Embodiment Construction

[0019] like Figure 1 to Figure 7 Shown is a construction method for replacing the flue of a steelmaking converter provided by the present invention, which is simple in operation, greatly shortens the construction period, and significantly reduces the replacement cost. Described construction method comprises the following steps,

[0020] First, the group hood 1 of the vaporization flue that needs to be replaced, and the installation center and the elevation of the fixed hood section 2 connected to the group hood 1 are respectively mapped to the fixed foundation outside the steelmaking converter 3; Lifting equipment 4 is respectively installed on the vertical top and the horizontal outside of the group hood 1; then the group hood 1 and the fixed fume hood section 2 are successively cut and separated from the vaporization flue; then through the The hoisting equipment 4 is hoisted and dismantled with the cooperation of the hoisting machinery 5 arranged outside the steelmaking co...

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...
