Abstract
Metal ingots are mold cast at a smelter with a solid, unmelted alloy or metallurgical additive body placed in the mold so that the molten metal in the ingot solidifies around the body. The metal and body in the ingot are melted at a foundry to freshly distribute the melted alloy or metallurgical additive material in the body throughout the remelted ingot metal immediately before casting useful articles from the melted ingot.
