Chiyambi cha njira ya square tube (yozungulira mpaka lalikulu).
Tianjin Yuantai Derun GuluJCOE Φ 1420unit akhoza linanena bungwe specifications ndi caliberΦ 406 mm to Φ 1420 mm, ndi makulidwe apamwamba a khoma la 50mm. Pambuyo kuyikidwa mu kupanga, izo zipangitsa kusiyana mu msika Tianjin wa mankhwala amenewa, amene akhoza kwambiri kufupikitsa nthawi kuyitanitsa awiri kopitilira muyeso-lalikulu, kopitilira muyeso-wokhuthala khoma dongosolo kuzungulira machubu ndi mankhwala lalikulu chubu. Chitoliro chokhala ndi mbali ziwiri chomiza arc chowotcherera chitoliro chachikulu chowongoka chimatha kugwiritsidwa ntchito mwachindunji potumiza mafuta ndi gasi.Chitoliro chachitsulo cha JCOEyakhala ikugwiritsidwa ntchito kwambiri pantchito yapadziko lonse ya "West-East Gas Transmission". Pa nthawi yomweyo, angagwiritsidwe ntchito ngatichitoliro chachitsulo chomangapomanga mapulojekiti apamwamba kwambiri achitsulo. Komanso, "kuzungulira kwa lalikulu"Njira angagwiritsidwe ntchito pokonza mu m'mimba mwake kopitilira muyeso-lalikulu, kopitilira muyeso-wandiweyani khoma zitsulo chitoliro, amene angagwiritsidwe ntchito m'munda wa malo lalikulu zosangalatsa ndi katundu makina kupanga zida.
The "kuzungulira kwa lalikulu"Chigawo paokha kupanga ndi Tianjin Yuantai Derun Gulu ali ndi mphamvu pokonza awiri awiri a 1000mm × 1000mm lalikulu chubu, 800mm × The processing mphamvu ya 1200mm amakona anayi chubu ndi pazipita khoma makulidwe a 50mm ndi wapamwamba-lalikulu awiri ndi wapamwamba wandiweyani khoma chubu yamakona anayi idaperekedwa bwino pamsika wapakhomo mpaka 900mm × 900mm × 46mm, potulutsa max 800mm × 800mm × 36mm mainchesi akulu kwambiri komanso zida zokulirapo zapakhoma zimakwaniritsa zofunikira zosiyanasiyana zaukadaulo za ogwiritsa ntchito apakhomo ndi akunja, kuphatikiza. 400mm amakona anayi chubu × 900mm × 30mm mankhwala amaimira mlingo kutsogolera "wozungulira lalikulu" luso kunyumba ndi kunja.
Nyumba yachitatu yayitali kwambiri padziko lonse lapansi - nyumba yosanja kwambiri ku Wuhan, China yokhala ndi kutalika kwa 636 metres - Wuhan Greenland Center ndi ntchito yoyimira zitsulo zapamwamba kwambiri zoperekedwa ndi Tianjin Yuantai Derun Gulu.
Pambuyo pazaka zambiri zakusintha kwazinthu, mbali yakunja ya chubu chachikulu cham'mimba mwake kopitilira muyeso-wakukulu kopitilira muyeso wamakona anayi opangidwa ndi njira ya "zozungulira-mpaka-mzere" ya Tianjin Yuantai Derun Gulu yakwanitsa kuthana ndi zolakwika zomwe zimatha kusweka panthawi yozungulira- ku-square kupinda ndondomeko ndi zovuta mu ulamuliro wa flatness wa chubu pamwamba pa "mapindikidwe" ndondomeko, amene angathe kukwaniritsa zofunikira za mfundo zapakhomo ndi zakunja kwa mankhwala ndi kasitomala wapadera luso chizindikiro kulamulira zofunika. Chogulitsacho chatamandidwa kwambiri pama projekiti akuluakulu omwe amatumizidwa ku Middle East, ku China, amathanso m'malo mwazogulitsa za "bokosi" m'mabizinesi oyambira omwe adasonkhana. Chifukwa machubu a square chubu amakhala ndi weld imodzi yokha, kukhazikika kwake kumakhala kwabwinoko kuposa zinthu za "box column" zowotcherera kuchokera ku mbale zachitsulo zokhala ndi ma weld anayi. Izi zitha kuwoneka pazofunikira zomwe Party A imaneneratu kugwiritsa ntchito "square chubu" ndikuletsa kugwiritsa ntchito "box column" pama projekiti ena ofunika akunja.
