Ladle hooking device for bonded slag of steel ladle and machining method of ladle hooking device

Abstract

The invention discloses a ladle hooking device for bonded slag of a steel ladle. The ladle hooking device comprises a pull rod and a ladle hooking device body. A long threading hole is formed in the middle of the upper portion of the pull rod. A ladder table is arranged at the bottom of the pull rod. The whole ladle hooking device body is shaped like a big-end-up square frustum. Hooking teeth are arranged at the four corners of the upper portion of the ladle hooking device body. The push rod is a forge piece. The ladle hooking device body is a casting piece. The pull rod is cast inside the four hooking teeth of the ladle hooking device body. A rib plate is arranged between the pull rod and the ladle hooking device body. The machining method includes the steps that the pull rod is forged; the ladle hooking device body is cast, and the pull rod is cast inside the hooking teeth on the upper portion of the ladle hooking device body; and the rib plate is welded for reinforcement. The forge piece, namely, the pull rod, and the ladle hooking device body are cast into a whole, and therefore the strength of the ladle hooking device is ensured, accidents such as deformation and cracks are avoided, and the process forming is convenient; and the hooking teeth are sharp, wide, large, capable of easily and rapidly hooking away and bringing out the bonded slag of the steel ladle, and therefore the online cold hooking and hot hooking efficiency of the steel ladle is greatly improved, and convenience is provided for maintenance of a ladle opening.

Description

technical field [0001] The invention relates to a sticky slag wrapper, which belongs to the technical field of metallurgical processing. Background technique [0002] During the turnover process of the steel ladle line, due to the process operations such as tapping, slag removal, iron mixing, steel tapping, and slag dumping, sticky slag will be formed on the steel ladle mouth. The sticky slag at the mouth of the iron ladle has different effects in different process environments: 1) Pot dumping station: when the iron is tapped, the ladle sticky slag causes the diameter of the iron ladle to shrink, and it is easy to splash when the iron is tapped and damage the molten iron truck and other equipment; The excess weight of sticky slag in the iron ladle will affect the liquid level of molten iron and the amount of iron, which will cause deviations in smelting; the sticky slag at the mouth of the ladle will be unbalanced, the center of gravity will deviate from the front and back w...

AI Technical Summary

Problems solved by technology

Due to the curved shape of the outside of the hook teeth, the contact surface with the steel cladding wall is small. After the steel slag is caught, the hook will rotate in the ladle, making it difficult to remove the sticky slag from the steel ladle, and the efficiency is low; in addition, the hook pull rod It is relatively slender, although the reinforcement ribs are welded, but because the steel slag is firmly adhered and the weight is heavy (between 1-3t), it is easy to deform or even break after being used many times
