水泥加入量对氧化铝-尖晶石质自流浇注料强度的影响

Influnce of cement addition on strength of self-flowing alumina-spinel castable

研究了氧化铝－尖晶石质自流浇注料的力争性能和显微结构。结果表明：当水泥加入量＜10％时，浇注料的强度随水泥加入量的增加而增大；当水泥加入量＞10％时，浇注料的强度无明显增加。此外，水泥加入量过大会影响浇注料的流动性。

The mechanics properties and microstructure of self-flow alumina-spinel castable have been investigated. It is indi-cated that when cennent addition is under 10%, the strength of the castable is improved as the cenment addition in-creases; and when the cenment addition is over 10%, the strength of the castable increases a little bit. The over addit-ion of cenment wtll affect the flowability of the castable.
