B21B1/08 - CPC Classification

Classification description:

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 structural sections, i.e. work of special cross-section, e.g. angle steel

Sub-classes:

B21B1/0805 » {Flat bars, i.e. having a substantially rectangular cross-section} 12
B21B1/0815 » {from flat-rolled products, e.g. by longitudinal shearing} 4
B21B1/082 » Piling sections having lateral edges specially adapted for interlocking with each other in order to build a wall 9
B21B1/085 » Rail sections 32
B21B1/088 » H- or I-sections 27
B21B1/09 » L-sections 7
B21B1/092 » T-sections 4
B21B1/095 » U-or channel sections 15
B21B1/098 » Z-sections 4
B21B1/10 » in a single two-high or universal rolling mill {stand } 0
B21B1/12 » in a continuous process, {i.e. without reversing stands } 6
B21B1/14 » in a non-continuous process, {i.e. at least one reversing stand } 5
B21B2001/081 » {Roughening or texturing surfaces of structural sections, bars, rounds, wire rods} 6
