Okokuqala, izici eziyinhloko ezithinta umphumela wokwelashwa
Izingcezu zikaMary pipe ezibhekene nenani elifanele ngenxa yobubanzi bayo bezinto ze-metamorphism zidinga kakhulu, futhi ngaleyo ndlela kube nzima ukuzinza kunensimbi ye-ductile. Lokhu kudinga ukuthi izinqubo zenqubo efanele kufanele zilwele ukwenza ukungazinzi okuncane. Ukwelashwa umphumela oluthambile ipayipi nokufakwa izinto ezinkulu inqubo izinto ikakhulukazi izici ezilandelayo.
1, okuqukethwe kwesibabule kwensimbi yokuqala eshisayo
Ukuwohloka kokusebenzisa isulphur okuyisisekelo. Inamandla amakhulu kakhulu esalfure yensimbi eshisayo ne-magnesium ephezulu, i-cerium, i-calcium, kukhona okuguquguqukayo okwengeziwe okufakwe ku-slag, ngaleyo ndlela kuncishiswe amandla okubangela ukuwohloka kokwelapha okungaphumelelanga. Ngakho-ke, ekukhiqizeni izinsimbi ezifuthwayo zensimbi kufanele zizame ukusebenzisa insimbi yengulube ne-coke ephansi equkethe isalfure. Izimo, zithathe izinyathelo zangaphambi kokukhishwa kwe-desulphurization kunenzuzo. Lokhu akusho ukuthi ngokuqukethwe okuphezulu kwesibabule kwensimbi encibilikisiwe akunakucutshungulwa ngempumelelo ukufakwa kwamapayipi wensimbi oluthambile. Amafektri amaningi asekhaya nakwamanye amazwe anokuqukethwe kwesibabule afinyelela ku-0.06-0.08% we-cupola eshisayo yensimbi angakhiqizwa ngokuqinile amapayipi wokuthambisa wensimbi, kepha ukuwohloka kwe-alloy okumele kusetshenziswe ngenani elingaphezulu. Imininingwane yokuhlangenwe nakho nge-0.07-0.13% yesulfure ukukhiqizwa kwensimbi eshisayo yensimbi ehlanganisiwe yensimbi engaphansi kwezimo ezithile, njenge-titanium ukukhulisa ububanzi besenzo kusuka ekusetshenzisweni komphumela wokulwa nebhola lesibabule. Noma kunjalo, inani lesibabule lizinzile lisebenza oluthambile ipayipi yensimbi nokufakwa izidingo ezidingekayo.
2, ukushisa kokucubungula kwensimbi encibilikisiwe
Lapho ukwelashwa okuncibilikisiwe kwensimbi encibilikisiwe uGao waba nomthelela omkhulu ezingeni lokumunca i-alloy, ikakhulukazi i-magnesium-based vermicularizing ngisho nangaphezulu. Ukuphakama kwezinga lokushisa, i-magnesium gasification ebilayo enobudlova, ishisa kancane, eminye iphansi ngangokunokwenzeka ukuze namazinga okushisa asebenza kahle. Idokhumenti ichaza lapho usebenzisa i-magnesium titanium composite modifier processing processing oluthambile ipayipi yokufaka, imiphumela yokushisa okwehlukile kokwelashwa ekusebenzeni kahle kokwelashwa. Icubungula ngo 1400 ℃, i-graphite worm-like ezingaphezu kuka 95%, ibhola kuyaqabukela; ekwelashweni okungu-1280, ngaphezu kwengxenye yamaqhuqhuva e-graphite. Inani le-alloy liyalingana, ukushisa kokucubungula kwezinga elikhulu lokumunca elibonakalayo.
Ekukhiqizweni kwangempela, kufanele kubhekwe izinga lokushisa ukucacisa inqubo yokuphonsa izidingo zokushisa okutheliswayo. Kodwa-ke, izinga lokushisa lokucubungula kufanele lizinze ngangokunokwenzeka, uma ukuguquguquka kokushisa kukhulu, inani kufanele lilungiswe ingxubevange, ngaphandle kwalokho kunzima ukuqinisekisa ikhwalithi yokwelashwa.
I-vermicularizing ejwayelekile yomhlaba, ukushisa kokucubungula kuphakeme Ngokuzuzisayo, izinga lokushisa liphansi kakhulu akulula ngisho, ingxubevange engancibiliki ngokuphelele, ngaleyo ndlela kuthinta umphumela wokwelashwa.
3. Ukucubungula imisebenzi
Njengoba inqubo yokungena yenqubo ngenxa yokushintshashintsha kwempendulo ibambeke ibucayi, ngaleyo ndlela kudinga ukuthi umsebenzi ululekwe ukuthi unembe ngokuqinile. Ukufana kokwakheka kwengxubevange, ingxubevange emboza ikesi, ama-alloys we-quantitative kanye ne-iron, i-slag slag nezinye izinyathelo, ezinomthelela oqondile kumphumela wokwelashwa.
