| abstract | (57) [Summary] [Object] The present invention provides a casting method for refining the solidification structure of steel. [Structure] When casting steel, the average grain size is 1 in the temperature range from liquidus temperature + 100 ° C or lower to solidus temperature or higher. The total amount of tantalum oxide and niobium oxide of μm or less is 0.2 to Add 2 wt% and solidify, or add tantalum oxide and niobium oxide with an average particle size of 1 μm or less in a total amount of 0.02 to 1 wt% and at the same time stir molten steel at a rotation speed of 5 to 1000 rotations per minute. Then, a method for casting steel is characterized in that a fine solidified structure is generated by solidifying after stirring is stopped. [Effect] If the steel ingot according to the present invention is used, it is possible to manufacture steel having excellent strength and toughness by direct rolling. |
