Anti-deformation slag slide plate device for converter

By reserving expansion gaps at the joints of the chute plates and reinforcing the structure with U-shaped clips, square steel bars, and pads, and connecting them with the frame steel using "7"-shaped hooks, the problems of thermal deformation and stress concentration of the chute plates were solved, thus improving the stability of the chute plates in use.

AI Technical Summary

⚠Technical Problem

During the converter steelmaking process, the slag chute is deformed due to the adhesion of hot steel slag, and the uneven heating of the bolted connection causes stress concentration, which affects the overall performance of the slag chute.

⚗Method used

The joints between the slag chute plates are designed to allow for thermal expansion gaps, and the strength of the slag chute plates is enhanced by U-shaped clips, square steel bars, and pads. The plates are connected to the frame steel by "7"-shaped hooks to prevent thermal deformation and stress concentration.

🎯Benefits of technology

It effectively prevents thermal deformation of the chute plate, enhances the overall performance of the chute plate, and avoids the effects of uneven heating and stress concentration on bolted connections.

Abstract

This utility model belongs to the field of iron and steel metallurgical technology, and particularly relates to an anti-deformation slag chute device for converters. A 5mm thermal expansion gap is reserved at the joint between slag chute plates. Multiple sets of U-shaped clips are welded to the back of each slag chute at the joint end. The multiple sets of U-shaped clips on adjacent slag chute plates are of the same height and are arranged parallel from top to bottom. Each set of U-shaped clips contains multiple U-shaped clips, which are arranged parallel from left to right. Both ends of the U-shaped opening of each U-shaped clip are fixed vertically. Square steel bars are inserted into the multiple sets of U-shaped clips at the joint of adjacent slag chute plates, and the square steel bars are fixed to the back of the slag chute plate. A 1mm sliding gap is reserved on one side between the U-shaped clip and the square steel bar. Multiple rows of pads are fixed to the back of the slag chute plate with bolts, and the rows of pads are arranged parallel from top to bottom. The multiple sets of U-shaped clips, square steel bars, and pads enhance the strength of the slag chute plate itself, resist the deformation stress generated by heat, and prevent thermal deformation of the slag chute plate.
