Abstract

MÉTODO PARA CONTROLAR A FORMAÇçO DE ASPEREZA DE SUPERFICIE TIPO PELE DE JACARÉ NA FUNDIÇçO CONTINUA DE TIRA FUNDIDA FINA DE AÇO CARBONO COMUM. Expõe-se um método para controlar a formação de aspereza de superfície tipo pele de jacaré em tira fundida fina de aço carbono comum, formando uma poça de fundição de metal fundido de aço carbono comum de menos que 0,065% de carbono suportada em superfícies de fundição acima de uma beliscadura, montar uma escova rotativa para contactar as superfícies de fundição antes do contacto com o metal fundido, e controlar a energia exercida pelas escovas rotativas contra as superfícies de fundição dos cilindros de fundição para limpar e expor uma maioria das projeções das superfícies de fundição dos cilindros de fundição para proporcionar contacto de umedecimento com o metal fundido da poça de fundição. A etapa de limpeza pode ser realizada pelo controle da energia da escova rotativa contra os cilindros de fundição com base na diferença entre o fluxo térmico medido e o fluxo térmico inicialmente me- dido quando as superfícies de fundição estão limpas, e automatização do método.
