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.

Abstract: A molten metal filter effectiveness indicator comprising means for detecting the molten metal level on at least one side of a molten metal filter, and method.

Abstract: Disclosed is an apparatus for and a method for more uniform and rapid cooling of molten metal, which is continuously cast into a wheel-band machine, by dispersing a relatively small amount of coolant from the periphery of a band presser wheel onto the continuous metal band at the point where the molten metal first contacts said band, with the unexpected beneficial effects of increasing the cast bar temperature and greatly reducing the amount of inverse segregation on the band-side surface of the resulting cast bar.

Abstract: A resulfurized ferrous alloy including lead characterized in that the lead is well dispersed in the steel matrix and the free lead globules are controlled as to size, is produced by introducing the lead into a steel melt in the form of a fine lead sulfide (PbS), or galena powder. The alloy produced exhibits improved machinability, which characteristic is further enhanced by the formation of manganese sulfide particles which are well distributed and have minimum aspect ratio (i.e., are round) when the melt has been deoxidized with manganese.
