Abstract
Provided is a mold flux used for casing a cast slab, the mold flux including, bases on a total wt % of thereof, 32-38 wt % of aluminum oxide (Al2O3), 8-12 wt % of strontium oxide (SrO), 8-12 wt % of potassium oxide (K2O), 8-12 wt % of fluorine (F), 5-8 wt % of boron oxide (B2O3), 3-5 wt % of lithium oxide (Li2O), and inevitable impurities. Thus, according to the mold flux, a change in components due to silicon oxide (SiO2) and calcium oxide (CaO) may be suppressed or prevented compared to those in the conventional art.
