Abstract

The invention relates to an impurity filtering and absorbing flow divider for a tundish. The impurity filtering and absorbing flow divider comprises a tundish body, a permanent layer, an operating layer, a tundish water port, an impurity baffle wall, a turbulence controller and a flow division filter. The impurity filtering and absorbing flow divider is characterized in that the flow division filter is arranged below the impurity baffle wall and comprises a flow division filter body and a plurality of 'V' or 'U'-shaped filter parts, the filter parts are embedded in the flow division filter body and provided with a plurality of through holes, and an adsorption layer is composited on the inner walls of the 'V' or 'U'-shaped filter parts. The impurity filtering and absorbing flow divider has the advantages that specific surface area of the unit size of the flow divider contacting with molten steel is increased to the greatest extent, and collision rate of the impurities and the flow divider is increased. In addition, flow state of the molten steel in the tundish is greatly improved, and the impurities in the molten steel can be further removed.

Description

[0001] technical field [0002] The invention relates to a processing equipment for molten metal, in particular to a filtering and miscellaneous diverter for a tundish. Background technique [0003] The tundish is an intermediate container between the ladle and the crystallizer. Its functions are decompression, steady flow, slag removal, steel storage and diversion, and tundish metallurgy. As the quality requirements for steel products are getting higher and higher, modern metallurgy has higher and higher requirements for the purity of molten steel. Inclusions exist in the steel as an independent item, which destroys the continuity of the steel matrix, increases the inhomogeneity of the structure in the steel, and seriously affects various properties of the steel. And rolling defects, resulting in scrap. Therefore, removing inclusions and improving the cleanliness of molten steel is an important goal in the field of modern smelting technology. The tundish is no longer ju...
