  • Cold Rolling | Nippon Yakin

    Cold Rolling In the cold rolling process, a hot-rolled coil is made thinner by passing it between two rolls at room temperature. Not only is the thickness of the material made uniform, but the internal structure is made homogeneous at a microscopic level, and the surface of the roll is transferred to the material to provide a polished finish.

  • Cold Rolling - an overview | ScienceDirect Topics

    This mill is used to cold-roll brass and copper into thin sheets. It is not possible to use flying micrometers for thickness measurement of this material because of the high degree of surface finish which is required and the malleable nature of the material. The mill produces brass strip up to 40 cm width and 0.1 mm thickness at rolling speeds approaching 200 m/min. The thickness of brass on the

  • Efficient Special Steel Mills from Primetals

    The 12Hi cold roll (CR) mill was developed independently by Primetals Technologies to roll stainless steel, copper alloys, and nickel alloys. Compared with a ZR mill, the number of rolls is less and it provides greater shape control. In addition, the work roll diameter range is significantly broader, allowing high accuracy rolling of a greater range of materials, soft, medium, and hard.

  • NEXT-GENERATION ROLLING MILL STAND |

    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) simply by increasing the number of stands. Smaller-diameter work rolls that reduce the rolling

    The cold rolling mill is used to pass hot-rolled coils produced from the hot rolling mill between two rotating rolls and produce products of the desired thickness. The cold rolling process provides a more refined surface, improved mechanical properties and excellent thickness product precision. Cold rolling mills are largely divided into the TCM (Tandem Cold Rolling Mill) and the RCM (Reversing Cold Rolling Mill). In the TCM, material passes 5 or 6 rolling mills
