Carbon steel

Carbon Steel - zentsimbi kunye carbon ingxubevange - kuthatha malunga ne-80% ye-hardware iyonke. Le nto iye iipropati ezanelisayo ngomatshini, iindleko eziphantsi kakhulu kwimveliso. Ukuxinana ngensimbi (7.7 ukuya 7.9) * 103 kg / m3.

Ingxubevange iphathwa uxinzelelo kakuhle kunye ahlabayo. Kufuneka kuqatshelwe ukuba izibonelelo mkhulu kwezi iipropati doped ingxubevange. Nale, workability carbon intsimbi enganeno unyango ubushushu. Ngokunxulumene ngesantya esiphezulu ebalulekileyo yokuqaqadeka, ingxubevange lupholisiwe emanzini. Oku kukhokelela warpage ezibalulekileyo deformation imveliso. Kuba carbon steel waba efanayo ingxubevange doped ngamandla, kuyimfuneko ukuba ndinikhululele kwiqondo eliphantsi. Kulo mba, a egcinwe ombane aphezulu, leyo kunciphisa amandla noshowo mbandela.

Carbon steel ke iintlobo ezimbini: umgangatho ophezulu nomgangatho eqhelekileyo.

Uhlobo lwesibini imelwe imveliso ezityikitywe: imisele, iityhubhu, engile, iimakhishithi, imiqadi, iintonga njalo njalo. In eqhelekileyo kwizinga carbon steel isiqulatho kuvumelekile na inclusions nonmetallic ukungcola eziyingozi. Kwaye savumela iqondo gas Ukwanda mbandela.

Ngokungqinelana ne-iimpawu kunye nenjongo aluminiyamu carbon ezide yahlulwa ngokwamaqela A, B na C.

Iqela lokuqala (A) ezisetyenziswa ukuvelisa iindawo ngaphandle yokusebenza eshushu. Ngoko ke, izinto igcina iipropati mechanical.

Iqela Steel B isetyenziswa ukuvelisa iindawo usebenzisa yokusebenza eshushu (umz, lothuli, elibenze, welding). Kulo mzekelo, iipropati mechanical kunye nesakhiwo lokuqala yatshintsha. Kuba ezi zinto inkcazelo ebalulekileyo malunga nokuqulunqwa imichiza. Kuxhomekeka iinkcukacha iza kumiselwa kwaye imo yokusebenza eshushu.

Yodidi kwiqela B zisetyenziswa imveliso welding izakhiwo iindawo ezibalulekileyo.

Kufuneka kuqatshelwe ukuba indlela ukuzilungisa izinto metal luchaphazela conductivity wobushushu kwensimbi. Ngenxa yoko, nayiphi na impembelelo xi imveliso ye kwandisa ipropati ukuba aqhube ubushushu ukuba inxalenye ashushu amancinci ingxenye eshushu.

Carbon steel komgangatho eziqhelekileyo, amaqela amathathu asetyenziswa ukuvelisa izakhiwo ezahlukeneyo yentsimbi, izixhobo kunye namalungu umatshini olova zilayishwe. Olu hlobo lwezinto kusebenza kwiimeko apho nokusebenza kweemveliso inikezelwa ngqongqo. Carbon steel ezikumgangatho oqhelekileyo ezisetyenziswa kakhulu kwishishini lokwakha ekwakhiweni kwezakhiwo ufakelo lwesamente. amaqela ezahlukeneyo aluminiyamu, B no-D ziphantsi ukusebenza kubanda kakuhle kwaye welding. Ngokuphathelele ezi yodidi ezisetyenziswa xa kusenziwa lezakhelo, iifama nge welding, imibutho yenkxaso, ngokunjalo izinto zokubopha, ezinye apho kamva ufakwa cementation.

Bona yahlukana njengoko eliphezulu, eliphakathi kunye ephantsi-carbon.

Yakutshanje ebonakala ductility eliphezulu namandla ophantsi sikarhulumente abandayo. Ngokuqhelekileyo, la ephantsi-carbon sobhedu yenziwa ube iphepha obhityileyo. Carbon kunye lesilicon ziqulethwe kulo imali encinane, ukwenzela ukuba ezi aluminium zithambe.

Steel Medium (amanani-4 no-3), ebonakala ngamandla aphezulu. Ezi aluminiyamu asetyenziswa ekwenziweni amagiya, emigodini, pulleys kunye nezinye iindawo zolimo kunye neelori, neevili kaloliwe, neentsimbi kunye nezinye iimveliso.

High-carbon intsimbi (amanani-5 no-6) kunye eninzi yemanganizi lisetyenziswa kwiimeko ezininzi ekwenziweni imithombo amandla aphezulu ucingo, imithombo kunye nezinye iindawo ezifuna okubuyela kwimo ephezulu kunye nokumelana lingonakali.
