Alumina Ramming Mass Description
Alumina ramming mass is a monolithic refractory which uses bauxite clinker aggregate and powder as main raw material, fireclay, binder, water or other liquid as additives . During construction high alumina ramming mass is rammed by manual or mechanical methods and chemically bonded to reach the best kiln refractory properties during heating process. Ramming mass is usually used as tamping material for furnace body cooling equipment and stuffing material for masonry horizontal level making. Alumina ramming mix has stable chemical property, erosion resistance, abrasion resistance, palling resistance, thermal shock resistance and other characteristics, is universally used in metallurgy, building material industry, non-ferrous metal smelting industry, chemical industry, machinery industry and so on.
Alumina Ramming Mass Characteristics
- Excellent chemical stability, slag erosion resistance.
- High tensile strength, abrasion and palling resistance.
- High refractoriness under load.
- Thermal shock resistance, long service life.
- Superior high temperature consistency, low reheating liner change.

Alumina Ramming Mass Application
Alumina ramming mass is usually used as tamping material for furnace body cooling equipment and stuffing material for masonry horizontal level making. Alumina ramming material is also used as inner lining to prevent slag erosion in metallurgy, building material industry, non-ferrous metal smelting industry, chemical industry, machinery industry and so on. For instance, applied in furnace tapping, ladle lining, tanking lining of coreless intermediate frequency furnace, channeled induction furnace, middle and small blast furnace to melt grey cast iron, modular cast iron, malleable cast iron, etc.
