Chitoliro chakuda ndi chitoliro chachitsulo chopanda zokutira zoteteza. Chitoliro chakuda chimagwiritsidwa ntchito m'njira zosiyanasiyana m'nyumba. N'zofala kwambiri kuona chitoliro chakuda chikugwiritsidwa ntchito pa mzere wanu wa gasi wachilengedwe ndi mizere ya makina opopera. Popeza chitoliro chakuda chilibe zokutira zoteteza, chingathe kuchita dzimbiri mosavuta m'malo onyowa kapena chinyezi. Kuti chitolirocho chisachite dzimbiri kapena dzimbiri kunja, muyenera kupereka chitetezo kunja kwa chitoliro. Njira yosavuta ndiyo kuchipaka utoto.

INDE. Tili ndi mgwirizano wamphamvu ndi SINOSURE

RHS imayimira Rectangular Hollow Section, yomwe ndi chitoliro chachitsulo chamakona anayi.

Tilinso ndi chitoliro chachitsulo chokhala ndi malo ozungulira, malinga ndi muyezo: ASTM A500, EN10219, JIS G3466, GB/T6728 chitoliro chachitsulo chozizira chokhala ndi malo ozungulira komanso chozungulira.

Chitoliro chachitsulo cha ERW, chitoliro chachitsulo cha SSAW, chitoliro chachitsulo cha LSAW, chitoliro chachitsulo cha galvanized, chitoliro chachitsulo chosapanga dzimbiri, chitoliro choikamo ndi mapaipi, chigongono, chochepetsera, tee, chipewa, cholumikizira, flange, weldolet, chitoliro chachitsulo chosasunthika

Mapaipi achitsulo opangidwa ndi galvanized amagawidwa m'mapaipi achitsulo opangidwa ndi galvanized ozizira komanso mapaipi achitsulo opangidwa ndi galvanized otentha. Mapaipi opangidwa ndi galvanized nthawi zambiri amagwiritsidwa ntchito pa mapaipi amadzi, gasi, mafuta ndi mapaipi ena amadzimadzi othamanga kwambiri. Amagwiritsidwanso ntchito m'makampani opanga mafuta, makamaka mapaipi opangidwa ndi mafuta m'minda yamafuta ya m'mphepete mwa nyanja, zoziziritsira, mapaipi osinthira nthunzi ya malasha ndi mapaipi a mlatho, mapaipi othandizira migodi, ndi zina zotero.

Akuti chitoliro chachitsulo chopangidwa ndi galvanized chimagwiritsidwa ntchito popangira gasi ndi kutentha. Monga chitoliro chamadzi, dzimbiri pang'ono limapezeka patatha zaka zingapo. Sikuti limaipitsa zimbudzi zokha, komanso mabakiteriya amakula pakhoma lamkati la chitolirocho. Dzimbiri limayambitsa zitsulo zambiri m'madzi ndipo limaika pachiwopsezo thanzi la anthu.
Kuthira galvanizing mu chitoliro chachitsulo mu asidi kuti chitsukidwe, ndikukonza yankho lamadzi ndi ammonium chloride kapena zinc chloride ndi zinc chloride, ndikuzitsanulira mu groove. Chophimba cha galvaning mu chitoliro chachitsulo chotentha chimakhala chofanana, chokhala ndi kumatira kwamphamvu komanso nthawi yayitali yogwira ntchito. Matrix ya chitoliro chachitsulo chotentha ndi yankho lovuta komanso losungunuka la electroplating, kotero momwe mankhwala amachitira zimakhala ndi kapangidwe kakang'ono komanso kukana dzimbiri. Gawo la alloy limaphatikizidwa ndi gawo loyera la zinc ndi maziko a chitoliro chachitsulo, kotero limakhala ndi kukana dzimbiri kwamphamvu.
Chitoliro chozizira cha galvanizing chimapangidwa ndi electro galvanizing, ndipo pali kusiyana kwakukulu pakati pa kukana dzimbiri ndi chitoliro chotentha cha galvanizing. Pofuna kutsimikizira kuti ndi chapamwamba, opanga ambiri ovomerezeka a galvanizing sagwiritsa ntchito electro galvanizing (cold plating). Mabizinesi ang'onoang'ono osavomerezeka amenewo amagwiritsa ntchito electro galvanizing chifukwa mtengo wake ndi wotsika mtengo. Chitoliro chozizira cha galvanizing cha galvanizing chitsulo ndi chophimba. Chitoliro cha zinc chimayikidwa payokha ndi matrix ya chitsulo. Chitoliro cha zinc ndi chopyapyala, chomwe chimangolumikizidwa ndi chitoliro chachitsulo ndipo n'chosavuta kugwa. Chifukwa chake, kukana kwake dzimbiri ndi kochepa. Chifukwa chake, pa mapaipi ena obisika mwachindunji, mapaipi achitsulo achitsulo opangidwa ndi opanga wamba amagwiritsidwabe ntchito.

