Unshaped refractories for aluminum electrolytic cell

      It replaces refractory bricks and alumina masonry, reduces the temperature of the lower part of the electrolytic cell shell, reduces the deformation and damage of the cell shell, eliminates the gaps between refractory bricks, reduces the moisture brought by wet masonry of refractory bricks, prevents electrolyte leakage at the bottom and sides, has simple masonry process and is easy to operate, etc., which increases economic benefits and prolongs the life of the cell.
