A continuously cast ingot has a shape of main part in the form of a rectangular prism with flat ends. The ends of ingot have a shape of truncated pyramids, in the case the dimensions of large bases, which are adjacent to the main part of ingot, are equal to the cross-section of the main part of ingot, and the dimensions of smaller bases are calculated according to the formula:where Hk - height of the smaller base of ingot end, mm;H3 - height of the ingot, mm;D - rolling diameter of the roll, mm;α - maximum angle of capture of metal by rolls, rad;&Dgr;h - maximum possible value of absolute reduction, mm;γ - angle of inclination of narrow sides of the pyramid, mm. |
