MLC-V235 Continuous Casting Mold Level Automatic Measurement System
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
Transformer oil acid tester is a fully automatic measuring instrument which adopts the extraction method to accurately detect the insulating oil acid value. This instrument can improve the working efficiency and test accuracy, and at the same time ensure the safety of the body by reducing the operator's contact with the samples and reagents.
The acid value is the trace value of potassium sulfate that neutralizes the petroleum acid in 1g of oil, which contains a certain amount of inorganic acid and inorganic acid. The acid value includes organic and inorganic acids contained in the oil. In most cases, oil does not contain mineral acids. Therefore, the oleic acid value actually represents the content of organic acids in the oil. The organic acid contained in the new oil is mainly cyclonic acid. In the oil and in the process of use, the acid value of the oil produced by oxidation is an indicator to measure the degree of refining of the new oil. Whether the oil is running is an important indicator of the continued use of oil quality equipment.

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.
The structure of the instrument
Continuous casting mold oscillation and deflection detection instrument is mainly composed of sensor system, sensor signal conditioning circuit, power supply circuit, synchronous data acquisition module, communication cable, and software data analysis system.
There are three axial acceleration sensors installed in the mold oscillation and deflection detection instrument, one of which is to detect the vertical oscillation signal (Y axis), and the other two are to detect the horizontal oscillation signal (X and Z axis). The signal obtained by the sensor is processed by the preprocessor and the preprocessing module. The oscillation signal and sensor status signal will be filtered and normalized, sent to the synchronous data collector for digitization and feature extraction, and the data is analyzed and processed by the master computer software to obtain various oscillation parameters and process parameters required by users.

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.
The handheld roll gap checker is specially used to measure the length between spherical surface, arc surface and plane (or spherical surface). It is specially suitable for the opening adjustment of the roll gap of the metallurgical continuous casters in various specifications, because the roll gap checker has the advantages of high resolution, accurate measurement, stable data and easy to use. Because the opening accuracy of the roll gap checker will directly affect the quality of the casting block, this roll gap checker is an indispensable testing equipment in the continuous casting equipment, which can fully meet the needs of on-site installation testing and use process verification. When the hand-held roll gap meter smoothly passes through the gap between the guide rolls of the continuous casting machine, the upper measuring contact of the hand-held roll gap checker contacts the inner arc roll and the lower measuring contact touches the outer arc roll. The handheld roll gap checker is used in perpendicular to the roll diameter direction, during the pushing process, when the hand-held roll gap meter is in the tangent plane of the upper and lower rolls, the measured value is the smallest at this time, and this value is the roll gap measurement value. The design of the hand-held roll gap gauge ensures that the upper and lower contacts of the roll gap checker can smoothly pass the measured roll along a straight line during measurement.
During the measurement process, the roll gap measuring instrument automatically compares the measured values, and displays the minimum measured value on the instrument display interface, which is the current measured roll gap value.
