1·This article studies the effect of matrix component on refractoriness under load (RUL) 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。
2·Advantage: Bear the heat, the anti - decay, refractoriness under load is high. It is suitable to be used in different high temperature kiln stove.
优点：耐高温，抗腐蚀，荷重软化点高，适合在各种气氛条件下的高温炉中使用。
3·After the specimens were sintered, with the decrease of the content of mullite in matrix the bend strength decreased, but the refractoriness under load increased.
达到烧结后，试样的常温强度随基质中莫来石含量的减少逐渐降低，高温荷重软化温度逐渐升高。
4·The bend strength and the refractoriness under load of the specimen in which mullte was used as a part of coarse particle were all higher than that the specimen with mullte the coarse particle.
粗颗粒中加入一部分莫来石与粗颗粒都为莫来石的试样相比具有更高的常温强度和高温荷重软化温度。
