Water glass bonded 2.51g/cm3 Ramming mass High strength Refractory castable for Furnace lining
Refractory ramming mass is made of refractory aggregates, binders and admixtures, etc. The refractory aggregate varieties are divided into clay, high-alumina, mullite corundum, siliceous, magnesia and silicon carbide and so on. According to the composition, and ramming method construction, so called refractory ramming mass.
Refractory ramming mass is extensively used in masonry steel furnace bottom, induction furnace work lining, smelting furnace lining, electric furnace roof light parts. Application in high-aluminum iron trench, large-scale iron furnace and other thermal equipment.
Different binders used in different ramming mass:
★High-alumina, clay ramming material commonly uses phosphoric acid, aluminum phosphate, aluminum phosphate re-binding agent.
★Magnesia and other alkaline ramming materials often use phosphates and their polymers as binders.
★In the silicon ramming material commonly uses water glass, silica gel as a binder.
★The use of asphalt tar or resin is mainly used as a binder.
