Исследование влияния KCl и NaCl на процесс получения и свойства стали при алюмотермитном восстановлении железа

Abstract

In this paper we study the impact of deactivators on the process of steel production and steel properties in aluminothermic reduction of iron from waste products of metal-working and metallurgical industries. Recovery products contain dross, chips of ferrous and non-ferrous metals. Sodium and potassium chlorides served as deactivators, which reduce melting temperature. It was carried out the calculations for estimations of exothermic reaction temperature in relation to content of deactivators in thermite charge. It were experimentally determined the relationship between steel output and mass concentration of deactivators, as well as the relationship between combustion time and mass concentration of deactivators. Mass concentration of each deactivator, which provide maximal steel output, were found. The analysis of macroscopic structure of samples produced with presence of sodium and potassium chlorides in thermite charge is performed. It has been found experimentally that the amount of gas inclusion in metal structure is reduced in consequence of decreasing of exothermic process intensity.

Изучается влияние деактиваторов на процесс получения и свойства стали при алюмотермитном восстановлении железа из отходов машиностроительных и металлургических предприятий. Продуктами утилизации являются окалина, стружка черных и цветных металлов. В качестве деактиваторов, понижающих температуру плавления, выбраны хлориды натрия и калия. Проведен расчет температур экзотермической реакции в зависимости от количественного содержания деактиваторов в термитной шихте. Экспериментально определены зависимости массового выхода восстановленного металла и времени горения термитной смеси от массового содержания в ней деактиваторов. Найдены массовые концентрации для каждого из деактиваторов, обеспечивающие максимальный выход металла. Проведен анализ макроструктуры образцов, полученных с присутствием в составе термитной шихты хлорида калия и хлорида натрия. Обнаружено, что количество газовых включений в структуре металла понизилось вследствие снижения интенсивности экзотермического процесса.
