ПроИЗВодСтВо чИСтой СтАЛИ И СоВреМенные огнеуПорные техноЛогИИ Приведен обзор механизмов образования неметаллических включений с участием огнеупоров. Рассмотрены способы управления содержанием неметаллических включений и газов в стальном расплаве с использованием функциональных элементов. Представлена современная технология разливки чистой стали с использованием газоплотного шиберного затвора. Показана эффективность применения сухих смесей для формирования футеровки промежуточного ковша МНЛЗ при производстве флокеночувствительных сталей. Ключевые слова: огнеупоры, чистая сталь, неметаллические включения (НВ), газы в стали.

The article is devoted to assessing the influence of the design of a metal receiver in an intermediate ladle of large capacity slab continuous casting machines on reducing turbulence in flows when the metal stream deviates from the required position during casting. The results of computer simulation of industrial variants of displacing a stream of metal from a steel pouring ladle to an intermediate ladle from the target input point are presented. The distribution of metal flows in the tundish is compared with different designs of metal receivers. Recommendations are given for reducing flow turbulence for the cases considered. Ill. 4. Ref. 2.
