Category:  Fused Cast Refractories

Application:  Glass industry

Item Code:  A1301

What is Low exudation electrofused brick?

Low exudation electrofused brick is a name primarily used by Chinese refractory suppliers compared to other ordinary types of fused cast refractories. The main chemicals in the brick are Alunima Zirconia-Silica (Al2O3, ZrO2, SiO2) and a low silicate phase of about 14%. It is recommended for the refractory solution in high-end glass furnaces.

Features of Low exudation electrofused brick

The low glass phase of the brick is achieved by introducing a low content of Na2O. Compared to traditional fused cast bricks, the low-glass-phase fused brick greatly improves the corrosion resistance, and the low exudation effectively minimizes the leakage pollution to the glass.

Advantages of Low exudation electrofused brick

Extremely low exudation

Extreme resistance to alkali vapor erosion

Extreme anti-scattering, material capacity, and creep resistance of glass raw materials

Application of Low exudation electrofused brick

The low exudation electrofused brick is mainly applied to the crown, superstructure, and doghouse arch of high-end glass furnaces, which require high resistance to high temperatures and low exudation of the glass phase.
