Mirror aluminum sheet plate
Mirror aluminum sheet plate Time ：2022/08/19 Click ： Mirror aluminum can be obtained by electrolytic polishing, chemical polishing, mechanical polishing, rolling and calendering, etc., and the color of the product can be adjusted according to different needs, so that the appearance of the produced product is more colorful and beautiful. The mirror aluminum introduced in this article refers to the mirror effect on the surface of the strip by rolling and calendering. Such products are widely used in lamps, high-end interior architectural decoration, architectural appearance, interior and exterior decoration of automobiles, signs, nameplates and other fields , which are a branch and extension of high-surface aluminum strips. However, the mirror aluminum is prone to scratching defects in the production process, which seriously plagues the improvement of the quality of mirror products, resulting in a decline in yield and ultimately affecting economic benefits. Scratching is a surface defect that is formed after the surface of the material is damaged after being rolled by a roller, although it has no hand feeling but affects the appearance of the material surface. In this paper, the morphology, generation mechanism and solution direction of scratching defects on the surface of mirror aluminum are studied through comparative experiments, and it is expected to find a breakthrough and a solution to the problem. The test materials are 1070 and 1050 aluminum alloys, and the thicknesses of the hot-rolled coils are (7.0±0.3) mm and (3.0±0.05) mm. 1) Insufficient lubrication during hot rolling production can easily cause the surface to stick to aluminum. After repeated rolling, the defects are healed in the surface layer of the material, and the scratching defects appear after polishing. 2) Irregular hoisting and placement during coil transfer will cause damage to the surface of the coil, resulting in aluminum powder pressing into the surface during rolling, forming surface defects and healing, and surface defects appear after polishing. 3) During polishing and rolling, aluminum powder continuously enters the rolling oil. If the filtering quality is not good or the purging is not in place, the aluminum powder will be pressed into the plate surface to form fine scratches. Therefore, it is necessary to control the hot-rolled emulsion management, coil transfer, and rolling oil to reduce the probability of scratches on the mirror aluminum surface.

Research on cold rolling process of aluminum alloy sheet and strip for mirror surface
Research on cold rolling process of aluminum alloy sheet and strip for mirror surface Time ：2022/07/29 Click ： The surface brightness of mirror aluminum alloy products is close to or reaches the brightness of mirrors, the surface gloss is high, and the texture is fine. )Wait. Since this product is an aluminum alloy sheet and strip with ultra-high surface quality requirements, it is very difficult to research and develop this product. Some domestic aluminum rolling companies have also developed this product, but the effect is not satisfactory, mainly in the rough surface texture. , low gloss, and many surface quality defects. Based on the existing tooling conditions in 2012, our company used a 1400mm cold rolling mill to conduct process research on the aluminum alloy sheet and strip for 1070 aluminum alloy mirror. Through process research, the difficult problems such as poor surface brightness, rough texture, and many surface quality defects have been gradually solved, so that our company can stably produce mirror aluminum products with high surface reflectivity, and the longitudinal gloss can be stably above 780GS, and the highest 820GS, to meet the needs of the domestic market, some products can be replaced Imported mirror aluminum has broken the long-term dependence on imports of domestic high-grade mirror aluminum products, which is of great significance. At present, 1070 aluminum alloy is the main aluminum alloy sheet and strip for mirror surface rolling, supplemented by aluminum alloys such as 3 series and 8 series. This technical scheme uses 1070 aluminum alloy as the test material. A 1450mm cold roughing mill is used to produce the billet pass and intermediate pass, and a 1400mm cold finishing mill is used to produce the product pass. Under the premise that the existing equipment for producing ordinary aluminum strips remains unchanged, through the control and adjustment of the 1450mm cold roughing mill and the 1400mm cold finishing mill work roll grinding and the 1400mm cold finishing mill rolling process, the production of high brightness and high quality can be achieved.
