Magnesia ramming material

* DD-1 & DD-2

The product uses high-quality magnesia and high-quality synthetic magnesia calcium sand as raw materials, and controls the appropriate particle size distribution to make it have better bulk density. Easy to sinter, resistant to corrosion and erosion. It can be used as the binding material for the bottom of electric furnace for dry construction.

* DD-3 & DD-4

This product uses high-quality magnesia as the main raw material, adding chemical binders to produce ceramic bonding in the hardening process. Good corrosion resistance and erosion resistance. It is applicable to the bottom of metallurgical furnace and the filling of corner joints. 5% - 7% water shall be added during construction.

* DD-6

The product uses high-quality sintered magnesia and fused magnesia as the main raw materials, with good high-temperature performance, corrosion resistance and erosion resistance. It is applicable to the vulnerable parts of metallurgical furnace bottom and tapping hole, AOD and VOD furnaces. Pay attention to human protection when using this product.

* DD-10 & DD-18

The product uses magnesia chrome ore and synthetic magnesia chrome ore as the main raw materials, adds composite additives, and selects the appropriate particle size composition. Because of the high temperature magnesia chrome spinel, the material has excellent corrosion resistance to low alkalinity slag. It is mainly used for RH furnace, VOD furnace, nonferrous metallurgy furnace, etc.
