  • A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

    As regards “abnormal” rolling conditions - which are more or less very “normal” for rolling mills - roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll failure have to be discussed and determined (or vice versa) to reduce the risk of repeated roll damage and its consequences, or indeed to eliminate the risk completely. These,

  • NEXT-GENERATION ROLLING MILL STAND | Primetals

    HSS is normally rolled in tandem cold mills (TCMs) that employ 4-high or 6-high rolling stands with work-roll diameters ranging from 630 mm to 420 mm. HSS exceeding 980 MPa has been manufactured by extending TCMs with the installation of an additional mill stand. However, the demand for steels with up to 1,500 MPa makes it almost impossible to produce advanced high-strength steels (AHSS,
