Hot-rolled to prevent sliver defects in austenitic stainless steel hot rolled steel

摘要

In the present invention, the austenitic stainless steel continuous casting slab is machined so that the grinding surface is 50-150μm with a continuous wheel on the upper and lower surfaces up to the width specified by the following formula without exceeding 220mm from both edges. The slab is heated in the vertical scale breaking device just before rough rolling, width-rolled and then sprayed with high-pressure water to remove the scale, and the method of manufacturing hot rolled steel sheet subjected to rough rolling and finishing rolling.;Slab edge grinding width (mm) = 8 × width rolling amount (mm) + (110 ± 15);(Width rolling width (mm) = slab width (mm) x 1.025-vertical roll spacing (mm))
