Fumana iimfihlo zemibhobho edityanisiweyo ephezulu

Kwinsimbi yanamhlanje yezoshishino, enye into ivelele njengomqolo wokwakhiwa kobunjineli ngenxa yeempawu zayo ezicacileyo-iipayipi zensimbi ze-Q345, ezinikezela ukulingana okugqibeleleyo kwamandla, ukuqina, kunye nokusebenza.

 

I-Q345 yintsimbi ye-alloy ephantsi, eyayibizwa ngokuba yi-16Mn. I "Q" ekutyunjweni kwayo imele amandla esivuno, ngelixa "345" ibonisa ubuncinci amandla okuvelisa i-345 MPa kwiqondo lokushisa. Ihambelana nomgangatho we-GB / T 1591-2008, ifumana isicelo esibanzi kwiibhulorho, izakhiwo, izithuthi, iinqanawa, iinqanawa zoxinzelelo kunye neeprojekthi zobunjineli be-cryogenic. Ngokuqhelekileyo inikezelwa kwiimeko ezishushu okanye eziqhelekileyo.

 

Ukuhambelana kwintsebenzo yokucubungula enye inzuzo enkulu yeepayipi zensimbi ze-Q345. Umxholo wayo ophantsi wekhabhoni (ngokuqhelekileyo ≤0.20%) kunye nokwakhiwa kwe-alloy ephuculweyo kuqinisekisa ukuwelda okugqwesileyo. Nokuba usebenzisa i-welding ye-arc yensimbi ye-manual, i-arc ye-arc efakwe emanzini, okanye i-welding ekhuselwe yigesi, i-welding ezinzile kunye nezithembekileyo ezidibeneyo zinokufezekiswa, ukuhlangabezana neemfuno ezinzima zokwakhiwa kwendawo. Ukongeza, iipropathi zayo eziphezulu zokubanda kunye nokusebenza okushushu zivumela ukwenziwa kwizinto ezahlukeneyo ezimile ngeenkqubo ezinje ngokuqengqeleka, ukugoba, kunye nesitampu, ezibandakanya uyilo lobunjineli olwahlukeneyo.

 

I-Application Landscape: Ukusuka kwi-Landmark Structures ukuya kwi-Energy Infrastructure, i-Q345 imibhobho yentsimbi iye yangena kuwo onke amacandelo oshishino lwangoku. Kulwakhiwo kunye nobunjineli bebhulorho, baxhasa ubume bezakhiwo ze-skyscrapers kwaye basebenza njengeebhanti eziphambili zeebhulorho ezijikeleza umlambo, besebenzisa amandla abo aphezulu ukunciphisa ubunzima besakhiwo ngelixa bemelana ne-seismic kunye nemithwalo ephezulu yomoya ngokuqina okuphuculweyo. Izixhobo zoomatshini bobunjineli kunye nezakhelo, iishafti zokuqhuba isithuthi esinzima, kunye neekholamu zebhedi yesixhobo somatshini zonke zifuna izinto ezidibanisa amandla kunye nokumelana nokudinwa. Ngokuzoba okubandayo kunye neenkqubo zokwandisa okushushu, imibhobho yentsimbi ye-Q345 ihlangabezana ngokuchanekileyo neemfuno zoomatshini zamacandelo ahlukeneyo, ukwandisa ixesha lokuphila kwezixhobo. Ukusetyenziswa kwamandla kunye nemibhobho—njengemibhobho yothumelo lwe-oyile nerhasi, amanzi asezidolophini kunye nothungelwano lokufudumeza, kunye nemibhobho yokufudumeza ephezulu kwizibiyeli zeplanti yamandla—izinto ezifunekayo mazimelane noxinzelelo lwangaphakathi kunye nomhlwa wangaphandle. Imibhobho yentsimbi ye-Q345, ephathwa ngokukhuselwa komhlwa (umzekelo, ukupeyinta, ukugalela intsimbi), iqinisekisa ukusebenza okuzinzile kwexesha elide kwiindawo ezifumileyo, ezinothuli, okanye ezinokonakalisa kancinci, zikhusela uthutho lwamandla olukhuselekileyo nolusebenzayo.

