Accurate dimensional measurement of strip and plate during hot rolling is essential for producing high-quality steel and achieving maximum output. A series of measurement systems have been developed using high-resolution and high-speed digital cameras to address the harsh usage environment in the metal industry.
Stereoscopic angle width measuring instrument
The design and installation of a stereoscopic width measurement system above the roller conveyor of hot-rolled strip steel and hot-rolled plate is a new technology for measuring the width of strip/plate products. For applications at the exit of roughing mills or finishing mills, the self thermal radiation of the red hot strip/plate provides sufficient contrast for width measurement. For other applications where the temperature of the strip/sheet is below 600 ° C, we can provide a rear or front light source.
The principle of stereoscopic angle measurement overcomes the inherent difficulties in width measurement of hot-rolled strip/plate, such as uneven thickness, inclination, warping, and jumping of the strip.
Cutting optimization system
The cutting optimization system captures the head and tail images of the intermediate billet. By analyzing the image, the target contour is calculated, and the optimal cutting length is determined based on the shape of the target’s head and tail and the cutting strategy. These cutting points can be adjusted by the operator and transmitted to the cutting controller. It can significantly reduce shear losses.

install
The width gauge is only equipped with one electrical connector (power input and data input/output interface), one Ethernet interface, and three quick interfaces (cooling water inlet and outlet, compressed air interface), making installation quick and convenient.
The width gauge or shear optimization system is equipped with internal and remote analog/digital input/output interfaces, Ethernet TCP/IP interfaces, Profibus DP interfaces, and serial connections, making it easy to connect with any automation system and host.
structure
The width gauge is based on a client server architecture and can be directly connected to Ethernet. Various width gauges (servers) online provide measurement data, while different clients (control room operator clients, maintenance and diagnostic personnel clients, and quality department clients, etc.) can obtain the required data separately for display, recording, or storage.
