LC-QCR3000 Online Molten Iron Rapid Analyzer
I. Principle Overview
The LC-QCR3000 Online Molten Iron Rapid Analyzer is a new generation of molten iron management instrument with higher measurement accuracy and more stable performance. The rapid thermal analysis technology for cast iron is based on the solidification temperature curve of the cast iron structure formation process. Mathematical analysis of the solidification temperature curve yields characteristic points of the curve under different compositions. According to a pre-established mathematical model, it calculates the carbon equivalent (CE), carbon content (C%), silicon content (Si%), and other indicators of molten iron. This technology provides a simple, fast, and accurate instrument for use in cast iron production. The thermal analyzer takes about 2 minutes to complete the detection within the waiting time of the molten iron. Based on the automatically calculated amounts of carburizer, ferrosilicon, and scrap steel to be added, the composition of the molten iron is adjusted to achieve the suitable composition before pouring. The instrument operates on Chinese voltage 220V 50Hz.
