Claims (1)

Способ легирования стали легкоплавкими элементами, включающий присадку легирующих материалов в центровой литник, отличающийся тем, что, с целью обеспечения равномерности распределения легкоплавких элементов и экологических требований при металлургическом переделе, легирующие материалы начинают вводить в центровой литник после наполнения изложницы на 50 - 90% высоты отливаемого слитка, а заканчивают вводить в конце разливки одновременно с началом заливки последней порции металла, равной 50 - 180% массы металла в литниковых каналах после окончания разливки, причем до начала введения легкоплавких элементов в изложницу присаживают теплоизолирующий материал с теплопроводностью не более 0,20 ккал/м•ч•град (0,838 Дж/м•ч•град) в количестве, обеспечивающем толщину слоя на поверхности металла в изложнице не менее 10 мм.The method of alloying steel with fusible elements, including the addition of alloying materials to the center gate, characterized in that, in order to ensure uniform distribution of fusible elements and environmental requirements during metallurgical processing, alloying materials begin to be introduced into the center gate after filling the mold with 50 - 90% of the cast height ingot, and they finish entering at the end of the casting simultaneously with the start of pouring the last portion of metal equal to 50 - 180% of the mass of metal in the gating channels after approx the end of the casting, and before the introduction of fusible elements into the mold, heat-insulating material with a thermal conductivity of not more than 0.20 kcal / m • h • deg (0.838 J / m • h • deg) is seated in an amount that ensures the layer thickness on the metal surface in the mold is not less than 10 mm.
