Ductile icyuma gikoreshwa kumurongo wikurikiranya

Intangiriro Muri make:

Icyuma cyitwa Ductile, kizwi kandi nka ductile cast Iron, nodular cast fer, spherical grafite fer, spherical grafite cast fer na SG icyuma, ni ubwoko bwicyuma gikungahaye kuri grafite cyavumbuwe mu 1943 na Keith Millis.Mugihe ubwoko bwinshi bwibyuma bidafite intege nke muburemere no gucikamo ibice, ibyuma byangiza bigira ingaruka nyinshi no kurwanya umunaniro, bitewe na grafitike ya nodular.Icyuma cyangiza ntabwo ari ikintu kimwe ahubwo ni igice cyitsinda ryibikoresho bishobora kubyara ibintu byinshi binyuze mugucunga microstructure.Igisobanuro gisanzwe kiranga iri tsinda ryibikoresho nuburyo bwa grafite.Mu byuma byangiza, grafite iri muburyo bwa nodules aho kuba flake nko mubyuma.Mugihe ibice bya grafite bikarishye bitera ingingo yibanda kuri matrike yicyuma, nodules zegeranye zibuza kurema ibice, bityo bigatanga ihindagurika ryongerera imbaraga izina ryayo.

Icyuma cyitwa ductile icyuma (ADI; ni ukuvuga austenite tempered [7]) cyavumbuwe mu myaka ya za 1950 ariko kigurishwa kandi kigera ku ntsinzi nyuma yimyaka mike.Muri ADI, imiterere ya metallurgical ikoreshwa muburyo bukomeye bwo kuvura ubushyuhe.

Ibigize

Igice kinini (%) kuri ferritic ductile fer casting [8]

Ibindi bikoresho byibyuma bihindura akenshi bifite bike bya sulferi nayo.

Carbone, 3.2–3.60%

Silicon, 2.2-2,8%

Manganese, 0.1–0.2%

Magnesium, 0.03–0.04%

Fosifore, 0.005–0.04%

Amazi meza, 0.005–0.02%

Umuringa, <0,40%

Icyuma, kuringaniza

Ibintu nkumuringa cyangwa amabati birashobora kongerwaho kugirango byongerwe imbaraga kandi bitange imbaraga mugihe kimwe bigabanya guhindagurika.Kunanirwa kwangirika kwangirika kurashobora kugerwaho mugusimbuza 15-30% byicyuma mumavuta hamwe na nikel, umuringa, cyangwa chromium.

Silicon nkibintu bigize grafite irashobora gusimburwa igice na aluminiyumu kugirango irinde okiside nziza.

HONGDAIbyuma byangizaings:

Mu ntangiriro za 2021, HONGDA yubatse uruganda rushya rwo kumenyekanisha ibikoresho n'umurongo wo kubyaza umusaruro Ductile Iron.
1. Ibikoresho: QT450 # -10 na Spheroidisation irenze urwego rwa III kugirango ubone ubuziranenge bwiza bwa casting kugirango ushyigikire icyifuzo cyawe.
2. Umurongo wibyakozwe byikora kugirango ugere kumikorere ihanitse kandi nubushobozi bunini, 550T / Ukwezi, kugirango usubize ibyo ukeneye byihutirwa.
3.Ibisabwa: ibyuma byangiza ibyuma bya roller collar, bracket idakora nibindi nkibice muri 70KGS.
