Melting txheej txheem ntawm aluminium-manganese master alloy induction melting rauv

1. Siab preheat tus nqi npaj;

2. Melt txog 75% ntawm txhuas ingot nyob rau hauv ib tug graphite crucible thiab overheat nws mus rau 900-1000 ℃;

3. Ntxiv manganese rau hauv batch. Tom qab txhua batch ntxiv, do kom huv si nrog ib tug graphite pas nrig. Tom qab melting, ntxiv batch tom ntej, thiab thaum kawg ntxiv cov seem aluminium;

4. Tom qab melting, ntxiv cov refining tus neeg sawv cev ntawm txog 850 ℃ (qhov ntau npaum yuav tsum tau ntxiv raws li qhov yuav tsum tau, xws li 0.5-0.8% ntawm AWJ-3 refining agent) tom qab degassing refining kho, cia nws sawv ntsug li 5-10 feeb. thiab pov lub ingot. Txhawm rau tiv thaiv kev sib cais ntawm manganese, lub ingot yuav tsum tau nplawm tag nrho ua ntej nchuav, thiab lub ncuav yuav tsum tau ua kom tiav sai li sai tau (ingot thickness ≤ 25mm).
