Abstract

The invention provides a pressure testing device and method of a cooling wall of a blast furnace. The device comprises a pressing plate, hoisting mechanisms, supporting columns and connecting rod structures, wherein the hoisting mechanisms, the supporting columns and the connecting rod structures are arranged at two ends of the pressing plate; the supporting columns are arranged between the end part of the pressing plate and the hoisting mechanisms; the connecting rod structures penetrate through the supporting columns; the driving ends, hinged with the hoisting mechanisms, of the supporting columns are connected to the first ends of the connecting rod structures and are used for driving the first ends of the connecting rod structures to up and down reciprocate; and the second ends of the connecting rod structures are pressed to the pressing plate and are rotatably connected to the pressing plate, and the second ends of the connecting rod structures are used for applying downward pressure to the pressing plate while the first ends of the connecting rod structures upwards move so as to compress a plurality of water cooling pipes through the pressing plate. According to the device, the top parts of the plurality of water cooling pipes are pressed through the pressing plate, and a hoisting mechanism set and a connecting rod structure set are arranged at each of two sides of the pressing plate; the hoisting mechanisms and the connecting rod structures are matched to apply pressure to the pressing plate from two ends, and thus the plurality of water cooling pipes can be synchronously compressed so as to perform pressure test on a workpiece, and as a result, the pressure test efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment installation, in particular to a blast furnace stave pressure test device and method. Background technique [0002] The furnace walls of modern ironmaking blast furnaces are all equipped with water-cooled staves. The main body of the staves is divided into iron staves and copper staves. The interior is composed of curved water pipes. The effect of cooling the blast furnace hearth. Therefore, the most important detection index of the blast furnace stave is that the internal cooling water pipe does not leak or bubble under the design pressure. [0003] A blast furnace stave generally consists of more than 300 pieces, and a stave cold water pipe is in the form of 4 in and 4 out, so the pressure test workload is very large. The current stave water pressure test device mainly adopts the following two methods: 1. Use rubber rings to block the steel pipe ports, and use the rubber rings ...
