Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel plate surface treatment, in particular to a production device for ultra-pure ferrite stainless steel plates. Background Art

[0002] The production and processing of stainless steel includes steps such as billet heating, rolling, annealing, descaling, and pickling. After annealing, the scale on the surface of the stainless steel plate is removed by descaling, and then pickling is performed. However, after shot blasting, there is still residual scale on the stainless steel plate, which will increase the burden of the pickling process. Therefore, further surface treatment of the stainless steel plate is performed in advance before the stainless steel plate enters the pickling process.

[0003] First, the surface treatment technology of stainless steel plates is retrieved from the prior art; a stainless steel plate polishing line with publication number CN216298955U includes a conveying line, a plurality of transmission rollers for conveying steel plates are arranged between the two side brackets, a plurality of first clamping rollers and a second clamping roller are respectively arranged on the sides of the steel plates corresponding to the brackets, the clamping plate is provided with a pneumatic cylinder for moving the clamping plate toward the steel plates, a plurality of surface treatment rollers are arranged above the conveying line, the surface treatment rollers are provided with spiral grooves, and a polishing layer is fixed on the corresponding surface of the surface treatment rollers; the conveying line is provided with a transmission roller for driving the steel plate forward, and a clamping roller for clamping and stabilizing the steel plate is also provided. When the steel plate moves to the lower side of the surface treatment roller, under the clamping action of the clamping roller, the rotation of the surface treatment roller will not cause the steel plate to be displaced, thereby improving the effect of the surface treatment roller grinding surface force, and at the same time, the second clamping roller has a scale adjustable function, and the optimal force for clamping the steel plate can be adjusted according to the width of the steel plate;

[0004] If the above scheme is used for the surface treatment of stainless steel plates before pickling, its obvious disadvantage is that the waste generated by the surface treatment is not effectively and timely treated. The increase of waste generated by the treatment will affect the treatment of the stainless steel surface. In severe cases, relative friction will cause scratches, which will not only fail to achieve the surface treatment effect of the residual oxide scale on the surface of the stainless steel plate, but also cause product surface quality problems;

[0005] Through further retrieval, the publication number CN216859332U is a polishing machine for surface treatment of stainless steel plates. The polishing machine is provided with a slide rail, an electric wheel, a support frame, a first box body and a second box body to work together. The electric wheel at the bottom of the support frame is used to move in the slide groove in the slide rail, so that the support frame can move in a horizontal direction, which is convenient for all-round treatment of the surface of the stainless steel plate. The polishing shaft is adjusted by the gears in the first box body and the second box body. The two sets of polishing shafts can polish stainless steel plates of different thicknesses while performing two-sided polishing, and there is no need to adjust the position of the stainless steel plate. This solves the problem that most existing polishing machines for surface treatment of stainless steel plates can only polish one side at the same time. When two-sided polishing is required, one side can be polished before the other side is processed, which has low work efficiency and wastes time. In addition, the temperature of the stainless steel plate is too high after polishing one side, and it is very inconvenient to turn over and change sides, which easily leads to safety hazards. The polishing efficiency is improved, time is saved, and the operation is more convenient and manpower is saved.

[0006] If this solution is used for further surface treatment of stainless steel plates before pickling, the same disadvantage exists that the above-mentioned surface treatment waste is not handled in time;

[0007] Therefore, a surface treatment device is needed to process or remove the waste chips generated during the second surface treatment process, to ensure smooth surface treatment, and to prevent the waste chips from rubbing against the stainless steel during the treatment process, thereby causing scratches.

[0022] Compared with the prior art, the utility model has the following beneficial effects:

[0023] 1) In this scheme, a pair of surface treatment rollers are provided and arranged on both sides of the stainless steel plate to perform surface grinding treatment on both sides of the stainless steel at the same time, thereby improving the surface treatment efficiency; at the same time, one of the first grinding part and the second grinding part on the roller body can be selected for surface grinding treatment according to the original roughness and residual oxide scale degree of the stainless steel surface.
