Product Description

10ppi Silicon Carbide Foam Ceramic Filter For Aluminium Casting

Product Introduction
Silicone carbide foam ceramics use polyurethane foam sponge imported from Germany as a carrier, filled with silicon carbide, alumina, binder, additives and other fine powder mixed into slurry, and then extruded slurry, remaining coated in the foam fiber around the slurry, after drying, roasting and sintering at high temperature, polyurethane heat decomposition, leaving foam ceramic products, that is, silicon carbide foam ceramic filter.With the three-dimensional structure of the filter sponge, the silicon carbide foam ceramic filter can make the metal liquid reflect the rectification, mechanical screening, filter cake, adsorption and other filtration mechanisms to effectively improve the purity of the metal liquid, reduce the scrap rate and reduce machining losses, thereby improving production efficiency and reducing production costs.

Product Characteristics
Silicon carbide foam ceramic filter is mainly used for the filtration of ductile iron, gray iron, aluminum, copper, and other alloy castings, effectively removing large pieces in liquid metal
Inclusion, adsorption of fine magazines, reduce the content of gas and harmful elements in liquid metal, improve the metal matrix structure, improve the mechanical properties of castings.
1.Reduce the rejection rate of inclusion defects: inclusion defects are reduced by more than 50%.
2. Improve the machining performance of castings: tool life is increased by more than 30%
3. Improve the mechanical properties of castings: mechanical improvement of more than 10
4. Improve the casting process yield: increase the process yield by more than 10

Product aperture size selection
1. The choice of aperture: When using the foam ceramic filter, it is necessary to determine the quality requirements of the casting and the number of inclusions in the metal liquid to confirm the filter aperture (number of holes per inch of product, ppi) .Filter aperture is mainly divided into 10ppi, 15 ppi, 20ppi and 30 ppi specifications Product.Ductile iron parts generally use 10ppi or 15 ppi specifications, gray iron and cast copper parts generally use 10ppi, 15 ppi or 20 ppi gauges,aluminum alloy castings generally use products with 20 ppi or 30ppi specifications.
2. The choice of size: the thickness of the foam ceramic filter is larger, the strength of the filter is better, and the filtration efficiency of the filter is higher.The more expensive it is to use. Considering the most suitable strength and filtration efficiency,it is generally recommended as follows: size75mm,thickness20~22mm;size75-120mm, thickness 22~25mm;Size 120~150mm, thickness 25~30mm;Size 150mm, thickness 30~40mm.
The size of the foam ceramic filter should be determined by combining the type and size of the casting. The amount of liquid filtration of foam ceramic filter unit cross-sectional area of maximum gold should generally be controlled within the following range: ductile iron ≤2KG/CM; Gray cast iron, copper aluminum alloy castings ≤4KG/CM3. Conventional bubble foam ceramic filter size filtration amount is as follows:

 Product use method and placement
The foam ceramic filter can be placed in various parts of the pouring system, and should be selected according to the characteristics of the parts and production conditions, as close as possible to the casting to achieve the best filtration effect. In practical applications, according to different castings and requirements, the following methods can be used:
(1) Placed in the mold shell pouring cup: Reserve the filter table at the mold shell pouring cup, after the mold shell roasting, place the foam ceramic filter at the gate position, or bake and preheat the filter with the mold shell before pouring, which helps the metal liquid to begin to pass, and the use effect is better. In order to make the filter easy to place, it is necessary to design the filter base, that is, there is a 2 mm gap between the filter place and the outer edge of the filter in the shell, and the supporting surface should be left with a base greater than 5mm width.
