<B> METHOD OF PRODUCTION OF FURNISHED CARBON THICK-SHEED PLATE <D>. The present invention relates to a method for the production of an ultra low carbon cast plate characterized by the addition of Ti to the decarburized cast steel to a carbon concentration of 0.01% by mass or less, additionally adding at least one of Ce. , La, and Nd, and utilize an immersion nozzle to inject the molten steel above a distributor into a continuous casting casting mold while maintaining an inflated air gas flow rate from any location within a range of an upper nozzle. from manifold to the discharge ports of said immersion nozzle at 3 NI (normal liters) / min or less. |
