Embodiment Construction

[0036] The present invention will be further elaborated below in conjunction with accompanying drawing:

[0037] Such as figure 1 As shown, the hot-rolled strip temperature and flatness synchronous detection device of the present invention mainly includes a flatness detection device 2, a temperature measurement device 4, a cooling device 6 and a signal processing module. The measuring roller 10 of the plate shape detection device is in direct contact with the surface of the plate strip 3 to be tested, and accurate plate shape signals are obtained through the measuring probe 28 and the pressure sensor.

[0038] The temperature measurement device 4 uses an infrared thermal imager 46 to collect the lateral temperature distribution of the online strip, and obtain the temperature field information of the strip. The signal processing module receives the shape signal and temperature information, and realizes the temperature error compensation of the shape through data conversion and...

Abstract

The invention discloses a synchronous on-line hot rolled strip temperature and shape detection device which comprises a strip shape detection device, a temperature measuring device, a signal processing module and a cooling device, wherein the strip shape detection device is used for enabling a measuring roller to directly contact the surface of a strip to be tested and used for acquiring strip shape signals through a measuring probe and a pressure sensor; the temperature measuring device is used for acquiring on-line strip transverse temperature distribution rules by using an infrared thermalimaging instrument to obtain temperature field information of a strip; the signal processing module is used for receiving strip shape signals and temperature information and used for carrying out dataconversion and processing; the cooling device is used for receiving feedback loops of the signal processing module to control current reduction of a switch of a one-way valve. The device is simple and reasonable in structure and easy to mount and maintain, synchronous on-line detection of the temperature and the shape of a hot rolled strip can be achieved, the precision of strip shape detection can be improved through temperature error compensation, and great significances can be achieved for practical production.

Description

technical field [0001] The invention belongs to the technical field of rolling measurement, and relates to a synchronous on-line detection device for the temperature and shape of a hot-rolled strip. Background technique [0002] As an important industrial material, hot-rolled strip products are widely used in automobile manufacturing, construction facilities, aerospace and household appliances, etc., and have a good application prospect. As an important index to measure the quality of hot-rolled strip products, the shape of the plate has attracted more and more attention from enterprises and researchers in related fields. The quality of the shape will directly affect the stability of the rolling process and ultimately determine the production of the strip. Whether it can be carried out smoothly and whether the product specifications meet the market demand. In the strip rolling process, it is necessary to accurately detect and control the shape of the strip in order to produ...
