1,Description of Magnesium Dry Ramming Material for Electric Furnace
Magnesium Dry Ramming Material for Electric Furnace adopts fused high-quality magnesite, magnesia-iron spinel as main raw material, using tamping mechanical dry forming,beware of water addition ceramic bonding structure is formed in the process of use,compact,which makes the product very resistant to erosion and erosion, and has a good effect in use.
The product uses high iron and high calcium to synthesize magnesia and fused magnesia as aggregates, synthetic magnesia and fused magnesia as fine powder, with critical particle size of 5-6 mm and multi-stage ingredients.Through strong tamping construction, the density after construction is ensured and sintered into a solid whole at appropriate temperature. Generally speaking, the first life of dry ramming material can reach more than 300 stoves,by repairing the mat, the furnace can be extended to 500-600 stoves, which not only reduces the number of stops, but also reduces the consumption of refractories per ton of steel.
