LAG-S100 LADLE SLAG DETECTION SYSTEM (EDDY CURRENT) IN DELHI

Description 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. System control flow chart 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
