Production process of mirror polishing machine
Aluminum polishing is widely used and requirements are relatively high, high-grade mirror effect, which to our current mirror polishing machine polishing technology and equipment performance and automation, and configuration and material selection are required is quite high. But there is one thing we can not ignore, that is, the production and use of aluminum products, in order to achieve the desired polishing effect before polishing should pay attention to the production of aluminum molding process. Here we briefly explain the aluminum mirror polishing machine processing of the former process should pay attention to what.
Extruded ingot: extruded ingot of purity, chemical composition and internal structure of extruded light material surface quality and luster polishing brightness huge, so quality of ingot is prerequisite for aluminum material polishing.
The purity of the extruded ingot ingot purity is high, the better polishing effect of aluminum extrusion:
Ingot purity depending on the ingot metal impurities and non-metallic impurities content and metal impurities mainly refers to the Fe, Mn, Cu, Zn, Cr, Ti, ether some impurities in the most important is Fe. The effect of Fe is it will form A1 and Si primary precipitates containing, the precipitates in Al almost no solid solubility will increase on the extrusion speed sensitive surface defects, dent, tear, and the serious influence to the polished finish and brightness. Fe content of the best control below 0.1%, the United States some of the contents of the polishing plant Fe are specified in the following 0.08%. On the other hand, non metal impurities also have important effects. Especially H2 pore and AI2O3 slag inclusion. Compression in the H2 in ingot porosity and Al2O3 slag directly lead to extrusion of material surface deterioration, serious when appear white dots, mosquito foot, working with adhesion of aluminum and pits. In order to reduce the content of H2 and A1O3, in addition to the selection of good quality, high purity aluminum, try not to add the leftover material extrusion, especially oxidized scrap, in ensuring the furnace exhaust and refined at the same time, increase outside the furnace exhaust and ceramic filter, ensure the ingot in the H2 content below the 0.15ml/100g.
