Intsimbi Q195, Q235, umahluko kwizinto eziphathekayo?

Yintoni umahluko phakathi kwe-Q195, Q215, Q235, Q255 kunye ne-Q275 ngokwezinto ezisetyenzisiweyo?

Intsimbi yesakhiwo sekhabhoni yeyona ntsimbi isetyenziswa kakhulu, uninzi lwayo luhlala luqengqeleka lube yintsimbi, iiprofayili kunye neeprofayili, ngokubanzi akufuneki zisetyenziswe ngqo ngobushushu, ikakhulu kwisakhiwo ngokubanzi kunye nobunjineli.

I-Q195, i-Q215, i-Q235, i-Q255 kunye ne-Q275, njl., ngokulandelelana, zibonisa umgangatho wentsimbi, umgangatho wentsimbi ngummeli wenqaku lemveliso yonobumba (Q), ixabiso lenqaku lemveliso, umgangatho, umgangatho kunye nezinye iimpawu (A, B, C, D) zeempawu kunye nezinye iindawo ezine zokwakheka okulandelelanayo. Ukusuka kulwakhiwo lweekhemikhali, amanqaku entsimbi ethambileyo i-Q195, i-Q215, i-Q235, i-Q255 kunye ne-Q275 amanqanaba amakhulu, okukhona umxholo wekhabhoni uphezulu, umxholo we-manganese, kokukhona uzinzo lweplastiki yayo. Iimpawu zoomatshini ezivela kumanqaku, amanqanaba angentla abonisa ukuba ubukhulu ≤ 16mm benqaku lemveliso yentsimbi. Amandla ayo okutsalwa yayiyi: 315-430, 335-450, 375-500, 410-550, 490-630 (obN/mm2); ukwandiswa kwayo bekuyi: 33, 31, 26, 24, 20 (0.5%). Ke ngoko, xa besazisa intsimbi kubathengi, abathengi kufuneka bakhunjuzwe ukuba bathenge izinto ezahlukeneyo zentsimbi ngokwezinto ezifunekayo zemveliso, ukuze bangachaphazeli umgangatho wemveliso.

 

Yintoni umahluko phakathi kwezinto ze-Q235A kunye ne-Q235B?

I-Q235A kunye ne-Q235B zombini ziintsimbi yekhabhoni. Kwi-GB700-88 esemgangathweni kazwelonke, umahluko wezinto ze-Q235A kunye ne-Q235B ngokuyintloko ukwimeko yekhabhoni yentsimbi, izinto ze-Q235A umxholo wekhabhoni kwi-0.14-0.22 ﹪ phakathi; izinto ze-Q235B azenzi uvavanyo lwempembelelo, kodwa zihlala zenza uvavanyo lwempembelelo yobushushu, i-V-notch. Ngokuthelekisa, iipropati zoomatshini zentsimbi ye-Q235B zingcono kakhulu kunentsimbi ye-Q235A. Ngokubanzi, i-mill yentsimbi kwiiprofayili ezigqityiweyo ngaphambi kokuba iphume kumzi-mveliso iphawulwe kwipleyiti yokuchonga. Abasebenzisi banokubona ukuba izinto ze-Q235A, Q235B, okanye ezinye izinto kwipleyiti yokuphawula.

 

Iiklasi zentsimbi zaseJapan ziyi-SPHC, i-SPHD, njl. Zithetha ukuthini?

Iiklasi zentsimbi yaseJapan (uthotho lweJIS) zentsimbi eqhelekileyo yolwakhiwo ikakhulu ziqulathe iindawo ezintathu: inxalenye yokuqala ibonisa izinto, ezifana nezi: S (Intsimbi) ithetha intsimbi, F (Ferrum) ithetha intsimbi. Inxalenye yesibini yeemilo ezahlukeneyo, iintlobo, ukusetyenziswa, ezifana ne-P (ipleyiti) loo pleyiti, T (ityhubhu), K (kogu) loo sixhobo. Inxalenye yesithathu yeempawu zetafile yenani, ngokubanzi amandla amancinci okutsalwa. Ezifana nezi: ss400 - eyokuqala s ukuba intsimbi (Intsimbi), eyesibini s ukuba "isakhiwo" (Isakhiwo), 400 yamandla omgca osezantsi wentsimbi eqhelekileyo yolwakhiwo ye-400Mpa. Phakathi kwazo: sphc ---- eyokuqala sphc Intsimbi yesifinyezo, P yepleyiti strip Pate, H yobushushu strip Ubushushu, strip yorhwebo, yonke ibonisa ukuba strip eshushu nentsimbi ngokubanzi.

 

I-SPHD----- ibonisa ishidi lesinyithi eligoqiweyo elishushu kunye nomcu wokunyathela.

I-SPHE------ ibonisa amaphepha entsimbi asongiweyo ashushu kunye nemicu yokuzoba nzulu.

I-SPCC------ imela iphepha lesinyithi lekhabhoni eligoqiweyo elibandayo kunye nomcu wokusetyenziswa ngokubanzi, olingana nomgangatho we-China Q195-215A. Unobumba wesithathu u-C sisifinyezo se-Cold, esifunekayo ukuqinisekisa uvavanyo lokuxinana ekupheleni komgangatho kunye no-T we-SPCCT.

I-SPCD------ ibonisa intsimbi yekhabhoni eqengqelekayo ebandayo kunye nomcu wentsimbi wokubhoboza, olingana nentsimbi yokwakha yekhabhoni ekumgangatho ophezulu yaseTshayina 08AL (13237).

I-SPCE------ ibonisa ishidi lesinyithi sekhabhoni esigoqiweyo esibandayo kunye nomcu wokuzoba nzulu, olingana nentsimbi yokubhoboza yaseTshayina 08AL (5213). Ukuqinisekisa ukuba ayisebenzi, yongeza i-N kwi-SPCEN ekupheleni komgangatho.

Iphepha lesinyithi lekhabhoni eligoqiweyo kunye nophawu lwestrip, imeko efakwe kwi-A, i-standard tempered kwi-S, i-1/8 eqinileyo kwi-8, i-1/4 eqinileyo kwi-4, i-1/2 eqinileyo kwi-2.

Ikhowudi yokugqiba umphezulu: akukho kugqitywa kwe-gloss ku-D, ukugqitywa kwe-gloss ku-B. Njenge-SPCCT-SD ibonisa ishiti yekhabhoni eqinisiweyo eqhelekileyo, engenakugqitywa kwe-gloss ebandayo yokusetyenziswa ngokubanzi. Emva koko i-SPCCT-SB ibonisa ishiti yekhabhoni eqinisiweyo eqhelekileyo, egqityiweyo ngokukhazimlayo, eqhotsiweyo ebandayo eneempawu zoomatshini eziqinisekisiweyo.
