Iimfuno zenkqubo yokunyibilikisa amalaphu e-aluminiyam a iziko elinyibilikayo.

1. Iimfuno zenkqubo

1.1 Ngaphambi kokuba unyibilikise i-aluminium scraps kwisithando somlilo, yongeza isiqingatha somlilo wamanzi e-aluminium (malunga ne-3t) kwisithando somlilo esilinganisiweyo kunye nesithando somlilo, ukushisa ukuya kwi-720-760 ℃ kwaye ucime umlilo, yongeza inani elifanelekileyo le-aluminium scraps. , yongeza i-aluminium scraps kwaye usebenzise i-slag rake ukuze ubasuse. Iimvuthuluka ze-aluminiyam kumphezulu ongaphakathi weziko zicinezelwa kancinane ukuya kwi-aluminiyam etyhidiweyo (ukuthintela amanzi akwi-aluminiyam kwiimvuthuluka ekuqhumeni). Emva kokucinezela phantsi, sebenzisa i-rake ye-slag ukuphazamisa uluhlu olukhulu. Emva kokuba ukuvuselela ngokupheleleyo kugqityiwe (akukho mlilo ovulekileyo okanye i-aluminium scrap evunyelwe kwindawo yangaphakathi yesithando somlilo), yongeza i-aluminiyam efanelekileyo njengoko kufuneka. Iimfuno zokusebenza ziyafana nezingasentla. Xa iqondo lokushisa kwisithando somlilo lingaphantsi kwama-680 ° C, yeka ukongeza i-aluminium scraps, vala umnyango wesithando sokunyusa izinga lokushisa emva kokutshisa, uze ungeze i-aluminium scraps emva kokufudumala kwi-720-760 ° C kwaye ucime umlilo. Umsebenzi uyafana nongasentla.

1.2 Emva kokuba i-aluminium etyhidiweyo izaliswe kwisithando somlilo, ukushisa kuphakanyiswe kwi-720-760 ℃, i-agent yokucoca i-slag yongezwa ngokwe-0.2-0.3% yobunzima be-aluminium etyhidiweyo, kwaye emva koko i-slag isusiwe. Kuyimfuneko ukudlulisa i-aluminiyam etyhidiweyo kwisithando somlilo esinyibilikayo seworkshop entsha.

1.3 Ukulungelelanisa iziko emva kokuba i-aluminiyam ibekwe, kwaye isiqingatha se-aluminiyam etyhidiweyo kufuneka ishiywe kwisithando somlinganiso, kwaye emva koko wenze 2.1

1.4 Lungisa ubushushu kwisithando somlilo ukuya kwi-720-750℃, faka i-aluminium etyhidiweyo kwi-tundish, kwaye ufefe ngokulinganayo i-1 kg ye-agent yokucoca i-slag xa ubeka i-aluminium, sebenzisa i-0.5 kg ye-ejenti yokucoca i-degassing yokucoca emva kokucocwa, kwaye ususe i-agent etyhidiweyo. ialuminiyam emva kokucokiswa Igqithiselwe kwiziko lokunyibilika kwiworkshop entsha.

1.5 Coca iziko lokulinganisa kunye neziko lohlengahlengiso rhoqo ngeentsuku ezintathu kwishifti yosuku.

2. Iimfuno zokunyibilikisa i-aluminiyam i-scraps kwisithando somlilo

Zonke iitshiphusi ze-aluminiyam ezibuyisiweyo kufuneka zigcinwe zomile, zicocekile kwaye zingenankunkuma.

Umsebenzisi kufuneka anxibe i-inshurensi epheleleyo yomsebenzi ngexesha lokusebenza, kubandakanya imaski, izihlangu ze-inshurensi yabasebenzi, iiglavu, njl.

Izixhobo ezisetyenzisiweyo ze-aluminiyam, ulwelo oluveliswayo lwe-aluminiyam, kunye nothuthu lwe-aluminiyam kufuneka zilinganiswe kwaye zirekhodwe.
