Problems solved by technology

[0006] However, since both the high alkalinity flux and the high silica rice husk flux have been used to achieve the above effects, the cost of using the flux increases, and this may lead to an increase in the cost of the casting process

Abstract

The present invention relates to a flux supplied to an upper portion of a molten steel in a tundish, and a casting method using the same. The flux is able to totally be displaced with SiO2-based and Al2O3-based flux conventionally used in accordance with a tundish operation environment, or is able to be used by being partially mixed with a first composition and a second composition, the first composition including 45 to 60 wt% of SiO2 based on a total 100 wt% of the flux and 20 to 40 wt% of MgO, the second composition containing the component controlling reoxidization of the molten steel and the melting point and viscosity of the flux. That is, by providing the flux having SiO2 and MgO as the basic composition, it is possible to increase the thermal insulation of the molten steel, suppress the reoxidation of the molten steel, absorb the inclusion easily, and minimize the melting damage of refractory materials. Accordingly, the treatment of the molten steel in the tundish is easy, and the quality of the manufactured steel product can be increased.

Description

technical field [0001] The present disclosure relates to a flux and a casting method using the same, and more particularly, to a flux that can improve the quality of molten steel by being added to a tundish and a casting method using the same. Background technique [0002] Generally, a continuous casting process of casting molten steel into a slab is a process in which molten steel contained in a ladle after completion of secondary refining (in a state in which molten steel is temporarily stored in a tundish) is supplied to a mold and cooled , to manufacture semi-finished products in various shapes, such as slabs, blooms, billets and beam blanks for I-beams. [0003] In the tundish during the continuous casting process, the molten steel is finalized before casting and, to ensure the cleanliness of the molten steel, a flux is added on top of the molten steel to remove inclusions from the molten steel and to inhibit re-oxidation. [0004] Overbased fluxes and high silica rice...
