直接结合镁铬砖

1

与直接结合镁铬砖相比，镁铁铝尖晶石砖在热震稳定性方面更优于直接结合镁铬砖，而在粘挂窑皮性能方面与其相近。

Compared with the direct-bonded magnesia-chromite brick , the magnesia-hercynite brick has the superior thermal shock resistance and the similar adhesive strength ( coatability ) .

降低砖的气孔率，提高砖的抗热震可有效减少直接结合镁铬砖的损毁。

And therefore it is an important measure to reduce the damage on the direct bonded magnesia-chrome bricks to lower the porosity and promote the thermal shock resistance of the bricks .
