Abstract

"MéTODO PARA REDUZIR DEFEITOS DE PRODUTO NA PRODUçãO DE PRODUTOS CERâMICOS DURANTE O PROCESSO DE QUEIMA E PARA AUMENTAR A TAXA DE PRODUçãO DOS CITADOS PRODUTOS CERâMICOS". Esta invenção refere-se a um processo para redução de defeitos na produção de produtos cerâmicos durante o processo de queima de produtos cerâmicos. Uma atmosfera oxidante é proporcionada em um forno de calcinação com roletes na vizinhança dos elementos de aquecimento para manter uma atmosfera oxidante aquecida. O produto cerâmico é passado através da vizinhança da atmosfera oxidante para queima. Os produtos cerâmicos são queimados na presença de atmosfera oxidante."METHOD TO REDUCE PRODUCT DEFECTS IN THE PRODUCTION OF CERAMIC PRODUCTS DURING THE BURNING PROCESS AND TO INCREASE THE PRODUCTION RATE OF THE CERTAIN CERAMIC PRODUCTS". This invention relates to a process for reducing defects in the production of ceramic products during the process of burning ceramic products. An oxidizing atmosphere is provided in a rolling calcining oven in the vicinity of the heating elements to maintain a heated oxidizing atmosphere. The ceramic product is passed through the vicinity of the oxidizing atmosphere for burning. Ceramic products are burned in the presence of an oxidizing atmosphere.
