Abstract

The invention provides a rapid pressure testing device and method for a blast furnace cooling wall, and belongs to the technical field of blast furnace cooling walls. The device comprises a water source, a pressure stabilizing unit, a pressure testing pump used for connecting the water source and the pressure stabilizing unit, and a testing unit used for testing the cooling wall; the pressure stabilizing unit is used for distributing water of a water source to each testing unit; the test unit comprises more than two cooling walls which are connected in series; in the testing unit, the water inlet of the cooling wall at the front end is connected with the pressure stabilizing unit, and the water outlet of the previous cooling wall is connected with the water inlet of the next cooling wall through a testing connecting pipe; a pressure gauge and an exhaust valve are arranged at the water outlet of the cooling wall at the tail end; the method has the technical effects of reducing the pressure test cost and improving the pressure test efficiency.

Description

technical field [0001] The invention relates to the technical field of blast furnace cooling stave, in particular to a device and method for rapid pressure testing of blast furnace cooling stave. Background technique [0002] In order to maintain the normal operation and safe production of the blast furnace in the ironmaking system, it is necessary to equip the blast furnace with a blast furnace stave, and the blast furnace stave must withstand the wear of the charge, the erosion of the slag and the erosion of the gas flow during production. In order to ensure the blast furnace stave The normal use of the blast furnace requires a pressure test before the cooling stave is installed; but the pressure test of the blast furnace cooling stave, due to the large number of blast furnace cooling walls, a blast furnace corresponds to more than 500 blast furnace cooling walls, and each cooling wall is inside There are 1 to 4 cooling water pipes; the pressure test workload is huge, the ...
