Abstract

The invention discloses a blast furnace top flange jackscrew aligning method which is characterized in that a regulating nut of a jackscrew is welded on the end of a steel plate, the four steel plates welded with the adjusting nuts are welded on a furnace casing right below the cross center of a furnace top flange, the jackscrew is screwed in the adjusting nut, and the levelness of the flange is adjusted by adjusting the jackscrew according to practically measured height difference of a measuring tower ruler leveling instrument. The blast furnace top jackscrew aligning method comprises the following steps of: 1. welding the adjusting nut; 2. hanging the furnace top flange; 3. welding the steel plates; 4. and adjusting the levelness of the flange. The blast furnace top jackscrew aligning method has the advantages of being simple to operate, convenient and fast and high in aligning efficiency, greatly shortening the aligning time of the blast furnace top flange, creating conditions for installing the blast furnace equipment, shortening the construction period, and lowering the cost.

Description

technical field [0001] The invention relates to the technical field of equipment installation, in particular to a method for aligning a top flange top wire of a blast furnace, which is used for installation and construction of blast furnace top equipment. Background technique [0002] In the existing metallurgical construction, the method of aligning the flange installation of the blast furnace roof is to weld the baffle plate on the furnace shell and the flange, and then adjust it with a jack. construction period. Contents of the invention [0003] The object of the present invention is to provide a method for aligning top wires of blast furnace roof flanges to shorten the alignment time of blast furnace roof flanges and reduce costs in view of the above-mentioned shortcomings in the prior art. [0004] The blast furnace top flange top wire alignment method of the present invention is realized in this way: the blast furnace top flange top wire alignment method is charact...
