A steel plate quality assurance system according to a steel plate manufacturing line, and facilities thereof are provided. Specifically, the present invention provides a steel plate quality assurance system and facilities thereof, wherein the steel plate quality assurance system measures, with a steel plate manufacturing line including a finishing mill of a steel plate manufacturing line, and accelerated cooling equipment disposed on the downstream side of the finishing mill in the advancing direction of the steel plate manufacturing line, temperature of at least the whole area of the upper surface of a steel plate, or the whole area of the lower surface of a steel plate of a steel plate to perform quality assurance, and includes temperature measurement means; temperature analysis means; and mechanical property determining means; with the temperature measurement means including a thermometer disposed on at least the upstream side or downstream side of the finishing mill, or/and at least the upstream side or downstream side of the accelerated cooling equipment, and temperature collecting means configured to collect temperature measured at the thermometer; with the temperature analysis means creating a temperature MAP of the whole area of a steel plate from the temperature collected at the temperature collecting means; and with the mechanical property determining means estimating the material property of the whole area of s steel plate from the temperature MAP to perform judgment of acceptance. |
