Description

Electromagnetic metallurgy system for continuous casting tundish

Technical Field

The utility model relates to a metallurgical field of package especially relates to a package electromagnetism metallurgical system in middle of continuous casting in the middle of the continuous casting.

Background

The tundish, as the last refractory vessel that passes before the molten steel solidifies, has a significant impact on the quality of the steel. Firstly, non-metallic inclusions in the steel are eliminated as much as possible in the molten steel state, otherwise they are difficult to remove during solidification of the molten steel. Secondly, the molten steel in the tundish must have a stable and suitable temperature. The temperature of the molten steel is too low, and the molten steel is easy to nodulate and freeze in the tundish, so that the casting is interrupted. The excessive temperature of the molten steel can cause the columnar crystals of the casting blank to be developed, and the defects of center segregation, looseness, cracks and the like are caused. Therefore, the metallurgical function of the tundish constant-temperature casting has great significance for improving the quality of the billet, reducing subcutaneous inclusions and increasing the number of continuous casting furnaces.

In recent years, there are two types of techniques for solving the problem of constant temperature of molten steel in a tundish: one is plasma induction heating technology; one type is channel induction heating technology. However, in the tundish with the constant temperature function, how to remove the fine inclusions in the tundish is still a difficult problem which troubles metallurgical technologists. The traditional solution is that the removal effect of the forms of increasing retaining walls, blocking dams and the like on the impurities is limited if the structure of the tundish is optimized. And electromagnetic stirring with a non-contact tundish is of interest.

For non-contact tundish electromagnetic stirring, the installation of an electromagnetic stirring device is very critical. The tundish shell is generally made of a high-strength steel structure. If the electromagnetic stirring module forming the electromagnetic stirring device is far away from the molten steel, eddy current heating is easily caused on the cladding, the structural strength of the cladding is affected, and potential safety hazards exist. The chinese patent application CN 110000368A proposes to provide a groove on the sidewall of the ladle body to accommodate the electromagnetic stirring device, but a part of steel structure of the ladle shell inside the groove still needs to be spaced between the electromagnetic stirring device and the molten steel to act on the molten steel, and the problem that eddy current heating affects the structural strength of the ladle shell is still easily caused. Moreover, because the thickness of the cladding of the conventional continuous casting tundish is limited, a groove with a larger size cannot be formed, and the size of the electromagnetic stirring module makes the electromagnetic stirring module possibly not be placed in the groove formed in the cladding, so that the electromagnetic stirring module cannot be realized in engineering. If the electromagnetic stirring module is suspended outside the groove, the electromagnetic stirring module is unstable in placement and may bring safety problems. If the thickness of the existing cladding is increased, the cost is greatly increased, and resources are wasted.
