Detailed introduction
NEW Advanced PID-controlled electric melting furnace for aluminum ingots & runners · Capacity 130–1000 kg
Equipment Application
The crucible electric aluminum melting furnace is primarily designed for melting and holding aluminum ingots and runners. It operates on the principle of resistance heating, which radiates uniformly to the crucible. Once the crucible reaches the set temperature, operators can load aluminum ingots or runners into the crucible to begin the melting and holding process. This electric aluminum melting crucible furnace is widely used in aluminum and zinc alloy die-casting and foundry industries.
Main Features
Dual temperature control (chamber + molten aluminum): Equipped with a thyristor power module and PID phase-shift triggering control system. The aluminum melting furnace with crucible uses online self-tuning to compute optimum PID parameters, achieving ideal temperature uniformity and power regulation for demanding process requirements.
Double-layer brick & fiber composite insulation: Inner lining built with high-temperature aluminum silicate fiber folded blocks, backed by high-temperature fiber blankets and nano-plates. Total insulation thickness > 300 mm significantly reduces heat loss. Surface temperature ≤ 45 °C (except furnace mouth) – a key advantage for energy saving aluminum melting furnace designs.
Silicon carbide (SiC) crucible: The furnace adopts a silicon carbide crucible aluminum melting solution which offers excellent thermal conductivity, extended service life, and no contamination of the molten aluminum even after prolonged use.
High-temperature heating elements (Cr27Al7Mo2): Heating strips made of Cr27Al7Mo2 alloy are securely fastened to the fiber lining with high-temperature ceramic anchors. This design ensures large heating area, rapid heat-up, and long operational life – ideal for aluminum alloy melting furnace applications.
Eco‑friendly & energy‑efficient design: Optimized furnace structure and advanced insulation materials minimize thermal losses, improving electrical energy utilization. As a crucible furnace for aluminum casting, it uses electricity as the sole energy source – clean, low‑emission, and aligned with green manufacturing principles.
Enhanced safety system: In addition to the standard leak detection alarm, the PID controlled aluminum furnace includes over‑temperature protection, ground‑fault protection, and an emergency stop button for instant power cut‑off in critical situations. Warning signs around the furnace body further improve workplace safety.
Summary: Through continuous innovation, this crucible electric aluminum melting furnace not only preserves its original efficiency and durability but also achieves significant improvements in intelligence, environmental sustainability, safety, and user‑friendliness. It delivers a superior production solution for aluminum and zinc alloy die‑casting and foundry operations.
