15KW Induction Melting System with Top Suction Casting for Thin Rod Production Up to 1200°C

Product Overview

This high-performance induction melting system represents a sophisticated solution for material science researchers and industrial laboratories requiring precision alloy fabrication. By combining 15KW of high-frequency induction power with an innovative top-vacuum-suction mechanism, the equipment enables the production of high-purity metal rods with exceptional structural integrity. The system is specifically engineered to address the challenges of traditional gravity casting, providing a controlled environment where molten metal is rapidly drawn into a specialized feeding tube to ensure uniform density and refined grain structures.

Designed for versatility and efficiency, this unit is widely utilized in metallurgical engineering, aerospace material development, and advanced manufacturing R&D. It serves as an essential tool for creating small-diameter alloy rods that require minimal post-processing and exhibit reduced defects. The integration of advanced thermal insulation and high-vacuum capabilities ensures that sensitive materials can be processed without contamination, making it ideal for the development of specialty alloys, rare earth metals, and high-performance composites.

Built with industrial-grade components and a focus on long-term operational reliability, the system provides consistent performance under demanding research conditions. From the robust stainless steel vacuum flanges to the high-efficiency water cooling circuit, every aspect of this equipment is designed to deliver repeatable results. Users can operate with high confidence, knowing the system includes comprehensive safety protections for water pressure, temperature, and power, ensuring both the operator and the delicate research samples remain protected during high-temperature cycles.

Key Features

• Precision Induction Heating Core: The system utilizes a 15KW power supply with an adjustable output frequency ranging from 30 to 80 kHz. This high-frequency capability ensures rapid and uniform heating of the melt, allowing for excellent homogenization of alloying elements within the crucible.
• Innovative Top-Vacuum-Suction Mechanism: Unlike traditional casting methods, this equipment employs a unique suction force generated by a manual syringe piston. This allows the molten metal to be instantly drawn upward into a quartz feeding tube, resulting in rapid solidification and the production of rods with significantly reduced shrinkage cavity defects.
• Controlled Cooling Dynamics: The rapid movement of the melt into the top quartz tube facilitates high-speed quenching. This process is critical for achieving specific microstructures and preventing the formation of large, undesirable grains in specialized alloy compositions.
• Advanced Thermal Management: The unit features a complete refractory assembly made of high-purity alumina. This multi-piece design includes a bottom crucible support, holder, and cover, ensuring maximum heat retention while protecting the internal components of the vacuum chamber.
• Vacuum and Inert Atmosphere Integrity: Equipped with a stainless steel flange system and high-temperature silicone O-rings, the furnace maintains a high-vacuum environment. Integrated needle valves allow for the continuous flow of protective inert gases, which is essential for preventing the oxidation of graphite crucibles and reactive melt materials.
• Real-Time Process Monitoring: A 12mm diameter observation window positioned on the top flange provides the operator with a direct line of sight to the melt. This allows for precise timing of the suction process based on the visual state of the molten material.
• Automated Cycle Control: The induction heater includes digital timers for automatic heating, dwelling, and cooling stages. Users can program specific cycles (1-99 seconds each) to ensure process repeatability across multiple experimental batches.
• High-Capacity Support Systems: The package includes a heavy-duty 156 L/min double-stage rotary vane vacuum pump and a dedicated 15-liter stainless steel water chiller. These auxiliary units ensure that the primary system remains at optimal operating temperatures and maintains the required vacuum levels throughout extended processing sessions.
