Hlobo luni lwe-induction furnace refractory ramming esetshenziselwa i-aluminium master alloy?

Ukusetshenziswa kwezinto ezinqamulelayo zesithando somlilo sokungeniswa kuma-alloys ayinhloko Muva nje, bayanda abakhiqizi bama-alloys ayinhloko we-induction furnace abancibilikisiwe, futhi izidingo zezinto ezinqamulelayo ze-induction refractory ziye zaba phezulu kakhulu. Izidingo zokungafinyeleli, ukuqina, ukumelana nokugqwala, njll. ziphakeme kakhulu kunezimfuneko zangaphambilini, futhi sithemba nokuthi izindleko zingancishiswa. Ngokuvumelana nesidingo nezidingo zemakethe, ifekthri yezinto zokushisa ezisezingeni eliphezulu isiphumelele ukuhlola nokuhlola okuqhubekayo. Ithuthukise ngempumelelo inqwaba yamakhasimende e-alloy endaweni yasendaweni, futhi izuze idumela elihle futhi yazuza ukunconywa kumakhasimende. Ama-alloys amanje emakethe ngokuvamile asekelwe ku-aluminium silicon, i-aluminium yethusi, i-aluminium iron, i-aluminium titanium boron njalonjalo. Izinga lokushisa lokuncibilikisa ngokuvamile alikho phezulu njengalelo lokuncibilikisa insimbi, kodwa lingaphezu kwezinga lokushisa elijwayelekile lokuncibilikisa i-aluminium.

Ngenxa yokuqina kwe-aluminium, ingabhola uma ubona umthungo, futhi umsebenzi we-aluminium uphakeme kakhulu, othambekele ekuphenduleni esikhundleni. Ngakho-ke, izinto eziningi ezijwayelekile zokugqoka isithando somlilo azikwazi ukukhiqizwa ezithandweni ezimbalwa. Ngakho-ke, manje sekuyinsakavukela umchilo wesidwaba ukusebenzisa graphite crucible nge induction isithando refractory ramming materials. Kodwa-ke, ukungalungi kwezinto eziphikisayo ze-ramming yesithando somlilo esivamile ukuthi uma i-graphite crucible iphukile, umugqa wesithando somlilo kufanele ususwe, ngaphandle kwalokho isithando somlilo kulula ukugqoka. Impahla yethu esanda kwakhiwa ephikisayo ye-refractory ramming yesithando somlilo ayikwazi ukusetshenziswa yodwa kuphela kodwa futhi ingasetshenziswa nezinsimbi ze-graphite. Endabeni yokusebenzisa ndawonye, ​​​​noma ngabe i-crucible iqhekeke ngephutha lapho impahla iphansi kunempahla, ngeke ithinte ukusetshenziswa, ingasetshenziswa ngaso sonke isikhathi, futhi asikho isidingo sokukhathazeka mayelana nolwelwesi. isithando somlilo, esingeke sithinte umsebenzi ojwayelekile. Ezinye izindleko aziphezulu. Kusukela yasungulwa, isheshe yathola inani elikhulu lamakhasimende e-alloy ngokusebenzisa ukudunyiswa komphakathi kwamakhasimende.
