Magnesium-calcium-iron dry ramming mass material is a dry ramming refractory material mainly composed of CaO, MgO, and Fe2Ο3, and generally contains a small amount of Al2Ο3 και SiO2. It is made through high-temperature sintering and dry ramming. It has high strength, acid slag resistance, and service temperature, and is widely used in heat preservation and fire-resistant protection of various high-temperature equipment.

Magnesium calcium iron dry ramming mass

What is dry ramming mass?

Dry ramming mass is a kind of amorphous refractory material, which adopts a vibration method without adding water or liquid binder. Under the action of vibration, the material can form a dense and uniform whole, and the strength will be generated by the thermosetting binder or ceramic sintering agent when heated. The dry vibrating material is composed of refractory aggregate, powder, sintering agent, και πρόσμιξη.

Magnesium-calcium-iron ramming material production process

Mix natural magnesite, dolomite, lightly burnt magnesia, or other raw materials containing calcium oxide and raw materials containing ferric oxide in a certain proportion, after fine grinding, ball pressing, and high temperature in a shaft kiln or tunnel kiln calcined.
