Hot Mill Reheat or Tunnel Furnace - Heating/Soaking Zone

In the hot mill, steel strands, billets, or slabs are heated in the reheat furnace so that they become soft enough to roll. If the metal is too cold, then it will be too hard, and it will crack and stress the rolling equipment. If the metal is too hot, then cracking, surface melting and blemishes will occur when rolled. If the metal is not.
