Description

Technical Field

[0001] This utility model relates to the field of steelmaking process technology, and in particular to a tool for treating ladle nozzles. Background Technology

[0002] A ladle is a container used for transferring and pouring molten steel, playing a crucial role in the iron and steel smelting process. The ladle holds molten pig iron and molten steel, facilitating a series of processes including transfer, heat preservation, purification, and tapping. During the ladle-standing process after handling, slag easily falls from the ladle rim into the nozzle. Current tools for handling this slag, especially in ladles in the baking oven, present a significant problem. Once the slag pulverizes, it requires repeated ladle turning, impacting the ladle processing cycle. This simple tool is inconvenient to use and has functional limitations; it is easily damaged during use and ineffective at removing foreign matter from the nozzle, affecting the ladle's self-opening rate and severely impacting smelting production costs and operational efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a tool for treating ladle nozzles to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively ensures the rapid treatment of foreign objects in the nozzle after ladle slag turning and vertical tank operation, thus ensuring smooth production.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] This utility model provides a tool for treating the nozzle of a steel ladle, comprising: a working tube and a guide tube. The first end of the working tube is used to extend into the nozzle of the steel ladle and to contact and push out foreign objects inside the nozzle. The first end of the guide tube is vertically fixedly connected to and communicates with the second end of the working tube, so that the operator can hold the guide tube and guide the working tube into the nozzle. The second end of the guide tube is connected to and communicates with a nitrogen source so that nitrogen is blown out from the first end of the working tube. The nitrogen blown out from the first end of the working tube can sweep away the pulverized slag inside the nozzle.

[0006] Preferably, the working tube and the guide tube are integrally connected, and both the working tube and the guide tube are made of stainless steel pipe.

[0007] Preferably, it also includes multiple handles, which are fixedly connected to the guide steel pipe.

[0008] Preferably, the handle is provided with anti-slip texture.

[0009] Preferably, it also includes a nitrogen gas source, which is used to connect and communicate with the second end of the guide tube.

[0010] Preferably, it further includes a first quick connector and a second quick connector. The first quick connector is installed at the second end of the guide tube body, and the second quick connector is used to install the output end of the nitrogen gas source. The first quick connector is used to connect with the second quick connector.

[0011] Preferably, the first end of the working tube has a tapered structure.

[0012] The present invention achieves the following technical advantages over the prior art:

[0013] This utility model provides a tool for treating the nozzle of a steel ladle. When foreign objects are found in the nozzle after the ladle has been turned over and the ladle is uprighted, the operator holds a guide tube and aligns the first end of the working tube with the nozzle. The first end of the working tube is inserted into the nozzle, and upon contact with the foreign object, the operator pushes the guide tube to eject the object from the nozzle. If there are powdery slag or other foreign objects that are difficult to eject directly, the second end of the guide tube is connected to a nitrogen source. The nitrogen valve is opened to allow nitrogen to purge the powdery slag from the nozzle. The purging time is controlled at 10-20 seconds. During this process, the nitrogen accelerates the solidification of the liquid slag and achieves a good purging effect. The tool has a simple structure, is easy to use, and effectively ensures the rapid removal of foreign objects from the nozzle after the ladle has been turned over and the ladle is uprighted, guaranteeing smooth production.
