CYY-LK2 Fast Furnace-Side Carbon-Silicon Analyzer

CYY-LK2 is a professional carbon-silicon analyzer, the core equipment of Changyouyi for analyzing carbon (C) and silicon (Si) content in molten iron just before the furnace. This device belongs to the pre-tap iron thermal analyzer series and uses thermal analysis methods to quickly determine the chemical composition of molten iron.

In the iron casting workshop, controlling the carbon and silicon content of molten iron is critical to determining the quality of cast products. C and Si levels directly impact: - The microstructure of the iron (gray, ductile, or white iron) - Mechanical properties of the castings (hardness, strength, ductility) - Post-casting machinability - Defect rates and production efficiency

CYY-LK2 helps control the carbon content in molten iron before casting, reducing defect rates and improving production efficiency. The device analyzes C and Si levels in liquid iron in as little as 240 seconds.

Display and print results

CYY-LK2 has two result display formats:

1. LED Display: 4-digit LED display with 50mm character height, ensuring clear visibility in foundry environments. Operators can: - Press the button to display carbon equivalent (CEL) - Press the button to display carbon content (C%) - Press the button to display silicon content (Si%) - Press the cycle button to sequentially display CEL, C%, and Si%

2. Embedded thermal printer: The device features an automatic embedded thermal printer that prints results. Key features: - Automatically prints when paper is available - Stops printing when paper runs out, but does not affect the LED display of numbers - Printed output is entirely in English, including: measured temperature, carbon content, silicon content, carbon equivalent, hardness estimation, tensile strength, and other parameters - The printout serves as the official and most complete record of results

The device control panel is currently in mixed Chinese-English format and will be fully upgraded to English in the upcoming version.

What is a carbon-silicon analyzer?

The carbon-silicon analyzer is a specialized device used to measure the carbon and silicon content in molten iron.

Traditional chemical analysis methods may require laboratory setup and longer testing times.

Pre-furnace carbon-silicon analyzer provides real-time, direct data during production, enabling operators to immediately control molten iron composition.

Why is controlling carbon and silicon important

In cast iron production, carbon and silicon directly affect: - Graphite structure - Fluidity - Hardness - Tensile strength - Machinability - Casting defects

Inaccurate carbon or silicon content can cause: - Poor casting quality - Excessive hardness - Low strength - Defective microstructure

CYY-LK2 helps maintain stable chemical composition.

Main functions of the carbon silicon analyzer CYY-LK2

Measure carbon content (C%)

Carbon content analyzer to help control: - Graphite formation - Solidification behavior - Mechanical properties

Measure silicon content (Si%)

Silicon dosage optimization: - Ferrite formation - Fluidity - Casting efficiency

Calculate Carbon Equivalent (CEL)

Carbon equivalent is automatically calculated based on measured thermal properties.

This provides a quick assessment of the molten iron condition.

Predict tensile strength and hardness

For non-alloy cast iron, the system can estimate: - Tensile strength (RM) - Hardness (HB)

Help foundries improve process control.
