Blast furnace iron hook with water-cooling devices

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of blast furnace smelting, in particular to a blast furnace iron hook provided with a water cooling device. Background technique [0002] Modern blast furnace ironmaking technology has greatly improved the production capacity of the blast furnace by increasing the air temperature (>1320°C) and the air pressure (>0.3MPa), but it also led to an increase in the temperature of molten iron slag and an increase in the amount of iron slag to be processed , the speed of tapping is accelerated and the number of tapping times is increased, so that the corrosion speed of the prefabricated part of the tapping channel is accelerated, the degree of erosion damage is increased, and the cost of lining and repair is greatly increased. Short, can not meet the demand. Contents of the invention [0003] In view of this, the present application provides a blast furnace iron hook equipped with a water cooling device, thr...
