Description

Technical Field

[0001] The invention relates to the technical field of casting slag dust removal hoods, and more particularly to a ground movable casting slag dust removal hood and a method thereof. Background Art

[0002] Casting slag is a mixture of molten steel and casting slag left after continuous casting or ingot casting. After each casting of molten steel in the ladle, there will always be a certain amount of liquid casting slag left in the ladle, and the amount of liquid casting slag is about 30kg / t steel. For these casting slag, the method of using a crane to pour the remaining casting slag in the ladle into the ground slag pot is often used, and then the slag pot containing casting slag is transported to the slag room for the next step of processing.

[0003] At present, as the environmental protection standards of the steel industry are becoming more and more stringent, steel mills attach great importance to flue gas treatment and standard emission. When the ladle is slag-dumping, a large amount of flue gas and dust will inevitably be generated. These pollutants will float in the factory and have a serious impact on the surrounding environment. Therefore, it is necessary to develop a new type of dust removal device and method to solve these problems. Summary of the invention
