HOT ROLLING PRACTICE – An Attempted Recollection

 · Fichier PDF

Hot rolling permits large deformations of the metal to be achieved with a small number of rolling cycles. Heating of Cold Stock One of the prequisites of the hot rolling practice is heating the input bloom/billet/slab from the room temperature to the rollable temperature. At that higher temperature the steel is transformed in to a
