Ibhloko Eyenziwe Ngentsimbi Engagqwaliyo ye-AISI 431 | Intsimbi Engagqwaliyo Enamandla Aphezulu eyi-1.4057
Inkcazo emfutshane:
IiBloko eziQhekeziweyo zeNtsimbi Engagqwaliyo ezingama-431 ziintsimbi eziqinileyo ze-martensitic eziqinileyo ezaziwa ngokuba neempawu zazo ezintle zoomatshini, ukumelana nokugqwala kakuhle, kunye nobunzima obuphezulu. Ezi bloko eziQhekeziweyo zihlala zisetyenziswa kwizixhobo zokwenza izinto ezifuna amandla kunye nokumelana nokugqwala okuphakathi, ezifana neeshafts, iimolds, izixhobo zeenqwelo moya, iindawo zepompo, kunye nezixhobo zaselwandle.
Ibhloko yentsimbi eyenziwe nge-AISI 431:
Ibhloko yentsimbi eyenziwe nge-AISI 431yimveliso yentsimbi engenasici ye-martensitic enamandla aphezulu, engamelani nokugqwala, esetyenziswa kakhulu kwizicelo ezifuna ukusebenza kakuhle koomatshini kunye nokumelana nokugqwala okuphakathi. Ngomxholo ophezulu we-chromium kunye ne-nickel, i-431 inika ukuqina okuphuculweyo, ukuqina, kunye nokumelana nokulinganisa xa kuthelekiswa namanqanaba aqhelekileyo e-martensitic afana ne-410 okanye i-420. Ezi bhloko zenziwe nge-forged zihlala zibonelelwa kwiimeko ezifakwe okanye ezicinyiweyo neziqinisiweyo (QT) kwaye zinokuphinda zenziwe ngomatshini ngokwemilinganiselo echazwe ngumthengi. Zilungele iishafts, izinto zepompo, imizimba yevalvu, kunye nezixhobo zokusebenza, iibhloko ezenziwe nge-AISI 431 zikhetho oluhle kakhulu kumashishini afana ne-aerospace, i-marine, i-chemical processing, kunye nobunjineli ngokubanzi.

Unyango lobushushu lweBhloko yoMatshini engatyiwayo engu-431
Iibhloko zoomatshini bentsimbi engagqwali ezingama-431 zihlala zilungiswa ngobushushu ukuze kufumaneke iipropati ezifanelekileyo zoomatshini. Ezona meko zixhaphakileyo yiQuenced and Tempered (QT) kunye ne-H1150. Unyango lobushushu luphucula amandla ebhloko, ukuqina kwayo, kunye nokumelana nokugqwala, okwenza ifaneleke kwi-machining echanekileyo kunye nezicelo zoxinzelelo oluphezulu. Ibhloko nganye iyacutshungulwa ukuqinisekisa ukufana kwesakhiwo, uzinzo olunemilinganiselo, kunye nobunzima obuhambelanayo kuyo yonke indawo.
1.4057 Ukugqitywa koMphezulu weBhloko eQhelekileyo
I-1.4057 Forged Stainless Steel Block, eyaziwa ngokuba yi-AISI 431, yintsimbi engagqwaliyo enamandla e-martensitic eneempawu ezintle kakhulu zoomatshini kunye nokumelana nokugqwala okuphakathi. Ibonelelwa kwimeko yokwenziwa kunye nokugqitywa kokugaya umphezulu, le bhloko inika ukuchaneka okuphuculweyo kunye nomphezulu ogudileyo, okwenza ukuba ilungele ukwenziwa komatshini we-CNC okanye ukwenziwa ngokuchanekileyo. Ukugqitywa kokugaya umphezulu kuqinisekisa ukuncipha koburhabaxa bomphezulu (ngesiqhelo i-Ra ≤ 3.2 µm), okuvumela ukulingana okungcono, ukulungelelaniswa, kunye nexesha lokugaya elincitshisiweyo kwizicelo ezibalulekileyo.
Uvavanyo lobunzima obuyi-431 square bar
Iibha zethu zesikwere zentsimbi engagqwali ezingama-431 zivavanywa ngokungqongqo ukuba rhabaxa komphezulu ukuqinisekisa ukuba ziyahlangabezana neemfuno ezichanekileyo zezicelo zoshishino ezisebenza kakuhle. Sisebenzisa iiprofilometers zomphezulu ezilinganisiweyo, silinganisa ixabiso leRa (i-Roughness Average) ngokuhambelana nemigangatho yamazwe ngamazwe efana ne-ISO 4287 kunye ne-ASME B46.1. Olu vavanyo luqinisekisa ukuba ukugqitywa komphezulu webha kufanelekile ukusetyenziswa okubalulekileyo kumashishini eenqwelo moya, olwandle, kunye nobunjineli boomatshini. Ngokumelana nokugqwala okugqwesileyo kunye namandla aphezulu okutsalwa, intsimbi engagqwali engama-431 ifanelekile kwizinto ezifuna ukuqina kunye nokuchaneka kobukhulu. Uvavanyo lokuba rhabaxa luqinisekisa ukulungela ukusebenza kwaye luphucula ukuthembeka kwemveliso kwizicelo zokusetyenziswa kokugqibela.
Ukuhamba kwemveliso yeBhloko eyi-431 Forged
Le yinkqubo eqhelekileyo yemveliso kwiibhloko zethu zentsimbi engagqwali ezingama-431:
1. Ingot → 2. Ukubumba emva kokufudumeza → 3. Ukusika → 4. Unyango lobushushu → 5. Ukugqitywa kokusila komphezulu → 6. Imveliso egqityiweyo
Ibhloko nganye iqala nge-ingot esemgangathweni ophezulu, efudunyezwayo kwaye yenziwe ngobushushu ukuze icoceke isakhiwo sayo sangaphakathi. Emva kokusikwa ngokobukhulu, ibhloko inyangwa ngobushushu ukuze ifezekise ubulukhuni nokuqina okufunekayo. Emva koko kugqitywa ngomphezulu wokugaya ukuqinisekisa ukuba ithambile kwaye ichanekile ngaphambi kokuhlolwa kokugqibela kunye nokuhanjiswa.
