摘要： The invention relates to a method of and a plant for making hot-rolled strips of cast metal, wherein the cast strip is subjected as a rough strip to at least a first step for momogenizing the grain structure in a protective gas and the cast strip is then subjected to at least a further heat-treatment step before it is rolled to reduce its thickness. After the thickness reduction the cast strip is subjected to a second step of homogenization or recrystallization of its grain structure before finally the strip is passed to a cutter and a finished rolled hot piece is severed from the following strip.
