Ubucukuzi bwa Daewoo Doosan UR190E921 Doosan 225 Isoko
Komisiyo yacu igomba kuba guha abakiriya bacu n'abaguzi ibicuruzwa byiza byo mu rwego rwo hejuru kandi bikurura ibicuruzwa bigendanwa bya DaewooIbice byo gucukura Doosan UR190E921 Doosan 225, Iterambere ridashira no guharanira kubura 0% ni politiki zacu ebyiri zingenzi.Niba ukeneye ikintu icyo ari cyo cyose, ntuzigere ushidikanya kutumenyesha.
Komisiyo yacu igomba kuba guha abakiriya bacu n'abaguzi ibikoresho byiza byo mu rwego rwo hejuru kandi bikurura ibicuruzwa bigendanwaIbice bya Daewoo, Doosan 225, Ibice byo gucukura Doosan, Ibice byo munsi, UR190E921, "Ubwiza, Serivisi nziza" burigihe ni amahame yacu na credo.Dufata ibishoboka byose kugirango tugenzure ubuziranenge, ipaki, ibirango nibindi kandi QC yacu izagenzura buri kantu kose mugihe cyo gukora na mbere yo koherezwa.Twiteguye gushiraho umubano muremure mubucuruzi bashaka ibicuruzwa byiza na serivisi nziza.Twashyizeho umuyoboro mugari wo kugurisha mu bihugu by’Uburayi, Amajyaruguru ya Amerika, Amajyepfo ya Amerika, Uburasirazuba bwo hagati, Afurika, ibihugu bya Aziya y’iburasirazuba. Nyamuneka twandikire nonaha, uzasangamo uburambe bwumwuga kandi amanota meza azagira uruhare mubucuruzi bwawe.
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%

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 byuma byuma bya roller, bracket idakora nibindi nkibice bingana muri 70KGS.Tufite urutonde rwuzuye rwamasoko hamwe nibice bya spocket mububiko kandi turaboneka kubohereza vuba kugirango bikwiranye na moteri, moteri ntoya, imashini, imashini, imashini. hamwe nizindi mashini zikurikiranwa.
MZ amasoko yacu akozwe mubyuma byujuje ubuziranenge hamwe na menyo yo hanze yinyo yinjiza yimbitse kugirango ikomeze igihe kirekire kandi ibice byahimbwe kandi bikomye cyane kugirango ubuzima burebure.
Hamagara US hanyuma uvugane ninzobere za spock kubijyanye no gutumiza.
