Abstract

This invention relates to a method of hot rolling a fragile strip, and equipment for practicing the method. During a hot rolling operation according to this method, both side portions of a roll body including the portions of the same which are in the vicinity of the strip edge-contacting portions thereof are heated so as to control the heat crown of the roll. The rolling equipment has a heating unit capable of varying a heating range in the lengthwise direction of a rolling roll, and a plurality of temperature sensors arranged in the lengthwise direction of the roll, and is capable of controlling the heating range of the heating unit according to temperature information from the temperature sensors.
