500KG-4100KG Capacity Aluminum Alloy Dosing And Holding Furnace For All Types Of Casting

500KG-4100KG Capacity Aluminum Alloy Dosing and Holding Furnace for All Types of Casting

1. Description of 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

isable to improve product quantity and quality due to the outstanding features of safe

reliability,easy installation, simple operation and efficient dosing speed.

2. Operation principle of Aluminum alloy dosing & holding furnace

WDL pneumatic dosing furnace is designed to take metal below the surfaceof the metal

liquid in the bath, which can avoid completely the oxidization slug and tremendously improve

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.
