METHOD FOR HEAT-TREATMENT OF A STRIP

摘要

A 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 therethrough is improved. The improvements exist in that on the basis of a lot of 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.
