регрева, что в свою очередь интенсифицирует процесс перегрева металла. Интенсификаци  перегрева также достигаетс  в результате активного перемешивани  металла. Кроме того, при вращении миксера жидкий металл захватываетс  выступающими элементами, а затем мелкими струйками и капл ми стекает в ванну. При падении жидкий металл подвергаетс  воздействию гор чих газов и перегреваетс . Кольцевой паз 15 служит дл  полного слива жидкого металла.heating, which in turn intensifies the process of metal overheating. Intensification of overheating is also achieved as a result of active mixing of the metal. In addition, when the mixer is rotated, the liquid metal is captured by protruding elements, and then in small streams and drips into the bath. When falling, the liquid metal is exposed to hot gases and overheats. The annular groove 15 serves to completely drain the liquid metal.

Приведенное соотношение между глубиной каналов и диаметром миксера  вл етс  оптимальным . Уменьшение этого соотношени  приводит к уменьшению поверхности нагрева, а увеличение-к развитию выступающих элементов , что снижает их жесткость и прочность.The ratio between the depth of the channels and the diameter of the mixer is optimal. A decrease in this ratio leads to a decrease in the heating surface, and an increase in the development of protruding elements, which reduces their rigidity and strength.

Миксер может работать как на холодном, так и на гор чем воздухе. Дл  подогрева воздуха может быть использовано тепло отход щихThe mixer can work both on cold, and on hot than air. Heat can be used to heat the air.
