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.

Mould Online Width Adjustment and Taper Measurement



Overview

In order to meet the needs of producing various specifications of continuously cast products, shorten the time for replacing the mold, and improve the production capacity and production efficiency of the continuous casting machine, the mold online width adjustment system is the key technology for efficient continuous casting. The online mold width adjustment system enables the two narrow sides of the continuous casting slab mold to move inward or outward in small steps until the predetermined width is reached. During the production process, the adjustment of the mold s width can be completed without stopping the machine. Generally, the online width adjustment of the mold needs to be connected with the online taper measurement of the mold. Only with adjustment and detection can the online adjustment range of the mold be accurately controlled.







The components of the system

Workstation: host system, system width adjustment control, taper detection.

On-site operation box: real-time display of the current control status, manual operation to adjust parameters.

Digital Electric Cylinder: Precise digital control of electro-hydraulic drive cylinder, which can achieve high-precision quantitative control.

On-line measurement of taper: Install it on the narrow-face copper plate of the mold, and monitor the taper of the narrow-face copper plate in real time. Cooperate with the detection feedback control of the width adjustment system, so as to achieve high-precision adjustment.





The technical parameters

Adjustable range: 0-1250mm (unilateral)

Control accuracy: 0.02mm/0.05mm/0.1mm

Step resolution: 0.01mm/0.02mm

Running speed: 0-10mm/s

Power: 3.5KWl

16-bit encoder: 65536 pulses

Weight: 25Kg

Shell: high-strength aluminum alloy


The functions of the system

Realize online width adjustment function

Realize the online real-time monitoring function of mold taper

Continuous casting production adjustment and non-stop production

One-key operation in the main control room, automatic completion

High adjustment accuracy and fast speed

The interlock control of the continuous casting steelmaking system can realize automatic steel pouring

As an efficient sample pretreatment method, microwave digestion has the advantages of fast heating speed, uniform heating, less reagent consumption, low blank, energy saving and high efficiency compared with traditional electric plate digestion.
advantage:
1. 360 continuous rotation platform: the digestion tank assembly can continuously rotate in the same direction in the furnace chamber, solving the unequal and uneven heating of different tank positions by microwave; At the same time, the continuous rotation mode reduces the impact of less than 360 reciprocating rotation mode on the rotating motor in the market, and greatly extends the life of the motor.
2. Peripheral emergency stop button: ensure that the power supply can be cut off quickly, timely and effectively in case of accidents, and improve the guarantee level for the personal safety of operators.
3. Digestion tank material: the sample digestion tank material is processed by imported modified polytetrafluoroethylene TFM, and the protective outer tank is made of imported PEEK+glass fiber, with high temperature resistance and pressure resistance coefficient, acid and alkali resistance and superior solution performance, and high safety factor.
