Introduction of heat resistant fire bricks:
heat resistant fire 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 1580-1750°C, refractoriness under load is 1250-1450 °C, line expansion coefficients is low, with good thermal shock resistance and strong ability to resist erosion acid slag.
Feature of heat resistant fire bricks:
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;
