Abstract
1,154,422. Annealing steel sheet. RASSELSTEIN A.G. Aug. 19, 1966, No.37326/66. Headings C7A and C7N. Low carbon steel sheet is heated at not less than 500‹ C. per second to an annealing temperature within the range 780‹ C. -900‹ C., and after holding for not more than 5 seconds is quenched at an average cooling rate of not less than 250‹ C. per second to a temperature below 150‹ C. The sheet may pass continuously through apparatus in which it is heated by electron beam or by radiation, after which it is cooled by liquid spray or by passage over cooling rollers. The strip may then be flattened prior to rolling, or may be kept under tension during cooling.
