Abstract
The disclosed process uses a vertical remote controlled refractory gunning apparatus to repair damages to the stack, bosh, or hearth of a blast furnace. In the disclosed method, a reusable opening is created in the side of the blast furnace and a gantry, for example, is inserted through the reusable opening. The vertical remote-controlled refractory gunning apparatus is then introduced into the blast furnace via the gantry. In those cases wherein the blast furnace is loaded through a chute, the chute is moved to one side, the gantry is introduced at an angle and the vertical remote controlled refractory gunning apparatus is introduced through the opening.
