1.Product details
Fireclay brick Al2O3 content is 30%-48%, SiO2 content is 50%-65%, etc. Its refractoriness is 1580-1750°C, refractoriness under load is 1250-1450 °C.
It is made from flint clay clinker and binder, through high temperature sintering. and a small number of alkali metals, alkaline earth metal oxides, etc. Mineral composition is usually mullite, quartz and glass phase. with good thermal shock resistance and strong ability to resist erosion acid slag.
2.Raw Material Selection
To ensure the quality of our raw materials, we only purchase our raw materials from our long-term trusted suppliers. With every purchase, the raw material must be passed 2 times inspection, 1 time at our supplier’s site. a second inspection on the batch after the material arrived to our factory.
