Embodiment 3

[0047] The structure of metallurgical ladle device with vacuum shell is as follows: image 3 As shown, the structure of the metallurgical ladle is the same as in Embodiment 1, the difference is that: the bottom of the metallurgical ladle is provided with a bottom blowing device hole 14 and a metal liquid flow hole 19, and the structure of the vacuum shell is the same as in Embodiment 1, the difference is that:

[0048] (1) An isolation tube 24 is arranged around the hole 14 of the bottom blowing device and the metal liquid flow hole 16, and two through holes are arranged at the bottom of the barrel wall. The bottom of each isolation tube 24 communicates with a through hole respectively, and the isolation tube 24 The top is connected to the bottom surface of the metallurgical cladding 1, so that the bottom blowing device hole 14 and the metal liquid flow hole 16 are isolated from the vacuum chamber;

[0049] (2) The distance between the inner surface of the cylindrical side wal...

Abstract

The invention discloses a metallurgical ladle device with a vacuum shell and belongs to the technical field of metallurgical equipment. The vacuum shell is arranged on the outer wall of a metallurgical ladle shell; the top of the vacuum shell is fixedly connected with the top of the metallurgical ladle shell; a gap between the inner wall of the vacuum shell and the outer wall of the metallurgicalladle shell forms a shell vacuum chamber; and the air pressure in the vacuum chamber is 1 to 5Pa. The device has the advantages of low manufacturing cost, long service life, high heat insulation performance, working stability and the like, is suitable for metallurgical ladle, such as foundry ladle, steel ladle or tundish, and can also be suitable for metal liquid ladle or a metal liquid tank in the non-ferrous metallurgical industry.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, in particular to a metallurgical ladle device with a vacuum shell. 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] The ladle is a container for storing molten steel, and it is also an integral part of the refining equipment; molten steel will lose a lot of heat during the transfer and casting process after it is loaded into...
