Intsimbi Q195, Q235, umahluko kwimpahla?

Nguwuphi umahluko phakathi kwe-Q195, Q215, Q235, Q255 kunye ne-Q275 ngokwemibandela?

I-carbon yesakhiwo se-carbon yesona sentsimbi esetyenziswayo, elona nani liphezulu lentsimbi liqengqeleka kwintsimbi, iiprofayili kunye neeprofayili, ngokubanzi akufuneki ukuba zisetyenziswe ngobushushu, ubukhulu becala kubuchwephesha ngokubanzi kunye nobunjineli.

I-Q195, Q215, Q235, Q255 kunye ne-Q275, njl., Njl njl. , B, C, D) Indlela ye-Deoxygenation yeesimboli kunye neinxalenye ezine zokubekwa ngokulandelelana. Ukusuka kubume bemichiza, amabakala ensimbi ye-Q195, Q215, Q255, Q255 iBanga elikhulu, umxholo wekhabhoni, owona mxholo wayo weplanga. Iipropathi zoomatshini kumanqaku, la manqanaba angasentla abonisa ukuba ubukhulu ≤ 16mm wesivuno sentsimbi yentsimbi. Amandla ayo angamathondi kukuba: 315-430, 335-450, 410-550, 490-630 (i-Abn / mm / mm2); I-QI ye-eloutyation yayi: 33, 31, 26, 24, 20, 20 (0.5%). Ke ngoko, xa ukwazisa intsimbi kubathengi, abathengi kufuneka bakhunjuzwe ukuba bathenge izixhobo ezahlukileyo zentsimbi ngokwezixhobo zemveliso eziyimfuneko, ukuze zingachaphazeli umgangatho wemveliso.

 

Nguwuphi umahluko phakathi kwe-Q235A kunye ne-Q235b yezixhobo?

I-Q235A kunye ne-Q235B zezibini zekhabhoni zombini. Kwinqanaba leSizwe leSizwe le-GB700-88, Q23A kunye ne-Q235B kunye ne-Q235b yezinto ezibonakalayo ikakhulu ikwi-carbon yomxholo wensimbi kwi-0.14-0.22% phakathi; I-Q235b impahla ayisebenzi uvavanyo lwempembelelo, kodwa ihlala iluvavanyo lweqondo lobushushu, i-notch. Ngokuthetha ngokuthelekisa, iipropathi zoomatshini be-Q235b yentsimbi ilunge ngakumbi kune-Q235A yentsimbi. Ngokubanzi, inyibiba yentsimbi kwiiprofayili ezigqityiweyo ngaphambi kokuba ihambe umzi-mveliso iphawulwe kwiplate yokuchonga. Abasebenzisi banokuxelela ukuba izinto ze-Q235a, Q235B, okanye ezinye izinto kwiplate yokumakisha.

 

Amanqanaba ensizi yaseJapan ayi-SPHC, i-SPHD, njl. Zithetha ntoni?

I-Japan yensimbi (Jis) Amabakala ensimbi yesiqhelo equkethe iinxalenye ezintathu: Icandelo lokuqala libonisa izinto, ezinje: S (Ferrum) kuthetha intsimbi. Inxalenye yesibini yeemilo ezahlukileyo, iindidi, ukusetyenziswa, ezinje nge p (ipleyiti) yelo pile, t (ityhubhu), k (kou) eso sixhobo. Inxalenye yesithathu yeempawu zetafile zenani, ngokubanzi amandla amanye amanqindi. Enje nge: I-SS400 - eyokuqala yentsimbi (i-SSTEEL), yesibini ye-SAY "ye-SAPLOS" (iMation "(400 yamandla asezantsi e-400MPA eqhelekileyo yentsimbi. Phakathi kwawo: I-SPHC ---- i-Ssteel Steef Steef, P kwiPlate Gate Isifinyezo, H ngenxa yobushushu obushushu, i-stereds, yonke ibonisa ukuba umtya oshushu oshushu oshushu kunye nentsimbi.

 

I-SPHD ----- ibonisa iphepha lentsimbi elishushu kunye nomtya wokuzibetha.

I-SPhe ------ ibonisa amaphepha entsimbi eshushu kunye nemigca yomzobo onzulu.

I-SPCC ------ ibonisa i-Carbon ye-Carbon Steel kunye nomtya wokusetyenziswa jikelele, ukufana ne-China Q195-21Abanga. Unobumba wesithathu C sisifinyezo sokubanda, ekufuneka ukuqinisekisa uvavanyo lwe-tednsle ekupheleni kwenqanaba le-T le-tcct.

I-SPCD ---- ibonisa ukubanda i-carbon steel kunye nentsimbi yentsimbi ye-punch, ilingana ne-China 08al (13237) Intsimbi ephezulu ye-carbon.

I-SPCE ---- Ukuqinisekisa ukungasebenzi, ukongeza n ukuya ekupheleni kwebakala.

Iphepha elibandayo le-carbon eliqengqelekayo kunye nokuchongwa komtya, imeko enesiseko se-S, 1/8 i-S, 1/8 inobunzima kwi-8, 1/4 nzima kwi-4, 1 ye-2.

Ikhowudi yokuGqibela engaphaya: Ngaphandle kokugqitywa kwe-D, ukugqitywa kwe-B. Emva koko i-SPCTCT-SB ibonisa ukuba inomgangatho osemngciphekweni, igqitywe ngephepha eliqaqambileyo lekhabhoni eqingqiweyo eneempawu eziqinisekisiweyo zoomatshini.
