I-Steel Q195, Q235, umehluko wezinto ezibonakalayo?

Uyini umehluko phakathi kwe-Q195, Q215, Q235, Q255 kanye ne-Q275 ngokwezinto ezibonakalayo?

I-Carbon ehlelekile yensimbi esetshenziswa kakhulu, inani elikhulu kakhulu lokuvalelwa okuvame ukugibela libe yinsimbi, amaphrofayli kanye namaphrofayili, ngokuvamile awadingi ukusetshenziswa okuqondile okuphathwa ngokuqondile, ikakhulukazi kwesakhiwo esijwayelekile kanye nobunjiniyela.

Q195, Q215, Q235, Q255 kanye ne-Q275, njll. , B, c, d) indlela ye-deoxygengeration yezimpawu nokunye ezingxenyeni ezine zokwakheka okulandelanayo. Ukusuka Ekwakhiweni kwamakhemikhali, amamaki ensimbi emnene Izakhiwo zemishini ezivela kumaphuzu, amamaki angenhla akhombisa ukuthi ubukhulu ≤ 16mm wephuzu lesivuno lensimbi. Amandla ayo ashubile abe: 315-430, 335-450, 375-500, 410-550, 490-650, 490-650 (Obn / MM2); I-Qi Elengation yayo yayi: 33, 31, 26, 24, 20 (0.5%). Ngakho-ke, lapho wethula insimbi kumakhasimende, amakhasimende kufanele akhunjuzwe ukuthenga izinto ezahlukene zensimbi ngokuya ngezinto zokwakha ezidingekayo, ukuze kungathinti ikhwalithi yomkhiqizo.

 

Uyini umehluko phakathi kwezinto zokwakha ze-Q235A ne-Q235B?

I-Q235A ne-Q235B yinsimbi yekhabhoni. Ku-National Standard GB700-88, Q235A kanye no-Q235B ngokwezinto ezibonakalayo ngokwezinsimbi ze-carbon, okuqukethwe kwe-Q235A yezinto ezibonakalayo ze-carbon coarbon ku-0,14-0.22% phakathi; Indwangu ye-Q235B ayenzi ukuhlolwa komthelela, kepha imvamisa yenza isivivinyo sokushisa, i-V-notch. Ngokuqhathaniswa nokukhuluma, izakhiwo zemishini zensimbi ye-Q235B zensimbi zingcono kakhulu kunensimbi ye-Q235A. Ngokuvamile, isigayo sensimbi kumaphrofayili aqediwe ngaphambi kokusuka efektri kumakwe kupuleti lokuhlonza. Abasebenzisi bangasho ukuthi okuqukethwe yi-Q235a, Q235B, noma ezinye izinto ezikuleveli yokumaka.

 

Amabanga ensimbi aseJapan areSHC, SPHD, njll. Kusho ukuthini?

I-Steelsen Steel (JIS Series) amamaki ensimbi ejwayelekile ehlelekile ikakhulukazi iqukethe izingxenye ezintathu: Ingxenye yokuqala ikhombisa lokho, okufana: s (i-Steel (i-Ferrum) kusho insimbi. Ingxenye yesibili yemilo ehlukene, izinhlobo, ukusetshenziswa, okufana ne-P (Plate) lelo Plate, T (Tube), K (Kogu) lelo thuluzi. Ingxenye yesithathu yezimpawu zetafula lenombolo, ngokuvamile amandla ashubile. Njengo: SS400 - okokuqala s ukuthi i-steel (ssteel), eyesibili lelo "isakhiwo" (esakhiweni), 400 amandla aphansi wensimbi evamile yensimbi evamile ye-400MPA. Phakathi kwazo:

 

I-SPHD ----- Ibonisa ishidi lensimbi elishisayo eligoqiwe kanye ne-strip yokunyathela.

I-Sphe ------ Ibonisa amashidi ensimbi ashisayo kanye nemichilo yokudweba okujulile.

I-SPCC ------ Ibonisa ama-Carrowed Carbon Insimbi yensimbi kanye ne-strip yokusebenzisa okujwayelekile, okulingana neChina Q195-215A grade. Incwadi yesithathu C yisifinyezo sokubanda, okudingeka ukuthi kuqinisekiswe ukuhlolwa okuthe xaxa ekugcineni kwebanga kanye ne-T ye-SPCCT.

I-SPCD ------ Ibonisa ama-carbon ensimbi ebandayo ne-strip yensimbi yokubhoboza, okulingana neChina 08AL (13237) insimbi ephezulu yekhabhoni.

I-SPCE ------- Ibonisa ama-Carrowed Roll Carbon Insimbi Sheet kanye ne-strip yokudweba okujulile, okulingana neChina 08AL (5213) insimbi yokubhoboza. Ukuqinisekisa ukungasebenzi, engeza u-N ku-SCCEN ekugcineni kwebanga.

Ishidi elibandayo elibandayo le-carbon kanye nokuqokwa kwe-strip, isimo esivelele sokwehla, okujwayelekile okutholwe ku-s, 1/8 kanzima ngo-8, 1/4 kanzima ngo-4, 1/2 kanzima ngo-2.

Ikhodi yokuqeda indawo engaphezulu Ngemuva kwalokho i-SPCCT-SB ikhombisa okujwayelekile, kuqedwe ngokukhanyayo, okubandayo kwekhabhoni ishidi lekhabhoni elinezici eziqinisekisiwe zemishini.
