Insimbi Q195, Q235, umehluko ezintweni ezibonakalayo?

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

Insimbi yesakhiwo sekhabhoni yinsimbi esetshenziswa kakhulu, inani elikhulu kunawo wonke avame ukugoqwa abe yinsimbi, amaphrofayili namaphrofayili, ngokuvamile akudingeki ukuthi isetshenziswe ngqo ngokushisa, ikakhulukazi ngesakhiwo esijwayelekile kanye nobunjiniyela.

I-Q195, Q215, Q235, Q255 kanye ne-Q275, njll., ngokulandelana, ikhombisa izinga lensimbi, izinga lensimbi ngummeleli wephuzu lokukhiqiza lencwadi (Q), inani lephuzu lokukhiqiza, ikhwalithi, ikhwalithi kanye nezinye izimpawu (A, B, C, D) zezimpawu nokunye izingxenye ezine zokwakheka okulandelanayo. Kusukela ekwakhiweni kwamakhemikhali, amazinga ensimbi athambile Q195, Q215, Q235, Q255 kanye namazinga e-Q275 amakhulu, okuqukethwe kwekhabhoni kuphakeme, okuqukethwe kwe-manganese, kulapho i-plasticity yayo izinzile khona. Izakhiwo zemishini ezivela emaphuzwini, amazinga angenhla abonisa ukuthi ukujiya ≤ 16mm kwephuzu lokukhiqiza lensimbi. Amandla ayo okudonsa ayengu: 315-430, 335-450, 375-500, 410-550, 490-630 (obN/mm2); ukwandiswa kwayo kwakuyi: 33, 31, 26, 24, 20 (0.5%). Ngakho-ke, lapho wethula insimbi kumakhasimende, amakhasimende kufanele akhunjuzwe ukuthi athenge izinto ezahlukene zensimbi ngokwezinto zomkhiqizo ezidingekayo, ukuze kungathinti ikhwalithi yomkhiqizo.

 

Uyini umehluko phakathi kwezinto ze-Q235A ne-Q235B?

I-Q235A kanye ne-Q235B zombili ziyinsimbi yekhabhoni. Ku-GB700-88 ejwayelekile kazwelonke, umehluko wezinto ze-Q235A kanye ne-Q235B ugxile kakhulu kokuqukethwe kwekhabhoni kwensimbi, izinto zokuqukethwe kwekhabhoni yezinto ze-Q235A ku-0.14-0.22 ﹪ phakathi; izinto ze-Q235B azenzi ukuhlolwa komthelela, kodwa zivame ukwenza ukuhlolwa komthelela wokushisa, i-V-notch. Uma kuqhathaniswa, izakhiwo zomshini zensimbi ye-Q235B yezinto zingcono kakhulu kunensimbi ye-Q235A yezinto. Ngokuvamile, umshini wensimbi kumaphrofayili aqediwe ngaphambi kokushiya ifektri ubhalwe epuletini lokuhlonza. Abasebenzisi bangabona ukuthi impahla yi-Q235A, Q235B, noma ezinye izinto epuletini lokumaka.

 

Amamaki ensimbi aseJapan yi-SPHC, SPHD, njll. Asho ukuthini?

Izinsimbi zaseJapane (uchungechunge lwe-JIS) zensimbi evamile yokwakha ikakhulukazi ziqukethe izingxenye ezintathu: ingxenye yokuqala ikhombisa izinto ezibonakalayo, njengokuthi: S (Insimbi) isho insimbi, F (Ferrum) isho insimbi. Ingxenye yesibili yezimo ezahlukene, izinhlobo, ukusetshenziswa, njenge-P (ipuleti) lelo plate, T (ithubhu), K (kogu) lelo thuluzi. Ingxenye yesithathu yezimpawu zethebula lenombolo, ngokuvamile amandla amancane okunamathela. Njenge: ss400 - owokuqala s ukuthi insimbi (Insimbi), owesibili s ukuthi "isakhiwo" (Isakhiwo), 400 ngamandla omugqa ophansi wensimbi evamile yokwakha engu-400Mpa. Phakathi kwazo: sphc ---- isifinyezo sokuqala se-Ssteel Steel, P sepuleti isifinyezo se-Pate, H sokushisa Isifinyezo sokushisa, Isifinyezo sezentengiselwano, konke kubonisa ukuthi umucu ojwayelekile ogoqwe ngokushisa kanye nensimbi.

 

I-SPHD----- imelela ishidi lensimbi eligoqiwe elishisayo kanye nomcu wokufaka isitembu.

I-SPHE------ imelela amashidi ensimbi asongwe ashisayo kanye nemichilo yokudweba okujulile.

I-SPCC------ imelela ishidi lensimbi yekhabhoni eligoqiwe elibandayo kanye nomcu wokusetshenziswa okuvamile, okulingana nebanga laseShayina Q195-215A. Uhlamvu lwesithathu u-C luyisifinyezo se-Cold, esidingekayo ukuqinisekisa ukuhlolwa kokuqina ekugcineni kwebanga kanye no-T we-SPCCT.

I-SPCD------ ikhombisa insimbi yekhabhoni egoqiwe ebandayo kanye nomcu wensimbi wokubhoboza, okulingana nensimbi yokwakha yekhabhoni yekhwalithi ephezulu yase-China 08AL (13237).

I-SPCE------ imelela ishidi lensimbi yekhabhoni eligoqiwe elibandayo kanye nomcu wokudweba okujulile, okulingana nensimbi yokubhoboza yaseChina 08AL (5213). Ukuqinisekisa ukungasebenzi kahle, engeza u-N ku-SPCEN ekupheleni kwebanga.

Ishidi lensimbi yekhabhoni eligoqiwe elibandayo kanye nencazelo yomugqa, isimo esifakwe i-A, esijwayelekile esithambile ku-S, 1/8 eqinile ku-8, 1/4 eqinile ku-4, 1/2 eqinile ku-2.

Ikhodi yokuqeda ubuso: akukho ukuqedwa okucwebezelayo kuka-D, ukuqedwa okucwebezelayo kuka-B. Njenge-SPCCT-SD isho ishidi lekhabhoni eligoqiwe elibandayo elijwayelekile, elingenalo ukuqedwa okucwebezelayo lokusetshenziswa okuvamile. Bese i-SPCCT-SB isho ishidi lekhabhoni eligoqiwe elijwayelekile, eliqediwe ngokukhanyayo, eligoqiwe elibandayo elinezakhiwo eziqinisekisiwe zemishini.
