Magnesium ramming material is a bulk material made of electrofused magnesia as raw material, mixed with a variety of ultrafine powder additives, and electrofused cement or composite resin as binder.Ramming material chemical stability, erosion resistance, anti-wear, anti-peeling, heat shock, widely used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries!Used for melting grey cast iron, ductile cast iron, calcined cast iron, vermicular cast iron and cast iron alloy, melting carbon steel, alloy steel, high manganese steel, tool steel, heat resistant steel, stainless steel, melting aluminum and its alloy, melting copper alloy such as red copper, brass, white copper and bronze, etc.

The content of magnesium ramming material is above 84%, calcium oxide is controlled at 6%~8%, and ferric oxide is about 6%. Due to its high fire resistance, the service temperature reaches 1850~1950℃.

With the use of superfine powder technology, make the material with high CaO magnesia and ultrafine iron oxide, can fully in the process of calcining synthetic reaction, generating distribution evenly throughout the material 2 calcium ferrite, and no obvious shrinkage phenomenon in the sintering process, ensuring the quality of the material of the sintering synthesis and improve the effect of the use of the material at the same time.After being sintered at 1600℃ for 3 hours, the compressive strength of the sample can reach 40~50MPa, which basically meets the compressive strength indexes required by nickel iron smelting.Therefore, after a certain temperature (not less than 1200℃), the material has high density, high compressive strength, good erosion resistance and volume stability.

Magnesium ramming material is used in the bottom of the hot nickel iron furnace. Magnesium ramming material has good heat preservation and insulation property, which can reduce heat loss, improve furnace temperature, shorten smelting time and reduce smelting power consumption.The compactness of the forged furnace lining is good, which solves the local leakage phenomenon caused by the non-compactness of the formed magnesia brick masonry furnace lining.

The use of magnesia ramming material to build the nickel-iron furnace has obviously improved the lining life cycle, reduced the consumption of refractory materials, and replaced the shaped materials with amorphous materials, which is over the water.
