研究了硼酸盐和磷酸盐两个系列七种配方的玻璃防氧化剂 ,实验表明这两种玻璃防氧化剂均可降低铝镁碳砖的气孔率 ,提高铝镁碳砖的抗氧化能力及烧后的耐压强度 ,但也不同程度地降低了铝镁砖的高温荷重软化变形温度 ,其中磷酸盐玻璃优于硼酸盐玻璃 ,其高温荷重软化变形温度可达到 1 6 0 0℃以上 ,仍是可取的防氧化剂 .
Two series of seven kinds of glass anti-oxidants such as borate and phosphate were studied. Experiments show that both glass anti-oxidants can reduce the porosity of aluminum-magnesium-carbon brick and improve the oxidation resistance of aluminum-magnesium-carbon brick and burn Of the compressive strength, but also to varying degrees reduce the high temperature load softening deformation of aluminum-magnesium bricks, of which phosphate glass is superior to borate glass, the high-temperature load softening deformation temperature can reach more than 16O 0 ℃, is still Desirable antioxidant.
