Способ изготовления заготовок и блюмов из стали непрерывной разливки позволяет получить настолько длинные продукты, чтобы их можно было непосредственно транспортировать на чистовой прокатный стан. Указанный способ включает этап деформации профиля жидкого ядра, касающегося поперечного сечения отливки и вызывающего редуцирование этого поперечного сечения, при этом его периметр остается одинаковым. Деформацию профиля осуществляют в зоне, находящейся между точкой S, последней точкой на оси разливки Х-Х, где еще присутствует перегретая жидкость, и точкой L, в которой отливка уже полностью затвердела. Предпочтительнее деформацию профиля осуществлять между точками, находящимися в пределах от 10 до 80% концентрации твердых зерен в жидкой массе. Устройство содержит средства для установки по крайней мере одного из секторов, образующих линию валков возле противолежащего сектора, в по крайней мере одной плоскости, содержащей ось разливки в соответствующей деформации профиля зоне.The method of manufacturing billets and blooms from continuous casting steel allows us to obtain products that are so long that they can be directly transported to the finishing rolling mill. This method includes the step of deforming the profile of the liquid core, relating to the cross section of the casting and causing the reduction of this cross section, while its perimeter remains the same. The profile deformation is carried out in the zone located between point S, the last point on the casting axis XX, where the superheated liquid is still present, and point L, at which the casting has already completely hardened. It is preferable to deform the profile between points in the range from 10 to 80% of the concentration of solid grains in the liquid mass. The device comprises means for placing at least one of the sectors forming a line of rolls near the opposite sector in at least one plane containing the axis of the casting in the corresponding deformation of the profile zone.
