基质组成对低水泥浇注料荷重软化温度的影响

Effect of Matrix Component on Refractoriness under Load of Low Cement Castables

研究了基质组成对低水泥浇注料高温荷重软化温度的影响 .结果表明 ,用铝 80铝酸钙水泥代替铝 70铝酸钙水泥可显著提高荷重软化温度 ;伴随α Al2 O3 加入量增加 ,荷重软化温度提高 ;蓝晶石加入d和 2d时能提高 0 6 %变形温度 ,超过 2d时却有降低作用 .4%变形温度随着蓝晶石加入量的增加而提高 .

This article studies the effect of matrix component on refractoriness under load(RUL) of low cement castables.The result shows that the RUL can be heightened greatly when Al 2O 3?80 calcium aluminate cement replaces Al 2O 3?70 calcium aluminate cement.The RUL raises with the adding of α?Al 2O 3.The 4% deformation temperature raise with the adding of cyanite.Only when the amount of cyanite is d or 2d,can the 0 6% deformation temperature heighten.
