Abstract

Стержень (22) стопора для непрерывной разливки расплавленного металла имеет основную часть (22-3) стержня стопора и наконечник (22-1) стержня стопора на нижнем конце основной части стержня стопора. Наконечник (22-1) стержня стопора определяет наружную поверхность в форме усеченного конуса (22-1а), которая заканчивается носовой частью с выемкой (22-1b). Наиболее предпочтительно, если носовая часть с выемкой имеет криволинейную поверхность (например, сферический сегмент), но могут быть использованы и некриволинейные поверхности (например, призматические, пирамидальные, трехгранные и четырехгранные поверхности). Наиболее предпочтительно, если наружная поверхность в форме усеченного конуса (22-1а) наконечника стержня стопора образует с соответствующей горизонтальной поверхностью угол θ, который является достаточно большим, чтобы повысить скорость протекающего расплавленного металла, для того чтобы уменьшить толщину граничного слоя, примыкающего к поверхностям сопла и наконечника стержня стопора, и минимизировать осаждение включений на них. Предпочтительно, если угол θ больше чем 70° и меньше чем 85°.The stopper rod (22) for continuous casting of molten metal has a stopper rod main part (22-3) and a stopper rod tip (22-1) at the lower end of the stopper rod main part. The tip (22-1) of the stopper bar defines a frusto-conical outer surface (22-1a) that ends with a recessed nose (22-1b). Most preferably, the notched nose has a curved surface (eg, a spherical segment), but non-curved surfaces (eg, prismatic, pyramidal, triangular and tetrahedral surfaces) can be used. Most preferably, the frusto-conical outer surface (22-1a) of the stopper rod tip forms an angle θ with the corresponding horizontal surface that is large enough to increase the velocity of the flowing molten metal in order to reduce the thickness of the boundary layer adjacent to the nozzle surfaces and the tip of the stopper rod, and minimize the deposition of inclusions on them. Preferably, the angle θ is greater than 70 ° and less than 85 °.
