Problems solved by technology

At present, the relatively mature mechanism mainly has two burners arranged symmetrically, and the burners are arranged perpendicular to the cover. When the gap distance between the cover and the cover is constant, the burner cannot move up and down.
This baking method makes the ladle unable to reach a higher temperature field, and the temperature distribution between the top and bottom of the ladle is uneven, the temperature difference is large, and the baking quality is relatively poor.

Abstract

The invention relates to a steel ladle baking device with a lifting-adjustable ladle cover outer ring. The steel ladle baking device comprises a rack, rotating arms, a ladle cover, heat accumulation type burners and a ladle cover outer ring adjusting device. The two rotating arms are arranged, one ends of the rotating arms are connected to the rack, and the other ends of the rotating arms are connected to the ladle cover. The four heat accumulation type burners are arranged and are symmetrically fixed to the ladle cover. The ladle cover outer ring adjusting device is fixed to the rotating arms and the ladle cover, and the ladle cover outer ring can move vertically so that the distance between the lower end of the ladle cover outer ring and the gap of a ladle opening can be controlled within 200 mm. Injection openings of the heat accumulation type burners incline by a certain angle, so that combustion flames have a certain angle when injected into the steel ladle, the flames flow and rotate around the surface of the ladle wall when impacting the inner wall of the steel ladle to form multiple vortexes, and flowing of hot flue gas is accelerated. By means of the steel ladle baking device, the rotating arms can drive the ladle cover and the burners to move vertically, the ladle cover outer ring moves so that the air inlet amount cannot change, a temperature field in the steel ladle is improved to a certain degree, and the lining temperature in all height directions is more uniform.

Description

technical field [0001] The invention relates to a steel-making ladle baking device, in particular to a ladle baking device with an adjustable lift of the outer ring of the cover. Background technique [0002] The ladle is a container for molten steel, mainly for storage and transfer of molten steel, and also for heat storage and heat preservation. The most basic purpose of ladle baking is to reduce the tapping temperature at the end of the previous process and increase the service life of the ladle. At present, the relatively mature mechanism mainly has two burners arranged symmetrically, and the burners are arranged perpendicular to the cover. When the gap distance between the cover and the cover is constant, the burner cannot move up and down. This baking method makes it impossible to reach a higher temperature field in the ladle, and the temperature distribution between the top and bottom of the ladle is uneven, the temperature difference is large, and the baking quality ...
