Because the synthetic slag is a strong reducibility, it itself has a strong ability to deoxidize, in (Fe-Si Si-Mn) with the cooperation, can effectively remove the oxygen in the steel, and this slag can be very good adsorption of solid deoxidized products floating together. In addition, because the synthetic slag is strongly alkaline slag, deoxygenation and desulfurization, can be completed in a few minutes in the furnace diffusion deoxygenation needs dozens of minutes to complete the task, so as to achieve the purpose of rapid deoxygenation and sulfur.
1. The purity of the pre-melting refining slag is high, the chemical composition is uniform, the phase is stable, the melting point is low, the slag forming speed is fast, and the refining time can be greatly shortened;
2. Fluorine or a small amount of fluorine in the pre-melting refining slag can reduce lining erosion and effectively reduce the pollution of fluorine to the environment;
3. The lower the melting temperature of the premelted refining slag, the higher the superheat, the better the fluidity and the faster the desulfurization reaction.
Sintered refined slag has more advantages than premelted refined slag
1, low melting point, fast melting speed, shorten the refining time, reduce refining power consumption.
2, good fluidity, desulfurization and removal of inclusion capacity is strong.
3, no flame in use, small dust, good performance.
4, no water absorption, no powder, storage and transportation process will not deteriorate.
5. The submerged arc effect is good, which reduces the burning corrosion of the arc to the furnace community and improves the age of the package.
Through the above comparison, it can be seen that no matter from the time or from the use efficiency, the pre-melting type of refining slag is much better than the sintering type of refining slag, in the long run, can bring considerable economic benefits for enterprises
