ABSTRACT OF THE DISCLOSURE Hot formed rod is prepared in a rolling mill by removing oxide from the surface of a nascent cast bar while the bar is in a non-oxidizing environment. Oxide is removed from the surface of the bar by means such as wire brushing, for example, with the oxide removing means and the nascent bar being enclosed in a non-oxidizing or reducing environ- ment to improve the removal of existing oxide and to inhibit formation of new oxide on the bar while the bar travels from the oxide-removing means to the rolling mill to be hot- formed. Removal of oxide while the bar is in a non-oxidizing environment enhances the removal of oxide and lessens the unwanted removal of metal underlying the surface oxide.
