Continuous Casting Mold Flux—Determination of Titanium Dioxide Content—Ferric Ammonium Sulfate Titrimetric Method

This document applies to the determination of titanium dioxide content in continuous casting mold fluxes, within a measurement range of 5.0% to 25.0% (m/m). Relevant testing laboratories and entities engaged in the production, quality control, and inspection of continuous casting mold fluxes shall use the ferric ammonium sulfate titrimetric method to determine titanium dioxide content and conduct sample preparation, titrimetric analysis, and result calculation in accordance with this method standard, so as to ensure the accuracy and comparability of test results.
