FURNACES AND REFRACTORIES Modern Eq

201994 Melting point Pure substances melt instantly at a specific temperature Most refractory materials consist of particles bonded together that have high melting temperatures At high temperatures these particles melt and form slag The melting point of the refractory is the temperature at which a test pyramid cone fails to support its own weight

Calcined Aluminas Almatis

Calcined aluminas have a particle size similar to ground mineral aggregates and can therefore easily replace aggregates with lower purity By increasing the overall alumina content of the mixes and improving their particle packing through the addition of fine alumina the refractoriness and mechanical properties such as hot modulus of rupture and abrasion resistance are improved
