Abstract: A filter for molten metal is an open-pored porous material comprising particles of refractory material embedded in and bonded together by a carbon matrix bonding material. The filter can be made by forming a porous article from refractory particles, e.g. refractory oxide, carbide or graphite, and a carbon-rich binder, e.g. tar, pitch or an organic (preferably aromatic) polymer that degrades to form carbon on pyrolysis, and then firing the porous article to generate the carbon matrix in which the refractory particles are embedded. The porous article is preferably made by coating a reticulated polyurethane foam with binder and refractory particles, and firing at preferably no higher than 800° C.
Abstract translation: 用于熔融金属的过滤器是开孔多孔材料,其包含嵌入并通过碳基质粘合材料粘合在一起的耐火材料颗粒。 过滤器可以通过从难熔颗粒形成多孔制品来制造,例如, 难熔氧化物,碳化物或石墨,以及富含碳的粘合剂,例如, 焦油,沥青或有机(优选芳族)聚合物,其在热分解时降解形成碳,然后焙烧多孔制品以产生其中嵌入耐火颗粒的碳基质。 多孔制品优选通过用粘合剂和耐火颗粒涂布网状聚氨酯泡沫,并优选不高于800℃进行烧制来制备。
