Hlola ukuthi ummese uzowusebenzisa yini, into yokuqala okufanele uyicabangele ibukhali.
Izinga elibukhali lezici eziyinhloko ubulukhuni bensimbi (
硬度)
.
Ake sithi kunemimese emibili, owodwa wenziwe ngensimbi ethambile, omunye wenziwe ngensimbi eqinile.
Ukuwagaya abukhali ngokwedlulele, ukuthi noma ayafana?
Impendulo ithi cha, ngoba ubukhali bensimbi ethambile ngokushesha.
Ngakho ukuphikelela ukugcina ubukhali kuncike kakhulu ekhonweni lobulukhuni bensimbi, kuyisici esiyinhloko esahlulela ukusebenza kommese.
Ngaphezu kokubona impumelelo yokuqina kwensimbi yasekhishini nokumelana nokugqwala, ukumelana nokugqoka, ukuqina, ubulukhuni nokuqina kuyaphikisana, ubulukhuni,
Okuqukethwe kwekhabhoni)
Ukumelana nokugqoka kanye nokumelana nokugqwala kuvame ukuphikisana, isici singenza ikhishi lihlale libukhali isikhathi eside kodwa kuzoba nzima ukuligaya.
Insimbi engagqwali neminye imikhiqizo yensimbi, awukho umehluko obalulekile phakathi ngenxa nje yokuqukethwe okuphezulu kwe-chromium, i-chrome oxide eyakhiwe endaweni yensimbi ukuvimbela i-iron oxide, uma kwenzeka kuba namabhamuza amade kungenzeka ukuthi agqwale.
Izitolo ezinkulu ezijwayelekile ezingama-420 zensimbi engenasici zithengisa ummese wekhishi osezingeni eliphansi unezinjongo eziningi, ushibhile futhi ukumelana nokugqwala okuhle kakhulu, kepha okuqukethwe kwekhabhoni kuphansi kakhulu, ngakho-ke ubulukhuni obuphansi abukho ngaphezu kwama-52, bucishe bulingane nendawo yethu yasekhaya evame ukusetshenziswa. insimbi ezintathu ze-chrome (
Inani libhekisela kokuqukethwe kwekhabhoni yenombolo yangaphambilini nge-mil)
.
I-X50CrMoV15 i-ashkenazi yensimbi evamile yommese wasekhishini, ukumelana nokugqwala okuhle, ukuqina, kodwa okufiphele ngokushesha.
Kodwa ukunakekelwa okuhle akukwazi ukunqamula ukuwohloka, okulingana cishe nommese wethu wensimbi ongu-5 we-chrome osetshenziswa kakhulu ekhaya.
Yebo ukusebenza kwensimbi ye-chrome engu-5 kungcono kunensimbi evamile ngokwayo, ngemuva kokuphathwa kokushisa okuyingqayizivele komkhiqizi nakho kunokuphromotha okuthile, kodwa izithako ezikhona zisebenza okuvamile.
Ikhaya linommese wekhishi wokuqina ofanayo osetshenziselwa ukusika izimbambo eziwugqinsi, inkukhu enqunywe emhlophe, chop ukuthi iyiphi ingulube enhle kakhulu, kodwa imifino enqunywe inyama ngokusobala izozwakala kunensimbi yaseJapane.
Ummese wasekhishini waseJapane ngaphandle kwensimbi, lapha nje ngenxa yokungafani.
I-Molybdenum vanadium insimbi engagqwali (
AUS-
8)
Ukuqina kungaphansi kuka-58, omunye ummese wekhishi osezingeni lokungena osetshenziswa e-Japan, insimbi ye-chrome eyisishiyagalombili yasekhaya, insimbi ye-chrome 9 ubulukhuni obufanayo.
VG -
I-10 Japanese 'inkampani yami ekhethekile yensimbi ekukhiqizeni insimbi engagqwali ephezulu, ivamile kummese wasekhishini waseJapane, ibuye ifaneleke kakhulu kubantu ababalulekile.
Gcina idigri ebukhali ilungile, ubulukhuni buphezulu, futhi akulula ukugqwala, kodwa okuqukethwe kwekhabhoni ephezulu ngaphansi kuka-5 chrome ukumelana nokugqwala kwensimbi.
Kukhona imvelo cishe ephansi-ekupheleni VG1 steel, ubulukhuni, mayelana 60.
I-Molybdenum vanadium insimbi engagqwali (
AUS-
8)
Ukuqina kungaphansi kuka-58, omunye ummese wekhishi osezingeni lokungena osetshenziswa e-Japan, insimbi ye-chrome eyisishiyagalombili yasekhaya, insimbi ye-chrome 9 ubulukhuni obufanayo.
I-powder steel powder metallurgy (
粉末冶金)
Iwumkhiqizo wobuchwepheshe besimanje be-metallurgical, iwuhlobo lwempushana yensimbi njengempahla eluhlaza, ngokucindezela kanye nokucubungula izindlela ze-sintering zezinhlobo ezahlukene zemikhiqizo.
Ngenxa yokuthi i-powder steel okukhiphayo ngonyaka kungamathani ayizinkulungwane ezingamashumi amahlanu kuphela, ngobuchwepheshe bolwazi oluyinkimbinkimbi kuphela abakhiqizi abambalwa, oluphezulu ngaphezu kwentengo yeqiniso.
