WKM Software Module

The calculation of rolling forces and torques during the heavy plate rolling in the recovered state after the temperature delay at the 4-high reverse stand

Programový modul WKM

Software module creation procedure:

  • »performing and evaluation of interrupted plastometric tests with a goal to find out the flow stress of particular steels at different technological conditions including its time relation
  • »model function definition describing the steel recovery in relation on time and its coefficients determination on the basis of results of plastometric experiments with a help of regression analysis
  • »creating of WKM calculation model for the calculation of rolling forces and torques and its software realization
  • »software module implementation into the rolling mill (Level 2) control system
Heavy plate hot rolling

Calculated rolling forces and moments in individual passes

Heavy plate hot rolling

Flow stress curves of steel during particular passes before and after the temperature delay
