Temperature and sulfur content of the original molten iron

Principles for the production of spheroidizing agents - temperature and sulfur content of the original molten iron
High temperature and low sulfur iron liquid, low magnesium and low rare earth nodularizing agent is selected. For electric furnace molten iron at 1460~1520 ℃, 0.02%~0.04%, FeSiMg8RE3 and FeSiMg7RE2 can be selected; ≤ 0.02%, available FeSiMg6RE2.
