A method of treating molten aluminum containing a suspension of finely divided salt particles remaining after filtering molten aluminum is disclosed. The method comprises providing a body of molten aluminum containing the suspension of molten salt particles entrained therein and passing the molten aluminum into a medium substantially unwettable by the molten salt particles. The particles of salt are collected on the medium and permitted to agglomerate so as to be removed to the surface of the mo...

A method for making molten iron includes the steps of feeding a raw material mixture containing an iron oxide material and a carbonaceous reductant into a heating reduction furnace to reduce iron oxide in the raw material mixture with the carbonaceous reductant into solid reduced iron; transporting the solid reduced iron to a melting furnace; and combustion of a carbonaceous material supplied as fuel to melt the solid reduced iron in the melting furnace for producing molten iron. After the metal...

The basic shape of the molten glass fining apparatus of the present invention is preferably either an elliptical or a somewhat rectangular shape such that the flow is more uniform and the bubbles have less distance to rise to the surface. A novel baffle design is also shown. The present invention improves the fining capability of the apparatus without increasing the cost of construction materials. In fact, the cost may be reduced.

An atomizer includes a T-shaped chamber with tapered insides and an outlet which is in communication with the chamber. A first path is located in a center area in the chamber so as to introduce molten metal therein and two second paths are introduced into the chamber so as to send inert gas into the chamber. A separator is located in the chamber and located at an outlet end of the first path. A narrow passage is defined between an inside of the outlet and the separator. The impact of the inert g...

The invention provides an internal filter with an improved filtering ability of removing particularly fine inclusion particles from molten aluminum or molten aluminum alloy. The internal filter includes an aggregate meshed member made of a refractory material and a coating layer formed on a surface of the aggregate meshed member. The coating layer contains a soda silicate that is able to be softened or viscous at a temperature of the molten aluminum alloy.

A castable and machinable alloy suitable for submersion in a molten magnesium or magnesium aluminum melt has the following composition: The alloy is resistant to dissolution by the melt at temperatures of up to around 1800.degree. F.

An apparatus for processing molten material into a desired shape comprises a die or mold forming a cavity to receive molten material and to allow its solidification within the cavity. A source of vacuum is connectable to the cavity for sucking air out. A hollow after-pressure cylinder is in communication with the cavity so as to receive a portion of the material. The after-pressure cylinder has a first end for connection to the cavity, and a second, opposite end. In the region of the second end ...

An apparatus for the delivery of molten metal includes a container that is pivotably supported by a transportable support structure. An actuator mounted upon the support structure and connected to the container is operable to pivot the container relative to the support structure.

A container for molten metal which uses heat of solidification for heating the molten metal.

A tool or fluxing head for fluxing molten metal that comprises a fluxing gas supply line that communicates with the interior of an inverted plunger cup providing a hollow interior into which refining agents and other additives that are to be introduced into a molten metal can be incorporated. In use, the fluxing head is introduced into a molten metal body with the plunger cup in the inverted position. The inverted plunger cup has a closed top at the point where the gas supply line enters and an ...
