Definitions

  • the insufficient flatness of the hot rolled steel strips caused defective appearance of coil which presented noticeable problems in the succeeding producing steps such as, for example in the case of mother material for cold rolling, decrease in pickling efficiency resulted from decrease in passability of plates in the pickling line and wandering of the strip.
  • the strip used in this test was a common hot-rolled steel strip of thickness of 1.2-3.2 mm and width of 900-1300 mm.
