Embodiment 1
[0016] raw material:
[0017] Graphite powder 25%; NaF 20% (purity 99%);
[0018] Talc 20%; Borax 15%;
[0019] Cryolite 5%; Expanded Perlite 15%;
[0020] 1) Crush NaF, graphite powder, talcum powder, borax, expanded perlite, and cryolite until the particle size is less than 5mm;
[0021] 2) Mix the above materials evenly;
[0022] 3) Add the above-mentioned slag-accumulating agent (1Kg / t) to the magnesium melt with a composition of 99.9% before casting and removing slag, sprinkle the slag-accumulating agent evenly on the surface of the flux, and let it stand for 5 minutes;
[0023] 4) Carry out the slag removal treatment, most of the slag is lumpy, the melt and the slag are separated, the slag is very easy to remove, the whole slag removal process takes a short time and the process is simple.
Embodiment 2
[0025] raw material:
[0026] Graphite powder 15%; NaF 25% (purity 80%);
[0027] Talc 15%; Borax 20%;
[0028] Cryolite 2%; Expanded Perlite 23%;
[0029] 1) Crush NaF, graphite powder, talcum powder, borax, expanded perlite, and cryolite until the particle size is less than 5mm;
[0030] 2) Mix the above materials evenly;
[0031] 3) Add slag-accumulating agent (1Kg / t) before casting and removing slag of the magnesium alloy whose composition is AS31, sprinkle the slag-accumulating agent evenly on the surface of the flux, and let it stand for 5 minutes;
[0032] 4) Carry out the slag removal treatment, most of the slag is lumpy, the melt and the slag are separated, the slag is very easy to remove, the whole slag removal process takes a short time and the process is simple.
Embodiment 3
[0034] raw material:
[0035] Graphite powder 18%; NaF 23% (purity 90%);
[0036] Talc 18%; Borax 17%;
[0037] Cryolite 4%; Expanded Perlite 20%;
[0038] 1) Crush NaF, graphite powder, talcum powder, borax, expanded perlite, and cryolite until the particle size is less than 5mm;
[0039] 2) Mix the above materials evenly;
[0040] 3) Add slag-accumulating agent (1Kg / t) before casting and removing slag of the magnesium alloy whose composition is ZK60, sprinkle the slag-accumulating agent evenly on the surface of the flux, and let it stand for 5 minutes;
[0041] 4) Carry out the slag removal treatment, most of the slag is formed into blocks, the melt and the slag are separated, the slag is very easy to remove, the whole process of slag removal is short, the process is simple, and no toxic and harmful gas substances are produced.
