DEVICE FOR VACUUM REFINING OF MOLTEN METAL

摘要

A device for vacuum-refining of molten metal, comprising a vacuum chamber and an electromagnetic pump with an annulus-section line to which metal feed and discharge pipe lines are connected. The latter is coupled with the central portion of the annulus-section line. For pouring vacuumed metal into a foundry mould provision is made for a metal pouring pipe line connected to the metal discharge pipe line. The device envisages a higher degree of metal refining to free it from harmful impurities and a possibility of pouring metal directly into foundry moulds.
