Calcined magnesia olive sand

Calcium magnesium olivine:

Because of the high content of CaO and Ai2O3 in raw ore, it is easy to absorb water and self-powder, so it is not suitable for refractories. It can be used as sand for steel casting with poor reusability after washing. Or as an additive for blast furnace ironmaking.

Magnesium-rich olivine:

M2S is a kind of high quality alloy steel moulding sand material and good refractory material because of its high mineral content, high hardness and very low harmful impurities affecting refractoriness. It can also be used as an additive for blast furnace ironmaking.

It can be processed by crushing.

For casting, calcined olivine is preferred. Raw meal contains free SIO 2, which produces a lot of flue gas during casting.
