Ndeupi musiyano uripo pakati peQ195, Q215, Q235, Q255 uye Q275 maererano nezvinhu?
Carbon Steel ndiyo simbi inoshandiswa zvakanyanya, nhamba huru yeiyo kazhinji yakamanikidzwa kuita simbi, profiles uye kazhinji haifanire kunge ichishandiswa-kurapwa zvakananga, kunyanya kuumbwa uye engineering.
Q195, Q215, Q235, Q255 uye Q275, etc. Steel, ratidziro yemumiriri wetsamba (Q), iyo quality kukosha, mhando, mhando uye zvimwe zviratidzo (a , B, c, d) nzira yekuita yekuita yezviratidzo uye saka pane zvikamu zvina zvezvinyorwa zvekutevedzana. Kubva pamakemikari emakemikari, zvinyoro-nyoro grads q195, q215, Q235, Q255 uye yakakwira kabhoni zvirimo, manganne zvemukati, iyo yakawedzera kupurasitiki. Mechaniki zvivakwa kubva pamapoinzi, iwo mamakisi ari pamusoro anoratidza kuti ukobvu】 16mm yeiyo ereeld pole. Simba rayo rakafanana. 315-430, 335-40, 3755-500, 410-550, 490-630 (OBN / MM2); Qi elonging yayo yaive: 33, 31, 26, 24, 20 (0.5%). Naizvozvo, paunenge uchisuma kune vatengi, vatengi vanofanirwa kuyeuchidzwa kuti vatenge zvinhu zvakasiyana zve simbi zvinoenderana nezvinhu zvinodiwa zvigadzirwa, kuti zvisaite kukanganisa zvigadzirwa.
Ndeupi musiyano uripo pakati peQ235A uye Q235B Zvigadzirwa?
Q235A K35A uye Q235B ndeVose Carbon Simbi. MuNational Standard GB700-88, Q235a uye Q2 Q235B zvinyorwa hazviite quink bvunzo, asi kazhinji zvinowanzoita tembiricha yekubatsira, V-Notch. Kuenzanisa kutaura, izvo zvekushandisa zvezvinyorwa zveQ255B simbi zviri nani kupfuura zvinyorwa q235a simbi. Kazhinji, iyo simbi yeiyo profiles yapera usati wabva mufekitori yakaiswa pachiratidziri. Vashandisi vanogona kutaura kana zvinyorwa zvacho q235a, q235b, kana zvimwe zvinhu pane ndiro yemucherechedzo.
MaJapan Steel Grades ari SPHC, SPHD, etc. Zvinorevei?
Simbi yechiJapan Chikamu chechipiri chemhando dzakasiyana, mhando, zvinoshandiswa, senge p Chetatu chikamu cheiyo tafura maitiro ehuwandu, kazhinji ishoma serisile simba. Yakadai se: SS400 - yekutanga s iyo simbi (ssteel), iyo yechipiri iyo iyo "chimiro" (Chimiro), mazana mana emutsara wetsiva we400mpa akajairwa simbi. Pakati pavo.
SPHD ----- Zvinorevedza Hot yakakundwa simbi simbi uye tambo yekutsvedza.
SPHE ------ zvinoreva kupisa kupisa masimbi mashitsi uye mitsetse yekudhirowa zvakadzika.
SPCC ------------------ unoreva kutonhora kutonhora carbon simbi pepa uye strip yekushandiswa kwakawanda, yakaenzana ne china q195-215a giredhi. Tsamba yechitatu c igure yechitonhora, iyo inodikanwa kuti ive nechokwadi chekuedzwa kwetentile pakupera kwegiredhi pamwe t ye spcct.
Spcd ----------------------
SPCE -------------------------------------------------------------------------------------------------------------------- - 5213) Kuve nechokwadi chekushanda-kushanda, wedzera n kuti utange kumagumo egiredhi.
Kutonhora kukanda carbon simbi pepa uye strip dhizaini, mamiriro akanyorwa a, akaomeserwa nekuda kwe s, 1/8 zvakaoma kwe8, 1/4 yakaoma ye4, 1/2 yakaoma ye2, 1/2 yakaoma ye2.
Kumusoro Kupedzisa kodhi Ipapo SPCCT-SB inoratidza yakajeka, kupinza zvakajeka, kutonhora kukanda carbon bepa neakavimbiswa mechantics zvivakwa.
