SYSTEM AND A METHOD FOR MEASURING SURFACE ROUGHNESS, CAPABLE OF OBTAINING A SURFACE ROUGHNESS MEASUREMENT VALUE ACCORDING TO DISTANCES OF FRONT AND REAR SIDES OF A COIL
PURPOSE: A system and a method for measuring surface roughness are provided to detect a welding unit informing a start of a continuous coil and to calculate a cut distance when the coil is cut into a plurality of sub-product coils before shipment.;CONSTITUTION: A system for measuring surface roughness comprises devices for measuring surface roughness of front and rear surfaces, and a welding unit detector(10), and a tracking device. The devices for measuring surface roughness of front and rear surfaces installed to be spaced from each other measure surface roughness of front and rear surfaces of a plated steel sheet. The welding unit detector detects a welding unit of a coil continuously welded and transmits signals for detecting the welding unit. The tracking device detects a start position of the welding unit at a moment when the welding unit reaches to the devices for measuring surface roughness.;COPYRIGHT KIPO 2012
