摘要：The invention relates to a method for producing strips of non-alloy and low-alloy steel with homogeneous structures and properties by continuous hot-rolling, bypassing several times in the austenite zone and then in the ferrite zone, as well as byreeling. The invention is characterized in that the steel strip that was continuously castand/or rough rolled in the austenite zone is rolled by passing twice or more in theaustenite zone, at a starting temperature T>/=Ar3 +30 DEG C with a total strain ofeh>/=30 %. After each pass, the rolled product is intensively cooled until completion ofthe ferrite conversion. The rolled product is then subjected to final rolling by passingseveral times through the ferrite zone, with a total strain of en>/=60 %, until a finalthickness is obtained.
