Kukana dzimbiri kwa kanasonkhezereka zitsulo chitoliro ku China

Chifukwa otentha-kuviika kanasonkhezereka zitsulo chitoliro ndi otentha-kuviika kanasonkhezereka, kuchuluka kanasonkhezereka ndi mkulu kwambiri. Wapakati makulidwe a malata wosanjikiza ndi oposa 65 microns, ndi kukana dzimbiri ndi osiyana kwambiri ndi otentha-kuviika kanasonkhezereka chitoliro. Opanga malata okhazikika amaloledwa kugwiritsa ntchito mapaipi ozizira ozizira ngati mapaipi amadzi ndi gasi. The kanasonkhezereka wosanjikiza ozizira kanasonkhezereka zitsulo chitoliro ndi electroplating wosanjikiza, ndi wosanjikiza nthaka wosiyana ndi zitsulo chitoliro gawo lapansi. Zinc wosanjikiza ndi woonda, ndipo zinki wosanjikiza amangomangiriridwa ku matrix achitsulo chitoliro, chomwe ndi chosavuta kugwa. Chifukwa chake, kukana kwake kwa dzimbiri ndikochepa. M'nyumba zatsopano, ndizoletsedwa kugwiritsa ntchito mapaipi achitsulo ozizira ngati mipope yachitsulo. Pambuyo pickling, API zitsulo zitsulo mapaipi kutsukidwa mu ammonium kolorayidi kapena zinki kolorayidi amadzimadzi njira kapena ammonium kolorayidi ndi zinki kloridi wosakaniza amadzimadzi yankho thanki. Pofuna kuonetsetsa kuti zabwino, electro galvanizing (kuzizira kozizira) nthawi zambiri sagwiritsidwa ntchito. Mabizinesi ang'onoang'ono okha omwe ali ndi zida zazing'ono komanso zakale amagwiritsa ntchito electro galvanizing, ndithudi, mtengo wawo ndi wotsika mtengo. Unduna wa zomanga wathetsa mwalamulo chitoliro chozizira chamalata chakumbuyo, chomwe sichikhala ndi malata amagetsi mtsogolomo. Ndiko kupanga chitsulo chosungunula kuti chigwirizane ndi matrix achitsulo kuti apange aloyi wosanjikiza, kuti agwirizane ndi matrix ndi zokutira. Hot dip galvanizing ndi pickle zitsulo chitoliro choyamba, kuti achotse okusayidi chitsulo pamwamba pa chitoliro zitsulo, ndiyeno kutumiza kwa otentha divi galvanizing thanki. Hot dip galvanizing ali ndi ubwino wokutira yunifolomu, kumamatira mwamphamvu komanso moyo wautali wautumiki. 1. Sing'anga mbale wagawo: izo makamaka umabala mbale lonse ndi wandiweyani kupanga longitudinal kumizidwa arc welded mapaipi. The longitudinal submerged arc welded mapaipi ndi khalidwe lodalirika ndipo chimagwiritsidwa ntchito mu mzere waukulu wa mafuta ndi mpweya kufala mkulu-anzanu.

Steckel Mill:Chigayo cha Steckel chimaphatikizapo mphero yobwerezabwereza komanso 4-high kubwereza mphero yomaliza. Zigayo ziwiri zotentha za koyilo zimayikidwa pamizere yolumikizira mbali zonse za mphero yomaliza. The linanena bungwe wodzigudubuza tebulo zambiri zikuphatikizapo laminar kuzirala dongosolo ndi coiling siteshoni. Pa mphero ya steckel, mbiri ya thermomechanical ya kutalika konse kwa zitsulo zosapanga dzimbiri zosapanga dzimbiri zokhotakhota zitoliro zimasintha kwambiri, makamaka popanga zopangira zitsulo zosapanga dzimbiri zosapanga dzimbiri, zomwe zidzakhudza kwambiri digiri ya recrystallization, kukula kwambewu ndi mvula pakumaliza. mphero, ndi kubweretsa kusintha kwambiri mu microstructure yomaliza ndi katundu wa utali wonse wa zosapanga dzimbiri zitsulo zopondaponda chigongono chitoliro zovekera

Semi continuous mill:kuphatikiza 1 Steckel mphero ndi 5 zomaliza. Pa mphero yosalekeza, kugudubuzika kwa zitoliro zowotchera pomaliza kumakhala kosasintha kuchokera mbali imodzi kupita ku ina. Nthawi pakati pa zidutsa pa mphero yomaliza nthawi zambiri imakhala yosakwana 3S.

CSP mosalekeza kuponya ndi kugudubuza:kwa chitsulo chochepa cha carbon manganese chokhala ndi niobium, vanadium ndi titanium composite Microalloying pa chingwe chopangira CSP, kugudubuzika koyenera, kuzizira koyendetsedwa ndi njira zopiringa zimatha kuwonetsetsa kuti makina ndi mawonekedwe a microstructure wa zoyikira zitoliro zikukwaniritsa zofunikira zaukadaulo wamakono a X60 chitsulo chosapanga dzimbiri chopondapo chigongono ndi kachitidwe ka chitukuko cha zitsulo zosapanga dzimbiri zosapanga dzimbiri zomata zitoliro za chigongono. China CSP mosalekeza kuponyera ndi anagubuduza kupanga mzere kupanga X60 zosapanga dzimbiri kuponda chigongono zovekera, pamene ena opanga CSP mu United States ndi kunja apanga ndi kupanga apamwamba kalasi zosapanga dzimbiri masitampu zovekera X60, X65 ndipo ngakhale X70. Zomwe zimapangidwira ndikuti pali tsankho lapakati pakuponya kosalekeza kocheperako. Kuthetsa tsankho lapakati pakuponya mosalekeza zitsulo zopyapyala ndi chitoliro chopanda chitsulo chosapanga dzimbiri ndiye vuto lalikulu laukadaulo kuti mupititse patsogolo luso la zomangira zitsulo zosapanga dzimbiri. Ma mbale omwe amagwiritsidwa ntchito popondaponda chitsulo chosapanga dzimbiri amagwiritsidwa ntchito makamaka A3 ndi 16Mn opangidwa ndi Angang ndi opanga ena m'ma 1960 ndi 1970. Ndi kuwonjezeka kwa chitoliro m'mimba mwake ndi kuthamanga kufala, mphamvu ya chitoliro choyenerera mbale sangathe kukwaniritsa zofunika. Pambuyo pa zaka za m'ma 1980, mafakitale onse a petroleum welded mapaipi anayamba kugwiritsa ntchito mbale zazitsulo zopangidwa motsatira miyezo ya American API. Pa nthawi imeneyo, chifukwa cha umisiri mwana wa zoweta zosapanga dzimbiri zosapanga dzimbiri opanga chigongono mbale mbale, kunja mbale ankagwiritsidwa ntchito.
