Isingeniso
Lapho bethenga amashubhu ensimbi esakhiwo yokwakha, amaphrojekthi elanga, noma ukwenziwa kwezimboni, abathengi bavame ukubhekana nombuzo ovamile: ingabe kufanele bakhethe amashubhu ensimbi ashisiwe noma abandayo?
Amashubhu ensimbi aqediwe ashisayo nabandayo angase abukeke efana, kodwa izinqubo zawo zokukhiqiza zidala umehluko omkhulu emandleni, ukunemba kobukhulu, ukuqeda ubuso, ukusebenza kokwenziwa, kanye nezindleko.
Kumaphrojekthi ensimbi yokwakha, ukukhetha uhlobo lweshubhu olungalungile kungaholela ezindleleni zokucubungula ezingadingekile, ubunzima bokushisela, noma ukwehla kokusebenza kahle kwesakhiwo.
Lo mhlahlandlela uchaza umehluko oyinhloko phakathi kwe-hot rolled kanye ne-amashubhu ensimbi abandayo, okuhlanganisa izinqubo zokukhiqiza, izakhiwo zemishini, izinhlelo zokusebenza, amazinga, kanye nendlela yokukhetha umkhiqizo ofanele iphrojekthi yakho.
Ukuqhathanisa Okusheshayo: Amashubhu Ensimbi Agoqekile Ashisayo vs Abandayo

Uyini Umehluko PhakathiOkugoqiwe OkushisayofuthiAmapayipi Ensimbi Agoqiwe Abandayo?
Nakuba yomibili imikhiqizo isetshenziswa ekwenziweni kwensimbi, umehluko omkhulu uvela enkambisweni yokwakheka.
Ekukhiqizweni kwamashubhu ensimbi akhiwe ngendlela yesakhiwo, "i-hot rolled" ivame ukuhlotshaniswa nezingxenye ezingenalutho eziqediwe ngokushisa, kuyilapho amashubhu amaningi ayisikwele nangunxande ekhiqizwa ngokwakhiwa okubandayo kusuka kumakhoyili ensimbi aqediwe ngokushisa.
Indlela yokukhiqiza ithinta ngqo isimo sobuso bepayipi, ukunemba kobukhulu, ukucindezeleka okusele, kanye nokusebenza kokugcina kokusetshenziswa.
Inqubo Yokukhiqiza: Indlela Amashubhu Agoqekile Ashisayo Nabandayo Enziwa Ngayo
Amapayipi Ensimbi Agoqiwe Ashisayo
Amashubhu ensimbi ashisiwe akhiqizwa emazingeni okushisa angaphezu kwezinga lokushisa lokuvuselelwa kwensimbi, ngokuvamile ngaphezu kuka-926°C.
Emazingeni okushisa aphezulu, insimbi iba thambile futhi kube lula ukuyishintsha, okuvumela abakhiqizi ukuthi bakhiqize izingxenye ezinkulu ezizinzile kahle kwesakhiwo.
Ngemva kokwakheka, insimbi iphola ngokwemvelo ekushiseni kwegumbi. Inqubo yokupholisa kancane isiza ekunciphiseni ukucindezeleka okusele futhi ihlinzeka ngokusebenza kahle kanye nokusebenza kahle kokukhiqiza.
Ukukhiqiza Inqubo
Amapayipi Ensimbi Abandayo
Amashubhu ensimbi akhiwe ngokubandayo akhiqizwa ekushiseni kwegumbi ngezinqubo zokusebenza ezibandayo.
Kumashubhu ayisikwele nangama-rectangular ahlanganisiwe, inqubo ejwayelekile yile:
Ukuqeda Okungaphezulu Nokunemba Okulinganayo
Ukubukeka Komphezulu
Ishubhu Lensimbi Eligoqiwe Elishisayo
Ngesikhathi sokupholisa, ubuso bensimbi eshisayo buphendula nomoya-mpilo bese kwakha i-iron oxide.
Lokhu kudala ungqimba lwesikali se-oxide esimpunga esimnyama, esaziwa kakhulu ngokuthi isikali se-mill.
Izici:
- Ubuso be-oxide emnyama
- Ukuthungwa okuqinile kancane
- Kudinga ukulungiswa kwendawo ngaphambi kokumboza
Ishubhu Yensimbi Ebunjiwe Ebandayo
Ngenxa yokuthi ukukhiqizwa kwenzeka ekushiseni kwegumbi, ayikho inqubo yokushiswa kwe-oxidation yokushisa okuphezulu.
Izici:
- Ubuso obubushelelezi
- Ukubukeka okungcono
- Ubukhulu obufanayo obengeziwe
Ukubekezelelana Okulinganayo
Amashubhu ensimbi ashisiwe avame ukuba nokubekezelelana okubanzi ngoba ukupholisa kungadala ukuhlukahluka kobukhulu.
Amashubhu akhiwe ngokubandayo athola ukubekezelelana okuqinile ngoba acutshungulwa ngama-roller anembile kanye nama-dies.
Ukuqhathaniswa Kwezakhiwo Zemishini
| Impahla | Okushisiwe Okugoqiwe / Okushisayo Okuqediwe | Kwakheka Okubandayo |
| Amandla | Amandla amahle esakhiwo | Amandla aphezulu ekusebenzeni okubandayo |
| Ukuguquguquka | Ngokuvamile kuphakeme | Iphansi uma iqhathaniswa ne-hot rolled |
| Ukucindezeleka Okusele | Ngaphansi | Kuphezulu ngaphandle kokuthi ukucindezeleka kuncishisiwe |
| Ukubekezelelana | Okujwayelekile | Ukuqina |
| Ukuqedwa Komphezulu | Isikali se-okside | Ubuso obubushelelezi |
| Ukwenziwa | Ukushibilika okuhle kakhulu | Kuncike esimweni |
Ngezinhlelo zokusebenza zesakhiwo, amandla aphezulu akusho ngaso sonke isikhathi ukusebenza okungcono.
