| ?Excellent firebrick for English fireplace 1.ISO:9002; 2.Size:230x114x30mm; 3.High resistance on fire; 4.Unusual shape.
The harsh working environment of glass furnace requires?low porosity fireclay brick?of strong capability of both chemical and mechanical erosion. The main chemical components of fire clay bricks are: 30%-48% alumina, 50%-60% silica and some alkali metals, alkali earth metal oxides, etc. Mineral composition is usually mullite, quartz and glass phase; Its refractoriness is 1580°C -1780°C and refractoriness under load is 1250°C-1450°C. Low line expansion coefficients, good thermal stock resistance and strong ability to resist erosion of acid slag. |
