Abstract
PURPOSE: To make repairing during operation possible by beforehand inserting a refractory cylindrical body into a blast furnace wall at the blowing out, removing the cylindrical body at the operating and pouring monolithic refractories through the through-hole thereof.
CONSTITUTION: At the blowing out of a blast furnace, the part of a shell 3 where red hot occurs frequently is incised and a furnace wall 2 is pierced with a hole. A refractory cylindrical body filled with refractories is inserted into this pierced through-hole 4. A flange 6 connected with a sluice valve 7 and an extruder is welded to the incised part of the shell 3. Next, when the blast furnace is operated again and a need for repair arises on elevation of the temp. of the shell, the valve 7 is opened, and the cylindrical body is pushed into the furnace to open hole. Thence, a monolithic refractory injection nozzle 9 is mounted to the valve 7, and monolithic refractories 10 are injected. The refractories 10 injected into the furnace in this way are dried and solidified by the heat in the blast furnace.
