Construction method for replacing steelmaking converter flue

Abstract

The invention discloses a construction method, in particular relates to a construction method for replacing a steelmaking converter flue and belongs to the technical field of repair and maintenance of metallurgical production equipment. The construction method for replacing the steelmaking converter flue is simple to operate, and the construction period of the construction method is greatly shortened, while the replacement cost is obviously reduced. According to the construction method, hoisting apparatuses are mounted above a cluster cover in the vertical direction and on the outer side of the cluster cover in the horizontal direction, respectively; and next, the cluster cover and a fixed smoke cover section can be removed and mounted by use of the hoisting apparatuses in combination with a hoisting machine arranged on the outer side of the steelmaking converter.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for replacing a steelmaking converter flue, and belongs to the technical field of metallurgical production equipment repair and maintenance. Background technique [0002] Steelmaking converter vaporization flue equipment in steelmaking plants must collect high-temperature flue gas to the maximum extent during work, and withstand the highest furnace gas temperature and severe and frequent temperature changes. Therefore, the vaporization flue equipment used in such a harsh environment is easy to age, and inevitably burns out and corrodes. If water leakage occurs due to burning, rust, etc., it will leave hidden dangers for safe production and cannot meet normal production needs. Therefore, immediate replacement of the vaporization flue equipment of the steelmaking converter becomes equipment maintenance Maintenance essential work. The vaporization flue installed on th...

Problems solved by technology

Therefore, the vaporization flue equipment used in such a harsh environment is easy to age, and it is inevitable that there will be burnout and corrosion

If water leakage occurs due to burning, rust, etc., it will leave hidden dangers for safe production and cannot meet normal production needs. Therefore, immediate replacement of the vaporization flue equipment of the steelmaking converter becomes equipment maintenance maintenance essential work

The vaporization flue installed on the top of the steelmaking converter is usually located in the middle and upper part of the workshop with a small space, which is inconvenient for repair, maintenance or overall replacement.

In the prior art, especially in the overall replacement, it is not only necessary to dismantle the plant equipment around the vaporization flue, but also to use large mobile hoisting equipment, such as large cranes, etc., which is not only expensive, but also takes a long time
