FeSiMg nodulizer yog ntxiv rau cov hlau molten (1450-1500 degree) hauv cov khoom siv hlau los hloov cov flake graphite rau hauv cov pob zeb kheej kheej kom zoo dua lub zog thiab ductility.
Txoj kev yooj yim tshaj plaws yog cov txheej txheem sandwich: tso FeSiMg lumps ntawm lub ladle hauv qab, npog nrog cov seem steel, ncuav hlau kub rau saum toj kom ua rau cov tshuaj tiv thaiv uas desulfurizes thiab spheroidizes graphite (ntxiv: 0.8-2.0% ntawm qhov hnyav). Ua raws li tam sim ntawd nrog ferrosilicon inoculation thiab ceev nrooj pouring rau hauv pwm kom xauv rau hauv nodularity ua ntej yuav ploj mus.
Txoj cai tom qab cov tshuaj tiv thaiv nodulizing (uas kav ntev li 1-3 feeb thiab feem ntau ua rau luv luv "nceb" nplaim taws los ntawm hlawv magnesium), koj yuav tsum tam sim ntawd inoculate hlau nrog ferrosilicon los yog lwm yam inoculants los kho cov graphite nodules thiab tiv thaiv kom txias los yog ploj. Cov hlau kho yog tom qab ntawd nchuav sai rau hauv pwm ua ntej cov nyhuv magnesium yuav ploj mus (feem ntau hauv 10-20 feeb). Kev tswj qhov kub thiab txias kom zoo, tsis muaj leej faj hauv cov hlau (80-90%) thiab zam qhov tsis xws luag xws li dross, slag inclusions, lossis misshapen nodules. Thaum ua tiav kom raug, FeSiMg kev kho mob hloov nkig grey hlau rau hauv cov khoom siv tawv, cov khoom siv dav siv rau cov khoom siv tsheb, cov kav dej, cua -turbine Cheebtsam, thiab cov tshuab hnyav castings.
