Overview The continuous casting vibration type ladle slag detection device is used to detect the slag content of the ladle nozzle in the steelmaking continuous casting process, so as to improve the cleanliness of the tundish molten steel and obtain the best yield of the ladle molten steel. The device adopts the principle of vibration detection. The LAG-S200 continuous casting ladle slag automatic detection system is developed by Wuhan CenterRise M&C Engineering Co., Ltd. after many years of research with many scientific research institutes, and fully combined with the actual situation on site. It has a real field application value as a continuous casting ladle slag automatic detection system. The meaning of the system 1. Reduce the amount of tundish slag 2. Improve the purity of molten steel 3. Improve the life of the tundish 4. Reduce sliding nozzle erosion 5. Reduce nozzle blockage 6. Increase continuous pouring heats 7. Reduce the amount of residual steel in the ladle when high-quality steel is casting 8. Improve the yield of molten steel 9. Improve the quality of continuous casting billets In order to improve the purity of the molten steel in the tundish, and improve the quality of the casting billet, especially to improve the quality of the billet in the transition section, and reduce the amount of residual steel in the high-quality ladle, and prolong the life of the tundish lining, and increase the continuous casting heats, it’s necessary to detect and control the slag in the later stage of continuous casting ladle casting. The working principle The LAG-S200 continuous casting ladle slag automatic monitoring system detects the slag state during the pouring process by receiving the vibration signal of the mechanical operating arm of the ladle nozzle. In the process of molten steel pouring, when molten steel flows through the long nozzle and pours into the tundish, the molten steel impacts the wall of the long nozzle and causes the vibration of the mechanical operating arm used to support the long nozzle. Since the specific gravity of the steelmaking slag is less than half of the specific gravity of the molten steel, it floats on the surface of the molten steel, and the steelmaking slag appears when the molten steel is about to be all poured. At this time, due to the high viscosity and poor fluidity of light steelmaking slag, the impact force of the mixed flow of molten steel and steel slag on the wall of the long nozzle is quite different from that of pure molten steel. The system mainly monitors the ladle slag of the continuous casting by measuring and analyzing the vibration difference of the mechanical operating arm. The vibration signal is connected to the operation control unit of the system control cabinet through the front-stage conditioning and amplification module through the sensor installed in the middle of the operating rod. After processing, it is output to the industrial computer for operation and analysis. The slag signal detected by the system is output from the system control cabinet to the front-end control unit, and then control the alarm horn and alarm light to work, or issue an instruction to close the ladle nozzle. The features of the system (1) It is easy to install, basically no modification is made to the field equipment, and the installation and debugging work will not affect the normal production of the enterprise. (2) The detection accuracy is high, and the effective rate is greater than or equal to 95%. The threshold of slag volume is accurately set, the output control function is powerful. It has excellent performance in technical indicators such as the sensor service life and sensor usage times. (3) The sensor is installed at a position far away from the molten steel, and is cooled by a special refrigeration device for 24 hours. The outer layer adopts a composite protection structure, which has a long service life. (4) Adopt professional and targeted signal processing methods to obtain the vibration characteristic parameters of the ladle slag, and analyze, reason and judge the effective slag signal through the vibration signal database, which has a high accuracy of slag alarm. (5) The architecture is established based on the artificial intelligence network, which has the functions of self-learning and self-induction. (6) The equipment adopts a modular design. The failure of each module will not affect other parts, which ensure more reliable operation of the system and easy maintenance. (7) The alarm display device is used on site to visually indicate the flow state of molten steel and slag. When slag carryover strats, we can choose automatic mode or manual mode. In both modes, the system will give audible and visual alarm signals to remind on-site operators. (8) The system has a powerful database function. Including the comparison function for last two ladles of casting time record, the system automatically stores the running data, and generates a record file every day. (9) The system has the function of automatically controlling the ladle nozzle. The control unit is an auxiliary system of the system, which is interconnected with the ladle slag detection system to automatically control the opening of the ladle nozzle and realize the whole-process control of the liquid level of the molten steel in the tundish. The composition of the system The LAG-S200 slag detection system consists of: vibration detection sensor, pre-signal amplifier, slag detection operation unit, tundish liquid level control unit, on-site operation indication box, and process control cabinet. 1. Vibration detection sensor: It is installed on the robotic arm of the stopper to detect the vibration signal of the whole casting process of the ladle. 2. Pre-signal amplifier: Amplify, convert and transmit the weak vibration signal detected by the vibration detection sensor. 3. Slag detection operation unit: Analyze, judge and discriminate the vibration signal to realize the discrimination of all steel, mixed slag and full slag , and output the slag alarm signal. 4. Tundish liquid level control unit: Accept the control signal of the tundish nozzle and the ladle nozzle, and realize automatic or manual control to the ladle slag according to the requirements. 5. On-site operation instruction box: Provides man-machine exchange for slag alarm indication, fault indication, system activation mode selection, and control mode selection. 6. Process control cabinet, providing power management, displaying man-machine interface and setting management. The parameters of the system 1. The system controls the slag inclusion in molten steel with high precision and closes the nozzle in real time. 2. Improve the quality of steel, reduce defective products, and improve the yield. 3. The yield of molten steel is increased by 0.3%-0.5%. The nozzle can be automatically closed, so that the disadvantage of untimely manual response is overcome and less molten steel remains in the ladle. The threshold value of molten steel (slag threshold) is set by the user within a wide range. 4. No artificial factors are involved, high reliability, good repeatability or consistency. 5. The steelmaking slag does not pass through or rarely flows into the tundish, which increases the service life of the refractory material and the sliding nozzle. 6. Reduce the blockage of the tundish nozzle and increase the number of continuous pouring heats of the tundish.

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 infrared converter slag detection system uses a far-infrared thermal imager to monitor the situation of converter tapping in real time, and is connected to the main control computer in the electrical room through the conversion and transmission of video signals. The radiation intensity in the infrared wavelength range of 7-14um is different to distinguish molten steel and slag. In the later stage of the converter tapping, the molten steel gradually decreases, and the steelmaking slag is involved in the molten steel and flows out of the tapping hole. After the thermal imager recognizes the steelmaking slag in the imaging temperature measurement, it will give an alarm according to the slag content ratio threshold set by the software. The thermal imager will start the slide plate to close the tapping hole, so as to realize the control of the slag in the converter tapping, and ensure the maximum yield of molten steel and the minimum control of the steelmaking slag content. The effect of slag detection in converter tapping is of great significance to the control effect of the slag amount. The converter slag detection and control system developed by our company conducts non-contact monitoring of the tapping steel flow through the far-infrared detector thermal imager. It can detect the slag condition in real time and output an alarm signal and control system, which can replace manual visual inspection and provide accurate, efficient and stable slag detection effect. When the system finds the slag, the intelligent control unit quickly makes a judgment of lifting the furnace and blocking the slag and outputs an alarm signal. As shown in Figure 1, the system includes thermal imager, front purge protection box, front electrical box, power distribution cabinet, main control monitor, monitor of rocking furnace chamber, sound and light alarm, infrared converter slag monitoring software system, etc. The features of thermal imager 1.
