Refractory ramming mass is an unshaped refractory material. It’s applied by manual or mechanical ramming and hardens when heated at high temperatures. It’s made by mixing refractory aggregates, powders, binders and additives in proper proportions.
Its main advantages include high density, low porosity, good erosion resistance, spalling resistance and excellent thermal shock resistance. It has small volume shrinkage at high temperatures and offers long-term structural stability.
By material type, it can be classified into high-alumina, magnesia, zirconia, silicon carbide-carbon and so on. It works for different working conditions: acidic, neutral and alkaline. It is widely used in high-temperature industries such as metallurgy, non-ferrous metal smelting and building materials.
The ramming mass produced by Huaxiang Refractories is suitable for lining and repairing key parts such as intermediate frequency furnace linings, blast furnace bottoms and induction furnace linings. It features long service life and easy construction, providing professional refractory protection for the stable operation of industrial kilns and furnaces.
