flow chart of plc used in rolling mill

  • Design and PLC Implementation of Complex Industrial

    A steel rolling mill produces a sheet of uniform thickness from a slab of steel. It typically consists of several rolling stages with rollers in each stage compressing the sheet of steel passing through it (Figure 1). In between the roller stages looper stages maintain the tension in the sheet and prevent tearing and formation of slack.

    Rod mills have the highest rolling speeds with interpass times in the finishing stand of 15–150 ms. This is too short for either static recrystallization or strain-induced precipitation and dynamic recrystallization is the main grain refining mechanism. Microalloying could limit grain growth during rolling by particle pinning and solute drag.