Ukushibilika, ukuguquguquka, kanye nokulawula ukucindezeleka okusele kuyizinto ezibaluleke ngokulinganayo.
Amashubhu Ensimbi Agoqekile Ashisayo Nabandayo: Yiliphi Okufanele Ulikhethe?
Ukukhetha okuhle kuncike ezidingweni zephrojekthi.
| Isidingo Sephrojekthi | Ukukhetha Okunconyiwe |
| Izakhiwo zensimbi kanye nohlaka lwesakhiwo | I-Hot rolled / hot eqediwe |
| Ukwenziwa kokushisela okunzima | I-Hot rolled |
| Izakhiwo zokufaka ilanga | I-Hot rolled + galvanizing |
| Izakhiwo zangaphandle | I-Hot rolled enokuvikelwa kokugqwala |
| Izingxenye zemishini ezinembile | Kwakheka umkhuhlane |
| Ukubekezelelana okuqinile kobukhulu | Kwakheka umkhuhlane |
Ukusetshenziswa kwamapayipi ensimbi ashubile ashisayo nabandayo
Izakhiwo Zokwakha Nezensimbi
Amashubhu ayisikwele ashisiwe kanye nangama-rectangular asetshenziswa kabanzi ku:

Umhlahlandlela Wokuthenga: Indlela Yokukhetha Umhlinzeki Weshubhu Yensimbi Ofanele
Ukukhetha ishubhu lensimbi elifanele kuyingxenye yenqubo yokuthenga.
Umkhiqizi othembekile kufanele futhi ahlinzeke ngekhwalithi ezinzile, amandla okukhiqiza, ukwesekwa kokuhlola, kanye nokuthembeka kokulethwa.
1. Qinisekisa Izidingo Zobuchwepheshe
Ngaphambi koku-oda, qinisekisa:
- Izinga lomkhiqizo
- Ibanga lensimbi
- Ubukhulu beshubhu
- Ubukhulu bodonga
- Ukubekezelelana
- Izidingo zomhlaba
2. Qinisekisa Amandla Okukhiqiza
Hlola ukuthi umhlinzeki angakunikeza yini:
- Osayizi abadingekayo
- Amazinga ensimbi adingekayo
- Umthamo wokukhiqiza
- Thumela ulwazi
3. Buyekeza Amadokhumenti Ekhwalithi
Isicelo:
- Isitifiketi Sokuhlolwa Komshini (i-MTC)
- Ukwakheka kwamakhemikhali
- Izakhiwo zemishini
- Imibiko yokuhlola
4. Qinisekisa Ukulethwa Nokuhlolwa
Cabanga ngalokhu:
- Isikhathi sokukhiqiza
- Ukupakisha
- Indlela yokuthumela
- Izidingo zokuhlolwa komuntu wesithathu
Kungani Abathengi Bomhlaba Wonke Bekhetha I-Yuantai Derun
Njengoba eneminyaka engaphezu kwengu-20 yesipiliyoni ekukhiqizeni amashubhu ensimbi akhiwe ngendlela yesakhiwo, i-Yuantai Derun inikeza izingxenye eziyizikwele, eziyisikwele, neziyindilinga ezingenalutho zokwakha umhlaba wonke, ingqalasizinda, amandla avuselelekayo, kanye namaphrojekthi ezimboni.
✓ Ukukhiqizwa okuhambisana ne-ASTM A500 / EN10219 / EN10210
✓ Amandla okukhiqiza amakhulu
✓ Ukusekelwa kwesitifiketi sokuhlolwa kwe-Mill
✓ Usekelo lokuhlola lomuntu wesithathu
✓ Ulwazi lokuthumela kwamanye amazwe emhlabeni jikelele
imibuzo ejwayelekile ukubuzwa
Q1Ingabe amashubhu ensimbi asongwe ngokushisa azogqwala?
A: Yebo. Insimbi egoqwe ngokushisa iyinsimbi yekhabhoni engavikelekile futhi izogqwala uma ivezwa umswakama nomoya-mpilo. Ngezicelo zangaphandle, ukulungiswa kwendawo kanye nokugqoka okuvikelayo njengokupenda noma ukugaya ngokushisa kuyanconywa.
Q2. Ingabe i-ASTM A36 ifana nensimbi egoqiwe eshisayo?
A: Cha. I-ASTM A36 ichaza ukwakheka kwamakhemikhali kanye nezidingo zemishini zensimbi, kuyilapho i-hot roll ichaza inqubo yokukhiqiza.
Q3. Ingabe amashubhu ensimbi asongwe ngokushisa angagobeka?
A: Yebo. Amashubhu asongwe ngokushisa ngokuvamile anokuguquguquka okungcono kanye nokucindezeleka okuphansi okusalayo, okwenza afaneleke ezinqubweni eziningi zokugoba kanye nokukhiqiza.
Umbuzo 4. Uyini umehluko phakathi kwe-EN10210 ne-EN10219?
A: I-EN10210 isebenza ezingxenyeni ezingenalutho ezakhiweni eziqediwe ngokushisa. I-EN10219 isebenza ezingxenyeni ezingenalutho ezakhiweni ezihlanganisiwe ezibandayo.
Q5. Ingabe amashubhu asongwe ngokushisa aqinile kunemashubhu abandayo?
A: Hhayi njalo. Ukwakheka okubandayo kungandisa amandla ngokuqiniswa komsebenzi, kuyilapho amashubhu ashisayo evame ukunikeza ukuguquguquka okungcono kanye nokucindezeleka okuphansi okusele.
