Emhlabeni ohlale uvela wokwakha nobunjiniyela bezakhiwo, isidingo sezinto zokwakha ezisezingeni eliphezulu sibalulekile. Phakathi kwalezi zinto zokwakha, i-T-steel iye yavela njengengxenye ebalulekile, ikakhulukazi ngesimo sensimbi eshisayo egoqiwe imishayo ye-T kanye ne-T-steel eshiselwe. Le bhulogi izocubungula izici zesakhiwo, izinzuzo, izinqubo zokukhiqiza, kanye nabakhiqizi abahamba phambili be-T-steel nabahlinzeki, ikakhulukazi egxile ekunikezeni okuqinile okuvela e-China.
Iyini i-T-Steel?
I-T-steel, ebonakala nge-cross-section yayo emise okwe-T, iwuhlobo lwensimbi yesakhiwo esetshenziswa kakhulu ekwakheni nasekusetshenzisweni kobunjiniyela. Ukwakheka kwayo okuyingqayizivele kunikeza amandla amahle kakhulu okuthwala, okwenza kube ukukhetha okuhle kwemishayo, amakholomu, nezinye izingxenye zesakhiwo. Insimbi egoqiwe eshisayo i-T beam iyinhlobonhlobo ethandwayo, ekhiqizwa ngenqubo ehlanganisa insimbi egoqayo emazingeni okushisa aphezulu, okuthuthukisa amandla ayo kanye ne-ductility.
Izimpawu Zesakhiwo kanye Nezinzuzo ze-T-Steel
Izici zesakhiwo se-T-steel zenza kube ukukhetha okuncanyelwayo kwezinhlelo zokusebenza ezahlukahlukene. Nazi ezinye zezinzuzo ezibalulekile:
1. **I-High Strength-to-weight Ratio**: I-T-steel inikeza isilinganiso esimangalisayo samandla nesisindo, esivumela ukwakhiwa kwezakhiwo ezilula ngaphandle kokuyekethisa amandla. Lokhu kunenzuzo ikakhulukazi kumaphrojekthi amakhulu lapho ukwehlisa isisindo kungaholela ekongeni kwezindleko ezibalulekile.
2. **I-Versatility**: I-T-steel ingasetshenziswa ezintweni ezihlukahlukene, kusukela ezakhiweni zokuhlala kuya ezakhiweni zezimboni. Ukuguquguquka kwayo kuyenza ifaneleke kokubili izinhlelo zokusebenza ezithwalayo nezingawuthwali.
3. **Ukwenziwa kalula**: Inqubo yokukhiqiza i-T-steel ivumela ukwakheka okulula nokwenza ngokwezifiso. Lokhu kusho ukuthi i-T-steel ingalungiswa ukuze ihlangabezane nezidingo ezithile zephrojekthi, iqinisekise ukuthi onjiniyela nabadwebi bezakhiwo bangafinyelela izinhloso zabo zokuklama.
4. **Ukuqina**: I-T-steel yaziwa ngokuhlala isikhathi eside kanye nokumelana nezinto zemvelo. Uma iphathwa kahle, ingamelana nokugqwala, iyenze ifaneleke kokubili ukusetshenziswa kwangaphakathi nangaphandle.
5. **Ukusebenza Kahle Kwezindleko**: Ukusebenza kahle kwe-T-steel mayelana nokusetshenziswa kwezinto ezibonakalayo nempilo yayo ende kunomthelela ekongeni kwezindleko zayo. Lokhu kwenza kube inketho ekhangayo kosonkontileka nabakhi abafuna ukwandisa isabelomali sabo.
I-T-Steel Standard Size Comparison Table
Lapho ukhetha i-T-steel yephrojekthi, kubalulekile ukucabangela osayizi abajwayelekile abatholakalayo. Ngezansi ithebula lokuqhathanisa lobukhulu obujwayelekile be-T-steel:
| T-Steel Usayizi (mm) | Ububanzi be-Flange (mm) | Ukujiya Kwewebhu (mm) | Isisindo (kg/m) |
|———————|————————————————————————|
| 100 x 100 x 10 | 100 | 10 | 15.5 |
| 150 x 150 x 12 | 150 | 12 | 25.0 |
| 200 x 200 x 14 | 200 | 14 | 36.5 |
| 250 x 250 x 16 | 250 | 16 | 50.0 |
| 300 x 300 x 18 | 300 | 18 | 65.0 |
Leli thebula lihlinzeka ngereferensi esheshayo yonjiniyela nabadwebi bezakhiwo lapho bekhetha i-T-steel efanele yamaphrojekthi abo.
