Abstract

PURPOSE: To keep annealed form in good condition and to increase the speed of cooling by cooling the metallic band transferred in the continuous heat treatment line in an aqueous solution in a specified area.
CONSTITUTION: The metallic band in a continuous heat treatment line is cooled in an area shown by the inequality I where (l); width of metallic plate, L; length of sink roll, and α; amount of crown of sink roll. Especially, in case of thin material the center of an area corresponding to the end of steel band of the sink roll is sometimes made hollow and steam is passed to heat the surface of the roll, or cooling water is passed to accelerate cooling.
