Novel metallurgical ladle device with vacuum shell and using method thereof

Abstract

The invention discloses a novel metallurgical ladle device with a vacuum shell and a using method thereof. The novel metallurgical ladle device comprises an inner container; the shell is arranged outside the inner container and fixedly connected with the inner container; a movable cover is arranged at the top of the shell and matched with the shell; a locking mechanism is arranged between the movable cover and the shell; a vacuum mechanism is arranged on the front side of the shell; the locking mechanism comprises a movable hook; the movable hook is arranged on the outer side of the movable cover and hinged to the movable cover; and the shell is sleeved with a fixing ring. One of short rods is pulled to move upwards through a movable column, so that the two short rods pull a connecting rod towards the movable column, then the hinged movable hook rotates so that the bottom end of the movable hook can be separated from a limiting groove in the bottom of the fixing ring, and therefore the buckling relation between the movable hook and the fixing ring is relieved, and then a hanging ring continues to be pulled, so as to separate the movable cover from the shell.

Description

technical field [0001] The invention relates to the field of metallurgical ladles, in particular to a novel metallurgical ladle device with a vacuum shell and a method for using the same. Background technique [0002] As iron and steel producers pay more attention to the quality and cost of steel production, higher requirements are put forward for metallurgical ladles such as ladles, tundishes, and ladles; The liquid container, especially the secondary refining and continuous casting of the ladle, requires the molten steel to stay longer in the ladle and lower the temperature; in order to meet the strict requirements of the process on materials, it is generally realized by high-end refractory materials, but there is still a temperature drop problems such as large size and high cost. [0003] At present, the metallurgical ladle needs to be equipped with a cover during use to keep the metallurgical ladle warm and reduce the temperature drop. However, the existing ladle is cum...

AI Technical Summary

Problems solved by technology

[0002] As iron and steel producers pay more attention to the quality and cost of steel production, higher requirements are put forward for metallurgical ladles such as ladles, tundishes, and ladles; The liquid container, especially the secondary refining and continuous casting of the ladle, requires the molten steel to stay longer in the ladle and lower the temperature; in order to meet the strict requirements of the process on materials, it is generally realized by high-end refractory materials, but there is still a temperature drop Large and costly issues

[0003] At present, the metallurgical ladle needs to be equipped with a cover during use to insulate the metallurgical ladle and reduce the temperature drop. However, the existing ladle is cumbersome to operate and needs to make specific capping equipment, which increases the cost of use.
