METHOD OF MANUFACTURING AUSTENITIC STAINLESS STEEL STRIP

摘要

<P>PROBLEM TO BE SOLVED: To manufacture an austenitic stainless steel strip at high yield by rolling the entire length at high efficiency by suppressing the generation of work hardening in the unsteady area where a rolling speed is less than 50 m/min when manufacturing the austenitic stain steel strip by performing a plurality of passes of warm reverse rolling with a reversible rolling mill after beforehand heating a material to be rolled. Ž<P>SOLUTION: The temperature of the material 2 to be rolled during rolling does not lower to less than 50°C by adjusting in at least one pass of a plurality of passes in the existing region of a coolant on the surface of the material 2 to be rolled during rolling in an unsteady area is performed with a tandem six-stage rolling mill 4 so that the coolant which flows by covering the whole surface in the width direction of the material to be rolled is not existed on the outlet side of the tandem six-stage rolling mill 4 and also the coolant is existed in only the range from a position where the material 2 to be rolled is brought into contact with work rolls 5a, 5b to a position where is within 500 mm in the opposite direction of the rolling direction on the inlet side.
