Isingeniso Kulayini Wokukhiqiza we-Threaded Steel
Insimbi enemicu, eyaziwa nangokuthi i-rebar noma insimbi eqinisayo, iyingxenye ebalulekile esetshenziswa kumaphrojekthi wokwakha emhlabeni wonke.Isetshenziselwa ngokuyinhloko ukuqinisa izakhiwo zekhonkrithi ukwandisa amandla nokuqina kwazo.Ukukhiqizwa kwensimbi enezintambo kudinga uchungechunge lwezinqubo eziyinkimbinkimbi, konke okubalulekile ekuqinisekiseni ikhwalithi nokuvumelana komkhiqizo wokugcina.
Ulayini wokukhiqiza wensimbi enentambo ngokuvamile uqala ngokuncibilika kwezinsimbi ezilahliwe esithandweni somlilo se-arc sikagesi.Insimbi encibilikisiwe ibe isidluliselwa esithandweni seladle, lapho icwengwa khona ngenqubo eyaziwa ngokuthi i-secondary metallurgy.Le nqubo ihilela ukungezwa kwama-alloys ahlukahlukene kanye nezakhi ukuze kulungiswe ukwakheka kwamakhemikhali ensimbi, ukuthuthukisa izakhiwo zayo kanye nokuqinisekisa ukufaneleka kwayo ukuze kusetshenziswe izicelo zokwakha.
Ngemva kwenqubo yokucwenga, insimbi encibilikisiwe ithululelwa emshinini wokuphonsa oqhubekayo, lapho iqiniswa khona ibe amabhilidi anobukhulu obuhlukahlukene.Lawa mabhilidi abe esedluliselwa emshinini wokugaywa, lapho eshiselwa khona emazingeni okushisa aphezulu futhi adliwe ngochungechunge lwezigayo eziginqikayo kanye nemibhede yokupholisa ukuze kukhiqizwe umkhiqizo wokugcina.
Phakathi nenqubo yokugoqa, ama-billet adluliswa ochungechungeni lwama-rollers anciphisa kancane kancane ububanzi bensimbi yensimbi ngenkathi ekhulisa ubude.Khona-ke induku isikwa ibe ngobude obufunekayo futhi idliwe ngomshini wokulutha okhiqiza imicu endaweni yensimbi.Inqubo yokulutha ihlanganisa ukugingqa insimbi phakathi kwama- dies amabili anemigqa, okucindezela imicu phezu kwensimbi, okuqinisekisa ukuthi iqondane kahle futhi ihlukene.
Insimbi enentambo ibe isipholiswa, ihlolwe, futhi ihlanganiswe ukuze ihanjiswe kumakhasimende.Umkhiqizo wokugcina kufanele uhlangabezane nezidingo zekhwalithi eziqinile, okuhlanganisa amandla aqinile, i-ductility, nokuqina.Izinyathelo zokulawula ikhwalithi zikhona kuzo zonke izigaba zenqubo yokukhiqiza ukuze kuqinisekiswe ukuthi umkhiqizo wokugcina uhlangana noma udlula indawo yemboni.
