Embodiment Construction

[0023] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0024] See Figure 1-Figure 2 , is a structural schematic diagram of the device of the present invention. A slag scraping and breaking device for a ladle of the present invention includes a main body and a hanging piece. At least two scrapers 8 are provided on each of the four sides of the table 6, and an operation hole 9 is provided above each side; 5 links to each other with the suspender 4 above main body square platform 6.

[0025] Two scrapers 8 are respectively arranged on the four sides of the quadrangular pedestal 6, and the height of the quadrangular pedestal 6 is h, and the upper edge of the scraper blade 8 is respectively positioned at 2 / 8h of the first side of the quadrangular pedestal 6, the second At 3 / 8h of the side, 4 / 8h of the third side, and 5 / 8h of the fourth side, the two scrapers 8 on the same surface are arranged at the sam...

Abstract

The invention relates to a slag scraping and breaking device for a steel ladle. The slag scraping and breaking device comprises a body and a hanger. The upper portion of the body is a quadrangular frustum pyramid; the lower portion of the body is an inverted cone frustum; at least two scrapers are arranged on each of the four side faces of the quadrangular frustum pyramid; and operating holes are formed in the upper portions of all the side faces. The hanger is composed of a connector, a sling and a hanging ring, wherein the connector is connected with a hanging rod on the quadrangular frustum pyramid of the body through a pin shaft. An application method of the slag scraping and breaking device comprises the steps that (1) when pot edge steel slag is processed, the upper edges of the scrapers are aligned at the pot edge steel slag; (2) when pot inner wall steel slag is processed, the outer edges of the scrapers are aligned at the pot inner wall steel slag; and (3) when pot bottom layer bonding slag is processed, a slag crust is broken under the gravity action. Compared with the prior art, the slag scraping and breaking device has the beneficial effects that (1) the problem of slag scraping and breaking of an opening, the inside and the bottom of a steel ladle pot can be solved, and the device is not limited by sites; (2) the structure is simple, manufacturing is convenient, and operation is flexible and convenient; and (3) the slag cleaning effect is good, the efficiency is high, smooth production is guaranteed, and the labor intensity of workers is lowered.

Description

technical field [0001] The invention relates to a ladle cleaning device for steelmaking, in particular to a slag scraping and slag breaking device for a steel ladle and a use method thereof. Background technique [0002] Ladles are used in steelmaking plants and foundries to receive molten steel and perform pouring operations before open hearth furnaces, electric furnaces or converters. When ladle is used for smelting, due to the violent stirring and turning of molten steel and surface slag, part of the slag will adhere to the mouth of the ladle and form a thicker and wider slag accumulation layer at the edge, seriously affecting the normal production. In addition, after the pouring of molten steel in the ladle is completed, there will be residual slag remaining on the inner wall of the ladle and the bottom of the tank. The steel slag at the bottom of the tank will form a layer of hard slag shell after cooling, which can only be cleaned after breaking the slag. At present, ...
