Emhlabeni wokukhiqiza i-aluminium, Inqubo yokugoqa idlala indima ebalulekile ekunqumeni izakhiwo zokugcina kanye nekhwalithi yamakhoyili we-aluminium. Le blog post ihlela izindlela ezihlukile zokugoqa amakhoyili we-aluminium, Ukugxila ekuqhubekeni kwe-cast-rolling okuqhubekayo nokuqhutshwa okuqhubekayo nokugoqa, kanye nokugoqa okushisayo nokugoqa okubandayo.

Izinqubo zokukhiqiza ezijwayelekile ze-Aluminium Plate zingafingqiswa kanjena:

Ukugibela okuqhubekayo: I-Aluminium Slab 7-8 amamilimitha ahlanganisiwe, Lapho-ke kubanda kubukhali kubukhulu obufunayo;

Ukuphonsa okuqhubekayo nokugoqa: I-Aluminium Slab 15-20 amamilimitha, ukufudumeza nokuvutha okunamathathu okushisayo kugoqiwe 1-2 amamilimitha, Kuqediwe noma kuqhubeke okubandayo kugoqwe ezintweni ezincanyana;

Kuvutha ukuqeda ukugoqa 3-4 amamilimitha, kupholile futhi kwahlanganiswa, Lapho-ke kubanda kubukhali kubukhulu obufunayo.

Ngokuya ngekhwalithi ephezulu: Ukugibela okuqhubekayo okuphezulu kuphakeme kunokugoqa okushisayo, okuphakeme kunokuphonsa okuqhubekayo nokugoqa.

Ngokuya ngezezakhiwo zemishini: Ukugoqa okushisayo kuphakeme kunokuphonsa okuqhubekayo nokugoqa, okuphakeme kunokuphonsa okuqhubekayo okuqhubekayo.

Imikhiqizo eye yaqhubeka nokugibela okubandayo inendawo enhle, Ubukhulu obuqondile, kanye nokwanda okukhulu kwamandla ashubile kanye nokugcwala, Ukubenza babaluleke kakhulu kwizicelo ezidinga ukwenziwa kwemali okukhulu okulandelayo.

Ukugibela okuqhubekayo

Ukugibela okuqhubekayo, eyaziwa nangokuthi i-Direct Chill Rolling noma i-Liquid Rolling, kuyinqubo lapho insimbi ewuketshezi ithululelwa ngqo kwi-roll gag ukwenza imikhiqizo eqediwe noma eqediwe. Ama-rolls asebenza njengezinhlaka zensimbi ewuketshezi futhi ngasikhathi sinye zisebenzisa ingcindezi yokulimaza insimbi. Njengoba i-aluminium ewuketshezi ingena endaweni yokuphonsa nokugoqa ngokusebenzisa i-nozzle yokudla, Ihlangabezana nokuphonsa okujikelezayo kanye nokugoqa ama-roll.

Ukushisa okuvela ku-aluminium uketshezi kudonswa ngokushesha ngamanzi apholile kuma-rolls, okubangela ukwehla okusheshayo kwezinga lokushisa nokuqina endaweni yomngcele. Ama-rolls abese asebenzisa inani elithile lokwehliswa kwe-rolling ukuze wakhe ikhoyili esongwe. Ukufakwa kanye nokukhishwa kwensimbi endaweni yokusakaza nokugoqa kuhlala kulinganiselwe, Ukuqinisekisa ukusakazeka okuqhubekayo okuqhubekayo kanye nenqubo yokugoqa.

Ngokuvamile, Ububanzi be-slab bunqunywa ububanzi bomkhiqizo obuqediwe obuchazwe ku-oda. Ubukhulu obujwayelekile obukhona 7-8 amamilimitha, ngobubanzi obuphezulu bufika 2000 amamilimitha.

Njengoba inqubo yenzeka emazingeni okushisa aqinile wombuso, okukhiqizwayo okukhiqizwayo kunesakhiwo esikhulu sokusanhlamvu. Nokho, Ngenxa yokushisa okuphansi kokusebenza, Akunasikali se-oxide ebusweni, okuholela ekuqedeni okuphezulu. Kepha i-couctility iphansi.

Ukuphonsa okuqhubekayo nokugoqa

Ukuphonsa okuqhubekayo nokugoqa kufaka phakathi ukuqina kwensimbi ewuketshezi ku-slab ekubumbeni kwe-caster eqhubekayo, Yikuphi bese kugoqwa ngokuqondile esigangeni esigoqisayo ngenkathi kusashisa, noma ngemuva kokuvuselelwa okuncane, Ukuqedela inqubo yokukhubazeka. Ngokungafani ne-cast-rolling eqhubekayo, Akunasinyathelo sokupholisa nokukholisa ekukhokhisweni okuqhubekayo nokugoqa.

