Automatic slag stopping cap adding device for tapping hole and using method

Abstract

The invention discloses a tapping hole automatic slag stopping cap adding device and a using method, the tapping hole automatic slag stopping cap adding device comprises a carrier, a telescopic assembly and a pushing device, the fixed end of the telescopic assembly is arranged on the carrier, and the telescopic end of the telescopic assembly is hinged to the rear section of the pushing device; the stroke of the telescopic end of the telescopic assembly is adjusted to change the height and posture of the pushing device, so that a slag stopping cap located at the front end of a pushing rod in the pushing device can be aligned with a tapping hole; the pushing device is provided with a driving device used for driving the pushing rod to stretch out and draw back in the moving direction of the pushing device, so that the pushing rod can push the slag stopping cap aligned with the steel tapping hole into the steel tapping hole. The method effectively improves the mechanization level of adding the slag stopping cap into the converter, reduces the labor intensity of workers, avoids high-temperature grilling, and has important practical significance for improving the production image of the iron and steel industry.

Description

technical field [0001] The present application relates to the technical field of converter steelmaking, and in particular, to a device for automatically adding a slag cap to a tapping hole and a method of using the same. Background technique [0002] The converter is the main equipment for domestic steelmaking production. After the converter steelmaking is completed, the molten steel in the converter needs to flow into the ladle. This process is generally called converter tapping. When the converter is tapping, the slag entering the ladle from the converter should be controlled as much as possible, so as to reduce the phenomenon of molten steel returning to phosphorus and worsen the quality of the molten steel. [0003] At present, mechanized operation has been achieved by adding slag blocking rods, slag blocking plugs, slag blocking balls and other slag blocking devices to the tapping hole in the furnace at the end of the tapping stage, but inserting the slag blocking cap i...

Problems solved by technology

[0004] Since the converter body is covered by a large amount of red hot slag, the operator needs to endure high temperature roasting when doing the above work, especially in summer, the high temperature roasting will be particularly obvious. It also takes a lot of physical strength to put it into the taphole, especially in some abnormal situations, such as when the slag retaining device is on the inside of the taphole and is closely sintered with the furnace lining under the action of slag, sometimes it takes multiple people to work together. seriously affect the working experience of steelmaking
