An apparatus in which a metal strip is passed in contact partly around the outer circumferences of a number of spaced cooling rolls through which coolant passes. The apparatus includes temperature detectors for detecting the temperature of the strip before contact with each of the cooling rolls, and coolant temperature regulators controlled in accordance with the detected temperature of the strip to adjust the temperature of the coolant passing through each cooling roll to a range which limits the temperature drop of the strip such that unacceptable irregularities or distortions in the configuration of the strip cannot occur. The coolant used for each cooling roll is selected with a boiling point appropriate to the respective detected temperature for each roll. In the preferred arrangement, further temperature detectors are provided for each cooling roll to detect the temperature of the coolant, and output signals from both detectors are inputted to a control for regulating a flow rate valve.
