摘要/Abstract

摘要： 测量了某种烧结矿料的真密度、孔隙率及等效导热系数，研究了烧结矿等效导热系数随温度的变化规律. 结果表明，烧结矿等效导热系数在323~750 K随温度升高而上升，在约750 K达到最大值，温度再升高，烧结矿发生部分相变，导致导热系数下降. 实际烧结冷却过程中烧结矿温度低于723 K，模拟得出323~723 K下烧结矿固体导热系数呈线性增长，验证了测量结果优于经验值.

Abstract: A sinter’s density, porosity and equivalent thermal conductivity were measured. The variation of equivalent thermal conductivity with temperature was studied. The results showed that equivalent thermal conductivity increased with temperature during 323~750 K and reached a peak near 750 K. After the temperature rised above 750 K, part of sinter melted with equivalent thermal conductivity reduced. The temperature of sinter at actual cooling process was below 723 K. Simulated results showed that with the rising of temperature solid thermal conductivity increased linearly from 323 K to 723 K, Numerical simulation of equivalent thermal conductivity validated by experimental measurement were better than the experience value.

Key words: equivalent thermal conductivity, sintering, porous media, numerical simulation
