MELTING PROCESS

Two melting furnaces, Gautschi type.

They are equipped with oil burners

and supplying the holding furnace with liquid metal.

Melting Process

The furnace's load is made of various solid raw material (aluminum, magnesium, copper ...)

The goal of the melting process is to transform various solid raw materials of various shapes (ingots, tablets ...) into liquid aluminum alloys.

Several operations are performed in the following order:

OPERATIONS

LOADING OF THE RAW MATERIAL

Raw materials are introduced in the furnace in a specific order to help the transformation of the solid state to the liquid state.

For example, pure aluminum is introduced first.

Loaded materials are mixed to help dissolve material together, to homogenize the temperature and composition of the load inside the furnace

STIRRING

Loaded materials are mixed to help dissolve material together, to homogenize the temperature and composition of the load inside the furnace.

SKIMMING

Material may contain oxides or impurities.

The skimming operation is to remove dirt from this liquid bath.

CHEMICAL ADJUSTMENTS

Once operations are performed, a sample is made and analyzed.

We are verifying the rate of each chemical element (copper, silicon, etc.) of the alloy with the required grid of chemical composition. According to this first results we can adjust the concentration of the melt charge.
