Ukusetyenziswa kweePleti zeNsimbi ze-AH36, DH36, kunye ne-EH36 kwiProjekthi zokwakha iinqanawa kunye neeProjekthi zaseLwandle

Kwimizi-mveliso yaselwandle neyaselwandle kwihlabathi liphela, iipleyiti zentsimbi zidlala indima ebalulekileyo ekuqinisekiseni ukuthembeka kwesakhiwo, ukhuseleko, kunye nobude bexesha leenqanawa kunye namaqonga asebenza kwezinye zezona ndawo zinzima eMhlabeni. Phakathi kwezinto ezisetyenziswa kakhulu kukhoIipleyiti zentsimbi ze-AH36, DH36, kunye ne-EH36, ezikwicandelo lentsimbi yesakhiwo esomeleleyo phantsi kwemigangatho ye-ASTM A131. Ezi nqanaba zenzelwe ukumelana nemithwalo enzima, iimpembelelo, kunye neemeko zaselwandle ezirhabaxa, nto leyo eyenza ukuba zibe yimfuneko kwiiprojekthi zanamhlanje zokwakha iinqanawa kunye nobunjineli baselwandle.

At i-sakyalloy, sinikezela ngomgangatho ophezuluIipleyiti zentsimbi ze-AH36, DH36, kunye ne-EH36ezihlangabezana nemigangatho yamazwe ngamazwe kwaye zibonelela ngokusebenza okuzinzileyo kwiindlela ezahlukeneyo zokusebenza ezifuna amandla.

1. Isishwankathelo seeNqanaba zeNsimbi ze-AH36, DH36, kunye ne-EH36

I-AH36, i-DH36, kunye ne-EH36 ziintsimbi zaselwandle ezinamandla aphezulu ezisetyenziswa kakhulu ekwakheni iinqanawa kunye nezakhiwo zaselwandle. Umahluko ophambili phakathi kwezi ntlobo ukwimeko yazo.iimfuno zokuqina kwempembelelokumaqondo obushushu ahlukeneyo:

  • AH36: Ivavanywe kwi-0°C (ukuqina kobushushu begumbi)

  • DH36: Ivavanywe kwi -20°C (ukuqina kobushushu obuphantsi)

  • I-EH36: Ivavanywe kwi -40°C (ukuqina okugqithisileyo kubushushu obuphantsi)

Ezi klasi zabelana ngokwakhiwa kweekhemikhali ezifanayo kunye neempawu zoomatshini, zibonelela ngomxube ofanelekileyo weamandla okukhupha (ubuncinci be-355 MPa)kwayeamandla okutsalwa (490–620 MPa), eqinisekisa ukuba ithwala umthwalo ophezulu kwaye iyamelana nokuguquguquka.

2. Iimpawu zeKhemikhali nezeMishini

Ukwakheka kweekhemikhali zeepleyiti zentsimbi ze-AH36, DH36, kunye ne-EH36 kudla ngokuquka oku kulandelayo:

  • Ikhabhoni (C):≤ 0.18%

  • IManganese (Mn):0.90–1.60%

  • I-Silicon (Si):0.10–0.50%

  • I-Phosphorus (P):≤ 0.035%

  • I-Sulfur (S):≤ 0.035%

Ezi ntsimbi zinokuba nazoizinto ezidibanisa izinto ezincinciezifana ne-niobium, i-vanadium, kunye ne-titanium ukuphucula ukucocwa kweenkozo nokuphucula ukuqina kwazo.

Iipropati zoomatshini:

  • Amandla okuvelisa: ≥ 355 MPa

  • Amandla okuThamba: 490–620 MPa

  • Ukwandiswa: ≥ 21%

  • Uvavanyo lweCharpy V-notch Impact: 0°C (AH36), -20°C (DH36), -40°C (EH36)

Olu didi lubalaseleyo lokuqina nokuqina luvumela la manqanaba ukuba ahlale ekwazi ukudityaniswa kakuhle kwaye elungelelene ngexesha lokwenziwa.

3. Izicelo kwiShishini loKwakha iinqanawa

a. Ukwakhiwa kweeHull

Isiqu senqanawa sisisiseko sayo nayiphi na inqanawa, ifuna izinto ezinokunyamezela uxinzelelo oluxinzelelweyo nolugobileyo. Iipleyiti zentsimbi ze-AH36, DH36, kunye ne-EH36 zisetyenziswa kakhuluipleyiti yehake, izakhiwo zedekhikunyeiindawo ze-keel.

Ezi zinto zilungele oku kulandelayo:

Kwizicelo zamanzi angaphantsi kolwandle, amanqanaba e-DH36 kunye ne-EH36 asetyenziswaizitya zoxinzelelo, izixhasi zemibhobho, kunye neefreyimu zesakhiwo ezingaphantsi kolwandle, ukuqinisekisa ukuqina kwexesha elide ekudinweni nasekugqwaleni.

5. Ukwenziwa kunye nokusebenza kweWelding

Enye yezona nzuzo ziphambili zeepleyiti zentsimbi ze-AH36, DH36, kunye ne-EH36 kukubaukuwelda okugqwesileyo kunye nokusebenza kakuhleZingadityaniswa kusetyenziswa iindlela eziqhelekileyo ezifana nezi:

  • Ukuwelda kwe-Arc yesinyithi esikhuselweyo (i-SMAW)

  • Ukuwelda kwe-Arc yeGesi yeMetal (GMAW)

  • Ukuwelda kwe-Flux-Cored Arc (FCAW)

Ixabiso labo elilinganayo lekhabhoni ephantsi (i-CEV) liqinisekisaumngcipheko omncinci wokuqhekekangexesha lokuwelda kunye nokumelana okuphezulu nokuqhekeka kwendawo echaphazeleka bubushushu. Unyango lobushushu emva kokuwelda alufuneki rhoqo, nto leyo eyenza ukwenziwa kube lula kwaye kube neendleko eziphantsi.

At i-sakyalloy, zonke iipleyiti ziphantsiuvavanyo lwe-ultrasound, ukuhlolwa kobukhulu, kunye nokuqinisekiswa kwepropathi yoomatshiniukuqinisekisa ukuthotyelwa kwemigangatho ye-ASTM, ABS, LR, DNV, kunye ne-BV.

6. Ukumelana nokugqwala kunye nonyango lomphezulu

Ukusebenza kwiindawo zaselwandle kubeka izakhiwo zentsimbi esichengeni sokuhlaselwa rhoqo ngamanzi anetyuwa, ukufuma, kunye nongcoliseko lomoya. Iintsimbi ze-AH36, DH36, kunye ne-EH36 zibonisa ukumelana okuhle nokugqwala ngenxa yokuxubana okulawulwayo kwaye zinokukhuselwa ngakumbi ngale ndlela ilandelayo:
