Industrial Aluminum Melting Furnace for Clean and Contamination Free Alloy

Product Specification

Industrial Aluminum Melting Furnace for Clean and Contamination-Free Alloy Liquid Production

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.

2. Technical Requirements
