Abstract

A semi-ferritic stainless steel strip mfg. process involves continuously casting the molten steel between a pair of cooled rolls (2) and subjecting the withdrawn strip (3) below the rolls, to a quench medium to effect rapid cooling for a sufficient time to avoid austenite formation. - Appts. for the process is also claimed. - The strip (3) is pref. cooled at 300-500 deg.C/sec. just after leaving the roll gap. The quench medium may be (a) a molten bath (6) of one or more of Pb, Sn and Zn or a molten salt such as a mixt. of KNO3, NaNO2 and NaNO3, in which the bottom of the rolls (2) and the top portion of the strip (3) are immersed; or (b) a liquefied inert gas which is sprayed onto the faces of the upper portion of the strip below the rolls.
