Direct Pour System
Introduction :
ACEFEED-DP is a combination of Ceramic Foam Filter (VUKOPOR)& Insulating Sleeve. It is used for Cast Iron, Aluminium, Copper Base alloys & Steel.
Mechanism:
ACEFEED-DP Mechanism takes place in two stages.
1) Filtration:
The Filtration effect is due to the mechanical entrapment of inclusions. The change in flow & pressure through the filter causes the contaminants (Inclusions) to stick to the filter labyrinth (Web of pore).
VUKOPOR Filter has maximum open pore structure (minimum internal blockages). This enhances the filtration efficiency & flow rate. It also reduces entrapment of air bubbles into the metal downstream. It changes Turbulent flow to a Laminar flow. It also reduces the oxide formation within the filter.
2) Feeding :
Once Filtration takes place Ceramic Foam Filter floats at top & Feeding action starts. Feeding effect is due to nature of both highly Insulating & high refractoriness 1400-1500OC of the Sleeve. It improves the temperature gradients within the castings & promotes the Directional Solidification.
