摘要
If the flat web of I-shaped profile steel is replaced by corrugated web, the profile steel will have predominant mechanical properties. The crucial technique for the hot rolling of I-shaped profile steel with wholly corrugated web is the profile design for the tooth-shaped rolls of universal finishing stand. Based on the condition of stabilized rolling and the relationship between corrugated web's shape and the profile curve of rolls, the profile curves of tooth-shaped rolls are designed. The model of the rolls is set up according to the curves' equations. The rolling product proves that the curves' equations are correct.
