Compressive Strength of Vanadium Titanium Magnetite

Abstract: The Taguchi method was used to explore the important influence factors on the compressive strength of vanadium titanium magnetite hot briquettes, and then the contribution rates of these factors to the compressive strength were calculated through the signal-to-noise ratio analysis. Finally, the best preparation conditions of vanadium titanium magnetite hot briquettes were
