Nonmetallic inclusions are harmful to the quality of 42CrMo4 steel. Therefore, formation and removal mechanism in steel during steelmaking process is investigated by industrial trials. The characteristics specimens were analyzed scanning electron microscopy energy dispersive spectroscopy. main type molten early stage ladle furnace (LF) refining MgO-Al2O3 irregular shape. CaO begins appear middl...

Because of its superior properties, stainless steel has been widely used for many applications. Nonmetallic inclusions can influence the quality products. A set samples was to track response inclusion composition during processing a heat titanium-bearing 18% chromium steel, from deoxidation after decarburization, solidified slab. The oxide responded as expected additions deoxidizers and calcium...
