PURPOSE: A cooling pipe fixing structure for a blast furnace stave is provided to suppress cracking by improving connection and welding structure with a cooling plate of a cooling pie of a stave cooler. CONSTITUTION: A cooling pipe fixing structure for a blast furnace stave comprises a cooling plate(11), and a plurality of cooling pipes(20). The end of the cooling pipe is extended to the outside. The end is coupled with the cooling plate. The cross-section of the end is horizontal to a recess surface(13) of the cooling plate. The lower part(15) of a recess surface of the cooling plate has the same curvature as an extended portion(22) of the cooling pipe. An incline(14) is formed on the inner circumference of the recess surface of the cooling plate. |
