Fused Rebonded Magnesia-Titanium Brick
Classification:
Product Introduction
Product Details
Fused rebonded magnesia-titanium brick is manufactured using fused magnesia-titanium spinel and fused magnesia as main raw materials. Based on directly bonded magnesia-titanium brick, it is produced by adding special components such as high-temperature composite materials and toughening materials, followed by high-pressure forming and high-temperature sintering. It is a high-grade product with exceptionally excellent high-temperature performance and corrosion resistance.
It is suitable for the upper part of the regenerator checker in glass furnaces and other parts with high requirements for corrosion resistance.
