Abstract

A method for extending the duration of the refractory lining of the furnaces to the basic coating oxygen for elevated temperatures to increase the total steel production of said furnaces, comprising the operation of sprinkling on the lining of a freshly coated furnace, while the furnace find at or near the operating temperature, a series of successive protective layers of compatible refractory material at intervals of sufficient duration to allow the first layer to dry, fix and fuse with the furnace lining and each subsequent layer layers are dried, fixed and melted with the preceding layer, until the thickness of the refractory lining has been sufficiently increased to withstand the deterioration that occurs during the batches of an increased production.
