LGK-S107 Analog Heat Source Instrument
Overview:
LGK-S107 analog heat source instrument (heating tool) is independently developed and designed by Wuhan CenterRise M&C CO.,. This instrument is a heating and testing equipment used to test the performance of the couple installed in the mold in continuous casting machine. After the installation of the mold breakout forecast couple is completed, the analog heat source instrument is used to test these couples before they go online. After the thermocouple is connected to the mold thermocouple detector, the current temperature of each thermocouple point will be displayed. By using our heating device to heat the copper plate point of each thermocouple at a fixed point, the thermocouple will have a synchronous temperature rise and then we can observe the temperature rise curve of the same column of temperature points to see whether the temperature measurement consistency of the column of couples is consistent, so as to judge the overall status of couples installed in the mold. If an abnormal point occurs, it needs to be repaired and replaced, so as to ensure the stable operation of the mold breakout prediction system.

LAG-S200 Ladle Slag Detection System (Vibration Type)
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 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 the number of continuous pouring furnaces
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 number of continuous casting furnaces, necessary to detect and control the slag in the later stage of continuous casting ladle casting.
The Working principle of the system
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.

LAG-S400 Infrared Converter Slag Detection System
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.

LDC-X200 Laser Diameter Measurement System
Overview
The non-contact diameter measuring system, is mainly used in the measurement of the outer diameter of various wire rods, bars, wires and pipes. The system can detect the change of the diameter (outer diameter) of the measured object in real time under the high temperature state.
The working principle
The diameter measuring system takes the laser scanning method as an example. It adopts the probe imported from Japan, which can achieve an accuracy of plus or minus 2 microns in the range of 0.3 to 30 mm. The acquisition frequency reaches 2000 times/second. The probe uses a self-excited infrared light source, which overcomes the measurement problem in dim environments.
It adopts the measurement method of pulse parallel light scanning, and has a strong ability to resist the jitter of the measured object. (As shown in Figure 1) Since the shaking frequency of the measured object is much smaller than the scanning frequency, when the measured object A moves in the shakeable area, the measurement result will be able to ensure its accuracy because the time it blocks the beam does not change.
Figure 1: Probe Scanning Radiation Area
The detection principle is as follows
Figure 2: Working Principle
First, the crystal oscillator generates self-excited high-frequency pulses, which are sent to the comparator and the stepping servo motor respectively. The stepping servo motor drives the octahedral prism to rotate at a high speed, and reflects the infrared laser emitted by the laser generator to the convex lens A. It becomes parallel light, and then collects on the photosensitive element C through the convex lens B in the infrared receiving probe. The photosensitive element C converts this signal into a corresponding electrical signal and sends it to the other end of the comparator to compare with the original signal.
When there is no object to be measured in the measuring probe, the pulse signal at both ends of the comparator will be the same. Therefore, there is no difference output: when there is an object to be measured in the measuring probe, the photosensitive element C will output no pulse signal during the period of scanning through the object to be measured. Therefore, there will be a difference input for a period of time at both ends of the comparator, which corresponds to the diameter of the measured object. By calculating the oscillation period of the pulse and the length of the time slice without pulse, the diameter of the measured object can be known.

Mould Oscillation and Deflection Detection Instrument
Overview
The mold is a device that shapes the cast product in continuous steel casting, and it is also the core equipment and key technology of continuous casting machine. The main function of the mould oscillation deflection detection instrument is to detect the the mould oscillation table s oscillation frequency, amplitude, deflection rate, phase, oscillation trajectory curve, etc. Through the detection and adjustment of the detection instrument, the mold moves along the outer arc of the continuous casting machine according to the given amplitude, frequency and waveform deflection characteristics.
The actual oscillation parameters of the mold oscillation table during the operation and production process and the process parameters of the cast products cannot be effectively known without the data detection of the mold deflection detection instrument, so that the operator cannot adjust the mould s production process parameters in real time according to the real-time situation of the on-site production.
The continuous casting mold deflection detection instrument independently developed by our company is suitable for various molds such as slab, square billet, round billet and shaped billet. The system obtains the process parameters such as actual oscillation holographic parameters and negative slip amount of the oscillation table by effectively detecting the movement of the mold. The technicians can formulate the control strategy of the mould according to these actual parameters, and improve the output and quality of the product within a safe and reliable range.

Overview
The automatic control for the molten steel level of the mold is one of the key technologies of continuous casting production. It is very important to reduce the labor intensity of workers, improve production efficiency, improve the quality and output of casting billet, reduce overflow and breakout of steel and improve the management level of steelmaking and continuous casting.
The molten steel is poured into the mold. In order to prevent overflow, the molten steel level must be kept stable. Otherwise, during the casting process, if the level will fluctuate too much, and slag will be involved, forming surface slag inclusion on the surface of the casting billet, affecting the quality of the billet. The test points out that the relationship between the level fluctuation and the depth of casting billet surface slag inclusion is as follows:
The experience has shown that surface slag inclusions can be eliminated when the level fluctuation is within 10mm. At the same time, if the level fluctuation is more than 10mm, the rate of longitudinal cracks on the casting billet surface is 30%. It means that the level fluctuation directly affects the surface quality of the casting billet.
The principle of the system
The eddy current type molten steel level gauge is the key to the system. The system operates reliably and has excellent performance: high temperature resistance, strong anti-interference ability, fast dynamic response (lag time

MDC-K120 Slab Mold Taper Measuring Instrument
Overview
The taper of the narrow face of the mold has an important influence on the quality of the casting billet. Excessive taper will cause the mold to squeeze the billet shell, and a small taper will increase the air gap. With the continuous increase of the requirements of the casting billets quality and the continuous introduction of high-precision molds, the current taper measuring instrument in the domestic market generally have low measurement accuracy and complex measurement methods, which restrict the development of production.
The new-generation taper measuring instrument developed high-precision inclination sensor, combined with ultra-low power consumption processor, which can quickly and accurately measure the actual taper value of the narrow copper plate of the mold. The instrument is fully functional, easy to use and suitable for slab molds of various lengths.
Most of the current slab molds are single-taper, a narrow flat copper plate. The taper value required for production can be achieved by adjusting the angle between the narrow copper plate and the direction of gravity. The taper measuring instrument directly measures the angle between the narrow copper plate and the direction of gravity. According to habits and production needs, the angle is converted into the value of one-sided shrinkage of the upper and lower ports.
