Abstract: A method for heating a blank in a first heating furnace and a second heating furnace. The first heating furnace includes a first chamber and a second chamber communicating with the first chamber. The method includes: 1) heating the blank in the first chamber to the temperature of less than 300° C.; 2) transferring the blank heated in the first chamber to the second heating furnace, and heating the blank to the temperature of between 350° C. and 850° C., where the temperature of the second heating furnace is detected using a thermocouple, and the temperature of the blank is detected by an optical thermometer; 3) transferring the blank heated in the second heating furnace to the second chamber, and measuring the temperature of the blank using a contact thermometer; and 4) transferring the blank from 3) to a rolling mill.
