A ladle baking device with adjustable burner

Abstract

The invention relates to a burner ascending and descending adjustable steel ladle baking device. The burner ascending and descending adjustable steel ladle baking device comprises a rack, two rotary arms, a ladle cover and a burner adjusting device. One end of each rotary arm is connected to the rack. The other end of each rotary arm is fixedly arranged on the upper surface of the ladle cover. The burner adjusting device is fixed to the rotary arms and the ladle cover. The burner adjusting device comprises an adjustment and power unit and four regenerative burners. The four regenerative burners are symmetrically fixed to a disk and can move up and down along with the disk. Nozzles of the regenerative burners are inclined at a certain angle, so that burning flames are sprayed into a steel ladle at a certain angle. The flames flow and rotate around the surface of the steel ladle to form a plurality of vortexes when impacting onto the inner wall of the steel ladle, and flowing of hot flue gas is accelerated. According to the burner ascending and descending adjustable steel ladle baking device, the burners can be adjusted to ascend and descend so as to make the temperature in the steel ladle rise to some extent, and the temperature of an inner lining at different heights is more uniform. The working efficiency is improved. The quality of flames and the baking quality are obviously improved.

Description

technical field [0001] The invention relates to a steel-making ladle baking equipment, in particular to a ladle baking device with an adjustable burner. 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 is relatively poor.

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.
