  • Rolling of hot strip and strip defectsIspatGuru

    Jan 14 2017 · For rolling of hot strip the slabs are heated initially at 1100 deg C to 1300 deg C. The temperature in the last finishing stand of the hot strip mill varies from 700 deg C to 900 deg C. It is always to be above the upper critical temperature to produce uniform equiaxed ferrite grains.

  • Roll wear prediction model for finishing stands of hot

    Jul 18 2013 · Roll wear in a hot strip mill (HSM) is a detrimental process which progressively worsens the rolls. This necessitates replacement of the rolls after rolling a number of strips. Roll wear adversely affects the strip shape and the performance of a mill. It is important therefore to quantify roll wear during the rolling process.
