    • Coatings comprising metallurgical slag are applied to refractory substrates having molten metal-contacting surfaces to create a chemically active and viscous surface that dramatically increases the ability of the treated substrate to remove slag, dross and other inclusions from a base metal alloy as it passes through or contacts the substrate. The refractory substrates include molten metal filters used by foundries and metal casters such as reticulated ceramic foam, cellular/honeycomb, silica mesh, and others that rely on their physical or sieving ability to remove particulate impurities from the base alloy being cast. The chemically active surfaces significantly increase filtration efficiency through a treatment process tailored to the specific chemistry of the alloy being filtered, such as ferrous metals that include iron, steel and more. Other refractory substrates such as aluminum oxide, magnesium oxide, zirconium oxide, aluminum silicate, silicon carbide (as common with reticulated ceramic foam filters) and the like may also include the coatings.
    • 包括冶金炉渣的涂层被施加到具有熔融金属接触表面的耐火基材上,以产生化学活性和粘性的表面,其显着地增加了经过处理的基材当其通过时从贱金属合金去除渣,渣和其它夹杂物的能力,或者 接触基板。 耐火基材包括由铸造厂和金属脚轮如网状陶瓷泡沫,蜂窝状/蜂窝状,二氧化硅网等使用的熔融金属过滤器,其它依靠其物理或筛分能力从被铸造的基体合金中除去微粒杂质。 化学活性表面通过根据正在过滤的合金的具体化学特性的处理方法显着提高过滤效率,例如包括铁,钢等的黑色金属。 其它耐火基材如氧化铝,氧化镁,氧化锆,硅酸铝,碳化硅(与网状陶瓷泡沫过滤器一样)等也可以包括涂层。
