Description

Automatic suspension device for tundish

Technical Field

The utility model belongs to the technical field of the metallurgy, especially, relate to an automatic suspension ware of middle package.

Background

At present, with the rapid development of scientific technology, higher requirements are put forward on various materials. In particular, the requirements on the quality of steel are higher and higher, which requires higher and more strict requirements on the quality of steel. The whole society also puts higher demands on economic development, and requires high-quality development! Therefore, the requirements on the quality and the purity of the molten steel are more strict than the prior requirements.

At present, the electromagnetic stirring is only added at the blank drawing position at home and abroad to process impurities and bubbles in the molten steel, but the segregation phenomenon inside the steel is generated. Cause the internal material of the steel to be uneven;

(1) the electromagnetic stirring procedure is complicated, and the material segregation phenomenon occurs;

(2) to obtain good steel, the molten steel must be processed in place to obtain good material!

The difficulty in solving the above problems and defects is: electromagnetic stirring is the last remedy added before continuous casting, but the process is complex! Moreover, the segregation phenomenon occurs in the steel. And the automatic middle-ladle suspension device is time-saving, convenient and economic.

The significance of solving the problems and the defects is as follows: the impurities in the molten steel are treated as early as possible, which is beneficial to improving the quality of steel products! Is convenient for automatic control. The invention creates great wealth for steel mills, and has important significance for high-quality development of society.

SUMMERY OF THE UTILITY MODEL

To the problem that prior art exists, the utility model provides an automatic suspension ware of middle package.

The utility model discloses a realize like this, the automatic suspension ware of middle package has:

the tundish comprises a tundish body, wherein an impact plate is arranged at the bottom of the inner side of the tundish body, and a tundish automatic suspension device is arranged on the upper side of the impact plate (or the impact plate and the tundish automatic suspension device are prefabricated into a whole);

the impact plate in the tundish body or the impact plate and the tundish automatic suspension device are prefabricated into a whole. Three holes are arranged on the upper surface of the steel tube, so that the molten steel can flow clockwise (or anticlockwise).

Three through holes are formed in the outer wall of the automatic tundish suspender at different angles, and the through holes are tangent to the outer wall of the automatic tundish suspender.

Furthermore, a brick cup is embedded at the other end of the bottom of the tundish body, and a tundish nozzle is embedded in the brick cup.

Combine foretell all technical scheme, the utility model discloses the advantage that possesses and positive effect are: the utility model discloses well packet of automatic suspension ware passes through the molten steel in impurity and the bubble and flows the effect that forms centrifugal force at the package internal rotation to the molten steel, suspends impurity and bubble in the molten steel. The steel slag is scraped out by a tundish slag scraping plate, and the steel slag and the bubbles of the molten steel are processed in time! Thereby greatly improving the purity of the molten steel! And plays a role in automatically stirring the molten steel. It also plays a great role in improving the quality of steel. Thereby directly reducing the sand hole and microcrack action of the steel and improving the quality of the steel.
