Abstract
A process and apparatus for casting a material into a desired thin strip shape. Molten material is formed into the thin strip shape by an electromagnetic containing and forming process. In a first portion the molten material is shaped into the desired thin strip shape and in a second portion upstream of and communicating with the first portion the molten material is electromagnetically contained in a sump. The sump at a top surface thereof has a substantially larger cross-sectional area as compared to a cross-sectional area of the thin strip shape.
Claims11
In a process for casting a material into a desired thin strip shape, said process comprising:
- electromagnetically containing and forming said material in molten form into a desired shape;
- the improvement wherein:
- said electromagnetic forming and containing step includes:
- shaping electromagnetically a first portion of said molten material into said desired thin strip shape and shaping and containing solely by an electromagnetic field a second portion of said molten material to provide a sump of said molten material upstream of and communicating with said first portion, said sump of molten material having at a top surface thereof a cross-sectional area at least five times greater than a cross-sectional area of said thin strip shape.
