Zenziwa kanjani izicucu zensimbi engagqwali?

I-tape yensimbi engagqwali iwuhlobo lwezinto zensimbi ezisetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni, eyaziwa ngokumelana nokugqwala okuhle kakhulu, izakhiwo zokushisa okuphezulu namandla emishini. Ngakho-ke le nto eyisihluthulelo yenziwe kanjani? Okulandelayo kuzokwethula kafushane inqubo yokukhiqiza ibhande lensimbi engagqwali.

 

Ukulungiswa kwezinto zokusetshenziswa

Ukwenziwa kwamabhande ensimbi engagqwali kuqala ngokukhethwa kwezinto ezifanele zokusetshenziswa. Ngokuvamile, izingxenye eziyinhloko zensimbi engagqwali ziyinsimbi, i-chromium ne-nickel, okuqukethwe kwe-chromium okungenani ku-10.5%, okwenza insimbi engagqwali ibe nokumelana nokugqwala okuhle kakhulu. Ngaphezu kwalezi zingxenye eziyinhloko, ezinye izakhi zingase zengezwe ukuthuthukisa izakhiwo zazo, njengekhabhoni, i-manganese, i-silicon, i-molybdenum, ithusi, njll.

 

Ngena esigabeni sokuncibilika

Esigabeni sokuncibilika, izinto ezingavuthiwe ezixubile zifakwa esithandweni se-arc sikagesi noma esithandweni sokufakelwa ukuze sincibilike. Izinga lokushisa ngaphakathi kwesithando somlilo ngokuvamile lifinyelela cishe ku-1600 degrees Celsius. Insimbi ewuketshezi encibilikisiwe iyacwengwa ukuze kukhishwe ukungcola namagesi kuyo.

 

Thela emshinini wokuphonsa oqhubekayo

Insimbi engagqwali ewuketshezi ithululelwa emshinini wokuphonsa oqhubekayo, futhi umugqa wensimbi engenasici ukhiwa ngenqubo yokuphonswa okuqhubekayo. Kule nqubo, insimbi engagqwali ewuketshezi iqhubeka iphonswa esikhunjeni esijikelezayo ukuze kwakheke umucu ongenalutho wogqinsi oluthile. Izinga lokupholisa kanye nokulawulwa kwezinga lokushisa kwesikhunta kunomphumela obalulekile kwikhwalithi nokusebenza komugqa.

 

Ngena esiteji sokuginqika esishisayo

I-billet iyashisa igoqwe umshini wokugaya oshisayo ukuze wenze ipuleti lensimbi enogqinsi nobubanzi obuthile. Ngesikhathi senqubo yokugoqa okushisayo, ipuleti lensimbi lingaphansi kokugingqika okuningi kanye nokulungiswa kwezinga lokushisa ukuze kutholwe usayizi odingekayo kanye nezakhiwo.

 

Isiteji sokukha

Kule nqubo, umugqa wensimbi engagqwali ucwiliswa kusisombululo esimuncu ukuze kukhishwe ama-oxide angaphezulu nokungcola. Ingaphezulu lomugqa wensimbi engagqwali ngemva kokuchotshozwa libushelelezi, okunikeza isisekelo esihle sokugoqa okubandayo okulandelayo nokwelashwa kwendawo.

 

Isiteji sokugoqa esibandayo

Kulesi sigaba, umugqa wensimbi engagqwali uphinde ugoqelwe emshinini obandayo ukuze uqhubeke nokulungisa ukushuba kanye nokucaba kwawo. Inqubo yokugoqa ebandayo ingathuthukisa ikhwalithi ephezulu kanye nokunemba komugqa wensimbi engagqwali.

 

Isigaba sokugcina

Ngemva kochungechunge lwezinqubo zangemuva kokwelashwa ezifana nokucwiliswa, ukupholishwa nokusika, umugqa wensimbi engagqwali ekugcineni uqeda inqubo yokukhiqiza. Inqubo ye-annealing ingaqeda ukucindezeleka ngaphakathi komugqa wensimbi engagqwali, ithuthukise ipulasitiki yayo nokuqina; Inqubo yokupholisha ingenza ubuso bomugqa wensimbi engagqwali busheleleke futhi bukhanye; Inqubo yokusika isika umugqa wensimbi engagqwali ube ubude nobubanzi obufunekayo njengoba kudingeka.

 

Ngokufigqiwe

Inqubo yokukhiqiza umugqa wensimbi engagqwali ibandakanya ukulungiswa kwempahla eluhlaza, ukuncibilika, ukubunjwa okuqhubekayo, ukuginqika okushisayo, ukuqoqwa, ukugoqa okubandayo kanye nokwelashwa ngemva kokwelashwa nezinye izixhumanisi. Isinyathelo ngasinye sidinga ukulawulwa okunembile kwamapharamitha wenqubo namazinga ekhwalithi ukuze kuqinisekiswe ukuthi umkhiqizo wokugcina uhlangabezana nezidingo zekhwalithi. Ukusetshenziswa okubanzi kwemichilo yensimbi engagqwali kungenxa yokumelana nokugqwala okuhle kakhulu kanye nezakhiwo zemishini, futhi ukulawulwa okuhle kwenqubo yokukhiqiza kuyisihluthulelo sokufeza lezi zakhiwo.
