Ama-tube mills ayizinto ezibalulekile ezokukhiqiza izimboni, ezisetshenziselwa ukukhiqiza imikhiqizo ehlukahlukene ka-tubular. Ukusebenza kwale tube mills kuthonywa kakhulu amasu we-welding aqashiwe, ikakhulukazi i-tig (tungsten inert gas) kanye ne-plasma welding. Lo mbhalo uhlola umthelela walezi zindlela ze-welding ekusebenzeni kwama-tube mill, ukugqamisa izinzuzo, ukulinganiselwa, kanye nezici ezithinta ukusebenza kwazo.
1. Ukubuka konke kwemishini yokugaya i-tube
Ama-tube mills aklanyelwe ukukhiqiza umjikelezo, isikwele, noma amashubhu amanxa amashubhu namapayipi kusuka emichimeni yensimbi ehlanganisiwe. Lo msebenzi uhilela ukukhala kwensimbi, wakubeka esakhiweni seshubhu, ukufudumeza imiphetho, bese kubhekwa nokusika ishubhu ngobude obufunayo. Ukusebenza kahle kanye nekhwalithi yomkhiqizo wokugcina kuncike ezintweni ezahlukahlukene, kufaka phakathi ukwakheka kwesigayo se-tube, impahla ebonakalayo yemichilo yensimbi, kanye namasu we-welding asetshenzisiwe.
Izingxenye ezisemqoka zeTube Mills
Izici eziphambili ze-tube mill zifaka:
- Isiteshi esingavumi: sikhipha umucu wensimbi kwikhoyili.
- Ukwakha isigaba: bobumba umucu ophansi kwishubhu.
- Isigaba se-Welding: Ukujoyina imiphetho yeshubhu usebenzisa amasu we-welding.
- Isigaba se-Sing: usayizi ishubhu kububanzi obuyisifiso.
- Isigaba sokusika: Sika ishubhu ngobude obudingekayo.
Ukubaluleka kokufudumala ekusebenzeni kwe-tube mill
I-Welding ingumsebenzi obucayi kuma-tube mills njengoba inquma ubuqotho namandla omkhiqizo wokugcina. Izinga le-Weld Joint lithinta izakhiwo zemishini ze-tube, kufaka phakathi amandla alo, i-decticity, kanye nokumelana nokugqwala. Ngakho-ke, ukukhetha izindlela ezifanele ze-welding zibalulekile ukukhiqiza amashubhu asezingeni eliphakeme ahlangabezana namazinga ezimboni.
Izinhlobo zamashubhu nezicelo zazo
I-Tube Mills ikhiqiza izinhlobo ezahlukahlukene zamashubhu, kufaka phakathi:
- Amashubhu wesakhiwo: asetshenziswa kumaphrojekthi wokwakha kanye nengqalasizinda.
- Amashubhu ezenziwe ngomshini: Kusetshenziswa ekwenzeni imishini nemishini.
- Amashubhu kawoyela negesi: esetshenziswa embonini kawoyela negesi ngokuhamba koketshezi.
- Ama-HVAC Tubes: asetshenziswa ekufudumaleni, umoya omncane, nezinhlelo zomoya.
Uhlobo ngalunye lweshubhu lunezidingo ezithile ngokuya ngezinto ezibonakalayo kanye nekhwalithi ye-welding, ethonya ekukhetheni inqubo ye-welding emisebenzini ye-tube mill.
2. Amasu we-Welding ku-Tube Mills
I-Tube Mills ngokuyinhloko isebenzisa amasu amabili we-welding: tig (tungsten inert gas) welding kanye ne-plasma welding. Zombili lezi zindlela zinezinzuzo zazo ezihlukile futhi zikhethwe ngokususelwa kwizidingo ezithile zeshubhu elikhiqizwayo.
I-Tig Welding: Izinzuzo kanye nokulinganiselwa
I-Tig Welding, eyaziwa nangokuthi igesi Tungsten Arc Welding (GTAW), isebenzisa i-electrode ye-tungsten engasebenzi i-tungsten ukukhiqiza i-weld. Indawo ye-Weld ivikelekile ekungcolisweni ngugesi we-inert, imvamisa i-argon noma i-helium.
Izinzuzo:
- Ama-Welds asezingeni eliphakeme: I-Tig Welding ikhiqiza ama-welds ahlanzekile, aqinile, futhi aqondile ane-spatter encane.
- Ukuguquguquka: Ingasetshenziswa ezinhlobonhlobo zezinto zokwakha, kufaka phakathi insimbi engenasici, i-aluminium ne-copper alloys.
- Ukulawula: Inikeza ukulawula okuhle kakhulu kokufaka kokushisa nechibi le-weld.
Ukulinganiselwa:
- Ijubane: I-Tig Welding lihamba kancane liqhathaniswa nezinye izindlela ze-welding, ezingathinta umkhiqizo we-tube mill.
- Ikhono: lidinga izinga eliphakeme lekhono nesipiliyoni kusuka ku-opharetha.
I-Plasma Welding: Izinzuzo kanye nokulinganiselwa
I-Plasma Welding ingukuhluka kwe-tig welding esebenzisa i-arc ebekiwe ukukhiqiza i-plasma yokushisa ephezulu. Le ndlela ilungele ikakhulukazi izinto ezithambile ze-welding.
Izinzuzo:
- Ijubane eliphakeme le-Welding: I-Plasma Welding ishesha ukwedlula i-tig welding, engakhuphula ukugcwala kwesigayo.
- Ukungena ekujuleni: Inikeza ukungena okujulile, okwenza kube kuhle ngezinto ezinzima.
