RAMMING MASS
Introduce
An amorphous refractory constructed by pounding (manual or mechanical) and hardened by heating above normal temperature. By a certain grade of refractory aggregate, powder, binder, admixture and water or other liquid after mixing. According to the material classification of high aluminum, clay, magnesium, dolomite, zirconium and silicon carbide - carbon refractory rattle material.

Application
Rattle material to silicon carbide, graphite, electric calcined anthracite as raw materials, mixed with a variety of ultra-fine powder additives, electric melt cement or composite resin as binder made of bulk material body. Used to fill the gap between furnace cooling equipment and masonry or the filler for masonry screwing. The ramming material has good chemical stability, scour resistance, wear resistance, peeling resistance, heat shock resistance, widely used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries.
Acid, neutral and alkaline rammings are widely used in coreless intermediate frequency furnace and core induction furnace. As the rammings of intermediate frequency furnace, they are used to melt gray cast iron, ductile iron, calcined cast iron, vermiculite 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 alloys, melting copper, brass, white copper and bronze and other copper alloys.
Advantage
Electric furnace bottom magnesium pounder material through the use of steel mills, confirmed its superior performance, specifically reflected in the following aspects:
1.Good sintering performance, rapid sintering and the formation of a certain strength and thickness of the sintered layer under the guarantee of sintering temperature, enough to resist the mechanical impact of the charge.
2. Suitable expansion performance, its expansion and contraction will not produce local excessive cracks to reduce the invasion of molten steel and steel slag, and will not cause local floating because of the shrinkage of the cracks, to ensure that the furnace can work continuously.
3. The larger natural packing density and sintered density can not only avoid the uneven density caused by construction and sintering, but also have higher resistance to infiltration and erosion of molten steel and steel slag.
4. Strong resistance to molten steel and steel slag erosion, low corrosion rate, uniform corrosion, long service life.
5. The hot surface of the bottom of the furnace has strong affinity with the new bottom ramming material, which can ensure the repair effect.
