Overview The width measuring system adopts dual industrial CCD cameras to proceed the online measurement of the steel plate on the roller bed by using the principle of stereo vision technology, and combines the high-speed digital signal processing technology and programming software to process the signals accordingly, and displays the relevant data and measurement curves, so that we can realize precise control of the steelmaking process during production. The system realizes the width measurement of the slab through the line scan cameras installed on both sides of the gantry slab, and the measurement data is transmitted to the host system through the optical fiber. Accurately calculate the actual width of the slab and the width deviation of the slab from the data collected by the linear array CCD camera with up to 8K pixels and the relative position of the double linear array CCD cameras installed on site. Then we can the actual parameter data and allowable deviation parameters of the slab by using the host system software part, so as to realize the alarm control. The measuring principle of the system The slab/strip width measuring system is mainly composed of a hardware system and a software system. The hardware system includes two line scan cameras which can scan and image for the casting billet, and the arithmetic unit calculates the absolute position and width of the casting billet by the measurement data collected by the line scan cameras. If a color camera is used, the temperature of the slab can be measured at the same time and transmitted to the host system of the width measuring device. The software in the host system calculates the actual width of the slab and the width at room temperature according to the data of the arithmetic logic unit, and displays the relevant data and change curve, then alarm according to the deviation threshold set by the software system or manually. The software system is mainly used to analyze and process the measurement data collected by the hardware system, display the casting billet data analyzed by the software through the display panel, and send control and alarm to the hardware system instruction. When measuring with a line scan camera, the width measuring device uses two cameras to measure the object at the same time from different angles. The two cameras are like human eyes, which can form stereo vision, so that the sufficient information can be got to judge the distance of the measured object. Correcting and eliminating the effect of distance changes on measurements. From the positions of the two edges of the measured object in the two cameras and geometric derivation, the positions P1(x1, y1) and P2 (x2, y2) of the strip edge in the X-Y coordinate space can be calculated, and the width of the measured object is the straight-line distance between P1 and P2 W=|P1P2|=√ [(x1-x2)^2+(y1-y2)^2] The features of the system It can effectively identify and compensate the beating, inclination, side deflection and profile of the tested plate; Three-layer high temperature protection of air-cooled, water-cooled and outer interlayer asbestos; Moving image linear noise correction technology, electronic exposure technology; With shock-absorbing installation design to reduce measurement errors; The software has self-diagnosis function; Full digital detection, automatic calibration system; Unique optical vibration compensation technology; High measurement accuracy and fast response; Using optical fiber signal transmission; The technical parameters of the system Measuring distance: 2m-10m (according to the on-site environment) Measuring range: 0.05m-40m Resolution: ±0.01mm Repeatability accuracy: 0.05mm Measurement output frequency: 30Hz (adjustable) Laser class: 2 (IEC60825-1:2014) Protection class: IP65 Camera pixel: 8K The measurement range of temperature : 0℃-1200℃ Working temperature: -20℃-60℃

Overview The system realizes the fixed-length measurement of the width, thickness and length of the continuously cast product through machine vision and laser rangefinding system. The measured data is transmitted to the host system through the optical fiber. The host system calculates the weight of each billet according to different steel grades and specific gravity, so that we can realize the fixed length measurement and fixed weight control of the cast products and the precise control of the steelmaking process in the production process. After cutting the billets by fixed weight and length, the fixed weight cut-to-length system is checked by the online weighing measurement system, so as to give feedback to the fixed length model of control system. The slab number (automatic checking) can also be automatically identified online by using machine vision, and the weight and slab number can be automatically stored in the local database for use in the production and management system. The measuring principle of the system On the upper surface of the billet, a set of linear CCD cameras and a laser rangefinding instrument are respectively installed. Through machine vision and laser correction, we can achieve precise measurement of the cast products’ shape. Through accurate cast products’ shape monitoring, the billet thermal expansion coefficient of cast products and cast products’ density at the current temperature, we can obtain the quality of the billet. At the same time, we can achieve high-precision quality cut-to-length , namely, fixed-weight and fixed-length. The system can be matched with the weight detection and calibration system. The system adopts the online barrier-free hidden integral roller table weighing method for continuous casting products, and connects its weighing data into the intelligent control model. The model and steel billet weighing system, and the fixed weight cut-to-length system realize the closed-loop control of the system model, and optimize the fixed weight accuracy through automatic signal collection. The features of the equipment The cutting control technology for fixed-length and fixed-weight of cast products is a concrete manifestation of the lean production management of steel products.
