Mg remove Flux

Description

Mg remove Flux-sumetech,Magnesium Remover Flux,

magnesium remover flux is developed for removing unwanted minor amount of magnesium from molten aluminium and aluminium alloys. Initial magnesium content should be below 1%. If the initial magnesium content is above 1% add sufficient magnesium- free metal to bring it down to this level.

Usage

1> To remove 1 kg Mg in aluminum alloy , needs 5kg Special Flux ( in average )

2> Dosage =( Mg content in aluminum alloy %- needed Mg content %)* weight of molten aluminum *( 5±0 . 5kg)

3> Check the composition of molten aluminum and calculate the dosage as the formula ( NO . 2 )

4> Application temperature : 735 ℃ -- 745 ℃.

5>Spray special flux with high purity nitrogen into furnace twice and make sure full access .

Firstly , take half of special flux to refine 20 - 25minutes , then deslag .

Secondly , use the rest specila flux , refine 15 - 20minutes , then deslag .

At last ,close the furnace door and keep 10 minutes
