A kind of iron and steel cladding slag hooker and its processing method

Abstract

The invention discloses a steel cladding slag hooking device, which comprises a pull rod and a hook main body, a long rope threading hole is arranged in the middle of the upper part of the pull rod, and a stepped platform is arranged at the bottom of the pull rod; the whole body of the hook hook is It is a truncated square cone with a large top and a small bottom, with hook teeth at the four corners of the upper part, the hook teeth are triangular pyramids; the tie rod is a forging, the main body of the hook is a casting, and the tie rod is cast on the four corners of the hook main body. The inner side of each hook tooth; a rib plate is arranged between the tie rod and the main body of the hook; the processing method of the present invention includes: forging the tie rod; Reinforced by welded ribs. The present invention adopts the forging tie rod and the hook main body to be cast into one body, which ensures its strength and avoids accidents such as deformation and breakage. The sticky slag greatly improves the efficiency of online cold hooking and hot hooking of steel ladles, and provides convenience for the maintenance of the ladle mouth.

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
