Molten Metal Composition Analyzer

Product Specifications

Technical details and manufacturing context for Molten Metal Composition Analyzer

Definition

The Molten Metal Composition Analyzer is an industrial system designed for continuous, in-situ analysis of molten metal composition during basic metal manufacturing processes. It provides real-time data on elemental concentrations such as carbon, silicon, and manganese in furnaces, ladles, or casting lines. This enables precise quality control, reduces off-specification batches, and optimizes alloying additions. The system is engineered for harsh foundry environments with high temperatures and dust.

The analyzer operates using optical emission spectroscopy (OES) or laser-induced breakdown spectroscopy (LIBS) to analyze light emitted from a spark or laser pulse on the molten metal surface, determining elemental composition. It is housed in a stainless steel enclosure with a quartz optical window and a ceramic probe tip, and uses copper electrodes for spark generation. The system includes a spectrometer for spectral analysis.

Key parameters include an analysis time of 2–5 seconds per measurement cycle, a temperature range of 0–50 °C for the molten metal, and detection of elements including Fe, C, Si, Mn, P, S, Cr, Ni, Mo, Cu, Al, and Ti. Measurement precision is ±0.05%, with a measuring range of 0.001–100% for alloying elements. The sampling frequency is 1–10 Hz, and the system operates on a 220 V AC (±10%) single-phase supply, consuming up to 500 W. It requires an inert gas supply at 0.1–0.5 MPa for probe purging. The system has an IP54 ingress protection rating per IEC 60529, and provides RS485 and 4–20 mA analog outputs for process control. The weight ranges from 15–25 kg depending on configuration and probe length.

All listed values are reference ranges and must be verified with the manufacturer for specific models and applications. The system is not certified or compliant solely by listing standards; verification is required.

Working Principle

The analyzer uses optical emission spectroscopy (OES) or laser-induced breakdown spectroscopy (LIBS). In OES, an electric spark is generated between copper electrodes and the molten metal surface, exciting atoms that emit characteristic light. In LIBS, a laser pulse ablates a small amount of material, creating a plasma that emits light. The emitted light is collected through a quartz optical window and directed to a spectrometer, which disperses the light into its component wavelengths. By analyzing the intensity of specific spectral lines, the system determines the concentration of elements such as carbon, silicon, and manganese. The entire measurement cycle takes 2–5 seconds, providing near-real-time data for process control.
