Abstract
Method of reducing the formation of folds on metal strips (1) exposed to rapid heating in continuous heat-treatment lines, in which lines said strips are caused to pass through heating sections (2) comprising successive and separate heating means (5; 5a; 5b; 5c; 5d), wherein the average slope of the increase in temperature of the strip between the inlet and the outlet of a heating means decreases from one heating means to the following heating means.
Claims10
A method for reducing thermally induced wrinkle formation on a metal strip (1) undergoing rapid heating in continuous heat-treatment lines, in which said strip passes through heating sections (2) comprising successive and distinct heating means (5, 5a, 5b, 5c, 5d), wherein the average gradient for temperature increase of the strip between entering and leaving a heating means falls from one heating means to the next heating means.
