LC-TS5 Molten Iron Composition Analyzer

I. Application Principle

The LC-TS5 Molten Iron Composition Analyzer is a new-generation molten iron management instrument produced by our company, featuring stable performance and high measurement accuracy. It captures a large amount of thermal effect information during the solidification of molten iron in real-time, quickly, and accurately by analyzing the cooling curve of the molten iron's microstructure in the sample cup over time. Through a series of complex data processing, it rapidly and accurately determines the carbon content, silicon content, carbon equivalent, tensile strength, initial crystallization temperature, and eutectic temperature of the molten iron.

Unlike spectrochemical analysis, thermal analysis measures the process of cast iron microstructure formation, which is the comprehensive result of the influence of all elements in the molten iron on the formation of the cast iron structure. It detects the effective equivalent content in the molten iron.

Accurately measuring each element concentrated in the molten iron, determining the specific content of each element, and understanding the direction and extent of each element's influence on the formation of the cast iron structure are tasks that cannot be completed within the time available for molten iron treatment in front of the furnace. Even if possible, adjusting the content of each element to the specified range is impractical.

Thermal analysis, however, can directly measure the comprehensive effect of different contents of all elements on the formation of the cast iron structure and directly adjust the comprehensive result to achieve the desired cast iron microstructure. This is the advantage of thermal analysis compared to other detection methods and the reason for its widespread adoption in foundries in developed countries.

The detection time of the LC-TS5 Molten Iron Composition Analyzer is approximately 2 minutes, completing the analysis within the time available for molten iron treatment. Based on the automatically calculated amounts of carburizer, ferrosilicon, and scrap steel to be added, the composition of the molten iron is adjusted. After obtaining the suitable molten iron composition, casting can proceed.
