Surface processing level, characteristics and USES

The original surface: NO. 1 ( White board) To the surface of the heat treatment and pickling treatment after hot rolling. Generally used for cold rolled material, tank used in industry, chemical industry equipment, etc. , the thickness of the thicker by 2. 0MM- 8. 0MM。 Blunt: NO. 2 d after the heat treatment after cold rolling, pickling, its material is qualitative soft, the surface is silvery white luster, used for deep drawing process, such as automotive components, pipes, etc. Mist: NO. 2 b after the heat treatment after cold rolling, pickling, take the moderate of surface finishing processing of light. Because the surface is smooth, easy to grinding, make the surface more bright and wide range of USES, such as tableware, building material, etc. Used to improve mechanical properties after surface treatment, almost meet all purposes. Coarse sand: NO. 3 in 100 - The abrasive belt of grit # 120 products. Has better gloss, discontinuous coarse grain. Used for building inside and outside decoration materials, electrical appliances and kitchen equipment, etc. Fine sand: NO. 150-4 with granularity The abrasive belt of grit # 180 products. Has better gloss, discontinuous coarse grain, stripe than NO. 3. Used in bath, building inside and outside decoration materials, electrical appliances, kitchen equipment and food, etc. Abrasive belt of grit # 320: in 320, the products. Has better gloss, discontinuous coarse grain, stripe than NO. 4. Used in bath, building inside and outside decoration materials, electrical appliances, kitchen equipment and food, etc. Hair silk surface HAIRLINE: NO HL. 4 by appropriate granularity polishing abrasive belt grinding continuously generated grinding grain products ( Segment 150 - No. 320) 。 Mainly used for building decoration, elevator, the door of the building, panels, etc. Bright surface: BA bright annealing after cold rolling, and after a flat products. Excellent surface gloss, has a high reflectance. As the surface of the mirror. Used in home appliances, mirror, kitchen equipment, decorative materials, etc.
