    Imininingwane Yomkhiqizo

    Omaka bomkhiqizo

    Inkampani yethu ibambe iqhaza kakhulu ebhizinisini lokuthekelisa lamashubhu ensimbi angenamthungo,China Steel Tube, i-SMLS yesiShayina, Amapayipi Ensimbi Angenamthungo, Amashubhu ensimbi angenamthungo, I-SMLS, SMLS China, Amapayipi esakhiwo se-SMLS.

    Amamodeli amaningana ayinhloko okukhiqizwa kweshubhu lensimbi engenamthungo eshisayo
    1, Amapayipi ensimbi agoqiwe ashisayo

    ibe imodeli evamile yokukhiqizwa kwamapayipi ensimbi angenamthungo. Ubuchwepheshe bokugoqa amapayipi obuningi obuqhubekayo.
    Uma kuqhathaniswa namanye amamodeli, umshini wokugaya oqhubekayo ube yinketho yokuqala emabhizinisini amakhulu okukhiqiza amashubhu ensimbi angenamthungo emhlabeni ngenxa yekhwalithi yawo ephezulu, okukhiphayo okuphezulu, ukusebenza kahle okuphezulu, nokusetshenziswa okuphansi.
    2, I-3 rolling pipe rolling mill

    kwavula inkathi entsha yobuchwepheshe obuqhubekayo bepayipi lensimbi eliginqikayo
    Kusukela ngo-2005, sekube namasethi angaphezu kuka-20 ezigayo ezingu-3 eziqhubekayo ezakhiwe futhi ezisakhiwa emhlabeni wonke. Ukwakhiwa kwalezi zigayo kudale inkathi entsha yobuchwepheshe bamapayipi ensimbi aginqikayo angu-3.
    3. Umshini wokugoqa wamapayipi ozenzakalelayo, owaziwa nangokuthi i-Plug mill
    Phakathi kwazo, izigayo ezinkulu neziphakathi nendawo eziginqikayo zamapayipi zisadlala indima ebalulekile ngemva kokuguqulwa kwezobuchwepheshe.
    4. I-Periodic pipe rolling mill, eyaziwa nangokuthi i-Pilger mill

    ilungele ukukhiqizwa kodonga oluphakathi nolugqinsi lwamapayipi ensimbi amakhulu naphakathi. Ingenye yamamodeli amadala kakhulu emhlabeni
    Ngenxa yezinga eliphansi lokukhiqiza kanye nekhwalithi ephansi yangaphandle yalesi sigayo, izindleko zayo zokukhiqiza kanye nekhwalithi yomkhiqizo kunzima ukuncintisana nezinye izigayo. Izigayo eziningi ezincane nezimaphakathi seziqediwe. Isigayo esikhulu sokugoqa amashubhu esinezinkathi ezithile sisenenzuzo ekukhiqizeni amashubhu ensimbi anobubanzi obukhulu anodonga oluwugqinsi, ikakhulukazi ukukhiqizwa kwamashubhu esiteshi samandla esiwugqinsi anobubanzi obukhulu. Izigayo ze-periodic tube rolling ziseyindlela esebenzayo, ngakho ziyagcinwa.
    5.Umshini wokugoqa wamashubhu oqondile, umshini wokugoqa we-3-roll
    Umshini wokugoqa amashubhu oqondile ubizwa nangokuthi umshini wokugoqa amashubhu we-Accu2Roll, kanti umshini wokugoqa we-3-roll ubizwa nangokuthi umshini we-Assel tube rolling. Futhi iyishubhu yensimbi engenamthungo enokunemba okuphezulu. Ukucushwa kwezinqubo zangaphambili nangemuva ngokuyisisekelo kuyafana ne-Accu2Roll tube mill ngaphandle kokuthi uhlaka lisebenzisa i-3-roll cross-rolling.
    6. Eminye imishini ye-tube rolling
    Ngaphandle kwaseShayina, ama-extruder, imishini yokugenca amapayipi anobubanzi obukhulu, kanye nemishini yokugingqika nokwandisa ama-skew enobubanzi obukhulu inentuthuko encane entsha kwamanye amazwe emhlabeni. E-China, ngenxa yentuthuko esheshayo yokukhiqizwa kwamapayipi ensimbi angenamthungo kanye nesidingo semikhiqizo ephezulu, ukwakhiwa kwalezi zigayo kuye kwenza intuthuko entsha.

    Siyakwamukela ukuvakashela inkampani yethu, ifektri lapho ibonisa imikhiqizo ehlukahlukene ezohlangabezana nokulindela kwakho. Okwamanje, kulula ukuvakashela iwebhusayithi yethu, futhi abasebenzi bethu bokuthengisa bazozama konke okusemandleni abo ukukunikeza isevisi engcono kakhulu. Sicela usithinte uma udinga ulwazi olwengeziwe. Inhloso yethu ukusiza amakhasimende ukuthi abone izinhloso zawo. Senza imizamo emikhulu ukuzuza lesi simo esiphumelelayo.

    a.Ngokungeziwe kumamaki e-Q345A ne-Q345B, insimbi kufanele iqukathe okungenani ingxenye eyodwa yezinto ezisanhlamvu ezicwengisisiwe i-Al, Nb, V, ne-Ti. Ngokwezidingo, umphakeli angakwazi ukwengeza izakhi zokusanhlamvu ezicwengisisiwe eyodwa noma ngaphezulu. Inani eliphakeme lizoba njengoba lishiwo kuthebula. Uma ihlanganiswa, i-Nb + V + Ti ayikho ngaphezu kuka-0.22%b. Kumabanga e-Q345, Q390, Q420 kanye ne-Q46O, i-Mo + Cr ayikho ngaphezu kuka-0.30%c. Uma i-Cr ne-Ni yebanga ngalinye kusetshenziswa njengezakhi ezisele, okuqukethwe kwe-Cr ne-Ni akufanele kube kukhulu kuno-0.30%; uma kudingekile ukwengeza, okuqukethwe kufanele kuhlangabezane nezidingo etafuleni noma kunqunywe umphakeli nomthengi ngokubonisana.d. Uma umphakeli engaqinisekisa ukuthi okuqukethwe yi-nitrogen kuyahlangabezana nezimfuneko ezisethebula, ukuhlaziywa kokuqukethwe kwe-nitrogen kungase kungenziwa. Uma i-Al, Nb, V, Ti nezinye izakhi ze-alloy ezine-nitrogen fixation zengezwa ensimbi, okuqukethwe kwe-nitrogen akunqunyelwe. Okuqukethwe kokulungisa i-nitrogen kufanele kucaciswe kusitifiketi sekhwalithi.e. Uma usebenzisa i-aluminium egcwele, ingqikithi yokuqukethwe kwe-aluminium Alt ≥ 0020%.
