Aluminium

Dear all

We are doing Development for melting turning and milling scarp.

Process Called:

Aluminum melting process

Turning and milling scarp Melting process

Spec:

Aluminium Thickness: 0.05mm

Density :90kg/m3

Normal Process:

If we melt directly with crucible or refractory furnace 30% will burn out to oxide and become a dross

Spec:

Aluminium Thickness: 0.05mm

Density :90kg/m3

Normal Process:

If we melt directly with crucible or refractory furnace 30% will burn out to oxide and become a dross.

our aim:

To get 83% of yield in aluminium so that we used a chemical for melting

Process :

In a refractory furnace melt following salt

Sodium Choride

Merato Potash

Calcium floride (or) florospar

In a molten salt bath immerse the turning after pre heating 200'C.

Problem We faced :

a)After melting salt to liquid stage we added aluminium scarp,as soon as we added aluminium scarp.salt bath become semi solid.

The requirement for us, chemical should with stand 700'C mean while it should not react with aluminium and it should be stable.So that every time we add aluminium in furnace it should comes out in outlet value,But the chemical should be stable. the density of aluminium is higher then salt we feeding inside the furnace.So the aluminium goes under the salt so there will no be dross.But we failed in trail.kindly do the needfull for us

Pls suggest a suitable economical salt for this process.
