Ultrasonic deviation rectification detection device with surface material and cooling sleeve of heat-proof lining structure

Abstract

The invention provides an ultrasonic deviation rectification detection device with a surface material and a cooling sleeve of a heat-proof lining structure. The ultrasonic deviation rectification detection device with the surface material and the cooling sleeve of the heat-proof lining structure have ultrasonic waves generated by an ultrasonic generator transmit the ultrasonic waves towards the length direction of the strip steel detection passing through a transmitting antenna, and the ultrasonic detection receiving end detects reflected the ultrasonic waves; after a signal processing circuitreceives the information of the ultrasonic waves, the actual amount of the left ultrasonic reflection value and the right ultrasonic reflection value are calculated, the actual values of the two sides are calculated and compared with the reference value, the difference is obtained, the deviation is calculated, a deviation rectification signal is sent to a deviation rectification driving device, and a driving device deflects a deviation rectification roller. The cooling sleeve is provided with two working cavities, the heat-proof lining structure is provided with a high-temperature-resistant protective plate, an outer side metal plate, a high-molecular insulating material and an inner side metal plate. The ultrasonic deviation rectification detection device has the advantages that the collection of integrated transmit and receive antennas is adopted, the cooling sleeve is thermally insulated, and the large amplitude of heat insulation reduces the flow usage of the cooling gas source.

Description

technical field [0001] The invention belongs to the technical field of steel product production lines, and relates to a strip steel deviation correction and detection device for cold rolling production lines. Background technique [0002] The steel plate produced in the continuous production line is in the shape of a strip, referred to as "strip steel". In the production process, the final product can only be realized through multiple processes and equipment. The strip steel is generally changed in direction and tension achieved by rotating rollers. , in the high-speed production line, the friction force of the contact surface between the strip steel and the roller will affect the accuracy of the strip steel movement. In actual application, due to the performance and process requirements of the production product, the roughness and friction force of the roller and strip steel cannot be infinitely enlarged. Reduced, the strip is easy to run off. [0003] On the high-speed co...

Problems solved by technology

[0004] In the traditional way, it is mainly through the use of optical detection devices, capacitive detection devices, microwave detection devices, etc. Thanks to the detection devices in harsh environments, they are easily affected by water vapor, water, dust, toxic and harmful gases, high temperatures, etc. in the environment. In the process of use, the detection accuracy is unstable with the shortening of the deterioration period, which may easily cause wrong detection and cause the signal output to exceed the range, directly drive the deviation correction equipment to run in the opposite direction, and seriously cause the outage roller to stop or break the belt accident. It is not conducive to the smooth flow of production, the processing cost remains high, the speed of the production line cannot be increased normally, and the functional accuracy of the equipment cannot meet the production needs

[0005] When these detection devices are used in the annealing furnace, the high temperature and toxic and harmful gases have higher requirements for the detection device, and the body of the detection device cannot be effectively cooled, the high temperature resistance performance is reduced, the failure rate is increased, and the strip steel is easily damaged in the furnace. Deviation, production line slowdown, thermal wrinkles, etc., more seriously restrict production

It generally takes 12-48 hours for the recovery of the broken belt of the annealing furnace, which is more dangerous during the treatment process, especially the risk factor of the vertical annealing furnace increases
