PURPOSE:To obtain a high quality steel sheet/bar produce in a short time by installing driving rolls and nondriving rolls in a stand and pressing defects inside a rolled stock into welding by rolling the stock by the nondriving rolls in addition to rolling by the driving rolls. CONSTITUTION:As for a combination stand, both driving horizontal rolls H1 and nondriving vertical rolls V2 are installed in one housing and a rolled stock 1 is rolled in the direction shown by the arrow by applying compressive force to the stock 1 between the rolls H1 and V2. Thus, strength of compressive stresses between both driving and nondriving rolls is adjustable by changing drafting amounts in the nondriving rolls. A center-to-center distance between both the rolls is extremely shortened; a high quality steel sheet/bar product is manufactured. |
