What's the effect of adding dolomite to the converter?
The main component of dolomite is CaCO3 and MgCO3. Adding dolomite can increase the amount of MgO in slag, and reduce the erosion of slag to lining and the melting loss of lining.
Dolomite is cooked is the main component of calcium oxide and Magnesium Oxide, the addition of dolomite has two functions, one can improve the content of Magnesium Oxide early in the slag, reduce the erosion of brick, is conducive to improve the service life of the lining. The second is to help pre slag, magnesium in slag in the form of oxide, and other ingredients can form a low melting point compounds, so as to promote the formation of good slag in the early stage. Conducive to follow-up operations.
The lining of converter is magnesia, and the addition of mature dolomite increases the content of MgO in molten steel, thus inhibiting the diffusion of MgO in steel lining to steel water, so as to protect lining and increase slag splashing