I-slab ifudumele ngokuqondile bese igoqa. Ukuba khona kwesinyathelo sokushisa kuthinta impahla yokwenziwa, Ukwenza kube lula ukwenziwa kabusha kwepulasitiki kuqhathaniswa nokuqhuma okuqhubekayo. Umkhiqizo osuqediwe une-decticility engcono futhi uzinzile ngokwengeziwe kuzinhlelo zokusebenza ezidinga ukucubungula okulandelayo kwezoguquko.

Okwamanje, ukulangazelela kuphela futhi u-ding sheng (I-mongolia yangaphakathi) Amafektri akhiqiza ukusakaza okuqhubekayo kanye nezinto zokwakha usebenzisa i-hazelett eqhubekayo yokusakaza kanye nobuchwepheshe bokugibela. Lobu buchwepheshe busetshenziswe kwezentengiselwano ngawo-1960, Kepha ukusetshenziswa kwayo kanye nocwaningo eChina kufushane.

Phakathi kwa- 2009, ULongang Iguguang Nual-Premidan Drank Plate Co, Ltd. (I-Luoyang ilanga) wethule i-hazelett yokuqala yaseChina yokuphonsa okuqhubekayo kanye nomugqa wokugoqa, okwabekwa ekukhiqizweni ngoMashi 2011. Phakathi kwa- 2013, I-Inner Mongolia Liansheng New Energy Materials yethule i-Hazelett yesibili ye-Hazelett yesibili yaseChina kanye nomugqa wokugoqa, okwabekwa ekukhiqizweni ngo-Ephreli 2018.

Yomibili imigqa yokukhiqiza inobubanzi bokuklama 2100 amamilimitha kanye nomklamo ohlanganisiwe wokuklama we 400,000 amathani. Phakathi kwa- 2018, Imigqa emibili ikhiqize ingqikithi ye 250,000 amathani, naku 2019, 350,000 amathani. Ngokwesakhiwo somkhiqizo, Ukulangazelela kukhiqiza ikakhulukazi i-foil ehlukahlukene ye-zero, ibhande lekhebula, ibhande lepuleti lokuhlobisa, Izinto zokudweba ezijulile, kanye nezinto ezibonakalayo ze-radiator zezimoto, ngokuphuma konyaka mayelana 180,000 ku 200,000 amathani. Imikhiqizo kaLiansheng ikakhulukazi ifaka phakathi i-foil ephindwe kabili ye-zero, I-foil eyodwa-zero, I-foil yomoya, kanye nezinto ezibonakalayo ze-radiator zezimoto.

Ukwakheka kwenqubo eqhubekayo yokusakaza kanye nenqubo yokugoqa kufaka iqembu lokuncibilika lomthamo, idivaysi ye-inthanethi ye-online kanye ne-dross resex, umshini we-slab (Inqubo eyisisekelo kanye nophawu oluhlukanisa nalobunye ubuchwepheshe benqubo), nokugoqa okushisayo okushisayo okuthathu. Ubukhulu be-slab bunxa 15-20 amamilimitha, Futhi ubukhulu bomkhiqizo obuqediwe bukhona 1-2 amamilimitha.

Ukulawulwa kokushisa kubalulekile. Ukuthatha 8011 alloy njengesibonelo, Izinga lokushisa le-casting lingu-690-700 ° C, Ukushisa kwe-slab ngu-450-550 ° C, Amazinga okushisa okuqala angu-400-500 ° C, futhi izinga lokushisa lokugcina lingu-120-250 ° C. Lokushisa kabusha kabusha kwe 8011 I-Alloy ngokuvamile ingu-300-350 ° C. Ngaphansi kwalezi zinqubo zenqubo, ukukhiqizwa kwe 8011 I-Aluminium Strip inomphumela ofana naleyo yamakhoyili asongwe.

Ngokuya ngekhwalithi ephezulu, qhathanisa nokuphonsa okuqhubekayo, indawo ye-slab inokuphamba okuningi, futhi ukuhlukaniswa kokwakheka kwamakhemikhali ebusweni kubangelwa ukupholisa okungalingani (ukugcwala kokungcola esibonakalayo kuphakeme kakhulu kunalokho emzimbeni).

Izinkinga eziphambili zibonakaliswa njengezinhlamvu ezingezinhle zekhoyili ye-aluminium, ukukhanya okusobala nemivimbo emnyama, futhi ezimweni ezinzima, ukuba khona kwemigqa ye-black silk. Eminyakeni yakamuva, Ngokusebenzisa ubuchwepheshe, Ngaphandle kwemikhiqizo enezidingo ezingaphezulu ngokweqile ezifana nesisekelo seplanethi ye-CTP, isibuko aluminium, kanye neplate ye-oxidation, Iningi lezimfuno zomkhiqizo zingahlangatshezwa.

Izakhiwo zemishini ziphakathi kokuphoqelelwa okuqhubekayo okuqhubekayo nokugoqa okushisayo. Njengoba izinga lokushisa le-slab lihlala lingaphezulu kokushisa okuphindaphindiwe lapho ungena ngokuhamba okushisayo okuqhubekayo, kungokwesigaba esishisayo esishisayo, futhi ukusebenza kusondele ekugibeleni okushisayo.

