magnesia zirconia brick for regenerative chamber of glass kiln

Features

♦Alkali resistance

♦Slag resistance

♦Stripping resistance

♦High temperature resistance

Product Introduction

Magnesia-zirconia bricks use high-purity fused magnesia and synthetic magnesia-zirconium sand as raw materials.
After high-pressure molding and high-temperature firing, they have excellent corrosion resistance to alkali metals, oxides and sulfides.
The product is made of fused magnesia sand and zirconium sand and their alkaline materials.
The product has a high density (bulk density) greater than 3.08 g/cm3).
It also resists alkaline corrosive atmosphere and alkaline slag corrosion and is widely used in glass melting furnaces, regenerators, cement kilns, steelmaking electric furnaces and non-ferrous metal smelting.

Application:

Magnesia-zirconia bricks are used in the regenerator of glass kilns.
