Abstract
PROCEDIMIENTO PARA LIMPIAR LA SUPERFICIE DE UNA ESTRUCTURA REFRACTARIA. SE DESCRIBE UN PROCEDIMIENTO PARA LIMPIAR LA SUPERFICIE DE UNA ESTRUCTURA REFRACTARIA A TEMPERATURA ELEVADA, EN PARTICULAR COMO PREPARACION PARA SOLDADURA CERAMICA. EL PROCEDIMIENTO COMPRENDE PROYECTAR CONTRA DICHA SUPERFICIE UNA CORRIENTE DE POLVO QUE ARRASTRA PARTICULAS DE COMBUSTIBLE EN UN GAS PORTADOR QUE CONTIENE OXIGENO, CON LO QUE LAS PARTICULAS DE COMBUSTIBLE Y EL OXIGENO EN EL GAS PORTADOR REACCIONAN EN UNA ZONA DE REACCION SOBRE DICHA SUPERFICIE, Y PROYECTAR SIMULTANEAMENTE SOBRE DICHA SUPERFICIE UNA CORRIENTE DE EROSION QUE COMPRENDE OXIGENO, PREFERIBLEMENTE A UNA VELOCIDAD DE DESCARGA MAYOR QUE LA DE LA CORRIENTE DE POLVO, PARA EROSIONAR DICHA SUPERFICIE EN LAS PROXIMIDADES DE LA ZONA DE REACCION.
