The on-site molten iron carbon-manganese-silicon analyzer takes the solidification temperature curve during the formation process of cast iron structure as the measured object, analyzes the temperature curve, and calculates the molten iron properties such as carbon equivalent CE%, carbon content C%, silicon content Si%, manganese content Mn%, and spheroidization rate SG% based on the characteristic points of the curve. The detection time is about 1 minute and 30 seconds, 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 dosage of carburant, ferrosilicon, and scrap steel, which effectively guides production practice.

The computer-based on-site rapid thermal analyzer takes the solidification temperature curve during the formation process of cast iron structure as the measured object. The computer analyzes the solidification temperature curve to calculate indicators such as carbon equivalent (CE), carbon content (C%), silicon content (Si%), spheroidization rate (SG%), and tensile strength (RM) of the molten iron. The composition of the molten iron is adjusted according to the automatically calculated dosage of carburant, ferrosilicon, and scrap steel. The on-site molten iron quality management instrument is an effective way to realize the optimal control of casting quality.

The computerized carbon-silicon analyzer is a new generation of on-site molten iron management instrument produced by our factory with stable performance and high measurement accuracy. It captures a large amount of thermal effect information of molten iron solidification in real-time, quickly, and accurately through the cooling curve of the temperature of the molten iron structure 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, primary crystal temperature, and eutectic temperature in the molten iron.
