Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of temperature measurement, and in particular relates to a high-speed online temperature measurement device for an aluminum cold rolling mill. Background Art
[0002] The final rolling temperature of high-speed cold-rolled aluminum and aluminum alloy strips has a great influence on the final performance of aluminum strips. A higher cold rolling outlet temperature can improve the texture of aluminum alloys (such as 3104 canning materials), reduce the earing rate, and increase the yield rate of downstream manufacturers. Therefore, controlling the cold rolling outlet temperature of aluminum alloy strips has become a key point in process control. The traditional measurement method has always used offline manual contact thermocouple thermometers. Since the surface temperature of the aluminum coil is high after rolling (120-150℃), the inspector uses a contact thermometer to measure the side of the aluminum coil, resulting in discontinuous measurement points and large measurement errors. It cannot provide an accurate temperature value for judging the final rolling temperature of the aluminum coil, and thus cannot maintain a stable rolling process, which ultimately affects product performance and quality.

[0038] In this embodiment, by providing the support assembly 1 and the temperature measurement assembly 2, the U-shaped frame 11 is arranged on the outlet side of the high-speed cold rolling mill. By activating the cylinder 21, the cylinder 21 drives the thermometer 23 to lift to a suitable position. By activating the thermometer 23, continuous temperature measurement can be performed on the side surface of the aluminum coil on the outlet side of the high-speed cold rolling mill.
