Abstract
An improved method for heat-treatment of a strip in a continuous annealing installation in which the strip is heated or cooled by bringing it into contact with a heating or cooling roll having a thermal medium passed there-through. The improvements exist in that on the basis of much experimental data and mathematical analysis, a favorable range for selecting an outer diameter of a heating/cooling roll is determined as a function of various operation parameters.
