钢包精炼炉用铝碳滑板的研制

Development of Al2O3-C Slider for Ladle Furnace

以特级高铝钒土熟料作骨料，利用电熔刚玉细粉、鳞片石墨及添加剂优化基质相组成．采用水玻璃为主及助结合剂复合结合。加入适量的防氧化剂．研制出具有高的常温、高温强度．抗热冲击性能优良．抗侵蚀和冲刷能力强的不烧铝碳滑板，满足了钢包精炼炉的需要、试验表明．试样在85℃，8h干燥是有必要的．成型压力选在200MPa左右为宜．助结合剂的加入量应小于5％。

With the aggregate-super bauxite Chamotte, using fused corundum powders. flake graphite and additives to improve the matrix phase composition, adopting composite-bihider of water glass and assistant binder, and adding a certain amount of antioxiflant. the Al2O3-C slider has been developed. It has a high strength at ambient and elevated temperature, and better resistance to thermal shock. corrosion and scouring.The test results show that it is essential to dry foe samples at 85℃ for 8h and shape at about 200MPa pressure, and add the assistant binder less than 5 %.
