Cover adding and uncovering method and device for ladle in processing station

Abstract

The invention relates to a ladle and provides a cover adding and uncovering method for a ladle in a processing station. The cover adding and uncovering method comprises the steps that before the ladle is transported to the processing station, a ladle cover is taken down through a cover uncovering mechanism in a cover uncovering station and then placed on a storage rack of a ladle car; and after processing is completed in the processing station, the ladle cover is buckled on the ladle from the storage rack through a cover adding mechanism in a cover adding station. The invention further provides a cover adding and uncovering device. The cover adding and uncovering device comprises the ladle car and further comprises the cover uncovering mechanism and the cover adding mechanism. A moving path of the ladle car is arranged between the cover uncovering mechanism and the cover adding mechanism. The processing station of the ladle is located on the moving path. The ladle car is provided with the storage rack for containing the ladle cover. According to the cover adding and uncovering method and device for the ladle in the processing station, the cover uncovering station and the cover adding station are separately arranged, and under the matching action of the storage rack of the ladle car, the clearance requirement in the processing station is very low, that is, the cover adding and uncovering method can adapt to the low clearance environment in the processing station; and in addition, the cover adding and uncovering method can further meet the occasions where ladles need to penetrate through processing stations along with covers and adapts to any old factory ladle cover adding project reconstruction.

Description

technical field [0001] The invention relates to a steel ladle, in particular to a method and device for uncovering and uncovering a steel ladle at a processing position. Background technique [0002] The ladle is used as a steel container between the steelmaking process and the continuous casting process. In order to ensure the normal production and product quality of the continuous casting billet, the pouring temperature of molten steel must be strictly controlled within the pourable range. There are two main ways for the heat loss of molten steel: one is that the refractory itself absorbs and stores the heat of molten steel; the other is the heat conduction and heat radiation between the molten steel and the air directly. Taking a 150t steel ladle as an example, after the empty ladle starts, the radiation heat loss from the lining to the air in the first 20 minutes will cause the temperature loss of the next furnace molten steel to reach 15°C, and 40% of this heat loss occ...
