# A process with a chain of subprocesses: the hot rolling of ingot I-2026-0417 decomposes into heating, one rolling pass
# and cooling (proper occurrent parts that start and end it and follow each other), takes the ingot as specified input,
# gives a strand as specified output and realizes a plan that concretizes the rolling schedule. Invented identifiers.
