NON-METALLIC NET FILTERS FOR FILTERING METAL IN LOW PRESSURE
-
The fiberglass filter does not pollute and does not change the composition of the liquid aluminum alloy at high temperature.
-
The weight of the fiberglass filter is lighter than the galvanized metal mesh, it can thus float on the surface of the liquid aluminum and be removed without any pollution of the alloy.
-
With the glass fiber filter, the operator can obtain a good separation of the liquid aluminum very easily and can be reused, on the contrary, of what happens with the galvanized wire mesh.
SOLUTION FOR QUICK RELEASE OF JET METEROZZES
Cutting the casting of the casting has always been a difficult and risky operation, which few foundry operators like to practice. A good solution to reduce the TIMES and RISKS is to use fabric filters (filtering net with 4x4 mm hole which still allows a good passage of the metal flow), to be positioned in the casting system as close as possible to the jet.
The application of the filter in the vicinity of the jet creates an area of torrence between jet and weather, while ensuring a good flow of metal feed (a mesh with a 2.5x2.5 mm wide hole is used) which with
a hammer blow generates the detachment of the meteor from the jet, without having to cut it with other tools, which are difficult and dangerous to manage, thus making the detachment of the meteor from the jet easier and faster.
The use of silica fabric filters, to help the rapid breakage of the bad weather, can be applied with the following solutions:
-
insertion of the filtering net into the mold without any added locking system
-
in combination with a core of tips to fix the mesh filter in the bracket to the ground, allowing a uniform fracture surface, which does not cause a jagged surface, without risks that the mesh filter can enter the jet
-
applied to additional feeding systems (insulating and exothermic sleeves) fixed with points at the end near the jet, or by inserting in a section of the sleeve.
Application fields:
The filtering net can be used, in different qualities for the type of metal temperatures:
-

GRAPHITE FOAM FILTERS
Main features:
The ceramic foam filters are designed for the filtration of aluminum and aluminum alloys up to a temperature of 850 ° C, in particular for gravity casting in sand, ceramic or metal matrices.
A typical feature of foam filters is the three-dimensional network of open pores that form a labyrinth in their ceramic body.
The filters have a homogeneous ceramic structure.This design optimizes their filtering capacity and pouring rate. Their chemical composition, in contact with the adhesion forces active inside the ceramic filter, is ideal for capturing inclusions and base oxide films of Al2O3.
Recommended application:
The ceramic foam filters can be used in different positions within the casting system and applied in combination with insulating sleeves or exothermic sleeves. The filters can be equipped with a sealing gasket to prevent them from crumbling in positioning inside the mold and to guarantee an excellent seal during the passage of the liquid metal.
Benefits found:
Better casting quality:
-
Better quality of the casting surface.
-
Improvement of the mechanical properties of the castings.
-
Better precision of the dimensions and shapes of the jets.
Cost reduction:
-
Small amount of waste.
-
Reduction of the costs of finishing operations.
-
Simpler design and casting system.
Special features:
The biggest advantage of graphite filters compared to other types of filters are their low density, which provides the possibility of easier recycling of metals without excess work, and their high thermal conductivity, which allows a very rapid ignition of the filter by the start of the jet.
The low abrasiveness of the filters prevents damage to the work tools
in finishing operations (in case of closing of the closing system
filter).
