In a metal melting and temperature-raising supply system, a melting apparatus heats a metal material that is in a solid state and changes the metal material to a molten metal that is in a liquid state. A temperature raising apparatus includes a heat-resistant container that houses the molten metal produced by the melting apparatus and a temperature-raising heating unit that heats the molten metal housed in the heat-resistant container. A molten metal supply apparatus provides the molten metal to an external processing equipment in a state in which a temperature of the molten metal heated by the temperature raising apparatus is maintained. A control apparatus controls an amount of metal material in the solid state changed to the molten metal by the melting apparatus and supplied to the heat-resistant container, based on an amount of molten metal supplied to the external processing equipment from the molten metal supply apparatus.

In an aspect, a method of manufacturing a high purity copper-based alloy comprises providing in a melting furnace a feedstock and melting the feedstock. The method additionally includes bubbling an inert gas into the molten copper-based alloy to form the high purity copper-based alloy. Aspects are also directed to an apparatus and a method of fabricating an apparatus for manufacturing the high purity copper-based alloy.

A coreless induction furnace that is automatically adjustable during assembly operations or melting operations. The furnace may include an outer shell, a set of adjustable shunt systems that operably engages with the outer shell, at least one cooling coil that operably engages with the set of adjustable shunt systems, and a power coil that operably engages with the at least one cooling coil and the set of adjustable shunt systems. The furnace is configured to automatically adjust at least one shunt of the set of adjustable shunt systems relative to at least one of the at least one cooling coil and the power coil. The furnace may also include an adjustable head system that operably engages with the outer shell. The adjustable head system is configured to automatically adjust a head of the adjustable head system relative to the at least one cooling coil and the power coil.

The present invention relates to an electric dry hearth melter furnace designed for efficient and controlled metal melting. The furnace features a half-crucible chamber with an embedded heating element, ensuring direct heat transfer for improved energy efficiency. A refractory cover and insulation minimize heat loss, while a discharge outlet with an integrated filter reduces slag contamination. Adjustable support legs and an automated tilting mechanism facilitate controlled metal flow. A thermocouple and power control system regulate temperature, optimizing performance. The furnace's batch-loading system eliminates repeated heat cycling, enhancing metal purity and reducing oxidation. Its modular design accommodates various foundry scales, providing a cost-effective and safer alternative to conventional gas-fired and continuous melting systems. The invention offers precise temperature control, reduced operational costs, and an improved melting process, making it ideal for small to mid-sized foundries seeking efficient metal processing solutions.
