Profile curves design of tooth-shape rolls

As for I-shaped profile steel, the flat web is replaced with corrugated web that makes the profile steel have predominant mechanical properties. The key technique of the hot rolling of I-shaped profile steel with wholly corrugated web is the profile design for the tooth-shape rolls of universal finishing stand. Being based on the condition of stabilized rolling and the relationship between corrugated web’s shape and the profile curve of rolls, in this paper, the profile curves of tooth-shape rolls are designed. The model of the rolls is constructed according to the curves’ equations. The rolling product can prove that the curves’ equations are correct.
