Cutting machines

The Works has a pool of experience in design, manufacture and complete delivery of various types of metal ( billet, sheet and plate and bar) shears вeing one of the key shaping machines in the rolling-mill equipment production of Iron and Steel Plants.

Shears for cutting hot and cold rolled products either in the course of movement or during their stop are very critical and intricate machines with respect to kinematics and design that are included in the rolling mills and lines complex.

Technical characteristics of cutting machines and their designs often determine the mills and lines production as well as the composition and arrangement of the other machines incorporated in these lines.

NKMZ designs and delivers for CCMs, breakdown, billet, section, plate and wide-strip mills the following cutting machines:

  • shears for hot rolled products cutting;
  • guillotine dividing shears;
  • “rolling-cut” dividing shears;
  • “rolling-cut” slitting shears;
  • double-cut “rolling-cut” trimming shears;
  • rotary side trimming shears;
  • shears for cutting bars and structural shapers;
  • bar flying shears;
  • flying breaking shears;
  • drum-type flying shears;
  • hydraulic shears;
  • crop choppers.

The kinematic and power parameters of the shears are calculated by means of computers using the latest software that enables us within the shortest possible time to design the shears with optimum relation between the materials and power consumption during operation.
