Ukusetshenziswa kwezinto nakho kubaluleke kakhuluisikulufu esingejwayelekile, kanyeisikulufu esenziwe ngokwezifisoizinto ezingasetshenziswa ezinhlotsheni ezahlukene zihlukile, njengezindinganiso zokusebenza kwezinto ezahlukene, njll., ngokusho kwe-isikulufu semakethe yamanjeUmkhiqizi ikakhulukazi uhlanganisa insimbi yekhabhoni, insimbi engagqwali, ithusi izinto ezintathu.
1. Kungani ukhethe insimbi yekhabhoni, insimbi engagqwali, ithusi?
Insimbi yekhabhoni: Sihlukanisa phakathi kwensimbi yekhabhoni ephansi, insimbi yekhabhoni ephakathi nendawo kanye nensimbi yekhabhoni ephezulu, kanye nensimbi ye-alloy ngenani lekhabhoni ensimbini yekhabhoni.
(1) Insimbi ekhabhoni ephansi C%≤0.25% ivame ukwaziwa njengensimbi ye-A3 eShayina. Amazwe angaphandle abizwa ngokuthi i-1008, 1015, 1018, 1022, njll. Isetshenziswa kakhulu emikhiqizweni engenazo izidingo zokuqina njengemibhoshongo yebanga elingu-4.8, amantongomane ebanga elingu-4 kanyeizikulufo ezincane(Qaphela: Izinto ezingu-1022 zisetshenziswa kakhulu ezipikilini zokubhoboza.)
(2) Insimbi yekhabhoni ephakathi nendawo engu-0.25%
(3) Insimbi enekhabhoni ephezulu C%>0.45%. Okwamanje, empeleni ayisetshenziswa emakethe
(4) Insimbi ye-alloy: ukwengeza izakhi zokuhlanganisa ensimbini yekhabhoni evamile ukuze kwandiswe ezinye izakhiwo ezikhethekile zensimbi: njenge-35, 40 chromium molybdenum, SCM435, 10B38. Izikulufo ze-Panvo zisebenzisa kakhulu insimbi ye-alloy ye-chrome ye-SCM435, kanti izingxenye eziyinhloko yi-C, Si, Mn, P, S, Cr, kanye ne-Mo.
Isikulufu sensimbi yekhabhoniinamandla aphezulu kanye nobunzima, ukumelana nokuguguleka okuhle, i-plasticity eqinile, kanye nezindleko zokukhiqiza eziphansi. Lezi zakhiwo zenza insimbi yekhabhoni ibe yinto efanelekile yokwenza izingxenye ezijwayelekile.
Insimbi engagqwali: izinga lokusebenza: 45, 50, 60, 70, 80
Izingxenye eziyinhloko yi-austenite (18%Cr, 8%Ni), enokumelana okuhle nokushisa, ukumelana okuhle nokugqwala kanye nokushibilika okuhle. I-A1, A2, A4 martensitic kanye ne-13%Cr zinokumelana okubi nokugqwala, amandla aphezulu kanye nokumelana okuhle nokuguguleka. Insimbi engagqwali ye-ferritic C1, C2, C4. Ukuphazamiseka kwe-18%Cr kungcono, futhi ukumelana nokugqwala kunamandla kunokwe-martensite. Njengamanje, izinto ezingeniswa emakethe ikakhulukazi yimikhiqizo yaseJapan. Ngokwezinga, ihlukaniswe kakhulu yi-SUS302, SUS304, kanye ne-SUS316.
Isikulufu sensimbi engagqwaliinokumelana nokugqwala okuhle kakhulu, ingagcinwa isesimweni esihle isikhathi eside ezindaweni ezinzima, futhi akulula ukuyigqwala. Ngaphezu kwalokho, insimbi engagqwali inezici zamandla aphezulu, ubuhle obuhle, kanye nokucutshungulwa okulula.
Ithusi: Izinto ezisetshenziswa kakhulu yithusi... Ingxubevange ye-zinc-copper. Ithusi le-H62, i-H65 kanye ne-H68 lisetshenziswa kakhulu njengezingxenye ezijwayelekile emakethe.
Isikulufu sethusiine-conductivity enhle kagesi, i-conductivity yokushisa, ukumelana nokugqwala kanye nezakhiwo zokucubungula, futhi ingashintshwa futhi ifakwe i-braze. Lezi zakhiwo zenza ithusi libe usizo ekudlulisweni kwamandla, ezinjinini
2 Uyini umehluko phakathi kwensimbi engagqwali nensimbi yekhabhoni?
Insimbi engagqwali kanye nensimbi yekhabhoni nakho kuyizinto zensimbi, futhi abantu abaningi abazi ukuthi umehluko phakathi kwensimbi engagqwali kanye nensimbi yekhabhoni uzoba yini.
Uyini umehluko phakathi kwensimbi engagqwali nensimbi yekhabhoni? Kuye ngenhloso kanye nomphumela wokusebenza, ngokuvamile kuba nomehluko olandelayo:
(1) Insimbi engagqwali inokushisa okubi kanye nobude obuphansi ngenxa yokushisa kwayo okubi kanye nobude, ngakho-ke amandla okuguquka adingekayo makhulu;
(2) Uma kuqhathaniswa nensimbi yekhabhoni, ipuleti lensimbi engagqwali linokuthambekela okukhulu kokubuyela emuva lapho ligoba;
(3) Uma kuqhathaniswa nensimbi yekhabhoni, ngenxa yokwelulwa okuphansi kwepuleti lensimbi engagqwali, i-engeli yokugoba u-R wento yokusebenza kufanele ibe nkulu kuneyensimbi yekhabhoni lapho igoba, ngaphandle kwalokho kungenzeka kube nemifantu;
(4) Ngenxa yobunzima obukhulu bepuleti lensimbi engagqwali kanye nomthelela obalulekile wokuqina komsebenzi obandayo, lapho kukhethwa amathuluzi okugoba okucindezelwayo, insimbi yamathuluzi enobunzima bokwelashwa kokushisa obungaphezu kwama-HRC angu-60 kufanele ikhethwe, futhi ubulukhuni bayo bomphezulu kufanele budingeke.
E-Yuhuang,umenzi wezikulufo zaseShayinasiyazi ukuthiisikulufu sekhwalithi ephezuluizinto zokusetshenziswa ziyisisekelo sokudala imikhiqizo emihle kakhulu. Ngakho-ke, ngayinyeisikulufuYenziwe ngensimbi enamandla kakhulu ye-alloy, insimbi engagqwali kanye nezinye izinto ezithuthukisiwe ezihlolwe ngokucophelela ukuqinisekisa ukuthi ayinawo nje kuphela amandla aqinile okuthwala umthwalo kanye nokumelana nokugqwala, kodwa futhi igcina isimo sokusebenza esizinzile nesithembekile ezindaweni ezimbi kakhulu. Ukukhetha izikulufo ze-Yuhuang, ukhetha isiqinisekiso sekhwalithi esingenaphutha.
