Study on some phenomena of slag in steelmaking process

2.1.1.1 Preparation of slag In order to study the effect of calcium fluoride and the presence of particles on slag viscosity, some slag compositions were chosen based on the phase diagrams of the Al 2 O 3-CaO-MgO-SiO 2 system [41]. These points are shown in Figure 2 and Figure 3. These slag compositions are also listed in Table 1 and Table 2.

SLAG ANALYSIS SOLUTIONS Bruker

Slag formers are either charged with the scrap or blown into the furnace. The Si and Al in the scrap are oxidized first to form SiO 2 and Al 2O 3 (fluxing oxides). As oxygen is blown into the furnace, the principal flux (FeO) is generated. The "slag balance" now starts to shift and the slag becomes more liquid.
