Dushyigikiwe nitsinda ryitumanaho ryateye imbere kandi ryinzobere, dushobora gutanga ubufasha bwa tekiniki mbere yo kugurisha & nyuma yo kugurisha kubiciro bidahenze Ubushinwa Cat Bulldozer D7 D7c D7d D7e D7f Single Flange Track Roller Bottom Roller ya Dozer Undercarriage, Hamwe nurwego runini. , ubuziranenge, ibiciro byumvikana hamwe nigishushanyo mbonera, ibisubizo byacu bikoreshwa cyane muruganda nizindi nganda.
Gushyigikirwa nitsinda ryitumanaho ryateye imbere kandi ryinzobere, dushobora gutanga ubufasha bwa tekiniki mbere yo kugurisha & nyuma yo kugurisha kuriUbushinwa, Igice cyo gutwita, Ubwiza bwibintu byacu bingana nubwiza bwa OEM, kuko ibice byibanze byacu ni kimwe nabatanga OEM.Ibicuruzwa byavuzwe haruguru byatsinze impuguke zimpuguke, kandi ntidushobora kubyara ibicuruzwa bisanzwe bya OEM gusa ahubwo twemera ibicuruzwa byabigenewe.
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.
HONGDA Ibyuma byangiza:
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 bisa nkibice biri muri 70KGS.Kubera inkunga nitsinda IT ryateye imbere kandi ryinzobere, dushobora gutanga inkunga ya tekiniki kubicuruzwa mbere yo kugurisha & nyuma yo kugurisha kubiciro bihendutse Ubushinwa Injangwe Bulldozer D7 D7c D7d D7e D7f Imirongo imwe ya Flange Track Roller Hasi Roller ya Dozer Undercarriage, Hamwe nurwego runini, rwiza, ibiciro byumvikana hamwe nibishushanyo mbonera, ibisubizo byacu bikoreshwa cyane muruganda nizindi nganda.
Igiciro gihenzeUbushinwa, Igice cyo gutwita, Ubwiza bwibintu byacu bingana nubwiza bwa OEM, kuko ibice byibanze byacu ni kimwe nabatanga OEM.Ibicuruzwa byavuzwe haruguru byatsinze impuguke zimpuguke, kandi ntidushobora kubyara ibicuruzwa bisanzwe bya OEM gusa ahubwo twemera ibicuruzwa byabigenewe.
