A method of forming tailored cast blanks, the method comprising:
- determining a thickness pattern and profile pattern for a tailored cast blank;
- generating a layout for a series of tailored cast blanks having the determined thickness and profile patterns;
- casting a strip in accordance with the layout of the tailored cast blanks, including the steps of:
- varying a width of the strip between lateral edges of the strip during the casting of the strip;
- and
- during the casting in a caster including rolls at opposite surfaces of the strip, varying a caster roll gap between the rolls at opposite surfaces of the strip by moving the rolls in a direction perpendicular to a direction of the strip and then rolling the strip to modify respective thicknesses of sections of tailored cast blanks which are formed from the strip being rolled;
- and
- forming the tailored cast blanks from the strip,
- wherein the varying of the width of the strip is performed without moving the rolls and a width of the tailored cast blanks varies along at least a part of the length of at least one of the tailored cast blanks.
