Title: Detection of wear of blast furnace stave
Inventor: YANAGISAWA KATSUHIKO
IPC: C21B7/24
Filed: 1985-05-17
Abstract: PURPOSE:To detect the damage of a stave directly and exactly by bringing an ultrasonic probe into contact with the outside surface of a part where the constituting member of the stave is packed so as to have no cavities and measuring the thickness of the stave. CONSTITUTION:A stave body 6 cast therein with a cooling pipe 4 is provided so as to inscribe a shell 2. The pipe 4 is sealed by a sealing metal 8. An aperture 12 is provided to the shell 2 on the outside in the part where the constituting member is packed to have no cavities and where the pipe 4 is not included with respect to the thickness direction of the body 6 from the furnace core toward the outside.
