Abstract

The utility model relates to a tundish ring argon blowing device, which comprises a main body seal ring, wherein the main body seal ring comprises an inner ring, an outer ring and an annular seal plate, the inner ring is arranged inside the outer ring, a gap exists between the inner ring and the outer ring, the upper end and the lower end between the outer ring and the inner ring are fixedly connected through the annular seal plate, and a plurality of argon blowing holes are uniformly arranged on the annular surface of the inner ring; the utility model discloses a middle package ring blows argon gas for molten steel protection casting process obtains very stable, the control of ideal, thereby has improved the quality of casting product.

Description

Tundish ring argon blowing device

Technical Field

The utility model relates to a middle package ring blows argon gas device.

Background

The problems of high difficulty in protecting and casting molten steel in a continuous casting area and serious nitrogen increase of the molten steel always trouble the molten steel casting process in the continuous casting area, and various methods for protecting and casting are always sought in the process of continuously casting a steel blank, so that the nitrogen increase of the molten steel is reduced as much as possible. The nitrogen increase of the molten steel can cause the reduction of the impact toughness and the deterioration of the welding performance of the steel billet, and the quality of the steel billet is greatly influenced.

SUMMERY OF THE UTILITY MODEL

Problem to prior art existence, the utility model provides a middle package ring blows argon gas device blows argon gas through middle package ring for molten steel protection casting process obtains very stable, ideal control, thereby has improved the quality of cast product.

The utility model provides a technical scheme of above technical problem: the utility model provides a middle package ring blows argon gas device, includes the main part seal ring, the main part seal ring includes inner ring, outer loop and annular shrouding, the inner ring sets up inside the outer loop to and there is the clearance between the outer loop, both ends all pass through about between outer loop and the inner ring annular shrouding fixed connection the inner ring annular is provided with a plurality of on the surface evenly and blows the argon hole.

The utility model discloses the technical scheme who further injects does:

preferably, a detachable connecting pipe communicated with the inside of the outer ring is arranged on one side of the outer ring and is connected with the argon pipeline through the connecting pipe.

Preferably, the upper and lower ends of the inner ring and the outer ring are connected with the two annular closing plates at the upper and lower ends thereof in a sealing way.

Preferably, the inner ring, the outer ring, the annular sealing plate and the connection are all made of stainless steel materials.

Preferably, the number of the argon blowing holes is 4-8.

The utility model has the advantages that: the utility model discloses simple structure, 5 minutes before the pouring basket begins to cast arrange the main part seal ring in the middle of on the ladle cover, then open the pipeline valve who provides argon gas for argon gas passes through the connecting pipe and gets into in the main part seal ring, continuously blows out by blowing the argon hole again, thereby forms an argon that does not have the air and seals the environment around the pouring basket, blows argon gas through the middle ladle ring, makes molten steel protection casting process obtain very stable, the control of ideal, thereby the quality of casting product has been improved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

Example 1

This embodiment provides an argon gas device is blown to middle package ring, the structure is as shown in fig. 1, including the main part seal ring, the main part seal ring includes inner ring 2, outer loop 1 and annular shrouding, the inner ring sets up inside the outer loop, and have the clearance between the outer loop, both ends all are through annular shrouding fixed connection about between outer loop and the inner ring, the annular shrouding of lower extreme seals to be connected about lower extreme and its two on inner ring and the outer loop, evenly be provided with 4 argon gas holes 3 of blowing on the annular surface of inner ring, outer loop one side is provided with rather than the inside connecting pipe 4 dismantled that is linked together, and be connected with the argon gas pipeline through this connecting pipe, the inner ring, the outer loop, annular shrouding and connection all adopt stainless steel.

This embodiment simple structure places the main part seal ring in the middle ladle cover 5 minutes before the pouring of package begins, then opens the pipeline valve who provides argon gas for argon gas passes through the connecting pipe and gets into in the main part seal ring, continuously blows out by blowing the argon hole again, thereby forms an argon that does not have the air and seals the environment around the middle package, blows argon gas through the middle package ring, makes molten steel protection casting process obtain very stable, ideal control, thereby has improved the quality of cast product.

In addition to the above embodiments, the present invention can also have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation are all within the protection scope claimed in the present invention.
