Embodiment Construction
[0087] The present invention is described further below with embodiment and accompanying drawing, but these embodiments are in no way restricting the present invention. Any changes made by those skilled in the art in the implementation of the present invention under the inspiration of this specification will fall within the protection scope of the claims of the present invention.
[0088] see figure 1 , the molten steel conforming to the design of the chemical composition of the present invention is poured directly through the ladle 1, through the ladle long nozzle 2, the tundish 3, the submerged nozzle 4 and the flow distributor 5 in a crystallization chamber that is made of two relatively rotating and capable of rapid cooling. In the molten pool 7 surrounded by the rollers 8a, 8b and the side sealing plate devices 6a, 6b, the molten steel solidifies on the circumferential surface where the crystallization rollers 8a, 8b rotate, and then forms a solidified shell and gradually...
