Full-suspension four-point engagement type super-large converter mounting method

Abstract

The invention relates to the mounting field of large metallurgical equipment, in particular to a full-suspension four-point engagement type super-large converter mounting method which is characterizedby comprising the following steps: mounting a converter bearing support base cushion plate; mounting a strokehold operation platform structure framework main beam; mounting a bearing support base; assembling a support ring lug shaft bearing and a bearing base; hoisting a support ring; hoisting a furnace shell; arranging a tilting device transmission mechanism in the lug shaft; integrally slidingthe converter; mounting the furnace body; assembling a tangential ley; and grinding by a cutter, and confirming that a gap between an end cover and the key is zero. The original large converter equipment jacking mounting method is optimized and improved, so that safety and quality hidden danger in upper and lower furnace shell turnover processes in the conventional super-large converter jacking mounting method are reduced, and therefore, converter mounting is more scientific, is safer and is more economical.

Description

technical field [0001] The invention relates to the field of installation of large-scale metallurgical equipment, in particular to an installation method of a full-suspension four-point meshing super-large converter. Background technique [0002] During the process, the feeding span metallurgical bridge crane hoisted the upper furnace shell separately into the support ring, installed the anti-tipping device, and then used the feeding span metallurgical bridge crane to turn over and fix the support ring and the upper furnace shell by 180° as a whole. Finally, hoist the lower furnace shell, align and align the upper and lower furnace shells on the support ring, and control the deviation of the welding seam, and finally use the sliding beam and synchronous hydraulic jack to slide the support ring, furnace shell and tilting device as a whole The entire sliding process is relatively simple to operate, but there are also disadvantages: 1.

[0002] During the process, the feeding span metallurgical bridge crane hoisted the upper furnace shell separately into the support ring, installed the anti-tipping device, and then used the feeding span metallurgical bridge crane to turn over and fix the support ring and the upper furnace shell by 180° as a whole. Finally, hoist the lower furnace shell, align and align the upper and lower furnace shells on the support ring, and control the deviation of the welding seam, and finally use the sliding beam and synchronous hydraulic jack to slide the support ring, furnace shell and tilting device as a whole The entire sliding process is relatively simple to operate, but there are also disadvantages: 1. The entire furnace shell turning process is relatively complicated, and the metallurgical bridge crane is frequently used for feeding the span; 2. The upper and lower furnace shells are assembled at high altitude. It is necessary to set up a temporary safety measures platform to ensure the safe welding of the furnace shell; 3. In terms of quality, the upper and lower furnace shells are assembled at high altitude, and it is difficult to control the deviation of the welding seam. Gouging and root cleaning and ultrasonic pen 100% inspection, therefore, it is difficult to control the quality of high-altitude furnace shell assembly and welding
