Patent ID: 8163348

Claim:
A method for the hot-dip coating of a hot-rolled steel strip EN 10111-DD11 to DD14 to increase its tensile strength, whereby the steel strip passes through a pickling station, a rinsing station, a drying station, a heating furnace and then a melting bath wherein the final thickness and the thickness tolerance of the hot-dip coated hot-rolled steel strip EN 10111-DD11 are achieved, after the hot-dip coated, hot-rolled steel strip EN 10111-DD11 to DD14 has cooled down to 25° C. to 55° C., by a controlled thickness reduction in a rolling-mill stand in the processing line, whereby at least one thickness gauge located in the exit of the rolling-mill stand checks whether the final thickness has been achieved and any deviations upwards or downwards are fed back as a control signal for the adjustment of the rolling-mill stand so that the thickness reduction can be correspondingly increased or decreased so that the controlled thickness reduction in the hot-dip coated, hot-rolled steel strip lies in a range of 6.5% to 10% and with such a thickness reduction, the hot-dip coated, hot-rolled steel strip EN 10111-DD11 to DD14 has a thickness tolerance relative to the center of the strip of +0.01 mm or better.
