Insimbi Yekhabhoni Ephakeme (Insimbi Yekhabhoni Ephakeme) eyaziwa kakhulu ngokuthi Insimbi Yamathuluzi, okuqukethwe kweCarbon kusuka ku-0.60% kuya ku-1.70%, ukucisha kanye nokufudumeza.Izando nama-crowbars zenziwe nge-0.75% carbon steel;amathuluzi okusika anjengama-drill, ompompi nama-reamers enziwe nge-0.90% kuya ku-1.00% carbon steel.
Ingaphezulu locingo lwensimbi oluyizinsimbi libushelelezi, libushelelezi, alinamifantu, amalunga, ama-prickles, izibazi nokugqwala.Isendlalelo esinama-galvanized yunifomu, ukunamathela okuqinile, ukumelana nokugqwala okuhlala isikhathi eside, ukuqina okuhle kakhulu kanye nokunwebeka.
Ukuqina namandla ensimbi ephezulu ye-carbon ikakhulukazi kuncike enanini lekhabhoni esixazululweni, futhi anda ngenani lekhabhoni esixazululweni.Uma okuqukethwe kwekhabhoni kudlula i-0.6% , ubulukhuni abukhuli, kodwa inani le-carbide eyeqile liyakhula, ukumelana nokugqoka kwensimbi kukhula kancane, futhi i-plasticity, ukuqina nokuqina kuyancipha.
Kulokhu, ngokuvamile ngokuvumelana nezimo zokusetshenziswa kanye namandla ensimbi, ukuqina ukufanisa ukukhetha insimbi ehlukene.Isibonelo, ukwenza ingxenye yentwasahlobo noma yohlobo lwasentwasahlobo ngamandla amancane, khetha insimbi ye-carbon engu-65 # ephezulu enokuqukethwe kwekhabhoni ephansi.I-General high carbon steel ingasetshenziswa esithandweni sikagesi, iziko elivulekile, ukukhiqizwa kwesiguquli se-oxygen.Ikhwalithi ephezulu noma izidingo zekhwalithi ekhethekile zingasetshenziswa ukuncibilikisa kwesithando somlilo kagesi kanye nokusetshenziswa kwe-vacuum noma ugesi, ukuncibilika kwe-slag.
Ekuncibilikeni, ukwakheka kwamakhemikhali, ikakhulukazi okuqukethwe kwesulfure ne-phosphorus, kulawulwa ngokuqinile.Ukuze kuncishiswe ukuhlukaniswa futhi kuthuthukiswe indawo ye-isotropic, i-ingot ingaba ngaphansi kokushisa okuphezulu kokusabalalisa annealing (okubaluleke kakhulu kunsimbi yamathuluzi) .Ngesikhathi sokusebenza okushisayo, izinga lokushisa lokumisa (rolling) lensimbi ye-hypereutectoid liyadingeka ukuthi libe liphansi (cishe 800 ° C).Ngemuva kokubumba nokugingqika, imvula ye-coarse network carbide kufanele igwenywe.Vimbela ukukhishwa kwe-carburization ebusweni ngesikhathi sokwelashwa kokushisa noma ukusebenza okushisayo (okubaluleke kakhulu kunsimbi yasentwasahlobo) .Ngesikhathi sokusebenza okushisayo, kufanele kube nesilinganiso esanele sokucindezela ukuze kuqinisekiswe ikhwalithi nokusebenza kwesevisi yensimbi.
