Abstract

PURPOSE: To melt and remove sticked metal without damaging refractory material of converter wall by melting, by inserting gas lance able to go up and down freely from the converter opening and blowing combustion gas from the above lance.
CONSTITUTION: The water cooling type gas lance 4 is inserted into the converter 1 from the opening and is descended and then stuck metal 5 on the wall, is melted blowing the combustion gas, such as air, oxygen etc. and burning CO gas in the converter. On this occasion, heat current is able to control by the direction of the guide board 4a by attaching the board 4a at the lower end of the gas lance.
