<p>High speed continuous casting device and method, comprising an ingot mold (12) provided with a crystalliser having side-walls between which the product (17) as it cools is suitable to take shape, the product (17) then being sent to a guide, containing and possibly pre-rolling assembly (14) located downstream of said ingot mold (12) and cooperating with secondary cooling means (32), and a system of primary cooling (18) associated with said side-walls, the crystalliser (16) having a longitudinal development with a radius of curvature ('R') having a value at least five times more than the first radius of curvature of the product (17) in the secondary cooling zone located at the outlet of said crystalliser (16), wherein the length (L) of the walls (16a) is more than 1050 mm, so that a progressive and gradual deformation of the product being formed (17) is obtained which prevents tensions, inner cracks and surface lesions from forming thereon.</p> |
