Wire and Rod

High production speeds of 100-120 meters per second and cross motion of the wire result in high demands on the dynamics of the measurement technology. The contour measuring system must compensate for the effects of movements in order to achieve usable results. Only high speed measurements allow reactions to control and optimize the production.

TBK measurement systems have, for the first time, implemented a closed loop between contour measurement and the rolling mill control system. The presentation of specific key characteristics allows immediate corrective intervention in roll adjustment during production. As a pioneer in high speed measurement, which in this particular market segment is a crucial quality criterion for measurement systems, we work with highest image acquisition rates. Short exposure times minimize the influences from the cross motion of the wire.

Specific expertise

  • High clock rate (up to 2 million measurements per second)
  • Short exposure time and absolute synchronization of the measurement heads
  • Measuring equipment in the immediate vicinity of the rolling stands
  • Direct transmission of measured values to the control unit of the rolling stands
    (Closed loop control)
  • Measuring systems are used with two and three roll stands
  • Benefits in time and cost through direct control of production

  • High clock rate (up to 2 million measurements per second)
  • The basis for implementing a closed loop control
  • For the first time the measurement equipment assists to realize even the tightest production tolerances (up to 1/8 DIN)
