I-Alloy yaManzi eQonxiweyo eHotsiweyo Isikhongozelo seTanki saManzi esiSetyenzisiweyo seBoiler Plate yentsimbi A516-70
I-Q460 yintsimbi ene-alloy-high-high-low-alloy steel.Indlela yokutyunjwa kwe-Q460: inombolo yayo yentsimbi ifakwe kwi-"Q", emele isivuno sentsimbi, oko kukuthi, amandla okuvelisa.Inombolo elandelayo ibonisa ukuba ixabiso lexabiso lesivuno 460 limele i-460 MPa, i-mega yi-6 yamandla e-10, kunye ne-Pa yiyunithi yoxinzelelo uPascal.I-Q460 ithetha ukuba i-deformation yeplastiki yensimbi iya kwenzeka kuphela xa amandla ensimbi efikelela kwi-460 MPa, oko kukuthi, xa kukhutshwa amandla angaphandle, insimbi inokugcina imo egxininisiweyo kwaye ayikwazi ukubuyela kwimo yayo yangaphambili.La mandla makhulu kunentsimbi eqhelekileyo.Iisimboli zomgangatho oqhelekileyo ngu-A, B, C, D, E, ngokulandelelanayo.Ngesiseko sokuqinisekisa ukulingana kwekhabhoni ephantsi, i-Q460 ngokufanelekileyo yandisa umxholo wezinto ezincinci ze-microalloying.Ukusebenza kakuhle kwe-welding kufuna ukulingana kwekhabhoni ephantsi yentsimbi, kwaye ukwanda kwezinto ezincinci ze-microalloying kwandisa amandla entsimbi ngelixa kwandisa i-carbon elingana nentsimbi.Kodwa ngethamsanqa, ukulingana kwekhabhoni okongeziweyo kuncinci, ngoko akuyi kuchaphazela ukusebenza kwe-welding yentsimbi.
Uphuhliso olukhawulezayo lweshishini leemoto ludlale indima ebalulekileyo kuphuhliso lwezoqoqosho nentlalontle yesizwe.Nangona kunjalo, ngenxa yempembelelo yokunqongophala kwamandla, ungcoliseko lwendalo kunye nezinye iingxaki, ukuphikisana kuphuhliso lweshishini kuye kwanda kakhulu.Ukukhangela phambili kwikamva, uphuhliso lweshishini lunokugcinwa kuphela ukuba lusekelwe kwimvelaphi yendalo, i-ecology, ukugcinwa kwamandla kunye nokhuseleko.
Ngaphantsi kwale mvelaphi, ukusetyenziswa kwemoto ekhaphukhaphu kunye nentsimbi ephezulu ibe lukhokelo olubalulekileyo lophuhliso.Nangona kunjalo, ngokuphuculwa kwamandla eplate yentsimbi ephezulu, inkqubo yesitampu ebandayo yendabuko ijwayele ukuphuka kwindlela yokwenza, engakwaziyo ukuhlangabezana neemfuno zokucwangcisa ipleyiti yensimbi ephezulu.Kule meko, itekhnoloji eshushu yokwenza isitampu yentsimbi yentsimbi ephezulu iye yafundwa ngokuthe ngcembe kwihlabathi - inkqubo entsha yokudibanisa ukwenza, ukuhanjiswa kobushushu kunye nokuguqulwa kwe-microstructure, esetyenziswa ikakhulu iimpawu zokwanda kweplastikhi kunye nokunciphisa amandla emveliso yephepha. isinyithi kwimeko yobushushu obuphezulu austenite.Nangona kunjalo, i-thermoforming ifuna uphando olunzulu malunga neemeko zenkqubo, ukuguqulwa kwesigaba sesinyithi kunye neteknoloji yohlalutyo lwe-CAE, kodwa obu bugcisa bulawulwa ngabavelisi bangaphandle kwaye bukhula kancinci e-China.
Ngokutsho kophando kunye neenkcukacha-manani, ukusetyenziswa kwentsimbi ephezulu yezinye iimpawu zemoto kuyanda, kwaye ukusetyenziswa kwentsimbi ephezulu yesakhelo somzimba weminye imodeli ifikelele kwi-90%.Ngokutsho kophando lwesebe lamandla le-American Iron and Steel Institute, nokuba ixabiso lentsimbi ephezulu liyancipha, ukunyanzeliswa kwayo kunzima kakhulu kunepleyiti ebandayo yendabuko.I-ductility yensimbi ephezulu yokuqina isiqingatha kuphela sentsimbi eqhelekileyo.
Xa izinto zenziwe ngokunyathela, ziya kuba nzima.Iintsimbi ezahlukeneyo zinemigangatho eyahlukeneyo yokuqina.Ngokubanzi, amandla aphezulu entsimbi yealloy ephantsi yonyuka kancinci nge-20MPa, ngaphantsi kwe-10%.Qaphela: amandla okuvunwa kwentsimbi ye-double phase anyuke nge-140 MPa, ukwanda okungaphezulu kwe-40%!Ngethuba lenkqubo yokwenza, isinyithi siya kuba sahluke ngokupheleleyo, ngokungafaniyo ngokupheleleyo nangaphambi kokuba inkqubo yesitampu iqale.Ukomelela kwesivuno kwezi ntsimbi kwandisa kakhulu emva koxinzelelo.Uxinzelelo oluphezulu lwesivuno sezinto ezidityaniswe nokuqina komsebenzi lilingana nokunyuka okubalulekileyo koxinzelelo lokuhamba.Ke ngoko, ukuqhekeka, i-springback, ukushwabana, ubungakanani bomsebenzi, ukunxitywa kokufa kunye nokunxiba kwe-welding encinci kuye kwaba yingqwalasela yeengxaki kwinkqubo yokwenziwa kwentsimbi ephezulu.
Ngokusekelwe kwiimpawu kunye neempawu zentsimbi ephezulu, ukuba ukuhamba kwesinyithi akunakutshintshwa kwaye ukungqubuzana akunakuncitshiswa, ukuchithwa kunye nokuthungwa okungalinganiyo kwentsimbi ephezulu (HSS) kunokukhokelela ekunyuseni kwinqanaba le-scrap yecandelo.Amandla ekhiloponti ephezulu nge-intshi nganye yesikwere (i-Ksi) yesi sixhobo (iyunithi yokulinganisa amandla esivuno), ukomelezwa kokubuyela umva, utyekelo lokuqina lomsebenzi kunye nokusebenza kwiqondo lobushushu elinyukileyo yonke imicelimngeni yokufa.
