Refractory Brick By Henan Lite Refractory Material Co,.ltd.

We are engaged in offering excellent quality Refractory Brick to our valuable clients. Fireclay brick is made from flint clay clinker and binder,through high temperature sintering. Al2O3 content is 30%-48%, SiO2 content is 50%-65%, and a small number of alkali metals, alkaline earth metal oxides, etc. Mineral composition is usually mullite, quartz and glass phase. Its refractoriness is 1580-1750A C, refractoriness under load is 1250-1450 A C, line expansion coefficients is low, with good thermal shock resistance and strong ability to resist erosion acid slag.
1. High refractoriness, high-temperature endurable;
2. Good thermal shock resistance;
3. Good volume stability at high temperature;
4. Good corrosion resistance;
5. Good spalling resistance and wear resistance;
6. High mechanical strength;
7. High-temperature creep rate is low;
It is used for building Such as blast furnace,hot blast furnace(stove), pellet shaft furnace,hot metal ladle,steel ladle, tundish, heating furnace, soaking pit furnace,heat treatment furnace,refining furnace, reheating furnace, metal mixter furnace, cupola furnace etc thermal technology equipment.
