Converter slagging device and method for controlling converter slagging

Abstract

The invention discloses a converter slagging device and a method for controlling converter slagging, and the device comprises a slagging runner in a platy structure and a retaining wall, wherein the slagging runner is aslant fixed on a buggy ladle and is arranged in front of the steel ladle on a converter tapping direction, the slagging runner comprises a first surface back to the surface of the buggy ladle and a second surface facing to the surface of the buggy ladle, and the slagging runner comprises a first end and a second end lower than the first end along the height direction; and the retaining wall comprises a first retaining wall and a second retaining wall respectively fixed on the left side and the right side of the first surface of the slagging runner to limit the channel for the flowing of converter slag. The phenomenon that steel slag falls in the ladle in the process of reducing the titling angle of the converter after the molten steel in the converter is completely discharged, the quality of the molten steel is improved, and the steel slag is prevented from splashing to the buggy ladle to burn the buggy ladle and the support equipment.

Description

technical field [0001] The invention belongs to the technical field of slag blocking in converter tapping. Specifically, the invention relates to a converter slag lowering device and a method for controlling converter slag lowering by using the device. Background technique [0002] In the prior art, a tapping slag blocking device is used to carry out the slag blocking operation for converter tapping. In the process of reducing the tilting angle of the converter when the molten steel is exhausted at the end of tapping, the ladle car needs to move with the change of the tilting angle of the converter to receive the steel slag flowing from the tapping hole and prevent the high temperature steel slag from burning the steel Chartered vehicles and their supporting equipment. The steel slag flowing into the ladle will react violently with the carbon in the molten steel to cause boiling, and the steel slag overflowing the ladle will burn out the supporting equipment of the ladle ca...

AI Technical Summary

Problems solved by technology

The steel slag flowing into the ladle will react violently with the carbon in the molten steel to cause boiling, and the boiling slag overflowing the ladle will burn out the supporting equipment of the ladle car, hindering the smooth progress of the converter tapping

In addition, handling the ladle cars welded to the cooled steel slag also increases the labor intensity of the on-site workers
