APPLICATIONS:
Shi ne dace da waldi na high-ƙarfi launin toka baƙin ƙarfe da nodular simintin ƙarfe, kamar Silinda, engine block, gear akwatin, da dai sauransu ..
RUBUTAWA:
AWS A5.15 / ASME SFA5.15 ENiFe-CI
JIS Z3252 DFCNiFe
HALAYE:
AWS ENiFe-CI (Z408) shine simintin ƙarfe na ƙarfe tare da nickel baƙin ƙarfe gami da raguwa mai ƙarfi na murfin graphite.Ana iya amfani da shi a cikin AC da DC dual manufa, yana da barga arc, kuma yana da sauƙin aiki.Lantarki yana da halaye na ƙarfin ƙarfi, filastik mai kyau, ƙarancin haɓaka haɓakar layin layi da sauransu.Juriya ga baƙin ƙarfe mai launin toka ya kai na Z308, yayin da juriyar tsaga don simintin ƙarfe na nodular ya fi ENi-CI (Z308).Don simintin ƙarfe tare da phosphorus mafi girma (0.2% P), shima yana da sakamako mai kyau kuma zuwa yanke aikin yana ƙasa da Z308 da Z508 kaɗan.Ana amfani da Z408 a cikin walda na baƙin ƙarfe mai launin toka da baƙin ƙarfe na nodular don ɗaki
HANKALI:
Kafin waldawa, ana buƙatar gasa na'urorin lantarki na awa 1 tare da zafin jiki na 150 ± 10 ℃ kafin amfani.
Lokacin waldawa, yana da kyau a ɗauki ƙuƙƙarfan weld kuma kowane tsayin weld kada ya wuce 50mm.Guduma wurin walda a hankali da guduma nan da nan bayan walda domin kawar da damuwa da hana fasa.
Ana ba da shawarar shigar da ƙananan zafi.
