<p>The present invention relates to a method for preparing iron silicate slags, by means of mixing with ferroalloy slag, to a molten slag which can be defibrated into fire-resistant and chemically resistant fibers. The advantageous composition for the molten slag is 15-25% Fe, 45-69% SiO2, 0-5% CaO, 4-10% MgO, 5-15% Al2O3 and 0.5-3% Cr (percentages by weight).</p> |
