Umkhiqizi wamashubhu ensimbi engenamthungo uzokwethula kafushane ukuhlukaniswa okuqondile kanye nomsebenzi weshubhu lensimbi ye-carbon.

1. General carbon steel tube

Ngokuvamile, insimbi enokuqukethwe kwekhabhoni engu-≤0.25% ibizwa nge-low-carbon steel.Isakhiwo esihlanganisiwe sensimbi ye-low-carbon yi-ferrite kanye nenani elincane le-pearlite.Inamandla aphansi nobulukhuni, ipulasitiki enhle nokuqina, futhi kulula ukuyidweba, isitembu, i-extrude, i-Forging ne-welding, phakathi kwayo i-20Cr steel isetshenziswa kabanzi.Insimbi inamandla athile.Ngemva kokucisha kanye nokushisa ezingeni lokushisa eliphansi, le nsimbi inezici ezinhle zokusebenza ezibanzi, ukuqina komthelela wezinga lokushisa eliphansi, kanye nokufutheka akubonakali.

Isebenzisa:Embonini yokukhiqiza imishini, ilungele ukwenza izingxenye zesakhiwo ezishiselwe kanye nezingxenye ezingekho ngaphansi kwengcindezi ephezulu ngemuva kokubumba, ukugxiviza okushisayo kanye nomshini.Embonini yokukhiqiza i-steam turbine kanye ne-boiler, isetshenziselwa kakhulu amapayipi, ama-flange, njll. asebenza kumidiya engagqwali.Izihloko nezinsimbi ezihlukahlukene;futhi ilungele ukukhiqizwa kwezingxenye ezincane neziphakathi nendawo kanye nezingxenye ze-carbonitriding ezimotweni, ogandaganda nokukhiqizwa kwemishini ejwayelekile, njengezicathulo zamabhuleki esandla, ama-lever shafts, namafoloko esivinini se-gearbox ezimotweni, amagiya okudlulisa kanye nama-camshaft kugandaganda, ibhalansi yokumiswa. ama-shafts, ama-bushings angaphakathi nangaphandle ama-balancers, njll.;ekwenziweni kwemishini esindayo nephakathi nendawo, njengezinduku zokubopha ezifojiwe noma ezicindezelwe, amaketango, amalevu, imikhono, izinto ezilungiswayo, njll.

2. Ishubhu yensimbi ye-carbon ephansi
Insimbi enekhabhoni ephansi: Insimbi enekhabhoni ephansi enokuqukethwe kwekhabhoni engaphezu kuka-0.15% isetshenziselwa ama-shafts, ama-bushings, ama-sprockets, nokunye ukubunjwa kwepulasitiki okudinga ubulukhuni obuphezulu nokumelana okuhle kokugqoka ebusweni ngemuva kokungcwatshwa kwe-carburizing kanye nokucisha kanye nokushisa okuphansi.Isakhi.Ngemuva kokungcwatshwa kwe-carburizing kanye nokucisha kanye nezinga lokushisa eliphansi, insimbi enekhabhoni ephansi inesakhiwo se-high-carbon martensite phezulu kanye ne-low-carbon martensite phakathi nendawo, ukuze kuqinisekiswe ukuthi ubuso bunokuqina okuphezulu kanye nokumelana nokugqokwa okuphezulu ngenkathi. isikhungo sinobunzima obuphezulu kakhulu.Amandla amahle nokuqina.Ilungele ukwenza izicathulo zamabhuleki esandla, ama-lever shaft, amafoloko esivinini se-gearbox, ama-transmission passive gears, ama-camshaft akugandaganda, ama-suspension balancer shafts, ama-balancers angaphakathi nangaphandle, imikhono, izinto zokulungisa nezinye izingxenye.

3. Ithubhu yensimbi ye-carbon ephakathi
Insimbi enekhabhoni emaphakathi: Insimbi yekhabhoni enokuqukethwe kwekhabhoni okungu-0.25% kuya ku-0.60%.I-30, 35, 40, 45, 50, 55 namanye amabanga angawensimbi ye-medium-carbon.Ngenxa yokuthi okuqukethwe kwe-pearlite ensimbi kuyanda, amandla ayo nobulukhuni buphakeme kunangaphambili.Ukuqina kungandiswa kakhulu ngemuva kokucisha.Phakathi kwabo, insimbi engu-45 iyona ejwayelekile kakhulu.Insimbi engu-45 iyinsimbi enamandla aphakathi nendawo enekhabhoni ecishiwe futhi epholile, enobupulasitiki obuthile nokuqina, nokusebenza okuhle kokusika.Ingathola izici ezinhle eziphelele zemishini ngokucisha kanye nokwelashwa kokushisa, kodwa ukuqina kwayo akulungile.Isetshenziselwa ukwenza izingxenye ezinezidingo zamandla aphezulu kanye nokuqina okuphakathi.Ngokuvamile isetshenziswa esimweni sokucisha nesithambile noma esijwayelekile.Ukuze wenze insimbi ibe nokuqina okudingekayo futhi iqede ukucindezeleka kwayo okusele, insimbi kufanele icime bese ifakwa ku-sorbite.
