STAR Molten Metal Treatment System
The STAR™ is a mobile or stationary rotary degassing system for aluminium foundries and diecasters, available in many models. In spinning-rotor degassing/fluxing systems, a metered amount of inert gas and/or flux is injected into the molten aluminium through the rotating graphite shaft and rotor. The STAR rotor shears the inert gas into tiny bubbles and disperses them evenly throughout the melt. Unwanted hydrogen gas and non-metallic inclusions are attracted to the inert gas bubbles and rise to the surface. The flux injection allows a steady flow of flux below the metal line which promotes oxide entrapment. The combined effect of gas injection and fluxing helps improve the quality of aluminium alloys and reduces overall operating costs.

Heated Cover Systems
Heated cover systems incorporate heaters as modules in trough cover sections, furnace lids, crucibles, filter boxes, low pressure diecast covers, holders, etc. Heated covers allow for the preheat of refractories prior to the introduction of metal, to retain the metal’s heat during transfer, and to hold the molten metal at temperature during periods of inactivity. In addition, the heated cover system keeps refractory surfaces hot, thus avoiding refractory thermal shock.

Bonded Particle Filter (BPF)
The unique Pyrotek Metaullics® bonded particle filter (BPF®) is especially useful in aluminium gravity casting (permanent mold), pressure diecasting, low-pressure, squeeze cast, and high-performance sand foundries to remove inclusions. It is used in both melting and casting furnaces where sustained use of one to four months per filter is typical. The above picture shows various aluminium castings that benefit from filtration. Bonded particle filters are produced from high-purity silicon carbide aggregate, and feature excellent strength for better handling; great durability and chemical resistance for long life; high thermal conductivity to minimize thermal gradients; greater filtration efficiency through a complex internal structure; and proven cost-effectiveness.
