The straight hair coil shall be cut or rewound after fin- ishing line treatment such as head cutting, tail cutting, edge cutting and multi-pass straightening and leveling
Hot-rolled plate/coil is made by con- tinously rolling the slab, after heat- ing the slab in the reheating furnace, by the roughing mill and finishing mill, and it is coiled for a easier transportation.
Hot rolled plate has low hardness, easy processing, good ductility and good plasticity.
Hot rolled steel is mainly used in the production of steel structures, bridg- es, ships and vehicles. After heat treatment engineering, it is used for the production of various mechanical parts.
