Introduction
The GB/T 26416.7-2023 standard, titled "Chemical Analysis Methods for Rare Earth Ferroalloys - Part 7: Determination of Carbon and Sulfur Content - High Frequency-Infrared Absorption Method," provides guidelines for analyzing the carbon and sulfur content in rare earth ferroalloys. This standard utilizes the high frequency-infrared absorption method to measure the levels of carbon and sulfur present in these alloys.
The determination of carbon and sulfur content is crucial in assessing the quality and suitability of rare earth ferroalloys for various industrial applications. Carbon content affects the mechanical properties and stability of the alloys, while sulfur content can adversely impact their corrosion resistance and weldability. Accurate measurement of these elements is, therefore, essential for ensuring the desired performance and reliability of rare earth ferroalloys.
The high frequency-infrared absorption method outlined in this standard offers a reliable and efficient technique for determining carbon and sulfur content. This method involves subjecting the sample to infrared radiation at specific frequencies and analyzing the absorption of this radiation by carbon dioxide and sulfur dioxide gases produced during the combustion of the sample. The measured absorption values are then used to calculate the carbon and sulfur content in the rare earth ferroalloys.
By adhering to the guidelines provided in GB/T 26416.7-2023, manufacturers, researchers, and quality control personnel can accurately analyze the carbon and sulfur content in rare earth ferroalloys, ensuring their compliance with desired specifications and industry standards.
