Usage Instruction of Cr Tablet

Before refining flux application, after alloying, the metal additives can be put into melting furnace or holding furnace directly. To achieve the high efficiency, the usage should match up the right notice as follows:

1. The temperature of the aluminium liquid not lower than 740℃. the best application temperature is 750+5℃
2. It is sinking down by itself. So keep the surface clean is very important, to avoid wrapped by the floating slag or the slag which floated on the surface. So it must be put into after drossing.
3. After skimming the dross, the tablet should be put directly in to the aluminium molten evenly with tablet please do not crush it.keep it stay for 20-30mintures, stir it and let it stay for 7-15 minutes. Sample analysis should be performed.

Dosage of Cr Tablet

Dosage=(Target-initial)*aluminium wt% /(90% * the alloy element content in the metal additives)
Target: element content of target
Initial: Original content of elements in the melt
Wt: The weights of aluminium melt
