Descaling of Medium C and High Si, Mn Steels
Descaling of slabs exiting reheat furnaces prior to hot rolling is an important step to improve surface quality in the steelmaking process. An induction heating system with a controlled atmosphere that replicates the combustion atmosphere in a commercial slab reheat furnace was used to oxidize high-Si, Mn and medium-C steels. High-pressure water jet descaling was performed following scale formation using a laboratory setup that mimicked the industrial descaling process. Effects of nozzle impact factor (N/mm2) on scale removability for the different steels were investigated. The critical values of impact factor required for scale removal are discussed.
