Whemco Steel Casting Inc. Cast Back Up Rolls: Solidification Fast solidification against metal mould gives finer structures Excellent central soundness achieved by diluting core with a low alloy steel Combines best of static and duplex technology with DH hardening Up to 6 cast BU and 4 Section produced per week CAST BU ROLLS

Whemco Steel Casting Inc. Cast Back Up Rolls: Dilution Process Bridging and segregation would occur if solidification was not interrupted. A hot lower alloy steel dilution of the core is used to remove segregates The improved temperature distribution allows Progressive solidification to continue The final roll has an internal Soundness equivalent to Forged roll
