Abstract
La invención se refiere a un procedimiento para enfriar esponja de hierro caliente en briquetas; con el cual se evita el enfriamiento irregular einsuficiente, los esfuerzos térmicos y por lo tanto el descamado, caracterizado porque en una primerae tapa de enfriamiento gradual se hace pasar a través dela esponja de hierro un medio gaseoso, preferiblemente aire de enfriamiento; en una segunda etapa, dicha esponja de hierro es rociada con un medio líquido deenfriamiento, preferiblemente agua,has ta la temperatura de enfriamiento final. La invención también proporciona una disposición para llevar a cabo dichoprocedimiento, caracterizada por la combinación de las siguientes características: una base permeable al gas para laespon ja de hierro; un mediode conducción de gas, y boquillas rociadoras.
