Flux |
Dunite can replace Dolomite as Flux in Blast Furnace as it contains higher MgO : SiO2 ratio |
|
Moulding Sand |
Dunite can be used as moulding sand specially in non ferrous castings for its characteristics of high fusion point, low thermal expansion and its remarkable ability to resist fracture from thermal shock. Foundrymen are exploiting Dunite also for iron, manganese and stainless steel castings. |
|
Sand Blast |
In view of sharp cutting edge of grains the faster are the results. After the operation Dunite leaves less residue than Quartz. Consumption of sand per sq.meter is much less. Recovery of Dunite is more than Quartz due to extreme hardness. |
|
Abrasives |
In Countries like Norway, France & China the use of Dunite as an abrasive is giving an encouraging result. |
|
Refractories |
Dunite can be used to make Forsterite bricks for Steel Ladle, Tundish Linning etc. It can also be used to make Tundish Spraying Mass and to manufacture Eccentric Bottom Tapping (EBT) Mass. |
