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

PAPERS

refractory castable described in Tab 1 The simulation of the castable behavior dur ing the thermogravimetric analysis TGA was carried out by a 3Dmesh with 33920 elements and a time step of 30 s The boundary conditions used were the mass convection and the radiation heating with a source temperature equal to the furnace

Standard Dense Castables Highest Quality Products

Firebrick based dense hydraulically bonded refractory castable for general purpose use at temperatures up to 1400°C Examples of Appliions Used in kiln car bases the so called ‘brick arch’ in boilers and as a protection for floors and walls where high temperature processes are being carried out

Castable Refractory

Castable refractories are easy to mix easy to use and reasonably priced Choosing to cast a floor or an arch rather than cutting and mortaring brick gives you a monolithic piece that is joint and crack free therefore eliminating heat loss and seepage of salt soda and ash Defining the Terms Refractory—Resistant to high temperatures
