摘　　要：在还原气氛中，研究了两组不同CaO含量的不合石墨及合石墨的不烧镁钙（炭）试样的高温荷重软化性能，发现不烧镁钙炭砖的荷重软化温度有可能高于镁炭砖。At reduction atmosphere, the investigation on high temperature refractoriness under load of two series unfiredMgO-CaO(-C) samples with different CaO cantent has been conducted some samples contain graphite and some don’t.It is found out that the refractoriness under load of the unfired MgO-CaO-C brick is higher than that of MgO-C brick.

关 键 词：镁钙炭砖 镁炭砖 不烧砖 荷重软化温度 耐火材料
