Abstract

PURPOSE:To reduce rolling cost, an existing univeraal line is converted to a rolling method using universal mill and edger mill instead of caliber attached mill. CONSTITUTION:In the conventional manner, breakdown mill is used to provide a steel material of cross section shape 1 to be used in this process. The crude rolled strip of steel 1 is reciprocally passed through the universal mill 5 to be rolled, which is then subjected to the edger mill 6 rolling. The finishing rolling mill 7 performs finishing to provide a wide flat bar product 1' having a desired thickness and width. In some case, the finishing roll may be performed by the mill attached with finishing caliber.
