Abstract

DC60 (27/06/44) Thin long steel strip (11) is made through the throttle pinion roller stand (12) containing the throttle clamping roller (13) to the presser (16) that consists of a pair of The working roller (17) and the upper and lower support rollers (18) the long bar (11) pass through the contact contact between the working roller (17) and the compression force. Working roller to reduce the thickness of the long strip. The throttle clamping roller (13) will feed the tension to the long bar passed through the working roller (17) in order to defect the The curl in the length is minimal. The tension fed by the pinch roller (13) is high enough to assure that no part of the long strip that passes through the working roller will Is in longitudinal compression Which exceeds the stress caused by the deflection of the long bar The feed tension is low enough to cause the strip elongation no more than 1% through the creep.The long strip may be heat rolled by a work roller (17) at temperatures in the range of 700 degrees.
