Kunyango lobushushu lokubamba, ngenxa yamandla amakhulu okufudumeza kunye nexesha elide lokufakelwa, ukusetyenziswa kwamandla kuyinto enkulu kuyo yonke inkqubo, ixesha elide, indlela yokusindisa amandla kubushushu obufumileyo.

Ukubizwa ngokuba "kukuchongwa kwe-zero" kukukhomba ekufuduseni, umphezulu wayo kwaye uguqule i-themering ithiyini yenkqubo yokufudumala, ukuguqula i-curting ye-austentitic, ukuchithwa kwesamente entsalela kunye ne I-homogesing ye-austetitic.Umdlalo wokuhamba kunye nokufudumeza kokuxolelwa kwenziwa phantsi kwesikhokelo sale nkqubo ye-Issoord efunekayo kwi-20% -30% ye-20% -3%, kodwa inokunciphisa isiphene se I-oxidation, i-dericalbolization, ukuSebenza kwakhona, njalo njalo, nto leyo efanelekileyo, eyenza inkqubela yomgangatho wemveliso.

Xa i-carbon yentsimbi kunye nentsimbi ye-alloy ephantsi ishushu kwi-AC1 okanye i-AC2, inkqubo ye-homoning ye-Austerides kwi-Pearlite ye-Pearlite ihamba ngokukhawuleza. Umsebenzi wokusebenza awusekho ngaphezulu kwe-100mm, ukufudumeza kwiziko lomoya, ubushushu bomphezulu kunye ne-core kufikeleleke kwinkqubo efanayo, i-AD-i-AD-phantse i-20% -25% yokucima ixesha lokufudumeza.

Inkqubo yohlalutyo lwethiyori kunye neziphumo zovavanyo zibonisa ukuba kunokwenzeka ukuba umntu angakhathali "ukufuduswa kwe-zero" ukufudumeza kwentsimbi ye-Steen. Ukufakelwa "Ukufudumeza kune-heating yesiqhelo kunokusindisa ixesha lama-50%, imali epheleleyo ye-10%, kwangaxeshanye i-Iross" i-I-Zero I-In Buysing "inyanzelise amandla okunciphisa" ukuphucula amandla.
