Embodiment Construction
[0017] A method of continuous casting of steel, in which at least a pair of striking and vibrating devices are provided on both sides of the short side surface of the casting slab including the unsolidified part when casting a slab with a rectangular cross section, by continuously striking the above-mentioned The short side surface of the slab is cast while applying vibration to the above-mentioned slab, and by hitting the above short side surface, two castings on the long side surface of the above-mentioned slab defined by the following formulas (1) and (2) occur. The intersection point of the curve of the displacement δ(x) in the thickness direction of the billet and the straight line when the displacement δ(x)=0.10mm, adjust the vibration energy, the distance between the guide rollers and the unsolidified thickness to hit the short side surface, so that the above intersection point The distance between the point of intersection far from the origin and the strike position of ...
