Abstract
A furnace filtration system for improving the speed and efficiency of a molten metal centrifugal impeller pump contained within a non-ferrous molten metal furnace. The system includes a filtration well located upstream of the pump well. The filtration well includes a filter having a plurality of through filter passages that are sized to prevent any solid contaminants that are larger than the pump's impeller openings from passing therethrough. By preventing any contaminants that cannot pass through the pump, the pump can be run at a higher speed. A furnaces efficiency increases with the centrifugal pump's efficiency increases with its centrifugal pump's speed along with the flow and pressure. Increased flow and pressure increases a furnace's efficiency by a) increasing the melting rate; b) decreasing the energy lost by reducing the metal temperature stratification; and c) reducing the contaminants increases the quality of the metal produced while reducing the amount of nitrogen and chlorine needed to clean the metal.
