On the basis of the traditional ratio, the high aluminum castable adjusts the particle gradation, adds different admixtures, reduces the cement dosage, improves the performance, increases the medium temperature strength and the softening temperature under load, reduces the thermal conductivity coefficient, and has good thermal stability. RS high alumina castable has the characteristics of high aluminum castable, such as anti-permeability, anti-erosion, anti-impact, anti-wear, good mechanical performance, strong overall structure of furnace body, better air tightness than brick furnace, longer furnace life, saving repair cost and remarkable economic benefit.
This series of refractory castable has high mechanical strength, good thermal shock resistance, abrasion resistance and other properties, with good high temperature performance, high resistance, wide temperature, no shrinkage, wear resistance and other properties. RS high alumina castable mainly used as boiler, blast furnace hot blast furnace, heating furnace, ceramic kiln and other kiln lining. It is widely used in hardware, smelting, chemical industry, non-ferrous metal and other industries, especially in iron and steel industry. It is important to be used in front of rotary kiln mouth, disintegrating furnace, kiln hood and other parts.
High alumina castable is high alumina clinker as the main raw material, many particles and grade filling each other to form a compact structure, adding high alumina refractory cement binder, shrinkage inhibitor, dispersant, coagulant and other admixtures configuration of unshaped refractory castable. (high alumina aggregate 65-70%, high alumina cement 7-10%, silica dust and oxide 5-8%, bauxite fine powder 15-24%, water reducer 0.2%, add some retarders or coagulants according to construction requirements)
RS high alumina castable has low water consumption, usually 6-7% of the refractory castable component, and therefore has high density and low porosity; It has good volume stability at high temperature. Although it is a non-burning refractory, its volume decreases after drying and calcination. It not only has high curing strength at room temperature, but also does not reduce the strength after being treated at medium temperature. The strength value is 3-5 times that of traditional refractory castable. The cement content is low and the calcium content in castable is only 1/4 to 1/3 of the traditional refractory castable. As a result, the number of low melt phases in high alumina castable is reduced and the high temperature function can be significantly improved.
High alumina refractory castable products are easy to store, transport and use. It has the advantages of anti-permeability, anti- erosion, anti-impact, anti-wear and good performance, strong overall structure of furnace body, better air tightness than brick furnace, longer furnace life, saving repair cost, remarkable economic benefits and so on.
