Process and apparatus for the production of rapidly solidified metallic tapes by double-roll system.

摘要

A process and an apparatus for producing rapidly solidified metallic tapes by a double-roll system are disclosed, wherein molten metal is poured into a kissing region defined between a fixed cooling roll and a movable cooling roll through a noule located thereabove and rapidly solidified at the kissing region to form a metallic tape. In this case, pushing forces added to the movable cooling roll by hydraulic cylinders at driving and operational sides are controlled by adding to or subtracting from a standard pushing force an adjusting quantity of the pushing force as a function of a difference between a roll gap at the driving side and a roll gap at the operational side.
