High-purity magnesium oxide dry-type ramming mass used in metal magnesium electrolytic cell
The invention discloses a high-purity magnesium oxide dry-type ramming mass used in a metal magnesium electrolytic cell. The high-purity magnesium oxide dry-type ramming mass is prepared by blending a composition material from high-purity electric-smelted magnesium sand and sintered seawater magnesium sand and adding a special additive agent to the composition material. The total-filling high-purity magnesium oxide dry-type ramming mass used in the metal magnesium electrolytic cell is free of forming brick seams, so that brick seams formed in masonry of smelted bricks, clay bricks and kieselguhr bricks can be avoided. Meanwhile, high-purity magnesium oxide is excellent in the performance of resisting erosion and permeation of high-temperature electrolytes. The material has certain elasticity and joint-up property since dry-type ramming is employed, so that seams and cracks generated due to expansion and shrinkage caused by temperature fluctuation in the material can be eliminated, thereby ensuring the integrality of a fireproof material at high temperature. The ramming mass is easy and quick to use and is easy to popularize.