Inqubo ye-T-Steel kanye nendlela yokukhiqiza
Ukukhiqizwa kwe-T-steel kuhilela izinqubo ezimbalwa ezibalulekile:
1. **Ukukhiqizwa Kwensimbi**: Inqubo iqala ngokukhiqizwa kwensimbi eluhlaza, ngokuvamile kusetshenziswa isithando somlilo esiyisisekelo (i-BOF) noma izindlela ze-arc kagesi (EAF). Le nsimbi eluhlaza ibe isifakwa ezitsheni.
2. **I-Hot Rolling**: Ama-slabs ayashisisa futhi adlule kuma-roller emazingeni okushisa aphezulu ukuze afinyelele isimo se-T esifiswayo. Le nqubo yokuginqika eshisayo ithuthukisa izici zemishini yensimbi, iyenze ibe namandla futhi ibe ne-ductile.
3. **Ukupholisa Nokusika**: Ngemva kokugingqika, i-T-steel iyapholiswa futhi isikwe ubude obudingekayo. Lesi sinyathelo sibalulekile ekuqinisekiseni ukuthi umkhiqizo wokugcina uhlangabezana nobukhulu obucacisiwe nokubekezelela.
4. **Ukulawulwa Kwekhwalithi**: Izinyathelo eziqinile zokulawula ikhwalithi ziyasetshenziswa kuyo yonke inqubo yokukhiqiza ukuze kuqinisekiswe ukuthi i-T-steel ihlangabezana namazinga nezicaciso zemboni.
5. **Ukuqeda**: Okokugcina, i-T-steel ingase ithole ukwelashwa okwengeziwe, okufana nokufaka uthayela noma ukupendwa, ukuze kuthuthukiswe ukumelana nokugqwala nokukhanga kobuhle.
Abakhiqizi nabahlinzeki be-T-Steel abahamba phambili
Uma kuziwa ekutholeni i-T-steel, kubalulekile ukusebenzisana nabakhiqizi nabahlinzeki abahloniphekile. I-Jindalai Steel Company ingumdlali ovelele emakethe ye-T-steel, eyaziwa ngokuzibophezela kwayo kwikhwalithi nokusungula izinto ezintsha. Njengomunye wabakhiqizi abahamba phambili be-T-steel e-China, i-Jindalai Steel Company ihlinzeka ngemishayo yensimbi eshisayo egoqiwe engu-T ehlukahlukene eshiselwe ehlangabezana nezidingo ezahlukahlukene zokwakha.
Ngezigayo zesimanje ze-T-steel kanye nethimba elizinikele lochwepheshe, i-Jindalai Steel Company iqinisekisa ukuthi imikhiqizo yayo ihlangabezana nezinga eliphezulu kakhulu lekhwalithi nokusebenza. Inethiwekhi yabo ebanzi yabahlinzeki be-T-steel ibavumela ukuthi balethe imikhiqizo kahle, okubenza babe ukukhetha okuthembekile kosonkontileka nabakhi emhlabeni wonke.
Isiphetho
Sengiphetha, i-T-steel, ikakhulukazi ewuhlobo lwemishayo yensimbi egoqiwe eshisayo kanye ne-T-steel eshiselwe, idlala indima ebalulekile ekwakhiweni kwesimanjemanje. Izici zayo zesakhiwo, izinzuzo, nokuguquguquka kuyenza ibe into ebalulekile konjiniyela nabadwebi bezakhiwo. Njengoba kunabakhiqizi abahamba phambili njenge-Jindalai Steel Company ehamba phambili, ikusasa le-T-steel libukeka lithembisa, liqinisekisa ukuthi imboni yezokwakha iyaqhubeka nokuchuma ngezinto ezisezingeni eliphezulu, ezihlala isikhathi eside. Noma ngabe ungusonkontileka, umakhi, noma unjiniyela, ukuqonda izinzuzo nokusetshenziswa kwe-T-steel ngokungangabazeki kuzothuthukisa amaphrojekthi akho futhi kube negalelo empumelelweni yawo.
