ST52/45#/Q345/16Mn imibhobho yentsimbi engenamthungo

Iinkcukacha ngokukhawuleza:

Imibhobho yentsimbi engenamthungo yenziwe ngentsimbi engqukuva yonke enemingxuma. Imibhobho yentsimbi engenazo iintsimbi phezu komhlaba ibizwa ngokuba yimibhobho yentsimbi engenamthungo. Ngokwendlela yokuvelisa, imibhobho yentsimbi engenamthungo inokwahlulwa ibe yimibhobho yentsimbi engenamthungo eshushu-eqengqelekayo, imibhobho yentsimbi engenamthungo ebandayo, imibhobho yentsimbi ebandayo etsalwa ngokubanda, imibhobho yentsimbi engenamthungo, imibhobho ekhutshiweyo, njl. imilo, imibhobho yentsimbi engenamthungo yahlulwe ibe ziindidi ezimbini: ezijikelezileyo nezikhethekileyo. Imibhobho enemilo ekhethekileyo ineemilo ezahlukahlukeneyo ezintsonkothileyo ezinjengesikwere, umbhoxo, unxantathu, ihexagon, emile okwemelon, emile okwenkwenkwezi, kunye nemibhobho ephothiweyo. Ubukhulu bedayamitha yi-900mm kwaye ubuncinane bedayamitha yi-4mm. Ngokokusetyenziswa okwahlukeneyo, kukho imibhobho yentsimbi engenamthungo engqindilili kunye nemibhobho yentsimbi engenamthungo. Imibhobho yentsimbi engenamthungo isetyenziswa ikakhulu njengemibhobho yepetroleum yokomba yejoloji, imibhobho eqhekekileyo yoshishino lwepetrochemical, imibhobho yebhoyila, imibhobho ethwele, kunye nemibhobho yentsimbi yolwakhiwo oluchanekileyo ephezulu yeemoto, iitrektara, kunye nenqwelomoya.

Umbhobho wentsimbi we-Q345, owaziwa ngokuba yi-16Mn, i-16Mn umbhobho wentsimbi ongenamthungo yintsimbi eqhelekileyo ephantsi. Yintsimbi esetyenziswa ngokuqhelekileyo kwiibhoyili kunye neenqanawa zoxinzelelo. Ishushu iqengqeleke okanye iqhelekile. Yintsimbi ephantsi ye-alloy kunye nomxholo ophantsi we-Mn. Ukusebenza kufana ne-20G (412-540), amandla okuqina anamandla kancinane (450-655), kunye nobude be-19-21%, eyona nto imbi ngaphezu kwe-20G engaphezu kwe-24%.

I-16Mn ipayipi yensimbi engenamthungo yiplate ekhethekileyo yeenqanawa zoxinzelelo ezinamandla okuvelisa i-340MPa. Ineempawu ezilungileyo ezibanzi zoomatshini kunye nokusebenza kwenkqubo. Umxholo we-phosphorus kunye nesulfure ungaphantsi kancinci kunentsimbi eqhelekileyo ye-16Mn. Ukongeza kumandla okuqina kunye neemfuno zobude obuphezulu kunentsimbi eqhelekileyo eyi-16Mn, ukuqina kwempembelelo kuyafuneka ukuba kuqinisekiswe. Yeyona isetyenziswa kakhulu kwaye isetyenziswa ngokubanzi ipleyiti ekhethekileyo yentsimbi yeefestile zoxinzelelo kwilizwe lam.

45 # intsimbi: i-carbon content content yi-0.42-0.50%, umxholo we-silicon ngu-0.17-0.37%, umxholo we-manganese ophakathi ngu-0.50-0.80%, umxholo wesulfure ophakathi <=0.035%, umxholo we-phosphorus <=0.035%, umxholo we-chromium ophakathi <= 0.25%, umxholo we-nickel ophakathi <= 0.2545 intsimbi

inkcazo:

Imibhobho engenamthungo yenziwe ngeebhilithi zentsimbi ezingqukuva ezibethelwa embindini ukuze zenze iityhubhu ezingenanto ezithi ziqengqeleke okanye zikhutshelwe ngokomlinganiselo.

iinkcukacha:

Itheyibhile yokucacisa umbhobho ongenamthungo

lwezicelo:

Ifanelekile kwi-petroleum, i-aerospace, amandla ombane, ibhoyila, iikhemikhali kunye namanye amashishini.

Inzuzo Yokukhuphisana:

Umzi-mveliso wethu unezixhobo eziphambili zokuvelisa kunye neteknoloji, ekwazi ukuvelisa imibhobho yentsimbi engenamthungo yeenkcazo ezahlukeneyo kunye neemodeli. Umgangatho wemveliso uqinisekisiwe, iziteshi zokuthengisa zigudile, kwaye kukho iiyure ezi-7 * ezingama-24 emva kwenkonzo yokuthengisa ukuqinisekisa ngenkonzo emva kokuthengisa.
