A crucible device with temperature control design includes a crucible body, an induction coil unit, a nozzle flange body and a melt delivery tube and a temperature control unit. The induction coil unit surrounds the crucible body, provides a heat source during use, and is configured to enable a metal material to melt and produce a melt having a melting skull. The melt delivery tube is communicated via the nozzle flange body to a bottom of the crucible body and is configured to deliver the melt from the crucible body. The temperature control unit includes a microprocessor, a heater and a temperature sensor which are electrically coupled to each other, and are configured to control a curve of the melting skull to drop to a preset position.

In production of a reactive metal using a melting furnace for producing metal having a hearth, ingots can be efficiently produced by efficiently cooling the ingots extracted from the mold provided in the melting furnace. In addition, an apparatus structure in which multiple ingots can be produced with high efficiency and high quality from one hearth, is provided. A melting furnace for producing metal is provided, the furnace has a hearth for having molten metal formed by melting raw material, a mold in which the molten metal is poured, an extracting jig which is provided below the mold for extracting ingot cooled and solidified downwardly, a cooling member for cooling the ingot extracted downwardly of the mold, and an outer case for keeping the hearth, the mold, the extracting jig, and the cooling member separated from the air, wherein at least one mold and extracting jig are provided in the outer case, and the cooling member is provided between the outer case and the ingot, or between the multiple ingots.

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.
