Blast furnace iron hook with water-cooling devices

The invention discloses a blast furnace iron hook with water-cooling devices. The iron hook comprises a groove, a protective groove and the water-cooling devices, wherein the groove is formed in the top of the protective groove, the side wall of the protective groove is vertically arranged, the bottom of the protective groove is horizontally arranged, and the water-cooling devices are arranged at two sides of the protective groove; each water-cooling device comprises a shell, a water pipe, a metal ceramic casting body, a first metal backboard and a second metal backboard; the first metal backboards and the second metal backboards are vertically arranged; a cavity is formed by one side of each first metal backboard and the corresponding shell, and each metal ceramic casting body is used for filling a space between the other side of the corresponding first metal backboard and the corresponding shell; the water pipes are arranged between the first metal backboards and the second metal backboards, and are paved on the second metal backboards, and the water pipes and the second metal backboards are embedded in the metal ceramic casting bodies; two ends of each water pipe are respectively a water inlet section and a water outlet section, and the inlet sections and the water outlet sections penetrate through the first metal backboards and are located in the cavities. The cooling of the iron hook can be realized by the water-cooling devices, the cooling effect is good, and the service life of the iron hook is prolonged.
