Abstract
1,127,831. Continuous hot dipping process. NATIONAL STEEL CORP. June 14, 1965, No.25065/65. Heading C7F In a continuous hot dip process for coating strip such as steel with a metal such as Zn, the weight of the applied coating metal is controlled by passing the strip through a control zone above is applied across the full width of each of the the surface of the molten coating bath in which a stream of hot gas such as super-heated steam strip faces to impinge substantially perpendicularly i.e. 5 degrees above or below the perpendicular, the amount of gas impinging on the strip being controlled to obtain the required uniform coating weight. As shown in Fig.1 the strip 18 after passing through cleaning and/or annealing apparatus 12 passes via controlled atmosphere chute 14 into the molten bath 16. The strip passes through a controlled temperature zone 20 at the exit zone of the bath, the temperature being controlled by tubes 21 at 800‹ - 860‹F. The nozzles 24, 26 supplying the hot gas at 500‹ - 1500‹F. are supported in such a way that the angle of impingement of the gas, the height above the bath, the gap between the nozzles and the gap between the nozzles and the strip can all be adjusted. The temperature of the gas supplied is continuously measured and controlled and the coating weight of metal on the strip is also continuously measured and is controlled by either varying the rate of gas flow to the nozzles or by adjusting the distance of the nozzles from the strip. Different coating weights can be applied to each side of the strip by adjusting the above variables.
