Rudzi rweMild Steel Pipe

Pombi yesimbi yakapfava inoreva zviri pasi pe 0.25% kabhoni simbi nekuda kwesimba rayo rakaderera, kuoma kwakaderera uye kupfava.Inosanganisira yakawanda yechikamu cheyakajairwa kabhoni simbi uye yakakwira-mhando kabhoni dhizaini simbi, kazhinji isina kupisa kurapwa kunoshandiswa muinjiniya zvimiro, mamwe carburizing kupisa kupisa uye mamwe ma mechanic parts anodiwa pakupfeka.Munyoro simbi pombi annealing sangano ferrite uye pearlite yakaderera simba rayo uye kuoma, ductility uye kuoma.Naizvozvo, iyo inotonhora formability yakanaka uye inogona kukwiza, kukotama, kubaya uye dzimwe nzira dzekutonhora kuumba.Kufanana nenyere iyo nyoro yesimbi ine weldability yakanaka.Kabhoni yemukati kubva pa0.10 kusvika 0.30% yesimbi yakapfava iri nyore kugamuchira marudzi ese ekugadzirisa senge forging, welding nekucheka, inowanzoshandiswa mukugadzira cheni, rivets, mabhaudhi, shafts, nezvimwe.

Yakajairika mild simbi pombi ndeyekugadzira zvinhu zvekuvaka, midziyo, tangi, choto uye michina yepurazi.Hunhu hunyoro simbi pombi ndeyekugadzira mota cab, hood uye zvimwe zvakadzika-tsvuku zvigadzirwa;zvakare yakakungurutswa mumabhawa, zvinodikanwa zvesimba zvekugadzirwa kwemechini zvikamu.Usati washandisa pombi yesimbi yakapfava kazhinji haisi yekupisa kupisa, iyo kabhoni yemukati inopfuura 0.15% necarburizing kana cyanide kurapwa, inoshandiswa kuda yakakwirira yepamusoro tembiricha, kupfeka zvakanaka shafts, bushings, sprockets nezvimwe zvikamu.Pamusana pesimba rakaderera resimbi-carbon steel, kushandiswa kunorambidzwa.Yakakodzera kuwedzera kabhoni yemukati manganese uye kuwedzera trace vanadium, titanium, niobium uye zvimwe alloying zvinhu, inogona kuvandudza zvakanyanya kusimba kwesimbi.Kana iwe ukadzikisa kabhoni yemukati yesimbi uye wowedzera diki aluminium, uye shoma shoma ye boron carbide kugadzira zvinhu, unogona kuwana ULCB set yakakwira zvakakwana kusimba, uye chengetedza yakanaka ductility uye kuoma.

Yakaderera kabhoni yehunyoro simbi pombi yakaderera kuomarara uye kushomeka machinability, normalizing maitiro anogona kuvandudza machinability.Nyeredzi dzakapfava pombi dzinowanzova nekufamba kwenguva, zvese zvinodzima maitiro ekuchembera, pamwe nekatsika kekunetsa kuchembera.Kana kukurumidza kutonhora kubva kune yakakwira tembiricha simbi, ferritic scraping kabhoni, nitrogen saturation, inogona zvakare kunonoka kuumbwa kwesimbi carbonitride yaive pakamuri tembiricha, uye nekudaro simba nekuoma kwesimbi, kudzikisa ductility uye kuoma, chiitiko chinonzi. kupedza kukwegura.Kunyangwe pasina kudzima uye kutonhora kwekabhoni mhepo kunoburitsa kuchembera.Gadzira yakawanda yakaderera-kabhoni simbi ne deformation dislocations ferrite kubva kabhoni, nitrogen atomu elastic dislocation kupindirana, kabhoni, nitrogen atomu kutonga kwakaungana kutenderedza mutsara usiriwo.Kusanganiswa kwakadaro kwekabhoni nenitrogen maatomu uye mutsara wekubvisa unonzi Coriolis-year-old air mass (Ke lop air mass).Ichawedzera kusimba uye kuoma kwesimbi uku ichidzikisa ductility uye kuomarara, chiitiko chinozivikanwa sekushungurudza kuchembera.Kupfuura kudzima kuchembera kwepombi yesimbi yakapfava panguva yedeformation plasticity uye kuoma kwenjodzi huru muhuremu hwehutete hune pachena hwepamusoro uye hwakaderera goho.Sezvo goho riri pagoho rekurebesa richiitika kusvika kumagumo, rinoonekwa rakaremara nekuda kwekusaenzana kwepamusoro nemapete akaumbwa pamusoro pemuenzaniso, anonzi Luders band.Saka zvitambi zvakawanda zvinowanzoraswa.Pane nzira mbiri dzekudzivirira kwayo.Iyo yakakwira pre-deformation nzira, iyo pre-yakaremara simbi yekutsikisa nzvimbo mushure menguva yenguva ichagadzira Luders bhendi, saka pre-deformed simbi stamping inoiswa nguva isati yasvika isati yanyanya kureba.Imwe simbi, aruminiyamu kana titanium inowedzerwa pakuumbwa kwekamuti yakagadzikana ine nitrogen kudzivirira kuumbwa kwemhepo yakawanda inokonzerwa neCoriolis deformation yekukwegura.
