Method of repetitiously marking continuously cast metallic strip material

摘要

A method of producing a mark onto a continuously cast metallic strip is disclosed comprising the steps of providing a continuous surface upon which metal strip is cast from a molten metal holding tundish having a nozzle disposed less than about 0.120 inch from the casting surface. The casting surface is cooled and is moved past the nozzle at a rate of about 200 to 10,000 linear surface feet per minute. This method includes providing an impression in the continuous casting surface corresponding to the mark to be produced onto the continuously cast metal strip. Molten metal is continuously fed through the nozzle onto the moving continuous casting surface to produce continuously cast strip thereon, and the cast strip is continuously removed from the casting surface.
