Analysis of Flash Butt Welding Machine Preheating Stage

Flash butt welding ke mokhoa o sebelisoang haholo liindastering tse fapaneng. Mokhahlelo o mong oa bohlokoa ts'ebetsong ena ke karolo ea preheating, e phethang karolo ea bohlokoa ho netefatsa boleng le botšepehi ba motsoako oa weld. Sehloohong sena, re tla hlahlobisisa boemo ba preheating ea flash butt welding, ho lekola bohlokoa ba eona, lintlha tsa bohlokoa, le phello eo e nang le eona ho weld ea ho qetela.

Mokhahlelo oa preheating ka flash butt welding ke mohato oa pele moo lisebelisoa tse peli tse lokelang ho chesetsoa li kopanang 'me li kenngoa motlakase. Hona joale sena se hlahisa mocheso o matla ka har'a sebopeho sa li-workpieces, ho nolofatsa thepa le ho e lokisetsa bakeng sa ts'ebetso ea welding. Sethala sa preheating se sebeletsa merero e 'maloa ea bohlokoa:

1. Temperature Uniformity: Preheating e etsa bonnete ba hore lisebelisoa tse peli tsa mosebetsi li fihla mocheso o le mong, li khothalletsa ho futhumala ho tšoanang le ho fokotsa khatello ea mocheso nakong ea mekhahlelo e latelang ea welding.
2. Material Softening: E ​​nolofatsa sesebediswa sa mosebetsi, se etsa hore se bopehe le ho be bonolo ho se kopanya nakong ya welding.
3. Ho Tlosa Litšila: Preheating e thusa ho tlosa litšila tse holim'a metsi tse kang mafome, oli le li-oxide, tse ka 'nang tsa ama boleng ba weld.
4. Ho Fokotsa Tšebeliso ea Matla: Ka ho futhumatsa lisebelisoa tsa mosebetsi pele, matla ka kakaretso a hlokahalang bakeng sa ts'ebetso ea welding a fokotsehile, e leng se lebisang ho bolokeng litšenyehelo.

Lintlha tsa bohlokoa sethaleng sa Preheating:

1. Taolo ea Mocheso: Mocheso oa preheating ke parameter ea bohlokoa, 'me e lokela ho laoloa ka hloko ho netefatsa hore lisebelisoa tsa mosebetsi li fihla mocheso o lakatsehang bakeng sa ho cheselletsa. Mocheso o ka fapana ho itšetlehile ka thepa e cheselitsoeng.
2. Nako ea ho futhumatsa: Nako ea karolo ea preheating e bohlokoa. Nako e khuts'oane ea ho futhumatsa e ka fella ka ho nolofatsa ho sa phetheheng ha lisebelisoa, athe nako e telele haholo ea ho futhumatsa e ka lebisa tšebelisong e feteletseng ea matla.
3. Khatello: Khatello e sebelisoang nakong ea preheating sethaleng ke ea bohlokoa ho boloka kamano e nepahetseng pakeng tsa lisebelisoa tsa mosebetsi le ho netefatsa hore ho futhumala ho tšoanang.

Kameho ho Weld ea ho Qetela:

Boleng ba sethala sa preheating bo na le tšusumetso e kholo ho motsoako oa ho qetela oa weld. Li-workpieces tse futhumatsang pele hantle li lebisa melemong e latelang:

1. Li-Welds tse Matla: Ho futhumatsa ka mokhoa o ts'oanang le ho nolofatsa thepa ho fella ka li-welds tse matla le tse tšepahalang haholoanyane.
2. Mefokolo e Fokotseng: Ho tlosoa ha litšila le ho ajoa ha mocheso o tšoanang ho fokotsa monyetla oa ho ba le likoli tse kang mapetsong le li-inclusions ho weld ea ho qetela.
3. Katleho ea Matla: Ho futhumatsa hantle pele ho nako ho fokotsa tšebeliso ea matla, ho kenya letsoho ho bolokeng litšenyehelo.

Qetellong, mohato oa ho futhumatsa oa flash butt welding ke mohato oa bohlokoa o ke keng oa hlokomolohuoa. E susumetsa boleng, matla, le katleho ea ts'ebetso ea welding. Ka hona, tlhokomelo e hlokolosi ho li-parameter tsa bohlokoa le mohato o laoloang hantle oa preheating ke oa bohlokoa bakeng sa ho finyella katleho ea flash butt welds.
