The table above shows the format of the cost model that estimates rebar conversion costs from carbon steel billet, on a traditional 14-20 stand semi-continuous rolling mill. Mill output is assumed to be rebar in lengths of 10-24mm diameter (not bar-in-coil).

This model is available for purchase from However, it should be understood that any further use of the model is likely to require

  • a knowledge of upstream cost structures [steelmaking, casting]
  • further adaptation for actual billet costs, for labour and energy costs, scrap prices, for depreciation charges etc
  • adjustment for local operational circumstances.
