Packaging steel strip thickness gauge using method of introduction

Packaging steel strip thickness gauge using method of profile thickness gauge has two kinds of contact type and non-contact, contact thickness meter long measurement cycle and low measurement precision, wide measurement range, is used in low speed, under the condition of cold rolling workpiece thickness measurement. Non-contact thickness gauge with reaction speed, high accuracy of measurement, which can realize the continuous, extremely easy to computer networking and realize the automatic gauge control, non-contact thickness gauge is widely used. Non-contact thickness gauge with X-ray thickness gauge, & gamma; X-ray thickness gauge ( Main americium and cesium) , ultrasonic, infrared and laser thickness gauge, before two kinds of radiation thickness gauge, they are based on certain energy rays through the steel plate, the intensity of radiation attenuation and the thickness of the steel plate has a certain relationship, the principle of the ray made by gamma ray source, generally after plate to absorb part of the bottom-up remaining accepted by detector. When measured space without steel plate, using the known thickness of base plate correction. Modern thickness gauge is a set of computer data testing and processing system, with functions of operation ( Such as according to the target thickness and the thickness of the measured input, calculate and output the measured thickness deviation) , since the correction, self diagnosis and maintenance of intelligent functions. γ Ray than X-ray penetration ability is strong, but compared with X-ray is difficult to realize high radiation dose. Large doses can achieve low noise and high response speed. X-ray thickness gauge is suitable for thin plate and high-speed production lines such as the plate thickness measurement, can be installed in the mill finishing mill group of hot rolling steel strip, cold rolled steel strip milk machine export and rack. Americium & gamma; X-ray thickness gauge is mainly used for measuring the thickness of low speed production line, sheet because of isotope americium & gamma radiation; Ray energy than isotope cesium & gamma radiation; Ray energy is low, cover is easy, can be used for cold rolling line of small thickness gauge. Cesium & gamma; X-ray thickness gauge can be installed in the hot strip roughing mill group, heat plate finishing mill for export and the finishing line.
