Product Description
High Quality Mullite Refractory Ramming Mix For Blast Furnace
Description:
Mullite is a series of aluminum silicate minerals collectively, the minerals scarce. Mullite is an aluminum silicate minerals at high temperatures generated, it will form artificial heating aluminum silicate mullite. Natural mullite crystals and needles are radially elongated clusters. Mullite quarry is used to produce high temperature refractory material.
Fused mullite is widely used in:
1. Low creep-rupture bricks for the hot-air stove
2. Melting-iron groove or torpedo car
3. High-temperature industrial kiln
4. Glass melting furnace
5.Shed planks
