STAVE COOLER
Document Type and Number:
WIPO Patent Application WO/2000/050831
Kind Code:
A1
Abstract:
A stave cooler used for cooling a furnace wall of a metallurgy furnace such as a blast furnace, wherein cooling tubes which cool a base metal is cast into the base metal on the outside of the furnace, one or several heat resisting steel sheets having a plurality of openings are laminated on the base metal on the inside of the furnace, and casting is made at a specified thickness, a laminated body thus obtained being allowed to be formed in a rectangular body, and a plurality of rectangular bodies being allowed to be cast in the base metal on the inside of the furnace, whereby a wear rate of the surface on the inside of the furnace can be reduced, and the falling-off of the heat resisting steel due to thermal expansion of a stave cooler main body or local wear can be prevented.
