Присутствие данных неметаллических включений негативно влияет на чистоту жидкой стали, механические свойства, затрудняет разливку вследствие затягивания сталеразливочной фурнитуры. Модифицирование включений оксида алюминия кальцием способствует образованию жидких алюминатов кальция, что приводит к ускорению их удаления из металла ввиду более высокой скорости всплытия. Обладая высоким сродством к сере, кальций связывает ее, образуя сульфиды, тем самым уменьшая вредное влияние серы и снижая анизотропию свойств стали при дальнейшей прокатке. Для обработки стали кальцием используют инжекционные проволоки с кальцийсодержащим наполнителем. В качестве наполнителя могут быть использованы электролитический кальций, силикокальций, алюмотермический кальций, феррокальций. В данной работе описаны результаты проведенных испытаний кальцийсодержащей проволоки с наполнителем из электролитического кальция и силикокальция. Показано, что расход кальция при использовании силикокальциевой проволоки в среднем на 35 % выше в сравнении с кальциевой инжекционной проволокой с наполнителем из электролитического кальция. Проведена оценка коэффициента усвоения кальция для различных сортаментов сталей при использовании кальцийсодержащих проволок разных дизайнов и наполнителя. Выполнен анализ разливаемости стали, где в качестве определяющего параметра рассмотрена зависимость изменения положения штока стопора промежуточного ковша от содержания кальция в металле по пробе с установки непрерывной разливки стали. Установлено, что проволока с наполнителем из электролитического кальция показывает более эффективный результат в сравнении с силикокальциевой проволокой.</p></abstract><trans-abstract xml:lang="en"><p>Aluminum is one of the most common deoxidizers; when it is used in the melt, refractory inclusions of alumina are formed. The presence of these non-metallic inclusions negatively affects the purity of liquid steel, mechanical properties, makes casting difficult due to tightening of the steel-pouring fittings. The modification of alumina inclusions with calcium promotes the formation of liquid calcium aluminates, which leads to an acceleration of their removal from the metal due to a higher ascent rate. Having a high affinity for sulfur, calcium reduces its harmful effect by binding it with the formation of calcium sulfides, reducing the anisotropy of steel properties during further rolling. For steel treatment with calcium, injection wires with a calcium-containing filler are used. As a filler can be used: electrolytic calcium, silicocalcium, aluminum-tremic calcium, or ferrocalcium. The paper describes results of the tests carried out on a calcium-containing wire filled with electrolytic calcium and silicocalcium. It is shown that the consumption of calcium when using silicocalcium wire is on average 35 % higher in comparison with calcium injection wire filled with electrolytic calcium. The calcium recovery rate for different steel grades was evaluated using calcium-containing wires of different designs and filler. In this work, the steel pourability was analyzed. As a determining parameter, dependence of change in position of the tundish stopper rod on calcium content in the metal was considered in the sample from CCM. It was established that a wire filled with electrolytic calcium shows a more effective result in comparison with a silicocalcium wire.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>внепечная обработка стали</kwd><kwd>кальцийсодержащая инжекционная проволока</kwd><kwd>кальций</kwd><kwd>электролитический кальций</kwd><kwd>силикокальций</kwd></kwd-group><kwd-group xml:lang="en"><kwd>steel ladle treatment</kwd><kwd>calcium-containing injection wire calcium</kwd><kwd>electrolytic calcium</kwd><kwd>silicocalcium</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wasai K., Mukai K., Miyanaga A.
