应用瞬态热线法导热系数测量装置，测定了含硼炉渣的导热系数。获得了导热系数与温度的关系，及组成对导热系数的影响。在低温区导热系数随着温度的升高而呈直线形式略有增加；在高温区导热系数随着温度的升高而迅速降低。在所研究的组成中，随着碱度R=CaO/SiO2的增加，含硼炉渣的导热系数减少；在碱度R=CaO/SiO不变时，随着MgO含量的增加，含硼炉渣的导热系数增加；随着B2O3含量的增加，导热系数呈现出不规则的变化。为提高含硼炉渣硼的提取率提供了基础数据和依据。

The transient heat wire method was applied to measure the thermal conductivity of the boron-containing slag, and the relationship of thermal conductivity with temperature and composition was obtained. The thermal conductivity increased slightly with the elevation of temperature in the low temperature zone, the thermal conductivity decreased rapidly with the elevation of temperature in the high temperature zone. The thermal conductivity of the boron-containing slag decreased with the increase of R=CaO/SiO2. The thermal conductivity of the boron-containing slag increased with the increase of MgO content when R=CaO/SiO2 was constant. It provided basic data and reference for increasing rate of extraction of the B2O3 bearing slag.
