Refining slag has a high alkalinity and a low melting point, which we need to ensure if we want to improve the smelting effect of the product. So in order to improve the effect of refining slag, what aspects need to be done? In fact, the refining slag has a lot of excellent performance, we can be very good to play its performance. We will better use the refining slag, because the refining slag does have excellent performance, its melting point is very low, melting speed is very fast, has a strong desulfurization capacity, is very suitable for different kinds of steel desulfurization treatment. And the type of refractory has a certain influence on the refining process of LF furnace.
Refining slag has such advantages that it is more conducive to desulfurization of molten steel when using magnesia-carbon refractory. Moreover, when F furnace uses refining slag for refining treatment, the slag forming speed is fast, the electricity is stable, and the inclusion, gas and sulfur content in the steel is reduced. Want to improve the refining effect of the product, it is necessary to understand the sudden to dephoreging factors have some? In general, the use of alkaline refining slag has good air permeability, so the thickness of the slag layer can adjust the saturation of the molten steel gas in the ladle.
