Abstract

The invention discloses a system for detecting a surface friction coefficient of a cold-rolled sheet on line. The system comprises hydraulic cylinders, a friction coefficient detecting device and a process control system, wherein the hydraulic cylinders are connected with an oil inlet tube, an oil outlet tube, and a pressure and displacement sensor; the oil inlet tube and the oil outlet tube are separately equipped with an electromagnetic regulating valve and a switching valve; the surface friction coefficient detecting device comprises working rollers, a supporting roller, bearing bases, a direct-current power generator and a current meter, wherein the working rollers are mounted in the two bearing bases; the bearing bases are separately connected with piston rods of the two hydraulic cylinders; one end of each working roller is connected with the direct-current power generator; the current meter is mounted on the direct-current power generator; and the process control system comprises a computer, an electromagnetic regulating valve PLC and an electromagnetic switching valve PLC which are connected with the computer for controlling pistons of the hydraulic cylinders to act, and an information feedback PLC which is connected with the computer for feeding back pressure information, piston displacement information and current meter current information in the hydraulic cylinders. The system realizes quick and accurate detecting for the surface friction coefficient of the cold-rolled sheet on line.

Description

technical field [0001] The invention relates to a system for on-line detection of the surface friction coefficient of a cold-rolled sheet and an application method thereof, belonging to the technical field of hot-dip galvanizing production. Background technique [0002] Usually, after the cold-rolled steel strip is processed by pickling, cold rolling, continuous annealing and other processes, the surface of the steel strip will be treated by hot-dip galvanizing process according to the final requirements of the user for the product. In the actual operation of the hot-dip galvanizing process, the key factor to ensure that the thickness of the zinc layer on the surface of the cold-rolled sheet and the product quality can meet the requirements of the user is to reasonably control the pressure of the gas ejected from the air knife equipment (hereinafter referred to as: air knife) to be able to To meet the requirements of the production process, and in the production process, the...
