Whether the width and thickness of the flat steel/ribbon iron width measurement device can meet the standard in the production process directly determines the quality of the flat steel/ribbon iron. How to carry out high-precision measurement of flat steel produced at high speed is the key technology to improve the production efficiency and quality of flat steel.

The flat steel/ribbon iron high-speed width measuring system developed by our company can monitor the whole process of flat steel production in real time. It can be used for the on-line analysis, processing, display and function alarm for the detected parameters of the width and thickness. We can provide customers with professional solutions.

The measuring principle of the system
The device adopts industrial laser sensor, through the principle of laser triangulation reflection: the laser beam is amplified to form a laser line and projected onto the surface of the object to be measured, the reflected light passes through the high-quality optical system to be projected onto the imaging matrix.

Then the distance (Z axis) from the sensor to the measured surface and position information (X axis) along the laser line can be got after calculating. By moving the measured object or sensor, a set of three-dimensional measured value can be obtained. When measuring, we need to install a laser measurement sensor device directly above and below the ribbon iron.

When the ribbon iron passes through, the width distance from the left and right of the ribbon iron and the height distance from the sensor to the ribbon iron can be measured by laser scanning. The thickness of flat steel can be measured by two sensors up and down.

The flat steel width measuring system is mainly composed of line laser measurement sensors, connectors, front-end data acquisition, operation station (workstation) and server, mechanical structure, cooling protection device, etc.

These devices form an independent measurement and calculation network, and through the high-speed data measurement and calculation of the system to achieve the alarm control of the detection record.
