Ampy Pipe

A deep-bed filtration system is used to clean metal prior to casting and can achieve filtration efficiency of greater than 90 percent. These systems are frequently used in slab rolling ingot and continuous sheet casting processes. It typically is placed in between the holding furnace and the casting operation and consists of an outer steel shell with a refractory lining containing grid plates and layers of alumina balls.
We provide design, engineering, and manufacturing expertise to build Liner Systems that conform to specific assembly needs. Any size, shape, or configuration is possible for a turnkey solution.
Precision-cast baffles for the molten metal casting process are available to ensure optimal metal flow control.
Defined as an elevated platform in a bed filter to support the filter media and allow metal flow. These are custom designed and engineered for each individual specification with tight tolerances.
Our floats feature no outgasing, custom engineered shapes to meet any requirement, tight tolerance, and low density or fused silica refractory options.
Bed Filters (BF): Built of Al2O3-balls or chips (2 - 8 mm). These are suited for high throughput of melts up to 1000 t and separation of small inclusions < 20 μm.
Ceramic Foam Filters (CFF): Labyrintic structured ceramic material. Very effective cleaning via deep bed filtration effects. Available in various pore sizes (10 ppi to 80 ppi). These are the most commonly used in Aluminium metallurgy due to low operational costs.
Rigid Media Filters (RMF): Porous ceramic tubes built in pipe bundles. Best for removing very small particles, though they have a higher pressure drop and shorter lifetime.