- Ukulawulwa okuhle: kunikeza ukulawula okuhle phezu kwechibi le-weld kanye nokufakwa kokushisa.
Ukulinganiselwa:
- Izindleko zemishini: Imishini ye-Plasma Welding iyabiza kakhulu kune-Tig Welding Equipment.
- Inkimbinkimbi: Inqubo iyinkimbinkimbi kakhulu futhi idinga imishini eyinkimbinkimbi.
Izici ezithonya ukukhethwa kwecebo lokushiswa kwe-welding
Ukukhetha phakathi kwe-tig ne-plasma welding kuncike ezicini ezahlukahlukene, kufaka phakathi:
- Uhlobo lwezinto ezibonakalayo nobukhulu: Izinto ezikhudlwana zingadinga ukufudumala kwe-plasma ukuze uthole ukungena ngokujulile.
- Ikhwalithi ye-Weld edingekayo: Yekhwalithi ephezulu, ama-welds aqondile, ama-tig welding angakhethwa.
- Ijubane lokukhiqiza: Uma kudingeka ijubane eliphakeme lokukhiqiza, i-plasma welding ingaba inketho engcono.
- Ukucatshangelwa Kwezindleko: Izindleko zemishini nezindleko zokusebenza kungathonya ukukhethwa kwendlela yokufaka i-welding.
3. Umthelela we-tig ne-plasma welding ekusebenzeni kwe-tube mill
Ukusebenza kwe I-Tube Mills itholwa kakhulu ngokukhethwa kwecebo le-welding. Lesi sigaba sihlola ukuthi i-Tig ne-Plasma Welding ithinta kanjani izici ezahlukahlukene zokusebenza kwe-tube mill.
Ikhwalithi ye-Weld nokubaluleka kwayo
Izinga le-Weld Joint libalulekile ngobuqotho be-tube. Ama-welds asezingeni eliphakeme abonakala:
- Ukungabikho kwephutha: Iziphene ezinjenge-porusity, imifantu, kanye nokwenziwa ngaphansi kunganciphisa i-weld Joint.
- Ukufana: I-Welffless Weld Bead Rap kanye nosayizi uqinisekisa izakhiwo zemishini ezifanayo.
- Ukuhlanekezela okuncane
Umthelela ngejubane lokukhiqiza kanye nokusebenza kahle
Ukukhethwa kwenqubo ye-welding kungathinta kakhulu ijubane lokukhiqiza kanye nokusebenza kahle kwe-tube mill:
- I-Tig Welding, ngenkathi ikhiqiza ama-welds asezingeni eliphakeme, ihamba kancane futhi inganciphisa isivinini sokukhiqiza jikelele.
- I-Plasma Welding, ngakolunye uhlangothi, inikeza isivinini esiphakeme se-welding, yandisa ukugcwala kwesigayo se-tube.
- Ukusebenza kahle okuthuthukisiwe kungaholela emalini yokonga kanye nenzuzo ephezulu yabakhiqizi be-tube.
Ukusetshenziswa kwamandla kanye nemiphumela yezindleko
Ukusetshenziswa kwamandla kuyinto ebucayi ngezindleko zokusebenza kwe-tube mills:
- I-Tig Welding imvamisa idla amandla amaningi ngenxa yejubane layo lokushisa elihamba kancane kanye nokufakwa okuphezulu kokushisa okuphezulu.
- I-Plasma Welding, naphezu kwezindleko zayo eziphakeme, ingasebenza kahle ngamandla ngenxa yejubane layo lokufudumeza elisheshayo kanye nokufakwa okuphansi kokushisa.
- Ukunciphisa ukusetshenziswa kwamandla akugcini ngokusetshenziswa kwezindleko ezisebenza kuphela kodwa futhi kunciphisa umthelela wezemvelo wokusebenza kwe-tube mill.
Umphumela kwizakhiwo zemishini zamashubhu we-welded
Indlela yokufaka i-welding esetshenzisiwe ku-tube mills ithinta izakhiwo zemishini zamashubhu anezinwele:
- I-Tig Welding ikhiqiza ama-welds nge-microskructure enhle kanye ne-Uniform Mechanical Properties, okwenza ukuthi ilungele izinhlelo zokusebenza ezidinga amandla aphezulu kanye nekhompiyutha.
- I-Plasma Welding inikezela ngokungena ekujuleni futhi ingasetshenziselwa izinsiza ezinkulu ze-welding, kepha ingahle iholele kuma-coarser miscruction kanye nezakhiwo ezahlukahlukene ezeshintshashintshayo.
- Ukuqonda umthelela we-welding kwizakhiwo zemishini kubalulekile ukuze kuqinisekiswe ukuthi amashubhu anezinwele ahlangabezana nezincazelo namazinga adingekayo.
4. Isiphetho
Ukukhethwa kwenqubo ye-welding, kungaba yi-tig noma i-plasma, kunomthelela omkhulu ekusebenzeni kwama-tube mill. Ngenkathi i-Tig Welding inikeza ama-welds asezingeni eliphakeme kanye nokuguquguquka okuhlukahlukene, kunganciphisa isivinini sokukhiqiza futhi kukhuphule ukusetshenziswa kwamandla. Ngakolunye uhlangothi, i-plasma welding, ngakolunye uhlangothi, ihlinzeka ngesivinini esisheshayo se-welding kanye nokungena okujulile kepha kungahle kube nomphumela wezakhiwo ezishintshayo zemishini. Abakhiqizi kumele bacubungule ngokucophelela lezi zinto lapho bekhetha inqubo yokufaka i-welding ukwenza kahle ukusebenza kwezigidi zabo zeshubhu futhi bahlangabezane nezidingo zezicelo zabo ezithile.
