Abstract

Procedimiento mejorado para reparar el revestimiento refractario de hornos industriales y recipientes que funcionan en caliente, mediante aplicación de una masa refractaria con adición de agua, mediante una máquina inyectora o una máquina centrifugadora rotatoria, siendo alimentada en estado seco la masa refractaria a la máquina inyectora o centrifugadora y siendo mezclada con agua en la máquina mediante una boquilla mezcladora, caracterizado porque en el agua a añadir a la masa se introduce un agente humectante, que reprime el desprendimiento de polvo y produce, dentro del corto tiempo que transcurre desde el paso de la masa a través de la boquilla mezcladora hasta la incidencia sobre la mampostería del horno, un humedecimiento lo más completo posible de la masa con agua.
