Aluminum-magnesium mending material for steel ladles and preparation method thereof
The invention belongs to the technical field of refractory materials, and particularly relates to an aluminum-magnesium mending material for steel ladles and a preparation method thereof, which are characterized in that the mending material comprises the following components: 5-3mm alumina, 3-1mm alumina, 1-0mm tabular corundum and 1-0mm fused magnesite, white corundum fine powder of 120 meshes, white corundum fine powder of 325 meshes, magnesia fine powder of 180 meshes, alumina-magnesia spinel fine powder of 325 meshes, Guangxi clay fine powder of 200 meshes, alpha-Al2O3 micro powder of lessthan 5 microns, a composite binding agent, an additive accounting for 0.3-0.5% of the total weight of the raw materials, and explosion-proof fibers accounting for 0.06-0.1% of the total weight of theraw materials. The aluminum-magnesium mending material for the steel ladles has good viscosity, plasticity and smearing performance, rebound is little, the adhesion rate is larger than 95%, the use amount of the mending material for the steel ladle can be reduced, the service life of the steel ladle is effectively prolonged, the cost of refractory materials is reduced, and the production efficiency of the steel ladle is improved.
本发明属于耐火材料技术领域，具体涉及一种钢包用铝镁修补料及其制备方法，其特征在于，所述修补料包括以下各组分：5～3mm的矾土、3～1mm的矾土、1～0mm的板状刚玉、1～0mm的电熔镁砂，120目的白刚玉细粉、325目的白刚玉细粉、180目的镁砂细粉、325目的铝镁尖晶石细粉、200目的广西粘土细粉、＜5μm的α‑Al2O3微粉和复合结合剂；以及占上述原料总重量0.3～0.5％的外加剂和0.06～0.1％的防爆纤维；本发明钢包用铝镁修补料具有较好的粘性、塑性和涂抹性，反弹少，附着率＞95％，能够降低钢包修补料使用量，有效提高钢包使用寿命，降低耐火材料成本，提高钢包的生产效率。
