I-ST12 insimbi egoqiwe ebandayo iyinsimbi egoqiwe eshisayo eseye yacutshungulwa ngokuqhubekayo. Uma insimbi egoqiwe eshisayo isipholile, iyagoqwa ukuze kuzuzwe ubukhulu obunembe kakhudlwana kanye nezimfanelo ezingcono zendawo.
Ishidi lensimbi eligoqiwe elibandayo(Ishidi le-CR steel) empeleni liyinsimbi egoqiwe eshisayo eseye yacutshungulwa ngokuqhubekayo
Ipuleti lensimbi elibandayo 'eligoqiwe' livame ukusetshenziselwa ukuchaza uhla lwezinqubo zokuqeda—kodwa, ngokobuchwepheshe, 'ukugoqwa okubandayo' kusebenza kuphela kumashidi acindezelwa phakathi kwamarola. Izinto ezinjengemigoqo noma amashubhu 'ziyadonswa,' azisongiwe. Ezinye izinqubo zokuphothula ezibandayo zihlanganisa ukuphenduka, ukugaya kanye nokupholishwa—ngayinye isetshenziselwa ukuguqula isitoko esivele sikhona esigoqiwe sibe yimikhiqizo ecwengisiswe kakhulu.
Ikhoyili yensimbi egoqiwe ebandayo ye-ST12 ngokuvamile ingabonakala ngalezi zici ezilandelayo:
1.Insimbi egoqiwe ebandayo inezindawo ezingcono, eziqedwe kakhudlwana ezinokubekezelelana okuseduze
2.Izindawo ezibushelelezi ezivame ukuba namafutha uma uthintwa ngeshidi lensimbi le-CR
3.Amabha ayiqiniso futhi ayizikwele, futhi ngokuvamile anemiphetho namakhona achazwe kahle
4.Amashubhu anokufaniswa okugxilile okungcono kanye nokuqondile, okwenziwe ngezinto ezigoqiwe ezibandayo.
5.Ikhoyili yensimbi egoqiwe ebandayo enezici ezingcono zangaphezulu kunensimbi egoqiwe eshisayo, akumangalisi ukuthi insimbi egoqiwe ebandayo ivame ukusetshenziselwa izinhlelo zokusebenza ezinembe kakhulu noma lapho ubuhle bubalulekile. Kodwa, ngenxa yokucubungula okwengeziwe kwemikhiqizo ebandayo ephelile, iza ngentengo ephakeme.
Ngokuya ngezici zazo ezingokomzimba, izinsimbi ezisetshenziswayo ezibandayo ngokuvamile ziqinile futhi ziqinile kunezinsimbi ezigoqiwe ezishisayo. Lokhu kungenxa yokuthi ukuqedwa kwensimbi egoqiwe ebandayo kudala umkhiqizo onzima kakhulu. Kubalulekile ukuqaphela ukuthi lezi zindlela zokwelapha ezengeziwe zingaphinda zidale ukucindezelwa kwangaphakathi ngaphakathi kokubalulekile. Ngamanye amazwi, lapho wenza insimbi esebenza ngendlela ebandayo—kungakhathaliseki ukuthi iyasikwa, siyigaya noma siyishisela—lokhu kungase kudedele ukungezwani futhi kuholele ekungqubuzaneni okungalindelekile.

Ishidi lensimbi eligoqiwe elibandayo le-ST12, izinhlelo zokusebenza zamakhoyili ensimbi abandayo: ukwakha, ukukhiqizwa kwemishini, ukukhiqizwa kweziqukathi, ukwakha umkhumbi, ukwakhiwa kwebhuloho. Ishidi le-CR steel lingasetshenziswa futhi ukwenza iziqukathi ezahlukahlukene.
Insimbi ye-ST12 nayo isetshenziselwa igobolondo lesithando somlilo, ipuleti lefenisha, ibhuloho kanye
ipuleti lensimbi lemoto elimile, ipuleti lensimbi eliyingxubevange ephansi, ipuleti lokwakha umkhumbi, ipuleti likabhayela, ipuleti lomkhumbi ocindezelayo, ipuleti lephethini, izingxenye zikagandaganda, ipuleti lensimbi lohlaka lwemoto nezinto zokushisela.
Ukupakisha NokuthumelaIpuleti lensimbi eligoqiwe elibandayo le-ST12 elibandayo lipakishwe ngephepha elinsundu kanye nebhokisi lensimbi, ikhoyili yensimbi ebandayo ingahlanganiswa nebhande lensimbi nebhokisi lensimbi .I-Mill's Standard Export Sea-worthy Packing izofanelana nezinsimbi ze-CR.
Inkonzo Yethu1.Yonke i-CR steel inesiqinisekiso sonyaka ongu-1 kusukela ekufakweni kosuku.
2.Konke ukucaciswa kwekhoyili yensimbi egoqiwe ebandayo kanye neminye imininingwane ngeke kuze kuvezwe kunoma yiziphi izinkampani zangaphandle.
3.Singakwazi ukusika insimbi egoqiwe ebandayo isuka kukhoyili yensimbi iye eshidini lensimbi, usayizi uzokwenza njengoba udinga.
4.Siphinde sishisele ipuleti lensimbi eligoqiwe elibandayo lisebenzisa amapuleti ensimbi amabili e-CR.
