Iphepha lentsimbi le-ASTM SA283GrC/Z25 lifike likwimeko eshushu eqengqelekayo SA283GrC Imeko yokuhanjiswa:
Imeko yokuhanjiswa kwe-SA283GrC: Ngokubanzi xa ishushu kakhulu xa ihanjiswa, imeko yokuhanjiswa kwayo kufuneka iboniswe kwiwaranti.
Ixabiso loluhlu lwemixube yeekhemikhali ye-SA283GrC: Qaphela: Ulwakhiwo lwekhemikhali olukwiwaranti yefektri yentsimbi luya kusebenza.
Ikhabhoni C: ≤0.24 Si: (ipleyiti yentsimbi ≤40) ≤0.40 (ipleyiti yentsimbi > 40) 0.15-0.40
IManganese Mn: ≤0.90 I-Sulfur S: ≤0.040 I-Phosphorus P: ≤0.035
I-Copper Cu: 0.20 okanye ngaphantsi
Ipleyiti yentsimbi ye-SA283GrC ifanelekile kwizakhiwo ze-riveting, bolting kunye ne-welding kwiiBridges nakwizakhiwo. Yintsimbi yesakhiwo sekhabhoni esetyenziswa ngokubanzi enomgangatho wentsimbi yesakhiwo.
Imeko yokuhanjiswa kwepleyiti yentsimbi ye-SA283GrC: ukuqengqeleka okushushu, ukuqengqeleka okulawulwayo, imeko eqhelekileyo yokuhanjiswa
Izinto zokwakha ipleyiti yentsimbi ye-SM400ZL yesithando somlilo:
I-SM400ZL yipleyiti yentsimbi esemgangathweni yaseJapan ene-alloy ephezulu enamandla aphantsi kwigobolondo le-converter. Lo mgangatho uchaza ubungakanani, imo, iimfuno zobugcisa, iindlela zovavanyo, imithetho yokuhlolwa, ukupakishwa, iimpawu kunye nezatifikethi zomgangatho weepleyiti zentsimbi ze-blast furnace, i-converter kunye neegobolondo ze-hot blast furnace. Isebenza kwipleyiti yentsimbi yegobolondo le-furnace enobukhulu obuyi-8mm ~ 200mm. Ukuphambuka kobukhulu obungalunganga kwipleyiti yentsimbi ye-SM400ZL kunqunyelwe kwi--0.25mm, kwaye indawo yokunyamezela ubukhulu kufuneka ihambelane ne-GB/T709.
Uluhlu lwepleyiti yentsimbi ye-S355NL [ubukhulu obuyi-8-200] yokusika, uluhlu lwezinto:
Umgangatho ophezulu we-S355NL: EN10025-3: igama elipheleleyo: ukulungisa/ukulungisa ipleyiti yesinyithi yesakhiwo sengqolowa eyosiweyo egoqwe kakuhle. Lo mgangatho kunye ne-EN10025-1 kunye zithatha indawo ye-EN 10113-1:1993 iimveliso zesinyithi zengqolowa eyosiweyo egoqwe kakuhle eshushu Icandelo I: Iimeko eziqhelekileyo kunye ne-EN 10113-2:1993 iimveliso zesinyithi zengqolowa eyosiweyo eshushu egoqwe kakuhle eshushu Icandelo II: ukulungisa/ukulungisa iimeko zesinyithi ezigoqwe kakuhle. Xa ubushushu bomgangatho bungekho ngaphantsi kwe-20 ° C, ixabiso elincinci lamandla empembelelo akhankanyiweyo libonakaliswa kwi-N; xa ubushushu bungekho ngaphantsi kwe-50 ° C, ixabiso elincinci lamandla empembelelo akhankanyiweyo libonakaliswa kwi-NL.
2. Intsingiselo ehambelanayo yeleta yepleyiti yentsimbi ye-S355NL:
S: intsimbi yesakhiwo, N: ilizwe, inkunzi L: inqanaba lamandla empembelelo aphantsi akhankanyiweyo xa ubushushu bungekho ngaphantsi kwe - 50 ° C
Ipleyiti yentsimbi ye-S355ML [ubude obuyi-8-200mm] ukuqengqeleka kwe-thermomechanical
Ipleyiti yentsimbi ye-S355ML ihanjiswa ikwimeko yokuqengqeleka koomatshini abashushu
Iimfuneko zoKwakhiwa kweeKhemikhali ze-S355ML
C:≤0.14,Si:≤0.5,Mn:≤1.6,P:≤0.025,S:≤0.02,Nb:≤0.05,V:≤0.1,A 1
Ipleyiti yentsimbi ye-S355ML yintsimbi yokwakha egoqwe kakuhle enyibilikiswayo eshushu, eyinxalenye yoluhlu lweepleyiti zentsimbi ezinamandla aphezulu. Yimveliso egoqwe ngokuthe tyaba enobukhulu obungadluli kwi-120mm kunye nemveliso ende enobukhulu obungadluli kwi-150mm. I-S ithetha intsimbi yokwakha, i-355 ibonisa ukuba ixabiso elincinci lemveliso yobukhulu obufanelekileyo obungaphantsi kwe-16mm yi-355MPa, kwaye i-M imele ukuhanjiswa kwayo, oko kukuthi, ukuqengqeleka okushushu. Umthetho kukuba impembelelo kubushushu obungadluli kwi--50 degrees iboniswa ngonobumba omkhulu u-L. I-S355 yintsimbi yokwakha engeyiyo i-alloy.
Ububanzi bokusetyenziswa kwepleyiti yentsimbi ye-S355ML
Ukongeza kwintsimbi ye-EN10,025-1, isicwangciso sentsimbi esichazwe ngokukodwa kulo mgangatho sikwasetyenziswa kwiindawo ezithwala umthwalo zezakhiwo ezidityanisiweyo ezisetyenziswa ngeenxa zonke zeebhulorho, iindawo zokuqubha, iitanki zokugcina, iitanki zokuhambisa amanzi, njl.njl. kunye nobushushu obuphantsi.
