Insimbi Q195, Q235, umehluko wezinto ezibonakalayo?

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

Insimbi yesakhiwo sekhabhoni iyinsimbi esetshenziswa kakhulu, inombolo enkulu kunazo zonke evamise ukugoqwa ensimbi, amaphrofayili namaphrofayili, ngokuvamile ayidingi ukusetshenziswa okuqondile okuthela ukushisa, ikakhulukazi ukwakheka okujwayelekile nobunjiniyela.

I-Q195, i-Q215, i-Q235, i-Q255 ne-Q275, njll., ngokulandelana, ikhombisa izinga lensimbi, ibanga lensimbi ngummeleli wephoyinti lokukhiqiza lencwadi (Q), inani lephoyinti lesivuno, ikhwalithi, ikhwalithi nezinye izimpawu (A , B, C, D) indlela ye-deoxygenation yezimpawu nokunye izingxenye ezine zokwakheka okulandelanayo. Kusukela ekubunjweni kwamakhemikhali, amamaki ensimbi athambile Q195, Q215, Q235, Q255 kanye ne-Q275 amamaki amakhulu, ukuphakama kwekhabhoni, okuqukethwe kwe-manganese, ipulasitiki yayo izinzile. Izakhiwo zemishini ezivela kumaphuzu, amamaki angenhla abonisa ukuthi ubukhulu ≤ 16mm wephuzu lokukhiqiza lensimbi. Amandla ayo aqinile: 315-430, 335-450, 375-500, 410-550, 490-630 (obN/mm2); qi ubude bayo bekungu: 33 , 31, 26, 24, 20 (0.5 %). Ngakho-ke, lapho wethula insimbi kumakhasimende, amakhasimende kufanele akhunjuzwe ukuthi athenge izinto ezahlukene zensimbi ngokusho kwempahla edingekayo yomkhiqizo, ukuze angathinti ikhwalithi yomkhiqizo.

 

Uyini umehluko phakathi kwezinto ze-Q235A ne-Q235B?

I-Q235A ne-Q235B zombili ziyinsimbi ye-carbon. Esilinganisweni sikazwelonke se-GB700-88, i-Q235A kanye ne-Q235B umehluko wezinto ezibonakalayo ikakhulukazi kokuqukethwe kwekhabhoni yensimbi, okokusebenza kokuqukethwe kwekhabhoni okubalulekile kwe-Q235A ku-0.14-0.22 ﹪ phakathi; Okubalulekile kwe-Q235B akwenzi ukuhlolwa komthelela, kodwa kuvame ukwenza ukuhlolwa komthelela wezinga lokushisa, i-V-notch. Uma kuqhathaniswa, izakhiwo zemishini yensimbi ye-Q235B zingcono kakhulu kunensimbi ye-Q235A. Ngokuvamile, umshini wokugaya insimbi kumaphrofayela aqediwe ngaphambi kokusuka embonini amakwa epuleti lokuhlonza. Abasebenzisi bangasho ukuthi ingabe okokusebenza kuyi-Q235A, Q235B, noma ezinye izinto ezisepuleti lokumaka.

 

Amabanga ensimbi yaseJapane yi-SPHC, SPHD, njll. Asho ukuthini?

Insimbi yaseJapane (uchungechunge lwe-JIS) amamaki ensimbi evamile yesakhiwo ngokuyinhloko iqukethe izingxenye ezintathu: ingxenye yokuqala ibonisa impahla, njengokuthi: S (Insimbi) isho insimbi, F (Ferrum) isho insimbi. Ingxenye yesibili yamajamo ahlukene, izinhlobo, ukusetshenziswa, okufana no-P (ipuleti) lelo puleti, T (ishubhu), K (kogu) lelo thuluzi. Ingxenye yesithathu yezimpawu zethebula zenombolo, ngokuvamile amandla amancane okudonsa. Okufana: ss400 - s lokuqala ukuthi insimbi (Steel), eyesibili s ukuthi "isakhiwo" (Structuree), 400 ngoba ephansi umugqa amandla 400Mpa ezejwayelekile steel kwesakhiwo. Phakathi kwazo: sphc ---- isifinyezo sokuqala se-Ssteel Steel, P sepuleti elithi Pate isifinyezo, H sesifinyezo sokushisa kokushisa, isifinyezo sezohwebo, konke kubonisa ukuthi umugqa ojwayelekile ogoqelwe oshisayo nowensimbi.

 

I-SPHD----- isho ishidi lensimbi eligoqiwe elishisayo kanye nomugqa wokugxiviza.

I-SPHE------ isho amashidi ensimbi agoqiwe ashisayo nemicu yokudweba okujulile.

I-SPCC------ isho ishidi lensimbi egoqiwe yekhabhoni ebandayo kanye nomugqa wokusetshenziswa okuvamile, okulingana nebanga laseChina Q195-215A. Uhlamvu lwesithathu C luyisifinyezo se-Cold, okudingekayo ukuze kuqinisekiswe ukuhlolwa kwe-tensile ekupheleni kwebanga kanye no-T we-SPCCT.

I-SPCD------ ikhombisa insimbi ye-carbon rolling ebandayo kanye nomugqa wensimbi wokubhobozwa, okulingana ne-China 08AL (13237) insimbi yekhwalithi ephezulu yekhabhoni yesakhiwo.

I-SPCE------ isho ishidi lensimbi egoqwe ngekhabhoni ebandayo kanye nomucu womdwebo ojulile, olingana nensimbi yokubhoboza yase-China 08AL (5213). Ukuze uqinisekise ukungasebenzi, engeza okuthi N ku-SPCEN ekupheleni kwebanga.

Ishidi lensimbi egoqiwe ye-carbon iron kanye ne-strip design, isimo esihlanganisiwe sika-A, izinga lokushisa elijwayelekile lika-S, 1/8 liqinile kokungu-8, 1/4 liqinile kokungu-4, 1/2 kanzima koku-2.

Ikhodi yokuqeda yobuso: akukho ukuqedwa kwesicwebezelisi ku-D, ukuqedela isicwebezelisi kwe-B. Okufana ne-SPCCT-SD ikhombisa izinga lokushisa elijwayelekile, alikho isicwebezelisi esiqeda ishidi lekhabhoni eligoqiwe elibandayo ukuze lisetshenziswe okuvamile. Bese i-SPCCT-SB ikhombisa ishidi lekhabhoni elipholile eliqinile, eliqedwe ngokugqamile, eligoqiwe elibandayo elinezakhiwo eziqinisekisiwe zokusebenza.
