Abstract
A start-up method and apparatus for continuous casting of molten metal into a cast strip product includes initially casting a start-up alloy having sufficient strength, flexibility and casting surface release properties to achieve steady state casting conditions. A target alloy follows the start-up alloy being cast to produce a cast strip product of the target alloy composition. A start-up alloying vessel is disposed between the source of the target alloy and the casting apparatus to facilitate introduction of a start-up alloy into the casting process or formulation of a particular start-up alloy for initiation of the continuous casting operation.
Claims10
A method of continuous casting a molten metal comprising the steps of:
- a) providing a molten metal having a first composition;
- b) providing a quantity of a start-up molten metal of a second composition;
- c) initially continuously casting said start-up molten metal on to a moving unitary chill surface to establish steady state casting;
- d) continuously casting said molten metal subsequent to said start-up molten metal being cast onto said moving unitary chill surface;
- and
- e) recovering a cast strip product comprising a portion of said start-up molten metal having said first composition with the balance being a cast strip product having said second composition.
