Abstract: A device for detecting the flatness of a sheet material includes a conveyor, a gantry, a beam, an industrial camera unit, a speed measurement unit, a vibration measurement unit, a multi-line laser, a cable carrier, an industrial controller, and a control cabinet. The conveyor is disposed beneath the gantry and includes a plurality of pinch roll assemblies for feeding a sheet material. The beam is disposed on the gantry and includes a first side and a second side. The industrial camera unit is disposed on the first side of the beam and includes at least two industrial cameras. The speed measurement unit is disposed between the at least two industrial cameras. The vibration measurement unit is disposed on the second side of the beam and includes at least two distance measurement devices. The multi-line laser is disposed between the at least two distance measurement devices.

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.
