Ukusetshenziswa kwe-High-End Aluminium Alloys ku-Marine Engineering

Ama-alloys e-aluminium ekusetshenzisweni kwamapulatifomu ezindiza ezinophephela emhlane zasolwandle

Insimbi ivamise ukusetshenziswa njengento eyinhloko yesakhiwo kumapulatifomu okumba uwoyela ngasogwini ngenxa yamandla ayo aphezulu. Kodwa-ke, ibhekene nezinkinga ezifana nokugqwala kanye nempilo efushane uma ibhekene nemvelo yasolwandle. Kungqalasizinda yokuthuthukiswa kwezinsiza zikawoyela negesi yasogwini, izindawo zokuhlala ezikhumulweni ezinophephela emhlane zidlala indima ebalulekile ekusizeni ukusuka kanye nokufika kwendiza enophephela emhlane, okusebenza njengesixhumanisi esibalulekile ezwenikazi. Amamojula edekhi yendiza enophephela emhlane enziwe nge-aluminium asetshenziswa kabanzi ngenxa yokuthi angasindi, anamandla amakhulu nokuqina, futhi ahlangabezana nezidingo zokusebenza ezidingekayo.

Amaplathifomu anophephela emhlane we-aluminium alloy ahlanganisa uhlaka kanye nedekhi eyenziwe ngamaphrofayili ealloy ehlanganisiwe anomumo ophambanayo ofana nohlamvu elithi “H,” elinezimbobo zamapuleti anezimbambo ezitholakala phakathi kwamapuleti edekhi engenhla nangaphansi. Ngokusebenzisa izimiso zobukhenika namandla okugoba amaphrofayili e-aluminium alloy, inkundla ihlangabezana nezidingo zokusebenza ngenkathi yehlisa isisindo sayo. Ukwengeza, endaweni yasolwandle, amapulatifomu e-aluminium alloy helicopter kulula ukuwagcina, anokumelana nokugqwala okuhle, futhi, ngenxa yomklamo wabo wephrofayili ohlangene, awudingi ukushisela. Lokhu kungabikho kokushisela kususa indawo ethinteke ukushisa ehambisana nokushisela, kunwebe isikhathi sempilo yesikhulumi futhi kuvimbele ukwehluleka.

Ukusetshenziswa kwama-alloys e-LNG (Liquefied Natural Gas) emikhunjini yezimpahla

Njengoba imithombo kawoyela negesi yasogwini iqhubeka nokuthuthukiswa, izindawo eziningi ezinkulu zegesi yemvelo ezitholakalayo nezifunwayo ziqhelelene futhi zivame ukuhlukaniswa izilwandle ezinkulu. Ngakho-ke, indlela eyinhloko yokuthutha igesi yemvelo ewuketshezi yimikhumbi ehamba olwandle. Ukwakhiwa kwamathangi okugcina umkhumbi we-LNG kudinga insimbi esebenza kahle kakhulu ekushiseni okuphansi, kanye namandla anele kanye nokuqina. Izinto ze-aluminium alloy zibonisa amandla aphezulu emazingeni okushisa aphansi uma kuqhathaniswa nezinga lokushisa legumbi, futhi izici zazo ezingasindi zizenza zilungele ukusetshenziswa emkhathini wasolwandle, lapho zimelana nokugqwala.

Ekwenziweni kwemikhumbi ye-LNG namathangi okugcina e-LNG, i-aluminium alloy engu-5083 isetshenziswa kabanzi, ikakhulukazi eJapan, omunye wabangenisi abakhulu begesi yemvelo ewuketshezi. I-Japan yakhe uchungechunge lwamathangi e-LNG nemikhumbi yokuthutha kusukela ngeminyaka yawo-1950s kanye nawo-1960s, enezakhiwo zomzimba eziyinhloko ezenziwe ngokuphelele nge-5083 aluminium alloy. Ama-alloys amaningi e-aluminium, ngenxa yezakhiwo zawo ezingasindi futhi ezimelana nokugqwala, abe yizinto ezibalulekile ezakhiweni eziphezulu zala mathangi. Njengamanje, izinkampani ezimbalwa kuphela emhlabeni wonke ezingakhiqiza izinto ze-aluminium ezinezinga lokushisa eliphansi zamathangi okugcina umkhumbi we-LNG. Ingxubevange yaseJapan engu-5083 aluminium, enogqinsi oluyi-160mm, ibonisa ukuqina okuhle kakhulu kwezinga lokushisa eliphansi kanye nokumelana nokukhathala.

Ukusetshenziswa kwama-alloys e-aluminium kumishini yendawo yemikhumbi

Imishini yasesikhungweni semikhumbi efana nama-gangways, amabhuloho antantayo, nemigwaqo yokuhambahamba yenziwa kusukela kumaphrofayili angu-6005A noma angu-6060 we-aluminium alloy ngokusebenzisa ukushisela. Amadokhu antantayo akhiwe ngamapuleti e-aluminium alloy ashiselwe angu-5754 futhi awadingi umdwebo noma ukwelashwa ngamakhemikhali ngenxa yokwakhiwa kwawo okungangeni manzi.

Amapayipi e-aluminium alloy drill

Amapayipi okubhola i-aluminium alloy athandwa ngenxa yokuminyana kwawo okuphansi, angasindi, isilinganiso esiphezulu samandla nesisindo, itorque edingekayo ephansi, ukumelana nomthelela oqinile, ukumelana nokugqwala okuhle, kanye nokumelana nokungqubuzana okuphansi ezindongeni zemithombo. Lapho amandla omshini wokumba evuma, ukusetshenziswa kwamapayipi okubhoboza ingxube ye-aluminium kungafinyelela ukujula okungenakufinyelelwa amapayipi okubhoboza insimbi. Amapayipi okubhoboza ingxube ye-aluminium asetshenziswe ngempumelelo ekuhloleni i-petroleum kusukela ngeminyaka yawo-1960, asetshenziswa kabanzi endaweni eyayingaphansi kweSoviet Union, lapho afinyelela ekujuleni okungama-70% kuya ku-75% ukujula okuphelele. Ukuhlanganisa izinzuzo zama-alloys e-aluminium asebenza kahle kakhulu kanye nokumelana nokugqwala kwamanzi olwandle, amapayipi okubhoboza ingxube ye-aluminium anemisebenzi ebalulekile engaba khona ebunjiniyela basolwandle kumapulatifomu okumba asogwini.
