Ukusetyenziswa kweumhlaba onqabileyoekuphoseni i-aluminium ingxubevange yenziwa ngaphambili phesheya. Nangona i-China yaqala uphando kunye nokusetyenziswa kwalo mba kuphela kwi-1960s, iphuhliswe ngokukhawuleza. Mninzi umsebenzi owenziweyo ukusuka kuphando lwendlela ukuya kwisicelo esisebenzayo, kwaye ezinye impumelelo zenziwe.Ngokongezwa kwezinto ezinqabileyo zomhlaba, iipropati zomatshini, iipropati zokuphosa kunye neempawu zombane ze-aluminium alloys ziye zaphuculwa kakhulu. izixhobo ezintsha, izinto ezityebileyo zamehlo, zombane kunye nemagnethi zezinto ezinqabileyo zomhlaba nazo zidlala indima ebalulekileyo ekwenzeni imathiriyeli yamagnetic enqabileyo yomhlaba, izinto ezinqabileyo ezikhupha ukukhanya komhlaba, izinto ezinqabileyo zokugcina i-hydrogen, njl.
◆ ◆ Indlela yokusebenza yomhlaba onqabileyo kwi-aluminium kunye ne-aluminium alloy ◆ ◆
Umhlaba onqabileyo unomsebenzi ophezulu weekhemikhali, amandla aphantsi kunye nelungiselelo elikhethekileyo le-electron layer, kwaye unokusebenzisana phantse nazo zonke izinto.lanthanum), Ce (i-cerium), Y (iyttrium) kunye noSc (scandium). Zihlala zongezwa kwi-aluminium liquid kunye ne-modifiers, i-nucleating agents kunye ne-degassing agents, ezinokuhlambulula ukunyibilika, ukuphucula isakhiwo, ukucokisa ingqolowa, njl.
01Ukucocwa komhlaba onqabileyo
Njengomlinganiselo omkhulu wegesi kunye ne-oxide inclusions (ikakhulukazi i-hydrogen, i-oksijini kunye ne-nitrogen) iya kufakwa ngexesha lokunyibilika kunye nokuchithwa kwe-aluminium alloy, i-pinholes, ii-cracks, inclusions kunye nezinye iziphene ziya kwenzeka kwi-casting (jonga umfanekiso 1a), ukunciphisa amandla e-aluminium alloy.Isiphumo sokuhlanjululwa komhlaba onqabileyo sibonakaliswa ngokukodwa ekunciphiseni okucacileyo komxholo we-hydrogen kwi-aluminium etyhidiweyo, ukunciphisa izinga le-pinhole kunye ne-porosity (jonga i-Figure 1b), kunye nokunciphisa ukubandakanywa kunye nezinto ezinobungozi.Isizathu esona sizathu kukuba umhlaba onqabileyo unobudlelwane obukhulu kunye ne-hydrogen, enokuthi ifunxe kwaye ichithe i-hydrogen ngobuninzi kwaye yenza iikhompawundi ezizinzile ngaphandle ukwenza amaqamza, ngaloo ndlela kunciphisa ngokubonakalayo umxholo we-hydrogen kunye nokuvuvuka kwe-aluminiyam; ngendlela ye-slag kwinkqubo yokunyibilikisa, ukuze kufezekiswe injongo yokucoca ulwelo lwe-aluminium.
Ukuziqhelanisa kubonise ukuba umhlaba onqabileyo unempembelelo yokunciphisa umxholo we-hydrogen, i-oksijini kunye nesulfure kwi-aluminium kunye ne-aluminium alloys. Ukongeza i-0.1% ~ 0.3% RE kulwelo lwe-aluminiyam luncedo ekususeni ngcono ukungcola okuyingozi, ukucokisa ukungcola okanye ukutshintsha imo yaboji, ukuze kusulungekiswe kwaye kusasazwe ngokulinganayo iinkozo; Ukongeza, iRE kunye nokungcola okuyingozi kunye nendawo yokunyibilika esezantsi zenza imidibaniso yokubini efana I-RES, ii-REAs, kunye ne-REPb, eziphawulwa ngendawo yokunyibilika ephezulu, ukuxinana okuphantsi, kunye neempawu zekhemikhali ezizinzileyo, kwaye zinokubakho. idandwe phezulu ukuze yenze i-slag kwaye isuswe, ngaloo ndlela icoca ulwelo lwe-aluminium;
