Carbon silicon analyzer for molten iron in front of the casting furnace

One Application Principle

Carbon silicon analyzer for molten iron in front of the casting furnaceIt is a new generation of furnace front molten iron management instrument produced by our company with stable performance and high measurement accuracy. It captures a large amount of thermal effect information of molten iron solidification in real time through the cooling curve of the temperature variation of molten iron tissue in the sample cup over time. Through a series of complex data processing, it quickly and accurately determines the carbon content, silicon content, carbon equivalent, tensile strength, primary crystallization temperature, and eutectic temperature in the molten iron.

The difference between thermal analyzer and spectroscopic chemical analysis is that thermal analyzer measures the process of formation of cast iron structure, which is the comprehensive result of the effect of different contents of all elements in the molten iron on the formation of cast iron structure, and detects the effective equivalent content in the molten iron.

It is impossible to accurately measure each element that accumulates in the molten iron, determine the specific content of each element in the molten iron, and determine the direction and degree of the effect of each element content on the formation of cast iron structure within the waiting time of the molten iron in front of the furnace. Even if it is possible, it is impossible to adjust the content of each element within the specified range.

The thermal analyzer can directly measure the comprehensive effect of different element contents on the formation of cast iron structure, and adjust the comprehensive effect results directly to achieve the expected cast iron structure. This is the advantage of the thermal analyzer compared to other detection methods, and also the reason why it is widely used in developed casting factories.

The detection time is about 2 minutes, and the detection is completed within the waiting time of the molten iron. Then, the composition of the molten iron is adjusted according to the automatically calculated amount of carburizer, ferrosilicon, and scrap steel, and the appropriate composition of the molten iron is obtained before casting.
