Silica mesh casting filter is weaved by high silica fiberglass yarn and coated with special refractory coating. It can effectively remove slag, refractory particles and non‐metallic inclusions from molten metals.
Made from specially treated silica yarns, the refractory cloth filter silica mesh are capable of withstanding pouring temperatures up to 1620℃. Silica mesh filters are ideal for in‐mold filtration of gray, malleable, white, ompacted graphite and ductile cast irons, as well as non‐ferrous aluminum and copper‐based metal alloys and many types of small scale steel casting filtration.
In mold filtration including sand casting, gravity casting, shell mold casting etc.
The silica mesh casting filter can be located anywhere within the pouring system. The best results are obtained when the refractory cloth filter is placed as close as practical to the ingate.
Sectional Area of filter = Sectional Area without filter / (a x b)
a: Filter open area:50-60%
b: Filtration efficiency: 60-80%
So the sectional area with the filter is normally about 2-4 times that without a filter.
1.5x1.5mm, 2.0x2.0mm, 2.5x2.5mm, 3.5x4.0mm
