Problems solved by technology

However, chemical methods often choose hydrochloric acid, nitric acid, hydrofluoric acid, sulfuric acid and other strong acids and toxic substances (such as hydrofluoric acid) as acid etchants to treat stainless steel. These strong acids and toxic substances will cause harm to the environment and operators. Any environmenta

Example Embodiment

[0030](Example 1)

[0031]The stainless steel sheet sub-surface treatment method of the present embodiment includes the following steps:

[0032]Step 1, produce a special roll for stainless steel sheet matt surface treatment, and specifically includes the following steps:

[0033]Step 1.1, select the titanium alloy roll, the first high-speed steel roll and the second high speed steel roll, and the high-speed steel roll and the hardness of 67 to 69 hrc are selected from the group consisting of 62 to 64 HRC.

[0034]Step 1.2, partition the titanium alloy roll, the first high speed steel roll and the second high speed steel roll, the high-speed steel roller is ground to the roughness of 0.10 to 0.15 um, surface requirements: no twill, spiral, grinding wheel traces, scratches; The titanium alloy roller is ground to a roughness of 0.12 to 0.15 um, a surface requirement: No twill, spiral, grinding wheel traces, scratches.

[0035]Step 1.3, for the polishing of the titanium alloy roll, the first high-spe...

Abstract

The invention discloses a stainless steel plate matte surface treatment method and a manufacturing method of a special roller thereof. The manufacturing method of the special roller comprises the following steps of step 1, selecting a roller; step 2, grinding the roller; step 3, performing polishing treatment on the ground roller; and step 4, performing sand blasting treatment on the polished roller. According to the manufacturing method of the special roller provided by the invention, a high-speed steel roller and a titanium alloy roller are subjected to grinding, polishing and sand blasting treatment to obtain three rollers with different roughness and specially used for treating a matte surface of a stainless steel plate, and the rollers manufactured through the method are used for conducting matte treatment on the stainless steel plate, and compared with chemical treatment, the method is safer, free of toxicity and pollution, and compared with a conventional roller, the roller has a more effective rolling surface, and the matte effect of the surface of a rolled stainless steel plate is effectively improved.

Description

technical field [0001] The invention relates to the field of matt surface treatment of stainless steel plates, in particular to a method for treating the matt surface of stainless steel plates and a method for manufacturing special rolls thereof. Background technique [0002] Due to the advantages of strong corrosion resistance and low cost, austenitic stainless steel is widely used in the medical equipment industry. In this industry, stainless steel equipment is required to be processed into matt to avoid light pollution caused by reflections of indoor lights. At present, matte treatment technology is often used to process stainless steel into a matte surface with a uniform silver-white metallic luster. [0003] Commonly used matt treatment methods are divided into mechanical methods and chemical methods. The chemical method can ensure a certain metallic luster and corrosion resistance while the metal is matte. However, chemical methods often choose hydrochloric acid, nit...
