Pouring flue gas dust removal process for continuous casting big ladles

Abstract

The invention relates to a pouring flue gas dust removal process for continuous casting big ladles. The process comprises the following steps: putting a full pack of steel ladles into a revolving table; rotating the revolving table to a pouring position; moving a movable cover on the upper parts of pouring steel ladles; performing sealing and closure between a fixed cover and the movable cover; beginning to pour the full pack of steel ladles; sucking away flue gas produced in a pouring process by a fan arranged above an operation platform through an air suction hole formed in the fixed cover,and simultaneously, preparing the full pack of steel ladles on a hoisting position; rotating the revolving table to 180 degrees when the pouring is carried out; enabling empty steel ladles to enter into the hoisting position and the full pack of steel lades to enter into the pouring position, and moving the movable cover to the upper part of the pouring position to make room for hoisting; and then repeatedly carrying out the steps. According to the pouring flue gas dust removal process for the continuous casting big ladle disclosed by the invention, through a flue gas collection device with the revolving table for the continuous casting big ladles, dispersion of flue gas is hindered in a process of pouring the big ladles, a flue gas collection ratio is increased, and a workshop environment is improved; and compared with a conventional roofing cover, the pouring flue gas dust removal process disclosed by the invention has the advantages that one-time investment and operation expenses are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a continuous casting ladle pouring flue gas dedusting process. Background technique [0002] The ladle turret, also known as the ladle turret, is the most commonly used equipment for carrying and supporting the ladle for pouring in modern continuous casting. It is usually installed between the molten steel receiving span and the pouring span column. Due to the particularity of the operation and equipment of the bale turret, the current mainstream form of the capture hood is the roof cover. Although the roof cover has no effect on the production operation, the temperature of the flue gas is low when the bale is poured, and the thermal lift is small. The pouring flue gas is mainly the flue gas from the nozzle to the tundish, and the flue gas is easily dispersed by the ladle. At present, in order to improve the operating environment of workers on the platform, such a...

Due to the particularity of the operation and equipment of the bale turret, the current mainstream form of the capture hood is the roof cover. Although the roof cover has no effect on the production operation, the temperature of the flue gas is low when the bale is poured, and the thermal lift is small. The pouring flue gas is mainly the flue gas from the nozzle to the tundish, and the flue gas is easily dispersed by the ladle

At present, in order to improve the operating environment of workers on the platform, such as opening, blocking water, temperature measurement, and feeding, industrial axial fans are usually used to blow away hot air, so that the smoke in the entire pouring area is in a dispersed state, and it is difficult for the smoke to rise into the roof cover , resulting in a very low smoke capture rate

Furthermore, when the dust particles are large, they are easy to settle in the factory building, destroying the workshop environment and shortening the service life of the workshop equipment.
