Ngokwesaziso esivela kwi-United States International Trade Commission (USITC), uMnyango Wezohwebo wase-US…
Insimbi engagqwali igama elinikezwe insimbi ye-alloy ephezulu, esetshenziselwa ikakhulukazi izakhiwo zayo zokulwa nokugqwala.Isici esiyinhloko sohla lwensimbi engagqwali ukuthi zonke ziqukethe okungenani i-chromium engu-10.5%.
Iphesenti lekhabhoni ensimbi lithinta ubulukhuni, amandla okunwebeka kanye nokudumba kwensimbi.Insimbi ethambile, eyaziwa nangokuthi insimbi emnene, inezici ezifanayo ne-ayoni, kodwa ithambile futhi kulula ukuyakheka.
Insimbi eyakhiwe nge-hot-dip galvanized steel ihlanganisa ukusebenza kanye nobuhle. Iqukethe ithini, i-chrome, i-zinc noma upende, okuwukuphela kwento eyengeziwe esetshenziswa ezindaweni zensimbi zemvelo.
I-Aluminium kanye nama-alloys ayo amaningi amelana kakhulu nezinhlobo ezihlukahlukene zokugqwala.Le ndawo yenze i-aluminium yaduma embonini yokwakha, ezobunjiniyela basolwandle kanye nezokuthutha.
Amapayipi ensimbi amashubhu amade angenalutho asetshenziselwa izinjongo ezihlukahlukene.Akhiqizwa ngezindlela ezimbili ezihlukene eziholela kumashubhu ashiselwe noma angenamthungo ukuze asetshenziswe ezindaweni ezihlukahlukene.
Izinsimbi zensimbi zinezinhlobonhlobo zokusetshenziswa kanye nezinhlelo zokusebenza ezihlukahlukene emkhakheni wezimboni.Izinhlobo eziningi zokubunjwa kwe-alloy zingabandakanya insimbi, okwenza kube yinto eguquguqukayo kakhulu yokukhiqiza izinduku zensimbi ye-carbon nezinsimbi zensimbi engagqwali.
I-wire rod iwuhlobo lwensimbi egoqiwe eshisayo ehlukaniswa ngokuma.Kungaba insimbi ye-carbon steel noma umkhiqizo wensimbi engagqwali.Ucingo lusetshenziswa njengezinto zokubopha, iziphethu, amabheringi, izintambo zocingo kanye nezintambo zocingo.
Insimbi inezinto eziningi ezihlukene, kuye ngezinye izakhi eziyenzayo.Insimbi ingenye yezinto ezisetshenziswa kakhulu ekusetshenzisweni kwezimboni kanye nezinto zensimbi ezigaywe kabusha kakhulu emhlabeni.
Ibhalansi yokunikezwa kanye nesidingo izinzile, futhi imakethe yensimbi yaseChina iphinde yavuka kancane kusukela ngoJulayi
