а криволинейный участок рабочей поверхности выполнен по зависимостиand the curved section of the working surface is made according to
Figure 00000002
,
Figure 00000002
,
где y - разность между толщиной узкой стенки вверху кристаллизатора и на расстоянии x от верха кристаллизатора, мм;where y is the difference between the thickness of the narrow wall at the top of the mold and at a distance x from the top of the mold, mm; x - расстояние от верха кристаллизатора, мм;x is the distance from the top of the mold, mm; a - безразмерный коэффициент, зависящий от свойств разливаемой марки стали, режима и условий разливки, размера сечения заготовки и равный 0,0005...0,025;a is a dimensionless coefficient depending on the properties of the cast steel grade, casting conditions and conditions, the size of the billet cross section and equal to 0.0005 ... 0.025; b - коэффициент, зависящий от свойств разливаемой марки стали, режима разливки, размера сечения заготовки и равный 0...1000 мм;b is a coefficient depending on the properties of the cast steel grade, the casting mode, the size of the cross section of the workpiece and equal to 0 ... 1000 mm; ω - безразмерный коэффициент поворота рабочей поверхности, равный 0...0,025;ω is the dimensionless coefficient of rotation of the working surface, equal to 0 ... 0,025; l1 - длина прямолинейного участка узкой стенки, мм,l 1 - the length of the rectilinear section of the narrow wall, mm, при этом длина l1 прямолинейного участка составляет 0,05...0,7 длины кристаллизатора,the length l 1 of the rectilinear section is 0.05 ... 0.7 of the length of the mold, отличающийся тем, что в области боковых ребер узкой стенки выполнены выборки, имеющие следующие характеристики:characterized in that in the region of the side ribs of the narrow wall, samples are made having the following characteristics: выборка начинается на расстоянии 0,05...0,7 длины кристаллизатора от верха узкой стенки и продолжается до низа кристаллизатора;sampling begins at a distance of 0.05 ... 0.7 of the length of the mold from the top of the narrow wall and continues to the bottom of the mold; ширина выборки (расстояние от границы выборки на рабочей поверхности до бокового торца узкой стенки) непрерывно возрастает при удалении от верха кристаллизатора;the width of the sample (the distance from the border of the sample on the working surface to the side end of the narrow wall) increases continuously with distance from the top of the mold; глубина выборки постоянна или переменна по ее ширине и длине в зависимости от технологических параметров разливки и свойств разливаемой стали;sampling depth is constant or variable in its width and length depending on the technological parameters of the casting and the properties of the cast steel; длина выборки составляет 0,3...0,95 длины кристаллизатора.the sample length is 0.3 ... 0.95 of the length of the mold.
