Cantilever type steel ladle drainage sand adding device

Abstract

The invention relates to a cantilever type steel ladle drainage sand adding device, and belongs to the technical field of steelmaking accessory equipment. The cantilever type steel ladle drainage sandadding device comprises a platform, a stand column fixed on the platform and a cantilever rotationally connected with the top end of the stand column, two fixed pulleys are fixed on the cantilever, asteel wire rope is arranged on the two fixed pulleys, and the two ends of the steel wire rope are connected with a counterweight and a sand adding funnel respectively; and the sand adding funnel canbe positioned above a steel ladle nozzle through the rotation of the cantilever, and the axis of the sand adding funnel is overlapped with the axis of the steel ladle nozzle at the vertical position.The cantilever type steel ladle drainage sand adding device can realize accurate addition of drainage sand, ensure the drainage sand to form a reasonable shape, improve the self-opening rate of the steel ladle nozzle, reduce the labor intensity of workers and ensure the normal production rhythm.

Description

technical field [0001] The invention relates to a cantilever type ladle drainage sand adding device, which belongs to the technical field of steelmaking auxiliary equipment. Background technique [0002] In the process of steelmaking production, drainage sand should be added after the ladle replaces the sliding nozzle to ensure the automatic opening of the nozzle, reduce the secondary oxidation of molten steel caused by oxygen drainage when it does not open automatically, and improve the quality of molten steel and slab. The ways of adding drainage sand include throwing type and funnel type. The throwing method is as follows: people stand on the platform, the mouth of the ladle is tilted towards the direction of the person, and artificially throw drainage sand to the eye of the water hole; The environment is poor, and the shape of the added drainage sand is irregular, which affects the self-opening rate of the nozzle. The funnel-type addition method is to add drainage sand...

Problems solved by technology

The throwing method is as follows: people stand on the platform, the mouth of the ladle is inclined towards the direction of the person, and artificially throw drainage sand to the eye of the nozzle; The environment is poor, and the shape of the added drainage sand is irregular, which affects the self-opening rate of the nozzle

The funnel-type addition method is to add drainage sand with a sand-filling funnel behind the furnace, but in the actual production process, when the ladle is hoisted to the position behind the furnace, slag often blocks the nozzle, resulting in the inability to add drainage sand and being forced to change the ladle, affecting normal production rhythm
