IPC:

Metal rolling methods or mills for making semi-finished products of solid or profiled cross-section; Sequence of operations in milling trains; Layout of rolling-mill plant, e.g. grouping of stands; Succession of passes or of sectional pass alternations > for rolling wire or material of like small cross-section > in a non-continuous process

CPC:
