LAG-S100 Ladle Slag Detection System (Eddy Current)
Overview
The continuous casting 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 electromagnetic induction detection.
The meaning of slag detection
To achieve high output: In order to ensure the cleanliness of molten steel in the ladle, if we detect slag by eyes, we often close the ladle prematurely, so that it will reduce the yield of molten steel. However, if we use slag detection system, we can detect slag accurately and timely, so that the amount of residual steel is controlled at 1%-2% to achieve high output.
Improve the cleanliness of molten steel: The steelmaking slag gets into the tundish is the main reason that affects the cleanliness of finished steel. The use of the slag detection system can reduce the amount of steelmaking slag carried into the tundish to a very small amount, and can also reduce the defects on the slab surface at least 80%.
Avoid blockage of the nozzle: The steelmaking slag gets into the tundish is also the main reason for the blockage of the nozzle due to secondary oxidation. After using the slag detection system, the blockage of the nozzle can be greatly reduced.
The composition of the system
The slag detection system mainly consists of five parts: sensor, preamplifier, signal processing unit, central processing unit and platform control box.

The working principle of the sensor
The sensor adopts the principle of electromagnetic induction for signal detection, and its typical structure is two concentric coils. When the primary coil is supplied with an intermediate frequency excitation current, due to the action of the magnetic field, an eddy current is generated in the steel flow, and the direction of the magnetic field is opposite to the direction of the magnetic field generated by the coil. Because the conductivity of slag is much lower than that of molten steel at high temperature (about 1/1000), the eddy currents generated in slag are much smaller than those generated in molten steel. In the process of pouring steel, all the molten steel flows out at the beginning of pouring. At the later stage of pouring, there will be steelmaking slag mixing out, which reduces the conductivity of the melt and enhances the electromagnetic field. This signal is measured by the secondary coil.
The principle of sensor construction
The primary coil and the secondary coil are isolated by high temperature resistant materials, and the coils are encapsulated in a flat ring made of special steel as a whole. Then two pairs of signal lines are drawn from the two-pole coil using a unique technical method, and sent to the secondary part.
The installation of the sensor
The sensor is installed in the ladle reference plate, coaxial with the ladle nozzle, and acts as a guide part for the ladle nozzle casing tube at the same time.
