In the modern aluminum alloy casting industry, energy conversion efficiency and temperature control precision directly impact production costs and product quality. This case study analyzes the WDL-KGPS-1500 aluminum induction melting furnace (hydraulic tilting), highlighting its technical advantages and operational parameters at the 800KW power level.

1. Core Electrical Performance and Energy Conversion

The essence of induction melting lies in the optimization of electromagnetic induction efficiency and power factor.

• High Power Density Solution: The system is configured with 800KW rated power, adapted for 440V/60Hz industrial power. Utilizing parallel rectification and inversion technology, it ensures a 100% startup success rate.

• Melting Efficiency Indicators: For a rated capacity of 1.5 tons (maximum 1.8 tons) of aluminum, the melting time per furnace is only 70±5% minutes, with a stable tapping temperature of 780°C.

• Power Factor Optimization: The power factor is maintained at ＞0.9, effectively reducing reactive power loss and enhancing energy utilization.

2. Structural Design and Durability Configuration

Strict industrial standards are applied to material selection for high-temperature melting environments.

• Induction Coil Craftsmanship: Utilizes T2/TU1 grade high-purity electrolytic copper with a thickness of 5mm. The high-conductivity coil, combined with optimized inter-turn insulation, ensures strong electromagnetic conversion and long-term mechanical strength.

• Hydraulic Tilting System: Equipped with a dual-cylinder drive, providing a tilting range of 0 to 95 degrees. Controlled via a manual valve, it offers stable performance without shocking or crawling, and can stay at any position to ensure safe and precise pouring.

• Lid and Crucible Module: The furnace lid uses hydraulic or mechanical rotation for flexible opening; the crucible module is formed by 3mm iron plate bending and welding to precisely control the refractory lining's shape and volume.

3. Water Cooling System and Safety Redundancy

A stable cooling cycle is a prerequisite for the continuous operation of high-power equipment.

• Classified Water Management: The system features independent water supplies for the power source (required flow ≥20 m³/h) and the furnace body (required flow ≥25 m³/h), ensuring sensors and silicon components remain within safe operating temperatures.

• High-Performance Water-Cooled Cables: Made of T2 multi-strand copper wire encased in high-strength fire-resistant rubber tubing. Cold-formed connectors ensure excellent contact and tensile strength during high-current transmission.

• Noise Control Standard: Through optimized electromagnetic frequency design, the operating noise is strictly controlled below 80db, complying with modern industrial health standards.

Technical Specifications Summary

• Melting Capacity: Rated 1.5 Tons (Aluminum), melting time 70±5 mins/batch.

• Electrical Configuration: 800KW power, 600-1000Hz frequency, power factor >0.9.

• Core Materials: 5mm thick T2 copper coil, hydraulic tilting angle 0-95°.
