On 08/10/2026, China Industry News published an article about Changyouyi's participation in the casting equipment exhibition and its introduction of the CYY carbon-silicon analyzer. The article highlights the importance of molten iron composition testing before the furnace for ensuring casting quality.
- Context: Component testing in the lab takes 15-30 minutes; with continuous casting, this delay means adjustments to the iron batch occur after pouring.
- Method: Thermal analysis — Pour a molten iron sample into a cup, record the cooling curve, and calculate C, Si, and CEL in 2-3 minutes directly at the furnace.
- Device: CYY Carbon Silicon Analyzer by Nanjing Changyouyi Analytical Instrument Co., Ltd., featuring domestically sourced components, a Chinese interface, and automatic analysis algorithms.
- Application: gray cast iron, ductile iron (rapid evaluation of spheroidizing efficiency), and process monitoring. Serves agricultural machinery, railroads, heavy equipment, automotive parts, and precision casting industries.
- Industry scale: China produces over 50 million tons of cast iron annually; pre-furnace inspection helps shift the focus from post-production checks to process control.
