aluminum alloy manganese additive tablets what are the usage

1, component analysis: metal powder + flux addition

2, metal powder: manganese: 75% - 80% - 85%

3, flux addition: A, no sodium flux B, aluminum powder C, flux + aluminum powder

4, shelf life: 8 months

Usage: - adjust the temperature of the molten aluminum above 730℃,the best temperature is not lower than 750℃.Preheating manganese tablet near furnace. after slagging –off from the surface of aluminum liquid, put the manganese tablet preheated into the aluminum liquid, and stir until reaction completely (about 3-5 minutes).In general, throwing ways should be adopted before refining, it is better to put in manganese tablet after the aluminum ingot melting and before putting silicon magnesium as far as possible, to ensure that melting diffusion time is enough for manganese.
