A method and apparatus for optimizing melting of titanium for processing into ingots or end products. The apparatus provides a main hearth, a plurality of optional refining hearths, and a plurality of casting molds or direct molds whereby direct arc electrodes melt the titanium in the main hearth while plasma torches melt the titanium in the refining chambers and/or adjacent the molds. Each of the direct arc electrodes and plasma torches is extendable and retractable into the melting environment and moveable in a circular pivoting or side to side linear motion.

Method and apparatus for melting titanium using a combination of plasma torches and direct arc electrodes

A method and apparatus for alternating pouring into molds, casts or refining hearths from a common hearth in a furnace. The apparatus provides a main hearth, a plurality of optional refining hearths, and a plurality of casting molds or direct molds whereby the refining hearths and molds define at least two separate ingot making lines. The main hearth alternatively pours into a first ingot making line while the other line is prepared, and vice versa allowing for continuous melting.

A method for utilizing transformer capacity allows multiple transformer users to have ordered access to the same backup transformer. When one of the users requires the use of a transformer, the users in line ahead of this user must exercise their rights to use the transformer or pass on their rights allowing the next user to decide whether or not to use the transformer. The method allows transformer owners to offer extra transformer capacity to those who desire backups while protecting their ownership interest and their need for the use of the backup. The method also provides those who need backup transformers a system to obtain access to the required backup without requiring them to purchase a new transformer or to wait for the transformer to be built.

System and method for distributing transformer capacity among transformer users

A metal melting closed furnace which includes a main chamber, a circulation well connected to the main chamber by a communications passageway and a vortex well having a exit outlet for molten metal into the main chamber. A cover is emplaced over the vortex well. An inert gas bubble activated molten metal pump is provided in which there is an entry port in the circulation well and exit port into the vortex well. The exit port is positioned to lie at least partially or entirely above the maximum level of molten metal in the vortex well. This exit port will typically be at or near the top of the vortex well. In order to reduce oxidation, inert gas bubbles are captured from this molten metal pump and creating an inert gas atmosphere or blanket above the molten metal vortex.

Elevated discharge gas lift bubble pump and furnace for use therewith

A method and apparatus for optimized mixing in a common hearth in a plasma furnace. The apparatus provides a main hearth, a plurality of optional refining hearths, and a plurality of casting molds or direct molds whereby the refining hearths and molds define at least two separate ingot making lines. A feed chute provides raw material to the main hearth, whereby the feed chute is moveable to optimize its position during operation of the main hearth. Most particularly, the feed chute is moveable to provide better mixing, minimize skull build-up, and optimally place it opposite the overflow in use.
