Problems solved by technology

Existing KR desulfurization molten iron slag, there are many subjective voluntary intervention operations, strong randomness: because the liquid level of molten iron is different, there is no fixed stop position when the molten iron tank is tilted, manual subjective judgment varies from person to person, and it is easy to generate a large amount of The iron slag stays in the molten iron tank, causing abnormal effects such as splashing on the converter smelting; at the same time, the existing slag removal method has the following problems: the iron slag removal effect is poor, the slag removal time is long, and it is difficult to meet the specified requirements; the slag accumulation effect Deterioration, low slag removal efficiency

Embodiment Construction

[0022] The present invention will be further described now in conjunction with accompanying drawing.

[0023] The present invention proposes a fast slag remover, such as figure 1 , 2 , 3, it comprises: slag removing connecting rod 6, O ring 3, slag removing head; The detachable O-rings 3 are connected together. This combination method has the characteristics of simple structure, convenient assembly, convenient manufacturing and processing, and can quickly replace the one-piece irregular steel part.

[0024] As one of the improvements to the above device, the slag removing head is an integrated convex structure, such as figure 1 with 2 As shown, it includes: connecting part 2 and slag head 4; connecting part 2 is provided with a square hole for connecting with slag removal connecting rod 6 through O-ring 3; slag head 4 is an arc protruding outward Shaped structure, and the four corners of the slag head 4 are set to be arc-shaped, forming a bottom edge with a large radian, a...

Abstract

The invention relates to a quick slag-off device. The quick slag-off device comprises a slag-off connecting rod (6), an O-shaped ring (3) and a slag-off head. A round hole is formed in the end portionof the slag-off connecting rod (6). A square hole is formed in the end portion of the slag-off head. The slag-off connecting rod and the slag-off head are connected together through the detachable O-shaped ring (3). The quick slag-off device has the characteristics of being simple in structure, convenient to assemble and convenient to make and machine, and with the quick slag-off device, an integrated irregular steel part can be quickly replaced.

Description

technical field [0001] The invention belongs to the technical field of iron and steel smelting equipment and slag removers, and in particular relates to a fast slag remover and a slag remover method. Background technique [0002] Many ladles used in steelmaking plants have varying degrees of bonding at the mouth of the ladle. After cleaning the slag accumulated at the mouth of the ladle, the slag that fell into the ladle must be turned over and poured out. If the slag in the ladle is not cleaned cleanly, there will be the following hazards: when the iron ladle is on the line, the molten iron poured into the ladle will cool down quickly; it will easily cause the ladle mouth to stick; If the iron slag in the furnace cannot be removed cleanly, it will easily affect the operation after entering the converter, such as splashing, etc., which will bring unnecessary losses; the ladle mouth needs to be cleaned repeatedly, which will reduce the service life of the iron ladle and make ...
