Ialuminiyam inomjikelo wobomi apho ezinye iintsimbi ezimbalwa zinokuhambelana.Iyakwazi ukumelana nomhlwa kwaye inokuphinda isetyenziswe kwakhona, ifuna nje iqhezu lamandla asetyenzisiweyo ukuvelisa intsimbi yokuqala.
Oku kwenza i-aluminiyam ibe yimathiriyeli egqwesileyo - ilungiswe ngokutsha kwaye iphinde isetyenziswe ukuhlangabezana neemfuno kunye nemingeni yamaxesha ahlukeneyo kunye neemveliso.
Ikhonkco lexabiso leAluminiyam
1. Imigodi yeBauxite
Imveliso ye-aluminiyam iqala nge-bauxite yezinto ekrwada, equlethe i-aluminium eyi-15-25% kwaye ifumaneka kakhulu kwibhanti ejikeleze i-ikhweyitha.Kukho malunga nama-29 eebhiliyoni zeetoni zoovimba abaziwayo be-bauxite kwaye ngesantya sangoku sokutsalwa, aba vimba baya kuhlala iminyaka engaphezu kwe-100.Kukho, nangona kunjalo, izibonelelo ezininzi ezingekafunyaniswa ezinokwandisa oko ukuya kuma-250-340 iminyaka.
2. Ukucokisa ialumina
Ukusebenzisa inkqubo yeBayer, i-alumina (i-aluminium oxide) itsalwa kwi-bauxite kwindawo yokucoca.I-alumina isetyenziselwa ukuvelisa isinyithi esisisiseko kwi-2: 1 (iitoni ezi-2 ze-alumina = i-1 tonne ye-aluminium).
3. Ukuveliswa kwe-aluminiyam yokuqala
I-athomu ye-aluminiyam kwi-alumina idibene ne-oksijini kwaye idinga ukuphulwa nge-electrolysis ukuvelisa isinyithi se-aluminium.Oku kwenziwa kwimizila emikhulu yemveliso kwaye yinkqubo edinga amandla amaninzi efuna umbane omninzi.Ukusebenzisa amandla avuselelekayo kunye nokuphucula ngokuqhubekayo iindlela zethu zokuvelisa yindlela ebalulekileyo yokuhlangabezana nenjongo yethu yokungathathi hlangothi kwekhabhoni kumbono wobomi ngo-2020.
4. Ukwenziwa kweAluminiyam
I-Hydro ibonelela kwimarike ngaphezulu kwe-3 yezigidi zeetoni zeemveliso ze-aluminiyam ye-casthouse ngonyaka, isenza ukuba sibe ngababoneleli abaphambili be-extrusion ingot, i-ingot yeshiti, i-Foundry alloys kunye ne-aluminiyam ecocekileyo enobukho behlabathi.Olona setyenziso luqhelekileyo lwe-aluminiyam yokuqala kukukhupha, ukuqengqeleka kunye nokuphosa:
4.1 Ukukhutshwa kweAluminiyam
I-Extrusion ivumela ukubunjwa kwe-aluminiyam phantse kuyo nayiphi na indlela onokucinga ngayo usebenzisa iiprofayili esele zenziwe okanye ezilungiselelwe.
4.2 Ukuqengqeleka kweAluminiyam
I-aluminium foil oyisebenzisayo ekhitshini lakho ngumzekelo omhle wemveliso ye-aluminiyam eqengqelekayo.Ngenxa yokonakala kwayo okugqithisileyo, i-aluminiyam inokuqengqeleka ukusuka kwi-60 cm ukuya kwi-2 mm kwaye iqhubekeke icutshungulwa ibe yifoyile ecekethekileyo njenge-0.006 mm kwaye ingatshoni ngokupheleleyo ekukhanyeni, kwivumba nencasa.
4.3 Ukusatywa kweAluminiyam
Ukudala i-alloy ngenye isinyithi kutshintsha iipropathi ze-aluminiyam, yongeza amandla, ukuqaqamba kunye / okanye ukudumba.Iimveliso zethu ze-casthouse, ezifana ne-extrusion ingots, ii-ingots zamaphepha, ii-alloys ze-foundry, i-wire rods kunye ne-high purity aluminium, zisetyenziselwa iimoto, ukuthutha, izakhiwo, ukuhanjiswa kobushushu, i-electronics kunye ne-aviation.
5. Ukurisayikilisha
Ukurisayikilisha ialuminiyam kusebenzisa nje i-5% yamandla afunekayo ekuveliseni intsimbi yokuqala.Kwakhona, i-aluminiyam ayiwohloki ekusetyenzisweni kwakhona kwaye malunga ne-75% yayo yonke i-aluminiyam eyakha yaveliswa isasetyenziswa.Injongo yethu kukukhula ngokukhawuleza kunemarike ekusetyenzisweni ngokutsha kunye nokuthatha indawo ekhokelayo kwindawo yokurisayikilisha yekhonkco lexabiso le-aluminiyam, ukubuyisela i-1 yezigidi zeetoni ze-aluminiyam engcolileyo kunye ne-post-consumer scrap ngonyaka.
