Overview: LGK-S107 analog heat source instrument (heating tool) is independently developed and designed by Wuhan CenterRise M&C CO., Ltd. This instrument is a heating and testing equipment used to test the performance of the thermocouples installed in the mold in continuous casting machine. After the installation of the mold breakout prediction thermocouples completed, the analog heat source instrument is used to test these thermocouples 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 thermocouples is consistent, so as to judge the overall status of thermocouples 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. The working principle: The heating tool generates high heat by 220v alternating current and the electric heating element. The heat is transmitted to the copper plate of the mold through the copper head to simulate the heat source of molten steel, so that the thermocouples of the mold can sense the temperature change to achieve the purpose of calibrating the temperature measurement system. The composition: Walking trolley mechanism Preloader Pure copper heating contacts PID thermostat High power heating tube high power driver The parameters: Power supply: AC220V 50Hz Total power: 2200W Single point power: 300W Temperature control accuracy: 1°C Temperature control range: 0°C-500°C Common temperature range: 25°C-300°C Heating points: 3 (points can be customized) Heating method: heating tube heating Heating contact material: copper

Overview: Mold powder is mainly used in the continuous casting and steelmaking process, evenly sprinkled on the molten steel surface in the mold to lubricate, keep warm, prevent oxidation and absorb non-metallic inclusions. Mold powder is an indispensable auxiliary production material in the production process. In the process of evenly distributing the mold powder to the molten steel surface of the mold, the amount of mold powder should be controlled, and the thickness of the mold powder should be within a certain range. If the coverage thickness of the mold flux is too thin, it will cause no heat preservation, oxidation of molten steel, inclusions, cracks, large drawing resistance, steel leakage, etc. At the same time, the coverage thickness of mold flux should not be too thick, they can’t melt in time with too much mold powder, if the molten steel is churning, it is easy to get the mold powder into molten steel at this time, resulting in mold leakage. Therefore, the amount of mold powder must be controlled within a reasonable range. The detection and control of mold flux thickness is very important, especially for the steel plants which are strict with the steelmaking production process. The detection principle: The mold flux detection system developed by Wuhan CenterRise M&C Engineering CO., Ltd. uses the laser triangular sensor fixedly installed above the mold to obtain the height h1 by scanning the upper surface layer of mold flux with high-precision laser triangulation. When the laser measuring head is placed each time, the height h3 of the upper nozzle of the mold will be marked, and the system through the PLC system which is connected to the continuous casting machine through the network to introduce the height h1 of the mold liquid level. Through the calculation of three heights, we can get the thickness of mold powder H = 900-h1-(h3-h2)mm (900mm is the depth of mold). The features: The system adopts a high-precision laser triangulation distance meter, which can measure the thickness of the mold flux with high speed and high precision, and the accuracy can reach 1mm. The equipment is easy to install and use. When we are using, the laser rangefinding sensor can be placed directly above the mold without affecting production. The system can be interlocked with the automatic mold powder feeding system to automatically adjust the amount of mold powder, so as to automatically control the amount of mold powder within a reasonable range and realize intelligent automatic mold powder feeding. Non-contact measurement, the system only needs ventilation protection, simple and stable to use. The parameters: Measurement range:0-50mm Temperature measurement range: -20℃-700℃ Equipment installation distance:750mm System measurement accuracy:1mm Laser measurement accuracy: 0.1mm Frequency: 700-2000Hz Cooling method: air-cooled purging Installation method: rail sliding installation, can be slid out during maintenance Storage period: data can be stored for more than 2 years Communication method: Industrial Ethernet or Profibus-DP

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 0.10s), high detection accuracy (±05mm), and large measurement range (0-150mm). The selected electromagnetic field frequency ensures that the level detection probe only detects the level change of the mold and does not detect the mold flux or steel slag layer. The system has the advantages of simple operation and no radiation protection problems. The system is insensitive to argon blowing, and its sensors can be mounted on the tundish car or on the platform. The sensor is cooled by compressed air during use. The principle is shown in the figure A high-frequency exciting winding is installed above the molten steel surface of the mold. The high-frequency magnetic field generated by the high-frequency exciting winding induces eddy currents on the molten steel surface to form a magnetic field. The magnetic field generated by the induced eddy current is in the opposite direction to the magnetic field generated by the high-frequency exciting winding, which changes the impedance of the high-frequency exciting winding. Under the condition that the winding material and structure, steel grade, temperature remain unchanged, the coil impedance change only has a single-value function relationship with the height of the molten steel level. As long as the impedance change of the high-frequency winding is detected, the change of the molten steel level in the mold can be converted. The components of the system Continuous casting mold level automatic control system is composed of eddy current tyoe molten steel level gauge, controller and digital actuator for adjusting the opening of tundish stopper. The detection end of the mold level automatic control system is ① eddy current displacement sensor, which uses the eddy current mutual inductance effect between the energized coil and the metal conductor to detect the distance. The effective signal of the eddy current sensor is amplified and linearized by the circuit of ② mold level gauge, which converts the 0-150mm change in the molten steel level of the mold into a standard signal of 4-20mA.DC, and then transmits it to the ③ control computer to complete data processing and system control functions. We can also control the actuator manually and automatically through the ④on-site operation display control panel, and the opening of the stopper is controlled by the ⑤ actuator to realize the automatic control of the molten steel level. 1 Eddy current sensor; 2 mold level gauge; 3 control computer; 4 On-site operation display control panel; 5 digital actuator; The control principle of the system The system can be set to four control modes: automatic, semi-automatic, manual and motor clutch. The automatic mode is the closed-loop control system of the molten steel level, and control the opening of the stopper by the digital actuator; the semi-automatic mode uses opening degree setter and digital actuator to set the opening of the stopper manually; the manual mode is to open and close the button directly to control the opening of the stopper; the motor clutch mode is quickly changed from any of the above control methods to manual stopper operation. The functions of the system also include: display and record of molten steel level, nozzle opening and casting speed; setting of molten steel level and nozzle opening; alarm of molten steel level at limit value etc. In addition to taking the detection of molten steel level as the main feedback signal of the control system, the control system also considers various interference factors that have an impact on the level control. These interference factors include: 1. The influence of the change of the flow characteristics on the control system after the melt loss of the stopper 2. The influence of the weight change of molten steel in the tundish on the control system 3. The influence of the change of the casting speed of the continuous casting machine on the control system 4. The influence of the mold width change (the mold width is adjustable) on the control system 5. The influence of the vibration frequency and amplitude of the mold on the molten steel level gauge The function and software implementation In order to overcome these disturbances, the mold level control strategy adopts PID control. And on the basis of PID control, self-adaptive correction and feedforward control are introduced to form an advanced control system. The level control is the main loop, and there is a proportional gain of the main loop controller. According to the self-adaptive correction of the mold width change and feedforward compensation of casting speed, so as to further reduce and eliminate liquid level fluctuations caused by mold width adjustment and casting speed changes. In order to reduce the frequent action of the stopper, the system adopts the intergarting time change of the controller, and automatically selects a longer intergarting time when the molten steel level fluctuates lightly. And the system will choose a shorter intergrating time when molten steel level fluctuates greatly. Thereby, the fluctuation of the controlled object caused by the frequent action of the stopper rod is suppressed. In the signal processing of molten steel level gauge, an appropriate filtering link is added and the vibration frequency synchronous filter is used for filtering processing, which can overcome the interference of mold vibration frequency and amplitude variation.
