Abstract
A method of and apparatus for continuously casting a high impurity content molten metal in a casting means and the product formed thereby. The method includes the steps of cooling said metal while in said casting means to a temperature resulting in a sound cast bar, extracting the sound cast bar from said casting machine, advancing the sound cast bar to pre-heating means, heating the sound cast bar to a hot-forming temperature, passing the cast bar at a hot-forming temperature from the pre-heating means to a hot-forming means, and hot-forming the cast bar into a wrought product without the cat bar cracking, even when the cast bar has an impurity content of from about 20 to about 200 ppm.
