Zusammenfassung:	PURPOSE:To obtain a hot dip plated steel strip by subjecting a descaled slab to finish rolling, cooling, coiling and surface cleaning in prescribed conditions and thereafter controlling its atmosphere into a nonoxidizing one till immediately before its plating. CONSTITUTION:At the time of a continuous hot rolling, descaling is executed before the start of finish rolling. Next, it is subjected to the finish rolling and is coild into the shape of a coil in the conditions satisfying the inequalities of 0.027XFT+0.00018X(FT+CT)Xt
