Saamayntaspheroidizer(nodularizerBirta lagu shubo waa laba qaybood:

1. Dhul naadir ah sida wakiilka nodulating ee lagu milmay birta dhalaalaysa waxay saameyn xooggan ku leedahay samaynta carbide.Waa element antigraphitized. Si kastaba ha ahaatee, ku darida qadar yar oo dhul dhif ah oo ku jira spheroidizer-ku salaysan magnesium ayaa si weyn u kordhin kara heerka dhalaalka ee kabka. Bir. Iska yaree; Haddii qadarka dheeriga ahi uu badan yahay, u janjeersiga birta shubka waa la wanaajin doonaa. Dhacdadan u muuqata mid iska hor imanaysa run ahaantii ma aha mid iska hor imanaysa

2, Markaspheroidizer Waxaa ku jira curiyayaasha dhulka naadir, sulfide iyo oksaydhisku aad bay u deggan yihiin, cabbirka qayb yar, way adag tahay in lagu dul sabbeeyo birta dhalaalaysa graphite nuclei.Magnesium oxide MgO waa wakiilka spheroidizing leh dhibic dhalaalaysa sare, xasilooni wanaagsan iyo milmay hoose ee birta dhalaalaysa, laakiin marka size qayb ka mid ah waa wax yar ka weyn, waxay sabeyn doonaa si ay dusha si ay u noqdaan wasakh, ama waxaa laga yaabaa in ku lug leh tuurista ka mid noqoshada slag.

Nodulizer (ReMgSiFe),waa qabatimo kor u qaadi kara samaynta garaafyada spheroidal ee qaybaha garaafka ee hababka wax soo saarka.Waxay kobcin kartaa garaafyada spheroidal waxayna kordhin kartaa tirada garaafyada spheroidal si qalabkooda farsamada loo hagaajiyo.Natiijo ahaan, ductility iyo adkaanta alaabooyinka ayaa la hagaajiyay si awooddooda iyo shaqadooda si weyn loo xoojiyo.

Dhulka naadir-culusnodulizersKu raaxayso awood xoog leh oo leh ka-hortagga hoos u dhaca, ka-hortagga qallooca iyo ka-hortagga faragelinta habka wax-soo-saarka.Magnesia waxa lagu maamulaa 0.6%.Marka la helo birta dhalaalaysa ee asalka ah iyo tignoolajiyada bislaaday ee qaan-gaadhka ah, magnesium-ka haraaga waxa loo xakamayn karaa si deggan.
