Indlela yokwelapha yokushisisa kwangaphambili kanye nokomisa yesithando somlilo esincibilikisa i-wave wave aluminium

Ngaphambi kokusebenzisa i-crucible entsha okokuqala, kungcono ukushisa i-graphite crucible amahora angu-4-24.

Ngaphambi kokusebenzisa i-crucible entsha, uma kungenzeka, faka izinkuni ku-crucible ukuze zishise amahora angu-2-4, okuwusizo ekunciphiseni umswakama we-crucible.

1 Ukushisisa nokushisisa ngaphambili kwesithando somlilo esisha sihamba kanje:

Imifantu ivela ku-crucible, ikakhulukazi ngaphambi kwama-degree angu-200. Ukunakwa okukhethekile kufanele kukhokhwe ukuze ungajahi, kodwa ukhuphule izinga lokushisa kancane kancane ngamandla obubanzi obuphakathi. I-crucible inenqubo yokuguquguquka. Gcina izinga lokushisa ku-150 ° C okungenani amahora angu-2, susa kahle umhwamuko wamanzi, ukoma ngokushesha noma ukushisa ngamandla amakhulu, okuzokwenza kalula ukuthi i-crucible iqhume. I-crucible iqhuba ukushisa ngokushesha okukhulu, futhi umsebenzi wokushisa wenziwa. Lapho i-crucible ifinyelela kuma-degree angu-300, ingashisa ngokushesha, futhi ngeke iqhume.

A. Ukushisa kwekamelo kuphakama ku-100 ° C, ukushisa kwamanje ku-15A, ibhodwe elingenalutho lishiswa ku-100 ° C ngaphandle kwesembozo, futhi izinga lokushisa ligcinwa njalo ku-2h;

B. Phakamisa izinga lokushisa lisuka ku-100℃ liye ku-200℃, izinga lokushisa lingu-20A, ibhodwe elingenalutho lishiselwa ku-200℃ ngaphandle kwesivalo, futhi izinga lokushisa lihlala lihlala ku-2h;

C. Phakamisa i-200℃ kuya ku-300℃, ukushisa kwamanje i-30A, i-crucible engenalutho ishisa ku-300 ℃ ngaphandle kwesivalo, izinga lokushisa elihlala njalo le-1h;

D. Phakamisa izinga lokushisa kusuka ku-300 ° C kuya ku-800 ° C, ukushisa ngomthwalo ogcwele, vala i-crucible engenalutho bese ushisa kuze kufike ku-800 ° C, gcina izinga lokushisa lingaguquki i-1h;

Ngalesi sikhathi, faka izinsalela ze-aluminium ezomile, bese wengeza kancane kancane ama-ingots e-aluminium ngebhodwe elinguhhafu lamanzi e-aluminium. Izinga lokushisa elingenhla libhekisela ekushiseni kwesithando somlilo (ngaphakathi kwesithando somlilo).

Qaphela: Izinga lokushisisa lifika ku-400℃/ihora. Ukushisa kuqala kusho ukuthi i-crucible akumele ilayishwe ize ibe bomvu, futhi i-crucible kumele yome.

2 Ngemva kokumisa isithando somlilo, khafula isobho ngokuhlanzeka ngangokunokwenzeka, vala ikhava yesithando somlilo, bese uvala izimbobo. Ukugcina izinga lokushisa elisele.

3 Ngemva kokumisa isithando somlilo, lapho usebenzisa i-crucible futhi, bheka uhlelo olulandelayo lokubhaka.

Uma isithando somlilo sivaliwe izinsuku ezingu-1-3, cindezela i-preheating ABC ukuze uhlale ungashintshi, futhi ushise i-crucible kuze kube yilapho i-crucible ibomvu, bese wengeza okomile okomile kwe-aluminium impahla.

Uma isithando somlilo sivaliwe isikhathi esingaphezu kwezinsuku ezingu-7, sebenzisa njengokushisa kokuqala kwebhodwe elisha.

4 Uma i-crucible entsha ivulwa ukuze ihlolwe futhi ingasetshenziswa, kufanele ihlanganiswe uphawu lwayo lwangempela futhi akufanele ibekwe esithandweni somlilo esincibilikisa igagasi le-aluminium ukuze kugwenywe ukuswakama. Uma i-crucible inomswakama ngesikhathi sokusetshenziswa, i-crucible kufanele ihanjiswe yisithando somlilo ukuze sishise amahora angu-8-24 , Bese ufaka izinkuni ku-crucible ukuze zishise amahora angu-2-4, bese ushisa kuqala ngendlela engenhla.
