Abstract

"ARTIGO REFRATáRIO" é descrito um artigo refratário contendo carbono possuindo um revestimento protetor. O revestimento protetor reduz a oxidação do artigo durante as operações de pré-aquecimento e de lingotamento. Um auxiliar de umectação de lata temperatura compreendendo um óxido de metal, o metal sendo selecionado do grupo consistindo de arsênio, antimónio, busmuto, chumbo, vanádio e estanho, melhora a umectação do revestimento protetor sobre o artigo, e deste modo reduz as imperfeições no revestimento protetor fundido. O revestimento protege o artigo contra a oxidação e a descarbonetação, que podem resultar do uso do artigo em temperaturas elevadas em um atmosfera oxidante. O auxiliar de umectação é um óxido de metal, tal como óxido de bismuto, que reduz a tensão superficial do revestimento protetor em alta temperatura e promove o espalhamento do revestimento protetor sobre a superfície do artigo."REFRACTORY ARTICLE" is a refractory article containing carbon having a protective coating. The protective coating reduces the oxidation of the article during preheating and casting operations. A high temperature wetting aid comprising a metal oxide, the metal being selected from the group consisting of arsenic, antimony, busmute, lead, vanadium and tin, improves the wetting of the protective coating on the article, and thus reduces imperfections in the fused protective coating. The coating protects the article against oxidation and decarburization, which can result from using the article at elevated temperatures in an oxidizing atmosphere. The wetting aid is a metal oxide, such as bismuth oxide, which reduces the surface tension of the protective coating at high temperature and promotes the spreading of the protective coating on the article surface.
