Abstract
The invention relates to a method for measuring steel coil radius of a strip steel reel coiler working line. The method comprises the following steps: coaxially mounting an incremental encoder with a steering roller in front of the coiler; connecting the signal output end of the incremental encoder with the signal input end of a counting module of a PLC; inputting a strip steel thickness parameter value h on the strip steel reel coiler working line into the PLC; when the head of the strip steel arrives at a measuring roller, starting the counting module, reading the number Md1 of pulses which are output from the incremental encoder; substituting the number Md1 of the pulses into a first formula L=Md1*(D*(pi)/n), thereby calculating the length L of the strip steel which passes through the steering roller; and substituting the length L of the strip steel into a second formula R1=[(h*L+(pi)*R0<2>)/pi]<1/2>, thereby calculating a real-time steel coil radius R1. The method of the invention has advantages of high speed, high precision, stable operation and accurate data.
