Ndeupi musiyano uripo pakati peQ195, Q215, Q235, Q255 neQ275 maererano nezvinhu?
Carbon dhizaini simbi ndiyo inonyanya kushandiswa simbi, iyo yakakura nhamba inowanzo kukungurutswa kuita simbi, maprofile uye profiles, kazhinji haidi kuve yakananga kushandiswa nekupisa, kunyanya kune yakajairika chimiro uye mainjiniya.
Q195, Q215, Q235, Q255 uye Q275, zvichingodaro, ratidza giredhi resimbi, simbi giredhi nemumiriri wegoho poindi yetsamba (Q), kukosha kwegoho, mhando, mhando nezvimwe zviratidzo (A. , B, C, D) deoxygenation nzira yezviratidzo uye zvakadaro pane zvikamu zvina zvekutevedzana kwekuumbwa. Kubva pamakemikari ekuumbwa, zvinyoro simbi mamakisi Q195, Q215, Q235, Q255 uye Q275 mamakisi akakura, iyo yakakwira iyo kabhoni yemukati, manganese zvirimo, iyo inonyanya kugadzikana plastiki yayo. Mechanical properties kubva pamapoinzi, magiredhi ari pamusoro anoratidza kuti ukobvu ≤ 16mm yegoho resimbi. Simba rayo rekusimba raiva: 315-430, 335-450, 375-500, 410-550, 490-630 (obN / mm2); qi kureba kwayo kwaiva: 33 , 31, 26, 24, 20 (0.5 %). Nokudaro, pakuunza simbi kune vatengi, vatengi vanofanira kuyeuchidzwa kutenga zvinhu zvakasiyana-siyana zvesimbi maererano nezvinodiwa zvechigadzirwa, kuitira kuti zvisakanganise kunaka kwechigadzirwa.
Ndeupi musiyano uripo pakati peQ235A neQ235B zvinhu?
Q235A uye Q235B ese ari maviri kabhoni simbi. Muyero yenyika GB700-88, Q235A uye Q235B mutsauko wezvinhu unonyanya muiyo kabhoni yesimbi, zvinhu zveQ235A zvinhu kabhoni zviri mukati 0.14-0.22 ﹪ pakati; Q235B zvinhu hazviiti bvunzo yekukanganisa, asi kazhinji ita tembiricha yekukanganisa bvunzo, V-notch. Tichienzanisa, ma mechanic zvimiro zveiyo Q235B simbi iri nani kupfuura iyo Q235A simbi. Kazhinji, chigayo chesimbi mumaprofiles akapedzwa asati abva kufekitari anoiswa chiratidzo pandiro yekuzivikanwa. Vashandisi vanogona kutaura kana zvinhu zvacho zviri Q235A, Q235B, kana zvimwe zvinhu zviri pandiro yekumaka.
Japanese simbi mamakisi SPHC, SPHD, etc. Zvinorevei?
Japanese simbi (JIS akatevedzana) mamakisi ezvakajairwa zvimiro simbi kunyanya ine zvikamu zvitatu: chikamu chekutanga chinoratidza zvinhu, senge: S (Simbi) zvinoreva simbi, F (Ferrum) zvinoreva simbi. Chikamu chechipiri chezvimiro zvakasiyana, marudzi, mashandisirwo, akadai seP (ndiro) ndiro iyo, T (chubhu), K (kogu) icho chishandiso. Chikamu chechitatu chetafura maitiro enhamba, kazhinji kacho simba rekushomeka. Zvakadai se: ss400 - yekutanga s kuti simbi (Steel), wechipiri s kuti "chimiro" (Structuree), 400 nokuda kwepasi mutsetse simba 400Mpa zvakajairika structural simbi. Pakati pavo: sphc ---- kutanga Ssteel Steel pfupiso, P yeplate Pate chidimbu, H yekupisa Kupisa chidimbu, Commercial chidimbu, iyo yese inoratidza kuti iyo yakawanda inopisa-yakakunguruswa uye simbi tambo.
SPHD----- inoreva inopisa simbi yakakungurutswa sheet uye tambo yekutsikisa.
SPHE------ inoreva mashizha anopisa akakungurutswa esimbi uye mitsetse yekudhirowa kwakadzika.
SPCC------ inoreva inotonhora yakakungurutswa kabhoni simbi pepa uye tambo yekushandiswa kwese, yakaenzana neChina Q195-215A giredhi. Vara rechitatu C ipfupiso yeCold, inodiwa kuti uve nechokwadi chekuti bvunzo dzekusimba pakupera kwegiredhi pamwe neT yeSPCCT.
SPCD------ inoratidza inotonhora yakakungurutswa kabhoni simbi uye simbi tambo yekubaya, yakaenzana neChina 08AL (13237) yemhando yepamusoro kabhoni structural simbi.
SPCE------ inoreva inotonhora yakakungurutswa kabhoni simbi pepa uye tambo yekudhirowa yakadzika, yakaenzana neChina 08AL (5213) yekubaya simbi. Kuti uone kusashanda, wedzera N kuSPCEN pakupera kwegiredhi.
Cold yakakungurutswa kabhoni simbi shiti uye mitsara yekududza, annealed mamiriro eA, yakajairwa kushatirwa kweS, 1/8 yakaoma ye8, 1/4 yakaoma kune 4, 1/2 yakaoma kune 2.
Surface finish code: hapana gloss finishing yeD, gloss finishing yeB. Zvakadai seSPCCT-SD inoratidza mwero wehasha, hapana gloss inopedza inotonhora yakakungurutswa kabhoni kuti ishandiswe zvakanyanya. Ipapo SPCCT-SB inoratidza yakajairwa kushatirwa, kupenya kupedzwa, inotonhora yakakungurutswa kabhoni pepa rine yakavimbiswa michina zvivakwa.
