Особенности производства литых заготовок из медных сплавов

Abstract

Рассмотрены проблемы производства литых заготовок из медных сплавов, содержащих легкоокисляющиеся и легкоиспаряющиеся элементы (Cr, Zr, Cd, Zn, Si и др.). Проанализированы возможные способы ввода легирующих элементов в расплав. Изучены кинетика растворения хрома в расплаве меди и его распределение по сечению и длине слитка при полунепрерывном литье. Кроме того, представлены результаты исследования влияния покровных флюсов в кристаллизаторе при полунепрерывном литье на структуру и свойства сложнолегированных латуней. Полученные в ходе исследования данные положены в основу разработки технологии плавки и полунепрерывного литья медных сплавов. The problems of production of copper alloys containing easily oxidized and volatile elements (Cr, Zr, Cd, Zn, Si etc.) cast bars are considered. The possible methods for adding alloying elements to the melt are analyzed. The kinetics of chromium dissolution in the molten copper and its distribution over the cross section and length of the ingot during a semicontinuous casting is studied. In addition the effect of flux coating in the crystallizer at semicontinuous casting on the structure and properties of complex-brasses is researched. The obtained data are a basis for the development of technology of melting and semicontinuous casting of copper alloys.
