Problems solved by technology
[0003] At present, the commonly used pickling method for stainless steel plates is spray pickling, but the inventors have found that pickling of the stainless steel plates on both sides of the surface is likely to occur after pickling using the spray pickling system in the prior art. Different degrees of pickling defects, the pickling effect is not ideal
The inventor found after further in-depth research that the spray pickling in the prior art is all horizontal pickling (that is, the stainless steel plate is placed along the horizontal direction during the spray pickling process), which causes the surface of both sides of the stainless steel plate to A major reason for the difference in the degree of pickling

The invention relates to a pickling system and method for stainless steel plates. The pickling system sequentially includes: a first turning device, a pickling assembly and a second turning device along the direction of the processing sequence. The first turning device can receive Place the stainless steel plate, and turn the stainless steel plate to be placed in a vertical direction. The pickling assembly includes a first transport mechanism connected between the first and second turning devices, and can spray pickling from above to the stainless steel plate. Liquid spraying device, the first transport mechanism can receive the stainless steel plate turned over by the first steel turning device and transport it to the second steel turning device, and the stainless steel plate placed in the vertical direction is parallel to the first transport mechanism Transport direction: the second steel turning device can receive the stainless steel plate pickled by the pickling assembly, and turn it over to be placed along the horizontal direction. Pickling the stainless steel plate by the pickling system of the present invention can prevent the occurrence of different pickling degrees on the surfaces of both sides of the stainless steel plate and ensure better pickling effect.
Description
technical field [0001] The invention belongs to the field of metal processing, and in particular relates to a pickling system and method for stainless steel plates. Background technique [0002] Stainless steel plate is widely used in the industrial field due to its superior corrosion resistance, surface aesthetics and many other advantages. The iron oxide scale produced on the surface of stainless steel during hot rolling and heat treatment will have adverse effects on subsequent processing and surface quality, and it needs to be removed in time. As pickling is an important process for removing scale in the production of stainless steel plates, the choice of pickling process will directly affect the final surface quality of stainless steel products, which has a very important guiding role in actual production. [0003] At present, the commonly used pickling method for stainless steel plates is spray pickling, but the inventors have found that pickling of the stainless stee...
