Ulwazi oluyisisekelo lwe-aluminium engagxili ama-castable
Lolu chungechunge lwezinto zokwakha luwuhlobo olusha lwezinto ezinosimende ophansi kanye nenhlanganisela ye-ultrafine powder esekelwe ku-high-purity mullite, i-andalusite ne-sillimanite.Ngenxa yokuhlanganiswa kwezinto zokusetshenziswa ezimsulwa kakhulu kanye nempushana ecwebezelayo, lolu chungechunge lwezinto zokwakha lunokuminyana kwenqwaba, amandla aphezulu, nokuzinza okuhle kokushaqeka okushisayo.Usawoti, njll.), kunganciphisa kakhulu ukumanzisa kwe-aluminium nama-alloys kanye ne-slag ezintweni eziphikisayo, futhi kuthuthukise ukumelana nokugqwala, ukumelana nokuguguleka, kanye nokunganamatheli kwezinto eziphikisayo ze-aluminium oketshezini lwe-aluminium oluqukethe izingxenye zamakhemikhali ezifana nosawoti kanye ne-flux.Umsebenzi we-slag kanye ne-slag uvimbela i-aluminium nama-alloys kanye ne-slag ekungeneni ezintweni eziphikisayo, okunweba impilo yomugqa wesithando somlilo.Ilungele izithando zomlilo ezincibilikayo, izifutho ezimile, iziwashi, amalayini okuvala i-aluminium.
