    Reduction Behaviors of Silicon–Ferrite from Calcium and Aluminum in a Hydrogen-Rich Blast Furnace by Keshuai Du, Changqing Hu, Xuefeng Shi, Guangqing Yang

    Published 2024-11-01
    “…The fastest reduction rate was observed at 1273 K. When the hydrogen volume fraction was 6% and the temperatures were 1073 K, 1173 K, and 1273 K, the reaction mechanism followed the 3D diffusion model (G-B), with an apparent activation energy of 32.087 kJ·<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><msup><mi>mol</mi><mrow><mo>−</mo><mn>1</mn></mrow></msup></semantics></math></inline-formula> and a pre-exponential factor of 0.1419. …”
