Attention: Aluminium Alloy Manufacturers

Aluminium alloy business is no more profitable if done in a traditional way. In advanced countries, alloy makers are using latest technology. They are having large capacity furnaces, wherein melting furnace & alloying furnace are separate. Raw material is melted in “melting furnace” and then transferred to “holding furnace”. Addition of alloying metals is done in “holding furnace”. Correction, if required, is also done in “holding furnace”. In this process, there is no iron pick-up & segregation problem. They are using molten metal transfer pump for proper mixing & melting. Some manufacturers are using permanent magnetic stirrer system which mixes the alloy thoroughly. Thus alloy is homogeneous.

In India, mostly melting & alloying is done in one single furnace of small capacity say 05 to 10 tonnes per batch. Sometimes, there are chances of iron pick-up & segregation. It is advisable to make batches within a shortest time, so that oil consumption is low and recovery is high. At the same time, proper degassing with nitrogen gas is a must. For better alloy structure, we have to use refiners & modifiers. Alloy ingot design should be attractive & pallets should be tight & look attractive.
