Technological investigation on the Short StrokeWidth Control Rolling in the Rougher Mills ofHot Strip Continuous Rolling Mill Train

According to technological requirement of hot charge rolling and hot direct rolhng, inthis paper, we investigated the technology of the width control rolling in the rougher mills of hotstrip continuous rolling mill train. On the basis of improving width range of continuous casting ofslab, we obtained a good result of greatly increasing the yield of slab→coil is achieved.
