The smelting process of SPA-H steel
The smelting process of SPA-H steel plate
Must be after the treatment of hot metal desulphurization pretreatment, converter iron sulfur content is less than or equal to 0.010% and grilled net surface of molten iron slag smelting SPA-H steel iron requirements.
Nickel plate, copper or nickel copper alloy particles with scrap steel into converter. The carbon content of BOF steelmaking requirement is less than 0.06%, to prevent over oxidation of the molten steel. The tapping temperature control at 1640 to 1660 DEG C, before tapping first in the ladle into synthetic slag for baking.
SPA-H weathering steel using blocking slag stopper, slag stopping ball double blocking residue slag tapping, tapping process adding calcium barium, aluminum, manganese, titanium, silicon manganese, ferrosilicon, medium carbon ferrochrome, ferrophosphorus deoxidation alloying.
