Product Description of Rognsheng High Quaility Lining Material Zirconium Corundum Ramming Mass
Ramming mass is granule or powder shape material made from refractory raw material, usually, there are some proportion of binder, after rational gradation and tempering, loose amorphous ramming mass is produced. It is similar to dry-hardened castable, but some ramming mass doesn’t have self-setting binder, so fierce ramming should be applied during construction, that’s why it is called ramming mass.
Ramming Mass can be classified into high alumina, corundum, silica, magnesia, chromite, zirconia, carborundum plastic refractory, etc
Rongsheng Zirconium Corundum Ramming Mass is composed of fused zirconium corundum granule by oxidation method and a small amount of additives. It has the characteristic of atmospheric temperature hardening, high strength at high temperature, low thermal expansion and shrinkage, and strong resistance to glass liquid erosion. It is the ideal material for sealing layer at bottom of glass furnace molten pool.
1.High refractoriness, High refractoriness under load.
2. High density, low porosity.
3. Good slag resistance and corrosion resistance.
4. High strength and wear resistance.
5. Good resistance to flake performance.
6. Good thermal shock stability.
7. Scouring resistance.
8. Good hot strength.
Widely used in glass furnace bottom, ladle and circulating fluidized bed boilers and other fields. It is mainly used for lining various industrial furnaces such as glass furnace bottom, ladle and circulating fluidized bed boilers, blast furnace iron trenches, converters, ferroalloy electric furnaces, open hearth furnaces, intermediate frequency furnaces, power frequency furnaces, tundishes, electric furnaces, rotary kiln discharge ports, hot blast furnaces, heating furnaces, ceramic kilns, and various non ferrous metal smelting furnaces such as copper, aluminum, and steel.
