Due to high MgO, the advantage is that can also avoid with-in-furnace decomposition burning so as to save much energy, and improve the rate of slag in steel industry. Mgo is mineral with High melting point(2800℃), the improvement of Mgo content will increase the slag viscosity and refractoriness.

Role of MgO and Its Different Minerals on Properties

2015-10-31 The number of pores and the total pore area appears higher in 1.2 % MgO added pellet than that of 0.9 %. This is because, at lower MgO, the slag has lower melting point and its fluidity is better than the slag with higher MgO in pellet. Due to this, the lower MgO containing slag fills the pores between adjacent hematite grains.

A new fluxed pellet for use in iron-making is obtained by mixing and indurating about 1 to about 20%, by weight of the pellet, of ground melt shop slag fines with similarly ground iron ore concentrate, so as to achieve particular ranges of silica content, CaO/SiO 2 ratio, and MgO content. The melt shop slag fines have been considered a waste material, but contain significant slag and metal values.

However, RDI is an important factor for a pellet to consider it as good quality. While, in pure MgO fluxed pellet, RDI is as low as 7.5% for 0.9% MgO level in pellet, the waste magnesite brick fluxed and olivine fluxed pellets shows 28.8% and 17%, respectively. RI for olivine pellet decreases drastically due to the high amount of slag bond ...

DEVELOPMENT OF BLAST FURNACE SLAG PROPERTIES

2018-9-8 The olivine pellet is lower in gangue (and higher in MgO) compared to the acid pellet. Hence the opportunity was there to reduce the slag volume. But again, as when changing over from sinter to acid pellet in 1978, it was thought that the slag volume should not be reduced for the sake of a stable furnace operation.

Slag Conditioner - ISM, Inc.

In use, in an EAF, the slag conditioner may provide 0.5-4% excess MgO to the slag primarily as periclase. For example, a typical calcium silicate slag accounts for about 10% of the tap steel weight, which is 10 net tons of slag or 20,000 pounds of slag per 100 net tons of steel. The MgO required to saturate the slag depends on the CaO:SiO 2.
