Development of secondary refining technologyThe secondary refining has the functions of making the temperature and composition of the molten steel uniform, adjusting the composition of the molten steel, degassing (decarburization, denitrification, dehydrogenation), deoxidation, desulfurization, deph
READ MOREDenaturation of secondary refining inclusionsThe inclusions are denatured by adding calcium-containing materials, such as CaSi. CaSi can be blown into the furnace with a spray gun, or added to the furnace in the form of a core wire. The denaturation of inclusions can be studied with the CaO-Al2O3-Ca
READ MORESecondary refining refers to the refining outside the traditional steelmaking furnace (such as open hearth, refined furnace, electric furnace). The main tasks of refining are deoxidation, desulfurization, dephosphorization, decarburization, removal of inclusions, alloying and fine-tuning of composit
