Abstract (en)
[origin: WO9700975A1] Cold rolled steel plate is continuously annealed by means of a continuous annealing equipment which comprises heating means provided in a heating zone and a soaking zone to make use of Joule heat, and cooling means provided in a cooling zone to make use of gas-liquid. Further, provided is a heating device which rapidly provides auxiliary temperature-rise at any portion of the soaking zone in a short period of time to perform heating control so as to set a value of annealing parameter (AP) to -33 or more whereby workability and BH property are improved to continuously anneal steel plates in a compact manner by rapid heating and cooling which are favorably controlled.
