Description
ные стороны и направлен параллельно касательным к окружности днища ковша.and are parallel to the tangents to the bucket circumference.
На чертеже показан ковш.The drawing shows a bucket.
Газ в ковш 1 подают через пористую вставку 2, установленную в стакане 3 с обмазкой на боковых поверхност х. Под днип1,е вставки подведена трубка 4 дл подачи газа. Поверхности 5 вставок выполнены скошенными к зеркалу металла, а наклон этих поверхностей обращен в противоположные стороны и направлен параллельно касательным к окружности дниша ковша.Gas is supplied to the ladle 1 through the porous insert 2 installed in glass 3 with coating on the side surfaces. Under the bottom of the insert, tube 4 is supplied for gas supply. The surfaces of the 5 inserts are bevelled toward the metal mirror, and the inclination of these surfaces is directed in opposite directions and directed parallel to the tangents to the bottom circumference of the ladle.
В ковше устанавливают две пористые пробки , имеюшие скос 5-15° с диаметрально противоположных сторон. При подаче газа через пробки он принимает в металле веерообразную форму и наблюдаетс вращение металла. Пульсирующа подача газа исключает образование полостей воздуха, что улучшает перемешивание газа с металлом.In the bucket install two porous plugs, which have a bevel of 5-15 ° from diametrically opposite sides. When gas is supplied through the plugs, it assumes a fan-shaped shape in the metal and metal rotation is observed. A pulsating gas supply eliminates the formation of air cavities, which improves the mixing of gas with metal.
Работает устройство следующим образом.The device works as follows.
По трубопроводу подают инертный газ, например аргон. Газ по трубопроводам 6 и трубке 4 через пористую вставку 2 поступает в металл . Поток газов принимает веерообразную форму, пронизывает толшу металла, а горизонтальные составл юшие потока газов, образуюшиес за счет наклона вставок на поверхности 5, придают сло м металла врашательное движение, что значительно улучшает степень перемешивани пузырьков газа с металлом и шлаком. Это способствует улучшению 5 качества металла.The pipeline serves an inert gas, for example argon. Gas through pipelines 6 and tube 4 through porous insert 2 enters the metal. The gas flow takes on a fan-shaped shape, penetrates the metal thicknesses, and the horizontal components of the gas flow formed by tilting the inserts on the surface 5 give the metal layers a decorative movement, which significantly improves the degree of mixing of gas bubbles with the metal and slag. This improves the quality of the metal.
