Method for hot rolling a metal slab, strip or sheet
Abstract:
A method for hot rolling a metal strip or metal sheet, wherein 1.a) the slab or the strip or sheet is subjected in a first step to one or more reshaping actions in a hot rolling mill for producing a uniform, fine, recrystallised austenite structure and 2) the slab or the strip or sheet is then subjected in a second step to cooling for producing a fine-grain structure. The slab or the strip or sheet is subjected to heating between at least two roll stands of the hot rolling mill during performance of the step 1.a). The roll stands are arranged to follow one another in a rolling direction and in each of which the slab or the strip or sheet is subjected to reshaping. A heater for heating the rolling stock is arranged between at least two of the roll stands.
