Isikhokelo seNsimbi enamandla aphezulu: Ukusuka kwi-S355 ukuya kwi-S960 Grades

Kwihlabathi lobunjineli bezakhiwo, ukuhamba ngaphaya kwentsimbi yekhabhoni eqhelekileyo akusekho nto ibalulekileyo—kuyimfuneko yokusebenza nokuzinza. I-High Strength Steel, okanye i-HSS, ivumela uyilo oluthambileyo, ukunciphisa umthamo wokuwelda, kunye neendleko zothutho eziphantsi kakhulu.

Nangona kunjalo, iindlela zokubiza amagama zemigangatho yaseYurophu zihlala zibangela ukudideka evenkileni. Ukukhetha phakathi kwe-S460MLH kunye ne-S460NH akupheleli nje ekubhaleni ilebheli; kuyalawula indlela iprojekthi yakho eza kudityaniswa ngayo, yenziwe ngayo, kunye nendlela eza kusebenza ngayo kumaqondo obushushu angaphantsi kwe-zero.

Ixabiso lenani kulo naliphi na ibanga le-EN, elifana neli355okanye i-960, imele amandla amancinci esivuno alinganiswa kwii-megapascals. Nangona i-S355 isengumsebenzi wehlabathi jikelele wokwakha ngokubanzi, eli shishini litshintsha ngokukhawuleza liyeS460kunye ne-S690 ukuhlangabezana neenjongo zokonga ubunzima.

Impembelelo yokucubungula: M, N, kunye no-Q

Ileta elandela amandla ibonisa imeko yokuhanjiswa, nto leyo mhlawumbi yeyona nto ibalulekileyo ekwenzeni izinto.

• Uthotho lwe-M (oluqengqelekayo ngokwe-Thermomechanically):Ezi ntsimbi zicutshungulwa kumanqanaba athile obushushu ukuze zifumane amandla aphezulu kunye ne-carbon equivalents ephantsi kakhulu. Oku kwenza intsimbi yochungechunge lwe-M ibe lula kakhulu ukuyishibiliza, nto leyo edla ngokususa isidingo sokufudumeza kwangaphambili nakwiindawo ezityebileyo.
• Uthotho lwe-N (oluqhelekileyo):Indlela yendabuko apho intsimbi inyangwa ngobushushu ukuze kufunyanwe isakhiwo esifanayo sengqolowa. Izinzile kakhulu kwaye ikhethwa ukuba intsimbi iza kunyangwa ngobushushu okanye ifudumale ngexesha lokuveliswa.
• Uthotho lwe-Q (olucinyiweyo nolunomoya ophantsi):Lo ngumgangatho olungileyo wamandla aphezulu kakhulu. Ngokupholisa ngokukhawuleza size siphinde sifudumale intsimbi, sifumana amandla okuvelisa ukusuka kwi-690 MPa ukuya kwi-960 MPa. Nangona kunjalo, la manqanaba afuna ulawulo oluqinileyo lobushushu ngexesha lokuwelda ukuze kuthintelwe ukuthambisa izinto.

—–Ukubaluleka Kokuqina Kobushushu Obuphantsi————————————

Amandla ayisiqingatha sebali. Njengoko intsimbi isiba nzima, ngokwemvelo iba lula ukuba yaphuke kancinci. Ukuze kuliwe noku, iinjineli kufuneka zijonge amagama e-L okanye e-L1.

Amanqanaba aqhelekileyo ahlala eqinisekisa amandla ombane kwi -20°C. Ukuba iprojekthi yakho ijongene neendawo ezinzima—ezifana namaqonga aselunxwemeni, izixhobo eziphakamileyo, okanye iziseko ze-arctic—kufuneka uchaze i-MLH okanye i-NLH ukuze isebenze kwi -40°C, okanye i-QL1H ephezulu ukuze ithembeke ukuya kuthi ga kwi -60°C.

Ukusetyenziswa ngobuchule kwe-High Strength Stee

--FAQ----------

Umbuzo 1: Ngaba ndingayitshintsha ngqo i-S355 nge-S960 ukuze ndonge ubunzima?

A1: Akunjalo ngqo. Nangona i-S960 inamandla phantse kathathu, i-elastic modulus yentsimbi ihlala injalo. Ukuba uyilo lwakho luthintelwe "kukuphambuka" okanye "ukuqina" endaweni "yamandla," icandelo le-S960 elincinci lisenokungcangcazela okanye liguquguquke kakhulu. Kufuneka uyila kwakhona i-geometry ukuze usebenzise ngokupheleleyo amandla aphezulu.

Umbuzo 2: Kutheni i-S700MC yahlukile kwi-S690QH?

A2;Nangona amandla azo afana, i-S700MC yenzelwe ngokukodwa ukwakheka nokubanda nokugoba. Yipleyiti egoqwe ngobushushu (MC) enokusingatha imitha yokugoba eqinileyo ngaphandle kokuqhekeka, ngelixa iintsimbi ze-Q-series (QH) zilungiselelwe iindawo ezingenanto ezakhiweyo kunye neepleyiti ezinzima apho umthamo womthwalo onzima uphambili.

Umbuzo 3: Ngaba ukuwelda kuyayichaphazela amandla e-S960?

A4: Ewe. Iintsimbi ezinamandla kakhulu zixhomekeke kunyango oluchanekileyo lobushushu. Ukuba "ukufakwa kobushushu" kwe-welding kuphezulu kakhulu, kudala i-Softening Zone kwindawo ecaleni kwe-weld. Oku kunciphisa amandla endawo yejoyinti. Aba-welders kufuneka balandele iinkqubo ezingqongqo malunga namaqondo obushushu aphakathi kunye namazinga okupholisa.

Umbuzo 4: Ingaba kulula ukuwelda i-S460MLH kune-S460NH?

A4: Ngokubanzi, ewe. Ngenxa yokuba iiklasi ze-MLH zisebenzisa i-thermomechanical rolling, zifikelela kumandla azo ngezinto ezimbalwa zokudibanisa ezifana ne-carbon kunye ne-manganese. Le carbon equivalent isezantsi yenza intsimbi ingaqhekezeki kakhulu yi-hydrogen cracking, idla ngokuphelisa imfuneko yokufudumeza isinyithi ngaphambi kokuba sidibane.

Umbuzo 5: Imele ntoni i-“H” ekupheleni kwala mabanga?

A5: I-H imele iCandelo Elingenanto. Nokuba umbhobho yityhubhu ejikelezayo, enesikwere, okanye engxande, isimamva se-H siqinisekisa ukuba izinto ezisetyenzisiweyo ziyahlangabezana neemfuno ezithile zemigangatho ye-EN 10210 okanye ye-EN 10219 yamacandelo angenanto anesakhiwo.
