Washing the tumor. The lower tumor is sometimes effective with a lot of fluorites. The method of cleaning the tumor: one is to adopt the method of full inversion and adding clean coke to strongly develop the edge airflow, so that the furnace tumor is melted under the action of the hightemperature airflow; the other is to spread the cleaning agent (such as soaking slag, fluorite, etc.)