 

Ingqinisekiso yeNkqubo:Ukuzibophelela koMgangatho ukusuka kwi-Ingot ukuya kwiMveliso egqityiweyo Ukudalwa kwe-premium Q345 imibhobho yensimbi ixhomekeke kulawulo oluchanekileyo lwenkqubo yokuvelisa. Imibhobho engenamthungo igqojozwa, iqengqeleke, kwaye ilinganiswe ukuqinisekisa ubukhulu bodonga olufanayo kunye nokuchaneka komda. Imibhobho edityanisiweyo yenziwe nge-high-frequency okanye i-arc welding ephantsi kwamanzi, elandelwa luvavanyo olungonakalisi kunye noxinzelelo lokunciphisa unyango lobushushu ukuze kupheliswe iingozi ezinokubakho ngexesha lokusetyenziswa. Wonke umbhobho wensimbi we-Q345 ofanelekileyo uhlolwa ngeendlela ezininzi-kubandakanywa novavanyo lwe-tensile, iimvavanyo zempembelelo, kunye nemilinganiselo yobunzima-ukuqinisekisa ukuthotyelwa kokusebenza.

 

Iintsingiselo zexesha elizayo:Indlela yoHlaza kunye neNtsha eqhutywayo yokuPhucula

Iqhutywa kukuqhubela phambili kweenjongo "zekhabhoni ezimbini" kunye nemfuno ekhulayo yokukhanya kweshishini, imibhobho yentsimbi ye-Q345 iguqukela ekusebenzeni kakuhle kunye nokuzinza kwendalo. Kwelinye icala, ngobuchule obuphuculweyo bokusebenzisa i-microalloying (njengokongeza izinto ezifana ne-niobium kunye ne-titanium), isizukulwana esitsha semibhobho yentsimbi ye-Q345 sinciphisa ngakumbi ukusetyenziswa kwe-alloy ngelixa sigcina amandla, sifezekisa "ngaphezulu ngokuncinci." Ngakolunye uhlangothi, ukuphuculwa kwemveliso ehlakaniphile-ukusuka kwixesha langempela lokujonga ukubunjwa kwensimbi etyhidiweyo ukuxela kwangaphambili ukusebenza kwemveliso egqityiweyo-ukuphucula ukuzinza kwemveliso kunye namazinga emveliso ngokulawula idijithali ekupheleni kokuphela.

 
Kwiimeko zesicelo, Imibhobho yensimbi ye-Q345 iyanda kwicandelo elitsha lamandla-inkxaso yezakhiwo zeenqaba zomoya, iinqununu ezithwala imithwalo ye-photovoltaic racks, kunye nemibhobho yokuthutha i-hydrogen yonke ibeka iimfuno ezintsha kumandla wezinto eziphathekayo kunye nokuchasana kwemozulu. Ngokuphucula ukusebenza, imibhobho yensimbi ye-Q345 ngokuthe ngcembe ibe yinto ekhethiweyo kule mimandla. Ukusuka kwiindawo zedolophu ukuya kwii-corridors zamandla, ukusuka kumatshini onzima ukuya kwiziseko zoluntu, iipayipi zensimbi ze-Q345 zibonisa ixabiso leshishini lentsimbi ephantsi-i-alloy high-strength nge-benefits zabo eziphambili zamandla aphezulu, ukuqina okuphezulu, kunye nokulula ukusetyenzwa. Azimi nje njengobungqina benkqubela phambili yezobuchwepheshe kwimathiriyeli yentsimbi kodwa kwakhona “njengomqolo wentsimbi” oyimfuneko kulwakhiwo lobunjineli bale mihla. Kwinqanaba loshishino lwexesha elizayo, iipayipi zensimbi ze-Q345 ziya kuqhubeka nokuphendula kwiimfuno zamaxesha ngokusebenzisa izinto ezintsha kunye nokuphucula, ukufaka "amandla ensimbi" kwiiprojekthi eziphezulu kakhulu.