Kodi mungachotse bwanji chitoliro chachitsulo chopangidwa ndi dzimbiri?
Choyamba, ikani chosungunulira kunja kwa chitsulo kuti muchotse zinthu zachilengedwe. Dzimbiri lingachotsedwenso powapukuta pambuyo potsuka dzimbiri, kupewa dzimbiri, kutsuka kapena kuyika chitsulo, dzimbiri, kulowetsa zitsulo, ndi zina zotero. Galvanizing imagawidwa m'magawo awiri: thermoelectric coating ndi coating yozizira. Thermoelectric coating si yosavuta kuchita dzimbiri ndipo coating yozizira ndi yosavuta kuchita dzimbiri.

Chitoliro cha madzi oyaka moto chomwe chikugwiritsidwa ntchito panopa chimagwiritsa ntchito chitoliro cha galvanized, ndipo chitoliro chakunja cha galvanized chimagwiritsidwa ntchito pa utoto. Zikuoneka kuti chitoliro cha moto ndi galvanized. Mu kapangidwe ka chitsulo, uinjiniya wowotcherera umagwira nawo ntchito. Chifukwa chake, kugwiritsa ntchito chitoliro chachitsulo chowotcherera pafupipafupi kumatha kuletsa dzimbiri kwa nthawi yayitali.

Chisakanizo chopangidwa ndi chitsulo chimaonedwa kuti ndi chitsulo cha alloy pamene manganese ili ndi 1.65%, silicon yoposa 0.5%, mkuwa woposa 0.6%, kapena zinthu zina zochepa monga chromium, nickel, molybdenum, kapena tungsten zilipo. Mitundu yosiyanasiyana ya zinthu zosiyanasiyana ingathe kupangidwa chifukwa cha chitsulocho poika zinthuzi m'malo mwa zinthuzi.

Njira yowonjezerera kukonzanso chitsulo chosapanga dzimbiri kudzera mu kuchepetsa kuchuluka kwa kaboni

Kuchuluka kwa kaboni mu chitsulo chosapanga dzimbiri kuyenera kukhala kotsika kuposa komwe kuli mu chitsulo cha kaboni kapena chitsulo chocheperako cha alloy (monga chitsulo chokhala ndi zinthu zosakaniza pansi pa 5%). Ngakhale kuti ma uvuni amagetsi (EAF) ndi njira yachikhalidwe yosungunula ndi kuyeretsa chitsulo chosapanga dzimbiri, AOD ndi chowonjezera chotsika mtengo, chifukwa nthawi yogwirira ntchito ndi yochepa ndipo kutentha kumakhala kotsika poyerekeza ndi kupanga chitsulo cha EAF. Kuphatikiza apo, kugwiritsa ntchito AOD poyeretsa chitsulo chosapanga dzimbiri kumawonjezera kupezeka kwa EAF posungunula.

Chitsulo chosungunuka, chosakonzedwa bwino chimasamutsidwa kuchokera ku EAF kupita ku chidebe china. Chisakanizo cha argon ndi mpweya chimawombedwa kuchokera pansi pa chidebecho kudzera mu chitsulo chosungunuka. Zotsukira zimawonjezedwa ku chidebecho pamodzi ndi mpweya umenewu kuti zichotse zinyalala, pomwe mpweya umasakanikirana ndi kaboni mu chitsulo chosakonzedwa bwino kuti uchepetse kuchuluka kwa kaboni. Kupezeka kwa argon kumawonjezera mphamvu ya kaboni pa mpweya ndipo motero kumathandiza kuchotsa kaboni.

Kuzipa kwa chitsulo chomangidwa ndi njira yamagetsi yomwe imafuna kukhalapo kwa chinyezi ndi mpweya nthawi imodzi. Ngati palibe chimodzi mwa izi, dzimbiri silimachitika. Kwenikweni, chitsulo chomwe chili mu chitsulocho chimasungunuka kuti chipange dzimbiri, lomwe limatenga pafupifupi nthawi 6 kuposa kuchuluka kwa zinthu zoyambirira zomwe zimagwiritsidwa ntchito panthawiyi. Njira yonse ya dzimbiri ikuwonetsedwa pano. Kuphatikiza pa dzimbiri lonse, pali mitundu yosiyanasiyana ya dzimbiri yomwe ingachitikenso; dzimbiri la bimetallic, dzimbiri lozungulira ndi dzimbiri la m'ming'alu. Komabe, izi sizimakhala zofunikira pa ntchito yachitsulo chomangidwa. Kuthamanga komwe njira yozipa ikupita kumadalira zinthu zingapo zokhudzana ndi 'nyengo yaying'ono' yozungulira nyumbayo, makamaka nthawi ya chinyezi ndi kuchuluka kwa kuipitsidwa kwa mlengalenga. Chifukwa cha kusiyanasiyana kwa malo ozungulira mlengalenga, deta ya kuchuluka kwa dzimbiri singathe kufotokozedwa. Komabe, malo ozungulira akhoza kugawidwa m'magulu ambiri, ndipo kuchuluka kwa dzimbiri kofanana ndi chitsulo kumapereka chizindikiro chothandiza cha kuchuluka kwa dzimbiri komwe kungachitike.
