A leak detection device for blast furnace stave

Abstract

The invention relates to the technical field of blast furnace smelting, aims to solve the technical problems of complex process and high time cost during leakage detection of a blast furnace cooling wall and provides a blast furnace cooling wall leakage detection device which comprises a blast furnace body, a water supply pipe, a water return pipe, multiple water incoming elbow flowmeters, multiple master water incoming pipes, multiple water outgoing elbow flowmeters and multiple master water outgoing pipes. The water supply pipe is arranged around the blast furnace body at a furnace base of the same, each water incoming elbow flowmeter is connected with one end of a cooling water pipe through one master water incoming pipe, the water return pipe is arranged around the blast furnace body at a furnace top of the same, each water outgoing elbow flowmeter is connected with the other end of the cooling water pipe through one master water outgoing pipe, and the water incoming elbow flowmeters and the water outgoing elbow flowmeters are in one-to-one correspondence. Whether the cooling water pipe on the cooling wall is damaged or not is judged by utilizing flow change of the water incoming elbow flowmeters and the water outgoing elbow flowmeters, so that the leakage detection process is simple and convenient, and quick leakage detection of the blast furnace cooling wall is realized.

Description

technical field [0001] The invention relates to the technical field of blast furnace smelting, in particular to a leak detection device for a blast furnace stave. Background technique [0002] For the soft water closed circulation system of a large blast furnace, usually, low chromium cast iron staves or smooth cast copper staves are used in the hearth section, smooth nodular cast iron or smooth cast copper staves are used in the tuyeres, and smooth ductile iron or smooth cast copper staves are used in the tuyeres. Rolled copper staves are used for the waist section, and nodular cast iron staves are used for the middle and upper parts of the furnace body. However, no matter what kind of stave is used, once the blast furnace is used in the middle and late stages, the first damaged stave is still at the tuyere. The reason is that the tuyere is the coke gyration area, and coke combustion generates high temperature, and the stave will be damaged by high temperature thermal stres...