Ukushisa okushisayo vs. I-Cold Rolling

I-Hot Rolling

I-Hot Rolling yinqubo yokugoqa eyenziwe ngenhla kokushisa kabusha kokuvuselela kabusha. Mane nje ubeke, I-aluminium billet ifudumele bese igobhoza ngokudlula okuningana, kulandelwa ukuncipha okukhulu nokuqondisa ukuqondisa ipuleti ye-aluminium, okubizwa ngokuthi ukugoqa okushisayo.

Ngesikhathi sokugoqa okushisayo, Insimbi ineplastikini ephezulu kanye nokumelana okuphansi kwezenkolo, ukunciphisa kakhulu ukusetshenziswa kwamandla kwe-metal deformation. Ukujikeleza okushisayo kungathuthukisa ukusebenza kwezinsimbi kanye nama-alloys. Iphula okusanhlamvu kwama-coarse esimweni sokuphosa, uphulukisa imifantu ebalulekile, kunciphisa noma kuqede izinkinga zokuphonsa, futhi iguqula ukwakheka kwesakhiwo esichithiwe, Ngaleyo ndlela kuthuthukisa ukusebenza kwe-alloy.

Ukugeleza kwenqubo kungokulandelayo: I-Aluminimum Ingot – Ingot Flat – ukugaya – Ukuvuselelwa okufanayo (ukufudumeza) – Ukugoqa okushisayo okushisayo – Kushisa okushisayo – ukupholisa nokukholisa.

Ngesikhathi senqubo yokufudumeza nokuhamba kuya esikhungweni esigoqisayo, I-Ingot efulethini ihlangana nomoya-mpilo emoyeni, kwakha isikali se-oxide ebusweni. Uma ungqimba lwe-oxide luhlala kulokho okwenziwa ngesikhathi sokugoqa, Ingangeniswa ngaphakathi ngaphakathi kwezinto ze-aluminium, okuthinta ikhwalithi ephezulu yomkhiqizo wokugcina. Ngakho-ke, Ukugaya kuyadingeka ngaphambi kokugibela okunzima.
Ukushisa okufudumele kwe-Ingot Flat ngaphambi kokuqubuka okushisayo kungaphezulu kwama-400 ° C.

Kusuka endaweni yokubuka ebonakalayo, Inqubo eshisayo eshisayo ayihileli ukugoqa okubandayo. Nokho, ekukhiqizweni kwangempela, amafektri angezelela isinyathelo esibandayo sokugibela ukunciphisa ukusetshenziswa kwamandla, Qinisekisa ukunemba okubucayi kanye nekhwalithi ephezulu yomkhiqizo oqediwe. Ngokuvamile, Ubukhulu besibabule ngemuva kokuqeda ukugoqa kulawulwa ngenhla 3.0/4.7 amamilimitha.

Ubungako be-Ingot yePlate buhlobene nokucaciswa kwe-oda, Kepha ukuhlangana okuthile akwaziwa.

I-Cold Rolling

Ukugibela okubandayo kubhekise ekuguqukeni kwe-rolling yensimbi ngaphansi kwendlela yokushisa kabusha, ngokuvamile okusho ukuthi amakhoyili we-aluminium agoqwa ngqo ekushiseni kwegumbi ngaphandle kokushisa.

Ukugeleza kwenqubo kungokulandelayo: cast slab – ukupholisa nokukholisa – Kushisa okushisayo – ukupholisa nokukholisa – ukugoqa okubandayo.

Yize ikhoyili ye-aluminium ingahle ifudumele ekuthinteni ngemuva kokugoqa okubandayo, Kusabizwa ngokuthi yi-Collecting Colling.

Qhathanisa nokugoqa okushisayo, Ukugibela okubandayo kunezinzuzo ezilandelayo:

1. Izinga lokushisa eliphansi, okuholele ekuphakameni okuqondile kanye nobukhulu be-aluminium obukhonziwe;
2. Amandla okukhiqiza izinto ezincanyana kakhulu ze-strip ezingenakukhiqizwa ngokugoqa okushisayo;
3. Ikhwalithi ephezulu yemikhiqizo ebandayo, Imahhala kusuka ekulimaleni okunjengokufakwa kwe-iron ye-iron ne-oxide ye-iron ejwayelekile etholakala kakhulu emikhiqizweni evuthayo, okuzuzisa ukucubungula okulandelayo;
4. Ama-Cold Plate Colling Coils anezakhiwo ezinhle kakhulu zemishini nezicubungula, njengamandla aphezulu, umkhawulo wesivuno ophansi, kanye nokusebenza okuhle kokudweba okujulile;
5. Ukusebenza kahle okuphezulu ngenxa yekhono lokuthola ukugoqa okusheshayo nokugoqa okugcwele okuqhubekayo.
