提高金属铝熔体的纯洁度是保证加工产品质量的基础。采用玻璃丝布过滤铝熔体,是一种成本低廉,使用方便,有较好效果的工艺方法。通常是将玻璃丝布滤网安放在铸造作业线上金属液流的落差处,以及铸造流盘和结晶器的金属液穴里,实行多次拦挡过滤。对有的重要制品,还配合其它净化手段,如刚玉管微孔过滤和过流连续精炼等联合使用,以清除铝液中的夹杂和气体。玻璃丝布过滤铝熔体在国外已有几十年的历史,
Improve the purity of aluminum melt is to ensure the quality of processed products. The use of glass cloth filter aluminum melt, is a low cost, easy to use, with better results process. Glass cloth mesh is usually placed in the casting line of molten metal flow at the drop, and the flow casting mold and mold liquid metal hole, the implementation of a number of blocking filtration. For some important products, but also with other purification methods, such as corundum microporous filtration and continuous flow through the use of continuous refining to remove inclusions and gases in the liquid aluminum. Glass cloth filter aluminum melt in foreign countries for decades of history,
