Product description
Function& application:
Used for melting and casting, to adjust the Si content in the alloy, is the best material to instead of Al –Si alloy..This product is small, fast melting (usually less than 5 minutes), easy to use, Its silicon content is above 95% and the efficiency is above 90%
Usage:,
1. molten aluminum temperature required: above740 °C, the higher the temperature, the higher the absorption rate.
2. dosage：
Required Si（%）- Original Si（%）×the weight of melt
95%×90%
1.It can be directly added to the melting furnace and better to use before refining , molten aluminum temperature required: 720-750 °C
2.Make an analysis about metal element on alloy before use, calculate inputs of additive according to demand and additive yield rate.
3.Removal off the packing, put the additive into the molten alloy evenly , close the furnace door and keep 20-30 minutes, and then stirring for 10 minutes and deslagging.
4. Secondly, adjusting temperature, 10 minutes later, stirring completely again, refining for 15 minutes and deslag to get needed alloy.
