Khoele e Chesang e Phuthoang
Koili e phutholohang ka mocheso ke thepa ea motheo indastering ea tšepe. E entsoe ka mokhoa oa ho phutholla mocheso o phahameng 'me e na le litšobotsi tsa litšenyehelo tse tlase, matla a phahameng, le ts'ebetso e ntle ea ts'ebetso. E sebelisoa haholo kahong, mechining, likoloing, kahong ea likepe le masimong a mang.
Tlhaloso ea motheo
Khoele e phutholohileng e chesang (HRC) e bolela lihlahisoa tsa tšepe tse phutholohang ka ho tsoelang pele ka holim'a mocheso oa recrystallization (hangata >900°C) ke li-billet (tse kang li-slab kapa li-billet) 'me qetellong li kobehile.
Phapang ho tloha ho coil e phutholohileng e batang: Coil e phutholohileng e chesang ha e phutholohile e batang, bokaholimo bo makukuno, ho nepahala ha litekanyo ho tlase, empa matla a phahame 'me ductility e ntle, e leng se loketseng tlhahiso ea likarolo tsa meaho.
Likarolo tse ka sehloohong
| Litšobotsi | Khoele e phuthoang e chesang | Koili e phutholohileng e batang |
| Ts'ebetso ea tlhahiso | Ho phethoha ha mocheso o phahameng (>900°C) | Ho phutholla mocheso o tloaelehileng (ts'ebetso e batang) |
| Boleng ba bokaholimo | Sekala sa oxide, se bataletseng | Boreleli, ho nepahala ho phahameng |
| Matla | Botenya bo tlase (empa bo tiile hantle) | Ho phahama (ho thatafatsa mosebetsi) |
| Litšenyehelo | Tlase | Holimo |
| Likopo | Likarolo tsa meaho, liphaephe, liforeimi tsa likoloi | Likarolo tse nepahetseng, lisebelisoa tsa lapeng, liphanele tsa likoloi |
3. Ts'ebetso ea tlhahiso
Ho futhumatsa: Sepekere sa tšepe se futhumatsoa ho fihlela ho 1100 ~ 1250°C ho se nolofatsa.
Ho phutholla ka thata: Ho bopeha pele ka lelwala le nang le kgatello e phahameng.
Ho qeta ho phutholla: Laola botenya ho ya ka boholo ba sepheo (jwalo ka 1.2 ~ 20mm).
Ho kobeha: Ka mora ho pitikisa, e pitikiswa ka hara khoele ya tshepe (hangata e bophara ba ka ntle ba dimithara tse 1 ~ 2).
Ho Pholisa: Ho pholisa ka tlhaho kapa ho pholisa ho laoloang (joalo ka ts'ebetso ea TMCP).
Litlhaloso tse tloaelehileng
Botenya: 1.2 ~ 25mm (e tloaelehileng 2.0 ~ 6.0mm).
Bophara: 600~2200mm (e tloaelehileng 1250mm, 1500mm).
Thepa: Q235B (tšepe e se nang khabone), SS400 (tekanyetso ea Sejapane), A36 (tekanyetso ea Amerika), S355JR (tekanyetso ea Europe).
Thepa ea mechini: matla a ho thapolla 300~500MPa, matla a tlhahiso 200~400MPa.
Libaka tse ka sehloohong tsa kopo
Indasteri ea kaho: H-beam, sebopeho sa tšepe, borokho, tšepe bareng.
Tlhahiso ea mechini: mechine ea boenjiniere, lisebelisoa tsa merafo, sekepe sa khatello.
Indasteri ea likoloi: foreimi, setsi sa lebili, sebopeho sa chassis.
Indasteri ea liphaephe: phala e tjheselitsoeng, phala e potolohang (joalo ka tšepe ea liphaephe tsa API 5L).
Indasteri ea kaho ea likepe: poleiti ea likepe, sebopeho sa bulkhead.
Khamphani e nka boleng ba lihlahisoa e le ba bohlokoa haholo, e tsetela haholo ho hlahiseng lisebelisoa tse tsoetseng pele le litsebi, 'me e etsa sohle se matleng a eona ho fihlela litlhoko tsa bareki lapeng le kantle ho naha.
Dikahare di ka arolwa ka tsela e batlang e le: sebopeho sa dikhemikhale, matla a tlhahiso, matla a ho kgwehla, thepa ya tshusumetso, jj.
Ka nako e ts'oanang, khamphani e ka boela ea etsa lits'ebetso tsa ho lemoha liphoso le ho li kenya ka har'a inthanete le mekhoa e meng ea kalafo ea mocheso ho latela litlhoko tsa bareki.
