摘要： An apparatus and method for filtering molten metal (M), such as aluminum or an aluminum alloy includes at least one ceramic foam filter or any other type of filtration media such as porous tube or alumina balls disposed in a receptacle (12) for the molten metal (M). A vibrator vibrates at least one of the filter, the receptacle (12) or the metal and may be used to induce priming, filtering and/or drainage of the filter. The vibrator may be retrofitted to an existing filter system and may be adjustable in frequency and amplitude. The vibration may be continuous over a given period or produced in a single shock.

摘要： A liquid containing receptacle having a filter is disclosed that in one form includes a nozzle. The filter includes a passage having a portion with a size that restricts the flow of a liquid there through unless sufficient pressure is applied to overcome a liquid and filter property such as surface tension. The pressure in the liquid at the filter can be varied by changing a gas overpressure above a surface of the liquid, changing a head height of the liquid, and/or changing the liquid and filter property, among possible others. In one embodiment the liquid containing receptacle can be used to contain a molten metal that is used in an investment casting mold. The molten metal can be selectively poured into a mold by selectively changing pressure of the molten metal at the filter or by changing the pressure at which molten metal flows through the filter.

摘要： A mass of solid aluminum carbide containing product is produced by a process in which a mixture is formed of an aluminum containing material and a carbonaceous material consisting of, containing or yielding carbon. Then the resulting mixture is heated to a temperature sufficient to react carbon of the carbonaceous material with the aluminum of the aluminum containing material to produce solid aluminum carbide. The solid aluminum carbide then is able to be heated with an aluminum compound selected from Al2O3, Al4CO4, AlO, Al2O and mixtures thereof, to produce aluminum metal and carbon monoxide.

摘要： 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.

摘要： A single treatment compartment has a liquid metal inlet and outlet and a connection to a liquid metal-input trough. A treatment gas is injected into the liquid metal arranged in at least one sidewall of a ladles. The liquid metal inlet and outlet have an orifice positioned so as to be entirely underneath a level of the liquid metal during the treatment, in order to prevent entry of ambient air into the compartment during treatment. The treatment compartment includes an upstream part and a downstream part. The gas injection is accomplished in the upstream part. The compartment further has a filter located in the downstream part for degassing and filtering the liquid metal. Injection and filtration occur in close proximity to one another and within the same single treatment compartment.
