Abstract
"INIBIDOR DE VóRTICE E MéTODO PARA APERFEIçOAR PROCESSOS DE DERRAMAMENTO DE METAL". Método e aparelho para processamento metalúrgico intensificado de metal fundido incluem uma câmara de colher (23) encerrável, para reduzir o escape de calor durante o transporte da colher de um vaso de fabricação, tal como um forno (13), para uma estação de processamento intermediário (15) ou de refinamento, ou durante o processamento ou o transporte para um vaso receptor, tal como uma panela (17). O método compreende introduzir um corpo refratário na câmara da colher (23), o corpo tendo uma densidade ajustada com uma razão reduzida entre o lastro de aço e o material refratário que é menor do que o necessário para uma densidade requerida para sustentar de modo flutuante o corpo no metal fundido. De preferência, a razão proporciona uma densidade maior do que a densidade requerida para sustentar de modo flutuante o corpo inteiramente na camada de escória. O método inclui encerrar a colher (22), por exemplo, com uma tampa (90) e manter o corpo refratário na colher até o término substancial da descarga do, metal fundido do vaso. De preferência, o método também inclui refino intermediário, tal como pela introdução de uma composição de balanceamento na colher antes do encerramento. A razão de lastro de aço e material refratário usada para atingir a densidade preferida também pode ser ajustada em conjunto com outras mudanças resistentes a temperaturas ou resistentes a corrosão no corpo refratário. Por exemplo, alumina de alta temperatura pode ser usada como um material refratário em um grau maior do que em corpos anteriormente conhecidos, um cimento de alta temperatura pode ser usado para unir o material refratário e os componentes de lastro, e um agente não umectante feito de material carbonáceo ou silicoso pode reduzir a deterioração do corpo durante o período prolongado do contato do aço e da escória na colher.
