Title:
CONTINUOUS ANNEALING EQUIPMENT, CONTINUOUS ANNEALING METHOD, COLD-ROLLED STEEL SHEET MANUFACTURING METHOD, AND PLATED STEEL SHEET MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/209364
Kind Code:
A1
Abstract:
Provided are continuous annealing equipment capable of swiftly responding to a fluctuation in material characteristics and minimizing a fluctuation in mechanical characteristics of a product, and a corresponding continuous annealing method, cold-rolled steel sheet manufacturing method, and plated steel sheet manufacturing method. This continuous annealing equipment is a steel sheet continuous annealing equipment having a heating zone (6) and a soaking zone (7) in said order, wherein the soaking zone (7): includes a first soaking zone (7A) and a second soaking zone (7B) disposed subsequent to the first soaking zone (7A); and is provided with a first induction heating device (9) which is disposed between the first soaking zone (7A) and the second soaking zone (7B) and a measurement device (10) which is disposed at the exit of the second soaking zone (7B) and measures an austenite fraction of the steel sheet.
