主 题：Iron ore granule Crushing strength Young's modulus Taguchi method
摘 要：The contributions of three operating parameters(moisture content,hydrated lime addition,magnetite concentrate substitution)to the crushing strength and Young s modulus of granules in each stage of iron ore sintering were studied by applying the Taguchi *** results indicated that the strength properties of the iron ore granules were greatly affected by its structure,which is composed of inner nuclei and an outer adhering *** granules with a thick adhering layer showed a clear changing trend in strength with increasing temperature,whereas those with a thin adhering layer showed additional fluctuations as their force-displacement responses were greatly determined by the *** granules with a thick adhering layer were gen erally more deformable and easier to break than that those with the thin adhering layer in most *** signal-to-noise ratio and variance analysis indicated that moisture was the dominant parameter affecting the strength properties of the iron ore granules,as this factor controls the primary granule structure and material *** the progress of sintering,the contribution of moisture to the quality characteristics gradually decreased(from〜80%to 50%),whereas the contributions of hydrated lime and magnetite concentrate increased correspondingly(from〜5%to 20%).
