Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for steel plants, in particular to an online ladle rapid slag cleaning device. Background Art

[0002] In the production of converter smelting process, ladle is an important transportation, storage and smelting tool. In actual production, the temperature of slag continues to drop during the lifting and casting process of the ladle, causing the slag to adhere to the ladle wall. As the number of times the ladle is used increases, the volume of slag accumulated on the ladle wall becomes larger and larger, resulting in the residual slag being unable to be turned over and the slag accumulation increasing rapidly. The slag accumulation in the ladle will affect the temperature of the molten steel and increase the difficulty of smelting. At present, the slag cleaning method adopted by most steel mills is: put the ladle on the ladle car and let the overhead crane use the anchor hook to go down into the ladle and hook up the slag. This method is difficult to operate, takes a long time, the slag cannot be cleaned up, the slag is easy to fall into the ladle water outlet, and it is easy to cause the ladle to tilt and the ladle ear shaft to tip over. There are a series of problems. Utility Model Content

[0008] The base comprises a horizontally arranged pedestal and a supporting surface vertically arranged at one end point of the pedestal; the supporting surface is a circular disc, and the knife seat is arranged on the circumference of the supporting surface.

[0009] A further improvement of the technical solution of the utility model is that the razor is 50-100 cm long, 20 cm high and 20 cm wide.

[0010] A further improvement of the technical solution of the utility model is that the gap distance is 5 to 20 cm.

[0011] A further improvement of the technical solution of the utility model is that an observation port is arranged on the support surface.

[0012] A further improvement of the technical solution of the utility model is that a support frame is arranged on the back of the knife holder, and the support frame is mounted on the base at an angle of 45 degrees to the base.

[0013] A further improvement of the technical solution of the utility model is that the razors are arranged in four groups, the gaps of each group of razors are aligned with the back of the knife holder of each group of razors, and a support frame is arranged, with a total of four support frames, and the four groups of razors are aligned with the wall of the ladle.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the utility model is:

[0015] Compared with the existing slag cleaning technology, the utility model provides a fast online slag cleaner for a ladle, which shaves off the accumulated slag in the ladle by a razor through the movement of the hot repair ladle car and then lifts it up by a crane to turn over the slag. It has the advantages of simple structure, low cost, high efficiency, safety, simple operation, and clean slag cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
