Features of Aluminum Silicate Ramming Material Mass
1.On the face in contact with liquid metal there is a dense sintered layer where tightness of liquid metal is quite perfect.
2.Thermal conductivity is lower than other refractoriness so the Thermal loses are less than any other kind of refractory.
3.Good resistance to temperature change.
4.Low cost in furnace lining.
5.Short heating and sintering time through dry preparation Of masses.
6. Strong resistance to erosion.
Applications of Aluminum Silicate Ramming Material Mass
Ramming Mass mainly used for furnace lining of boiler, blast furnace, hot blast stove, heating furnace, ceramic kiln and various industrial furnaces.Applicable to all kinds of carbon steel, low manganese steel, alloy steel, alloy cast iron, high-speed tool steel and stainless steel.
Specification of Aluminum Silicate Ramming Material Mass
Aluminum-magnesia ramming material, high-alumina (or corundum) – silicon carbide – carbon ramming material, alkali refractory ramming material and zirconium mullite ramming material.
