on the cleaning roller to connect with the support arm;

[0024] 3) Installation of cleaning roller: The cleaning roller in the loading box descends by its own weight and is supported by the first fixed arm. The insertion arm can be kept horizontal by the cooperation of the third limit plate and the flat mouth, and then the limit groove is accurately matched with the sliding arm, thereby ensuring that the insertion arm and the support arm can be smoothly aligned and plugged in; when the insertion arm is plugged into the support arm, the end of the insertion arm is plugged into the slot; then the push block is pushed by the push mechanism, so that the push plate on the push block pushes the cleaning roller to move along the sliding arm to plug the support arm. When the push block retreats and resets, the push plate rotates under the obstruction of the cleaning roller and presses the arc arm into the arc groove. After passing over the cleaning roller, the arc arm pushes the push plate to reset under the push of the second spring, and the cleaning roller is pushed back and forth in this way;

[0025] At this time, the insert block is pushed through the inclined slot and then retreats into the empty slot, and then is pushed out again at the installation slot by the first spring and pushes the push rod to be pushed out synchronously so that the insert arm and the support arm are fixed and connected;

[0026] 4) Pickling of stainless steel plates: The stainless steel plates are transported into the pickling tank and pickled with acid;

[0027] 5) Squeezing treatment by the squeezing mechanism: After pickling, the stainless steel plate passes through the squeezing roller of the squeezing mechanism for squeezing and liquid clearing treatment;

[0028] 6) Flushing of stainless steel plates: The water tank in the flushing mechanism supplies water to the water pipes and nozzles on the fixed seat to flush the stainless steel surface and remove the residual liquid after pickling. During the flushing process, the third motor can drive the screw in the adjustment component to rotate to move the fixed seat and the nozzle, so as to achieve relative concentration and dispersion of the nozzles according to the width of the stainless steel plate, which is conducive to improving the flushing effect.

[0029] 7) Scrubbing the surface of the stainless steel plate: After rinsing, the surface of the stainless steel plate is scrubbed with a scrubbing mechanism, which can not only remove the rinsing water, but also use the felt cloth to wipe off the debris attached to the surface that cannot be washed off; during the scrubbing process, the fourth motor drives the chain to rotate, thereby driving the chain plate and the felt cloth to circulate and rotate on both sides of the stainless steel plate for wiping; the felt cloth is further squeezed by the squeezing mechanism to remove the water in the felt cloth so that it remains dry to a certain extent, which is beneficial to improving the wiping effect; the third spring pushes the first pressure roller to cooperate with the second pressure roller to squeeze and remove water from the felt cloth on the chain plate; after the above treatment is completed, the stainless steel plate is transmitted out of the box.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1) The descaling mechanism can realize the pretreatment of slag before the stainless steel enters the pickling, which reduces the work intensity of pickling and improves the efficiency and quality of pickling in disguise; further, the flushing mechanism and the scrubbing mechanism can quickly rinse and wipe the residual pickling liquid on the surface of the stainless steel after pickling, and at the same time, the squeeze mechanism can maintain the dryness and water absorption of the felt cloth in the scrubbing mechanism, ensuring that the flushing water can be scrubbed and absorbed at all times.

[0032] 2) A felt cloth is provided in the scrubbing mechanism. After the stainless steel plate is rinsed, the scrubbing mechanism is used to scrub the surface of the stainless steel plate, which can not only remove the rinsing water, but also use the felt cloth to scrub away the acid mud attached to the surface that cannot be rinsed away; during the scrubbing process, the fourth motor drives the chain to rotate, thereby driving the chain plate and the felt cloth to circulate and rotate on both sides of the stainless steel plate to wipe, and the scrubbing state can be maintained at all times; further, the felt cloth is squeezed and removed of water by the squeezing mechanism to keep it dry and water-absorbent to a certain extent, which is conducive to improving the wiping effect, wherein the third spring pushes the first pressing roller to cooperate with the second pressing roller to achieve the squeezing and water removal effect of the felt cloth on the chain plate, thereby achieving the purpose of maintaining water absorption;

[0033] 3) In this scheme, a dephosphorization mechanism is provided, and the cleaning roller is controlled by the control mechanism to clean the slag on the surface of the stainless steel in real time. The cleaning roller is attached to the stainless steel plate and driven by the transmitted stainless steel plate to rotate to realize the cleaning work; further, when the cleaning roller needs to be replaced, the cleaning roller can be automatically replaced by the pushing mechanism in cooperation with the control mechanism, the bracket and the loading box, which greatly improves the replacement efficiency; wherein the control mechanism controls the rotation of the main shaft to rotate the cleaning roller to the bracket. During this process, the push rod on the support arm is gradually pushed under the control of the guide plate and the limit plate to push the plug block out of the installation groove, thereby releasing the connection and fixation between the support arm and the plug arm, so that the two can be quickly separated; when rotating and passing through the arc arm on the bracket, after the cleaning roller rotates to the bracket, it is first supported and restricted by the arc arm as it continues to rotate, and then the cleaning roller slides along the arc arm as the main shaft continues to rotate, and while descending, the plug arm of the cleaning roller can continuously escape from the support arm to realize the effect of automatic disassembly.

When the push block retreats and resets, the push plate 175 rotates under the obstruction of the cleaning roller 13 and presses the arc-shaped arm 176 to push into the arc-shaped groove 1721. After passing over the cleaning roller 13, the arc-shaped arm 176 pushes the push plate 175 to reset under the push of the second spring 177, and the cleaning roller 13 is pushed back and forth in this way;

[0071] At this time, the insert block 1312 is pushed by the inclined slot 1221 and then retreats into the empty slot 1313, and then is pushed out again at the installation slot 1223 by the first spring 1314 and pushes the push rod 125 to be pushed out synchronously so that the insert arm 131 and the support arm 122 are fixed and connected;

[0072] 4) Pickling of stainless steel plate: the stainless steel plate 6 is transferred into the pickling chamber 205 and pickled by acid solution;

[0073] 5) Squeezing treatment by the squeezing mechanism: After pickling, the stainless steel plate 6 passes through the squeezing roller 32 of the squeezing mechanism 3 for squeezing and liquid clearing treatment;

[0074] 6) Flushing of stainless steel plate: the water tank 42 in the flushing mechanism 4 supplies water to the water pipe 432 and the nozzle 431 on the fixed seat 43, flushes the stainless steel surface, and removes the residual liquid after pickling; during the flushing process, the third motor 41 can drive the screw rod 441 in the adjustment component 44 to rotate so that the fixed seat 43 and the nozzle 431 can be moved, and the nozzle 431 can be relatively concentrated and dispersed according to the width of the stainless steel plate 6, which is conducive to improving the flushing effect;

[0075] 7) Scrubbing the surface of the stainless steel plate: After rinsing, the scrubbing mechanism 5 is used to scrub the surface of the stainless steel plate 6, which can not only remove the rinsing water, but also use the felt cloth 531 to scrub away the debris attached to the surface that cannot be washed away; during the scrubbing process, the fourth motor 51 drives the chain 52 to rotate, thereby driving the chain plate 53 and the felt cloth 531 to circulate and rotate on both sides of the stainless steel plate 6 for wiping; further, the felt cloth 531 is squeezed and removed by the squeezing mechanism 54 to remove the water in the felt cloth 531 so that it can maintain a certain degree of dryness, which is conducive to improving the wiping effect; the third spring 544 pushes the first pressing roller 543 to cooperate with the second pressing roller 545 to squeeze and remove water from the felt cloth 531 on the chain plate 53; after the above treatment is completed, the stainless steel plate 6 is transmitted out of the box 2.
