Simbi, kusanganisira zvinhu zvesimbi, inoedzwa mhando nenzira dzakasiyana siyana, kusanganisira kuyedza kusimba, kuyedzwa kuneta kwekukotama, kuyedzwa kwekumanikidza / kukotama uye kuyedzwa kwekupokana.Zvishandiso uye zvigadzirwa zvine hukama zvinogona kuvandudzwa uye kugadzirwa munguva chaiyo kuti urambe uchiteedzera maitiro emhando yechigadzirwa, izvo zvinogona kudzivirira kudzoka nekuda kwemhando uye kutambisa zvigadzirwa.
Kune marudzi akawanda akajairika esimbi.
Carbon Steel
Carbon steel, inozivikanwawo secarbon steel, isimbi-carbon alloy ine kabhoni yemukati (wc) isingasviki 2%.Pamusoro pekabhoni, kabhoni simbi inowanzo ine shoma shoma yesilicon, manganese, sarufa uye phosphorus.
Carbon simbi inogona kukamurwa kuita zvikamu zvitatu: kabhoni structural simbi, kabhoni mudziyo simbi uye yemahara-kucheka simbi yekugadzira.Carbon structural simbi inogona zvakare kukamurwa kuita mhando mbiri dzesimbi yekuvaka nekuvaka muchina.
Maererano nekabhoni yemukati inogona kukamurwa kuita yakaderera kabhoni simbi (wc ≤ 0.25%), kabhoni simbi (wc 0.25% ~ 0.6%) uye yakakwira kabhoni simbi (wc> 0.6%).Zvinoenderana nefosforasi, sulfur yemukati inogona kukamurwa kuita yakajairwa kabhoni simbi (ine phosphorus, sarufa yakakwirira), yepamusoro kabhoni simbi (ine phosphorus, sarufa yakaderera) uye yepamusoro simbi yemhando (ine phosphorus, sarufa yakaderera).
Iyo yakakwirira iyo kabhoni yemukati mune yakawanda kabhoni simbi, iyo yakakwirira kuoma uye kusimba, asi iyo plasticity inoderedzwa.
Carbon structural steels
Iyi mhando yesimbi inonyanya kuve nechokwadi chemichina yezvivakwa, saka giredhi rayo rinoratidza maitiro ayo emagetsi, nenhamba dzeQ +, uko "Q" yegoho poindi "Qu" hunhu hwekutanga Hanyu Pinyin, nhamba inoratidza kukosha kwegoho, semuenzaniso, Q275 yakati goho poindi ye275MPa.Kana iyo giredhi yakanyorwa nemabhii A, B, C, D, zvinoreva kuti mhando yegiredhi yesimbi yakasiyana, ine huwandu hweS, P kuitira kuderedza huwandu hwemhando yesimbi kuitira kuti uvandudze.Kana tsamba "F" yakanyorwa kuseri kwegiredhi, iri kufashaira simbi, yakanyorwa "b" ye semi-sedentary simbi, isina kunyorwa "F" kana "b" ye sedentary simbi.Semuenzaniso, Q235-AF zvinoreva A-grade simbi inofashaira ine goho re235 MPa, uye Q235-c inoreva c-grade quiescent simbi ine goho re235 MPa.
Carbon structural simbi dzinowanzo shandiswa pasina kupisa kupisa uye mune inopihwa mamiriro zvakananga.Kazhinji Q195, Q215 uye Q235 masimbi ane yakaderera misa chikamu kabhoni, yakanaka welding zvivakwa, yakanaka plastiki uye kuoma, ane rimwe simba, uye anowanzo kukungurutswa kuita mahwendefa matete, mbariro, welded simbi mapaipi, nezvimwewo, anoshandiswa mumabhiriji, zvivakwa uye zvimwe zvimiro uye mukugadzira zvakajairika rivets, screws, nzungu uye zvimwe zvikamu.Q255 neQ275 simbi dzine chikamu chepamusoro-soro chekabhoni, simba repamusoro, purasitiki iri nani uye kuoma, inogona kugadzirwa, uye inowanzokungurutswa. sekubatanidza tsvimbo, magiya, couplings nemapini.
