Castable for resisting corrosion of metal ions
The invention relates to the technical field of amorphous refractory materials, and particularly discloses a castable for resisting corrosion of metal ions. The wollastonite, the barium sulfate and the magnesium aluminate spinel are jointly used as components of the mineral auxiliary material. The barium sulfate can be sintered and compounded with a mullite phase formed in the castable to generate a baryta feldspar phase, and under the synergistic effect of the magnesium aluminate spinel and the baryta feldspar phase, metal ions such as aluminum ions, calcium ions, sodium ions, magnesium ions, iron ions, ferrous ions, manganese ions, copper ions and the like are more difficult to react with the castable; therefore, the castable disclosed by the invention can fully resist corrosion of metal ions, has relatively long service life, and is suitable for being applied to a process for preparing aluminum by a melting method.
本申请涉及无定型耐火材料技术领域，具体公开了一种用于抗金属离子侵蚀的浇注料。本申请选用硅灰石、硫酸钡和镁铝尖晶石共同作为矿物辅料的组分。硫酸钡能够与浇注料中形成的莫来石相发生烧结复合，并产生钡长石相，在镁铝尖晶石与钡长石相的协同作用下，铝离子、钙离子、钠离子、镁离子、铁离子、亚铁离子、锰离子、铜离子等金属离子与浇注料反应的难度较大，因此本申请的浇注料能够充分抵抗金属离子的侵蚀，具有较长的使用寿命，适合在熔融法制铝的工艺中应用。
