针对高炉渣滚筒法干式处理工艺,用液态石蜡模拟高炉融渣,研究了粘度和滚筒转速对凝固层厚度的影响规律。结果表明:凝固形成的蜡层厚度随熔体粘度的升高而变大,随滚筒转速的增加而变小;凝固层厚度随熔体粘度与滚筒转速的变化关系满足拟合公式:δ=15.43√μ/ρνL。
Liquid paraffin instead of molten slag was cooled by rotating drum for simulating blast furnace slag rapid solidification process. The influence of viscosity and rotating speed on the thickness of the solidified paraffin were investigated. The results show that the thickness of the solidified paraffin increases with the increase of the viscosity of melt and decreases with the increase of the rotating speed of drum. The thickness as a function of viscosity and rotating speed can be expressed as a semi-empirical formula: δ=15.43√μ/ρνL .
