  • Tsatanetsatane wa Zamalonda

    Zolemba Zamalonda

    Kampani yathu imachita bizinesi yogulitsa kunja kwa machubu opanda zitsulo,China Steel Tube, SMLS Chinese, Mapaipi Achitsulo Opanda Msoko, Machubu achitsulo opanda msoko, SMLS, SMLS China, SMLS mapangidwe mapaipi.

    Zitsanzo zingapo zazikulu zopangira machubu otentha osasunthika osasunthika
    1, Hot adagulung'undisa zitsulo mapaipi

    kukhala chitsanzo chachikulu cha seamless zitsulo chitoliro kupanga. Mipikisano kuima mosalekeza chitoliro anagubuduza luso.
    Poyerekeza ndi zitsanzo zina, mphero mosalekeza anagubuduza wakhala kusankha woyamba padziko lonse Msokonezo zitsulo chubu kupanga mabizinesi chifukwa cha khalidwe lake lapamwamba, linanena bungwe mkulu, dzuwa kwambiri, ndi otsika mowa.
    2, 3 yokulungira mosalekeza chitoliro anagubuduza mphero

    anatsegula nyengo yatsopano ya mosalekeza kugubuduza zitsulo chitoliro luso
    Kuchokera mchaka cha 2005, pakhala pali makina opitilira 20 a 3-roll mosalekeza mphero zomwe zamangidwa ndipo zikumangidwa padziko lonse lapansi. Kumangidwa kwa mphero zogubuduzazi kwapanga nyengo yatsopano yaukadaulo wa 3-roll mosalekeza.
    3. Makina ojambulira chitoliro, omwe amadziwikanso kuti Plug mill
    Pakati pawo, zazikulu ndi sing'anga zodziwikiratu basi chitoliro anagubuduza mphero akadali mbali yofunika pambuyo luso kusintha.
    4. Periodic pipe rolling mill, yomwe imadziwikanso kuti Pilger mill

    ndi oyenera kupanga sing'anga ndi wandiweyani khoma lalikulu ndi sing'anga caliber zitsulo mipope. Ndi imodzi mwa zitsanzo zakale kwambiri padziko lapansi
    Chifukwa chakuchita bwino kwapang'onopang'ono komanso kutsika kwabwino kwakunja kwa mphero iyi, mtengo wake wopanga komanso mtundu wazinthu zimakhala zovuta kupikisana ndi mphero zina. Zambiri mwa mphero zazing'ono ndi zapakati zathetsedwa. Akuluakulu nthawi chubu anagubuduza mphero akadali ndi mwayi kupanga lalikulu m'mimba mwake wandiweyani-mipanda machubu zitsulo, makamaka kupanga lalikulu m'mimba mwake wandiweyani-khoma machubu magetsi siteshoni. Makina opangira ma chubu nthawi ndi nthawi akadali njira yabwino, kotero amasungidwa.
    5.Makina opukutira a Precision chubu, 3-roll chubu rolling machine
    Makina oyendetsa chubu olondola amatchedwanso Accu2Roll chubu rolling machine, ndipo makina atatu-roll chubu amatchedwanso Assel chubu rolling machine. Ndiwopanda chitsulo chogudubuza chubu chogudubuza cholondola kwambiri. Kukonzekera kwa njira zakutsogolo ndi zakumbuyo kumakhala kofanana ndi mphero ya chubu ya Accu2Roll kupatula kuti machira amagwiritsira ntchito 3-roll cross-rolling.
    6. Makina ena akugudubuza chubu
    Kupatula ku China, ma extruder, makina ojambulira mapaipi ozungulira m'mimba mwake, ndi makina ogubuduza ndi okulitsa okhala ndi mainchesi akulu ali ndi chitukuko chatsopano m'maiko ena padziko lapansi. Ku China, chifukwa chakukula kwachangu kwa chitoliro chopanda zitsulo komanso kufunikira kwa zinthu zapamwamba, kumanga mphero zogubuduzazi kwapanganso zatsopano.

    Takulandilani kudzayendera kampani yathu, fakitale yomwe imawonetsa zinthu zosiyanasiyana zomwe zingakwaniritse zomwe mukuyembekezera. Pakadali pano, ndikosavuta kuchezera tsamba lathu, ndipo ogulitsa athu ayesetsa kukupatsani chithandizo chabwino kwambiri. Chonde titumizireni ngati mukufuna zambiri. Cholinga chathu ndi kuthandiza makasitomala kuzindikira zolinga zawo. Tikuchita khama kwambiri kuti tikwaniritse izi.
