The invention provides a magnesium-manganese spinel refractory material as well as a preparation method and application thereof, and belongs to the technical field of refractory materials. The invention provides a magnesium-manganese spinel refractory material. The magnesium-manganese spinel refractory material is prepared from the following raw materials in percentage by mass: 60-85% of magnesia, 3-20% of magnesium aluminate spinel, 3-20% of manganese aluminate spinel and 2-3% of a binding agent. By controlling the content of the magnesium aluminate spinel and the manganese aluminate spinel, the manganese aluminate spinel and the magnesium aluminate spinel can form a synergistic effect, and the mechanical flexibility of the refractory material is improved. Experimental results show that the magnesium-manganese spinel refractory material provided by the invention has the porosity of 14-18%, the volume density of 2.90-3.00 g/cm < 3 >, the normal-temperature compressive strength of 50-80 MPa, the normal-temperature breaking strength of 5-10 MPa, the abrasion loss of 6-15 cm < 3 > and the elastic modulus of 18-25 GPa.
本发明提供了一种镁锰尖晶石耐火材料及其制备方法和应用，属于耐火材料技术领域。本发明提供了一种镁锰尖晶石耐火材料，由包括以下质量百分比的原料制备得到：镁砂60～85％、镁铝尖晶石3～20％、锰铝尖晶石3～20％和结合剂2～3％。本发明通过控制镁铝尖晶石和锰铝尖晶石的含量能够使得锰铝尖晶石与镁铝尖晶石形成协同作用，改善了耐火材料的机械柔性。实验结果表明，本发明提供的镁锰尖晶石耐火材料的气孔率为14～18％，体积密度为2.90～3.00g/cm3，常温耐压强度为50～80MPa，常温抗折强度为5～10MPa，磨损量为6～15cm3，弹性模量为18～25GPa。
