Rapid slag ladling device for molten steel in steel ladle

Abstract

The invention relates to a rapid slag ladling device for molten steel in a steel ladle. The rapid slag ladling device is provided with a slag ladling barrel body, the upper surface and the lower surface of the slag ladling barrel body are provided with openings, hoisting lug plates are arranged at the symmetrical positions of the side wall of the upper end of the slag ladling barrel body, a slag ladling tray is arranged in the slag ladling barrel body and divides the interior of the slag ladling barrel body into an upper part and a lower part, the height of the upper bottom surface of the slagladling tray is lower than the height of the upper end surface of the slag ladling barrel body, a plurality of slag overflow hole pipes are arranged in the slag ladling tray in a penetrating and inserted mode, upper ports of the slag overflow hole pipes are higher than the upper bottom surface of the slag ladling tray, lower ports of the slag overflow hole pipes penetrate through the lower bottomsurface of the slag ladling tray, and a plurality of small slag suction steel columns are downwards arranged on the lower bottom surface of the slag ladling tray. The rapid slag ladling device has the advantages that by designing a completely novel slag removal tool for a steel ladle, the slag impurity removal efficiency of the molten steel in the whole steel ladle is greatly improved, the wholedevice is very simple in structural design, and compared with traditional slag removal treatment, the rapid slag ladling device is safer and more efficient in operation and very obvious in actual useeffect.

Description

technical field [0001] The invention relates to the technical field of metal smelting tools and equipment, in particular to a ladle molten steel rapid ladle slag device. Background technique [0002] In the iron and steel smelting industry, the molten steel is usually transferred through the ladle. The molten steel usually cleans the scum on the upper layer of the molten steel in the ladle. At present, many smelting factories use cranes to lift the ladle and tilt it at a certain angle. After being placed on an incline, the scum and impurities with low density on the upper layer of molten steel will flow down to achieve the purpose of slag removal. Due to the large size and weight of the ladle and the high temperature of molten steel, this operation method has great potential safety hazards , the operation time is still relatively long, and the slag removal is not thorough enough, and even a certain amount of molten steel will be poured out when dumping, resulting in waste.

[0002] In the iron and steel smelting industry, the molten steel is usually transferred through the ladle. The molten steel usually cleans the scum on the upper layer of the molten steel in the ladle. At present, many smelting factories use cranes to lift the ladle and tilt it at a certain angle. After being placed on an incline, the scum and impurities with low density on the upper layer of molten steel will flow down to achieve the purpose of slag removal. Due to the large size and weight of the ladle and the high temperature of molten steel, this operation method has great potential safety hazards , the operation time is relatively long, and the slag removal is not thorough enough, and even a certain amount of molten steel will be poured out when dumping, resulting in waste. The above-mentioned drawbacks have not been well resolved in many iron and steel smelting factories
