Habka dhalaalinta foornada dhalaalka ee aluminium-manganese master alloy induction

1. Si buuxda u kuleylka diyaarsan;

2. Ku dhalaali qiyaastii 75% aluminium galinta ee ku dhexjiray qolof garaaf ah oo ku kululee ilaa 900-1000℃;

3. Ku dar manganese dufcad. Ka dib markii qayb kasta lagu daro, si fiican ugu walaaq ul garaafyada. Ka dib dhalaalid, ku dar qaybta soo socota, oo ugu dambeyntii ku dar aluminium haray;

4. Kadib dhalaalid, ku dar wakiilka sifaynta ee ku saabsan 850 ℃ (qiyaasta waa in lagu daraa si waafaqsan shuruudaha, sida 0.5-0.8% ee wakiilka AWJ-3) ka dib markii daawaynta sifaynta degassing, ha u istaagaan 5-10 daqiiqo oo ku tuur xiniinyaha. Si looga hortago kala-soocidda manganese, ingot waa in si buuxda loo walaaqaa ka hor inta aan la shubin, iyo shubitaanka waa in la dhammeeyaa sida ugu dhakhsaha badan ( dhumucdiisuna ≤ 25mm).