Pankhani yaukadaulo wopindika wozizira wopanga, Tianjin Yuantai Derun Gulu ali ndi zaka pafupifupi 20 kudzikundikira ndipo amatha kusintha mapaipi achitsulo opangidwa ndi mawonekedwe apadera malinga ndi zomwe kasitomala amafuna. Chithunzichi chikuwonetsa "chitoliro chachitsulo chaoctagonal" chosinthidwa ndi malo akulu osangalatsa ku China. Chifukwa cha mapangidwe apangidwe, amafunika kuzizira nthawi imodzi. Chifukwa cha zofunikira za kukula kwake ndi makulidwe a khoma la mankhwala, opanga akuluakulu ku China adafunsa za izo kwa miyezi yoposa itatu. Pomaliza, kokha Tianjin Yuantai Derun Gulu akhoza kukwaniritsa zofunika zosiyanasiyana, ndi bwino opangidwa pafupifupi matani 3000 kuti amalize ntchito zonse zoperekera ntchitoyo yekha.
Kutenga njira "yosinthidwa" yomwe ikuyang'anizana ndi msika ndi njira yotsatsira ya Tianjin Yuantai Derun Group. Pachifukwachi, Tianjin Yuantai Derun Gulu, ndi cholinga chachikulu cha "zonse lalikulu chubu mankhwala Yuantai ayenera kukhala wokhoza kutulutsa", akuumirira ndalama zoposa 50 miliyoni Yuan pachaka kafukufuku ndi chitukuko cha zida zatsopano, nkhungu zatsopano ndi zatsopano. njira. Pakali pano, izo anayambitsa wanzeru tempering zida, amene angagwiritsidwe ntchito kupanga akunja arc amakona anayi lalikulu chubu kwa galasi nsalu yotchinga khoma zomangamanga, ndipo angagwiritsidwe ntchito annealing mpumulo nkhawa kapena yotentha kupinda chubu lalikulu, Iwo kwambiri amalemeretsa processing mphamvu. ndi osiyanasiyana mankhwala kuti akhoza kupangidwa, ndipo akhoza kukumana makasitomala 'oyimitsa chimodzi zofunika kugula mapaipi structural zitsulo.
As ife tonse tikudziwa, bokosi mzati chimagwiritsidwa ntchito lalikulu zitsulo nyumba nyumba kunyumba ndi kunja, ndipo wakhala wotchuka kwa zaka zambiri kunja. Masiku ano, mayunitsi ochulukirapo omanga ndi mapangidwe amagwiritsa ntchitochubu chachikulu amakona anayim'malo mwa mzati wa bokosi. Ndi makulidwe akuchulukira akale, idzaphimba kwathunthu kugwiritsidwa ntchito kwa bokosi lanyumba posachedwa.
Pakadali pano,chubu lalikulu lalikuluimatulutsidwa mu chubu lalikulu ndi njira yomizidwa ndi arc yowotcherera ndi zida zapadera. Kuwotcherera kwa arc m'madzi ndi imodzi mwa njira zowotcherera zamakina zomwe zimakhala ndi mphamvu zambiri. Dzina lake lonse ndi kuwotcherera kwa arc, komwe kumadziwikanso kuti automatic arc welding pansi pa flux layer. The round to square chubu yopangidwa ndi njirayi ili ndi zabwino izi:
1.Kupanga kwakukulu
Kumbali imodzi, kutalika kwa waya wowotcherera kumafupikitsidwa, ndipo kachulukidwe kakali pano ndi kachulukidwe kakali pano akuchulukirachulukira, kotero kulowa kwa arc ndi kuwotcherera waya kumakula bwino kwambiri. slag, palibe kutayika kwa kutentha kwa arc, ndipo sipatter ndi yocheperako. Ngakhale kutayika kwa kutentha kwa kusungunuka kusungunuka kumachulukira, mphamvu yonse yamafuta ikuwonjezekabe kwambiri.
2.Mkulu weld khalidwe
The kuwotcherera magawo akhoza kukhala okhazikika ndi kusintha basi. Zofunikira pamlingo waukadaulo wa welder sizokwera. Kupangidwa kwa weld ndi kokhazikika ndipo mawonekedwe amakina ndi abwino.
3.Malo abwino ogwirira ntchito
Kuphatikiza pa kuchepetsa mphamvu ya ntchito yowotcherera pamanja, ilibe ma radiation arc, omwe ndi mwayi wapadera wowotcherera arc pansi pamadzi.
4.Mtengo wotsika pokonza
Nthawi zambiri, mtengo wokonza bokosi ndi wokwera mpaka 1000 mpaka 2000 yuan, pomwe mtengo wamachubu akulu amakona anayi ndi ma yuan mazana angapo, omwe ndi okwera mtengo kwambiri.
5.Otetezeka kugwiritsa ntchito
Poyerekeza ndi awiriwo, kuchuluka kwa kuwotchererachubu lamakona anayindi zochepa kwambiri kuposa za bokosi la bokosi, ndipo kuchuluka kwa kuwotcherera kumachepetsedwa kwambiri.
