High-aluminium castable material characteristics
1, good performance of high temperature resistance, high temperature environment does not fall off, high strength.
2, add alumina superfine powder after good wear resistance, good resistance to acid and alkali erosion performance.
3, high strength, resistant to material scouring, strength is 2-3 times of building bricks and blocks.
4, patented scientific formula to make the castables high temperature strength and thermal stability to further improve, and effective control of calcium oxide content, high load softening temperature, long service life, construction and other characteristics of easy to improve heat preservation, reduce heat loss, reduce the ambient operating temperature has a significant effect!
