Online replacement construction method for sintering nine-roller distributing machine

Abstract

The invention provides a construction method for online replacement of a sintered nine-roll distributing machine. The on-line replacement construction method of the sintered nine-roll distribution machine of the present invention is mainly to change the traditional construction method from transporting the old nine-roll distribution machine out of the installation position from the front of the sintering machine to transporting the old nine-roll distribution machine out of the installation position from the side of the sintering machine , and the process of reversing the old and new nine-roller distributing machine from the hoisting platform to the installation position platform uses the special tooling for distributing the distributing machine to replace the driving, etc., reducing the use of driving during shutdown, and will not affect other cross-projects. The construction time is short and the maintenance efficiency is improved. At the same time The construction safety factor is higher.

Description

technical field [0001] The invention relates to a construction method of a sintered nine-roll distribution machine, in particular to an online replacement construction method of a sintered nine-roll distribution machine. Background technique [0002] The nine-roll distribution machine is an important part of the feeding device of the sintering machine. The nine-roll distribution machine is located between the round roller and the ventilation rod. Its main function is to make the distribution uniform and produce physical segregation, so that the sintering effect of the mixture is better. The overall size of the nine-roller distributing machine is 7,780 meters long, 1,550 meters wide, and 1,405 meters high; the size of the roller body is 150 meters long, 6,000 meters wide, and 20 meters high; the weight of the nine-roller distributing machine is 11.12 tons. The nine-roll distribution machine is mainly composed of a frequency conversion motor, a reducer, a nine-roll device, a b...

AI Technical Summary

Problems solved by technology

[0004] The existing on-line replacement of the nine-roll distributing machine is carried out from the old nine-roll distributing machine from the front of the sintering machine to the installation position. Due to the narrow space and location, the construction is difficult, resulting in a long construction time and low construction efficiency. At the same time , construction safety is not high

In addition, the old and new nine-roller distributing machine processes are mainly completed by driving, and there are serious conflicts in the use of driving during the fixed-year repair period, which affects the construction progress of other cross-projects
