Accurate Dosing and Temperature Control for Optimal Results in
Industrial Aluminum Melting Furnace
1.Operation principle of Aluminum alloy dosing & holding furnace
WDL pneumatic dosing furnace is designed to take metal below the
surface of the metal liquid
in the bath, which can avoid completely the oxidization slug and
tremendously imp rove the
quality of the alloy liquid.WDL pneumatic dosing furnace is
designed to feed directly and
automatically to the diecasting machine or gravity mold free of any
contamination.In order
to feed the alloy liquid, overpressure is formed inside the furnace
chamber .The level of alloy
liquid inside the rising tube is raised first until the alloy
liquid is about to overflow. When the
diecasting machine request the alloy liquid, the pressure inside
the furnace chamber will be
increased further in order for the alloy liquid to flow out. The
pressure will be decreased to end
the dosing once preset amount being reached.After dosing completed,
the liquid level is raised
back to the feeding level for the next dosing.

3. Pneumatic metering furnace
WDL Pneumatic Holding Furnace is the holding and dosing system for
the clear
and closed liquid aluminum,and is applied to aluminum.WDL Pneumatic
Holding
Furnace, ranging from 500KG to 4100KG, is applied to all kinds of
different types
of diecasting machine and the dosing, ranging from 0.5KG to 100KG,
can meet
almost all types of casting parts. The furnace adopts the most
advanced control
system of Siemens and is able to improve product quantity and
quality due to the
outstanding features of safe reliability, easy installation, simple
operation and
efficient dosing speed.
