Atmosphere Controlled Induction Melting Granulating Casting Furnace 1500C 5kg Capacity

Product Overview

This high-performance thermal processing system is engineered for the sophisticated demands of modern metallurgy and material science. At its core, the equipment provides a robust platform for the auto-melting and casting granulation of various metal alloys. By utilizing advanced induction heating technology, this unit allows researchers and industrial processors to transform bulk metallic materials into precise spherical granules ranging from 1 mm to 6 mm in diameter. This capability is essential for creating high-purity alloy mixtures that are ready for secondary processes like ball milling or further specialized melting, ensuring a level of homogeneity and quality that traditional methods struggle to achieve.

The system is specifically designed for target industries involved in material development, precious metal recycling, and advanced aerospace components. This equipment functions efficiently in controlled environments, utilizing high-purity Argon gas to prevent oxidation and ensure the integrity of the alloy composition. With a maximum capacity of 5 kg, it serves as a bridge between laboratory-scale experimentation and pilot-line production. The furnace integrates melting, casting, and quenching into a single, cohesive workflow, streamlining operations for busy research facilities and specialized industrial foundries that require rapid turnaround times without sacrificing precision.

Built for reliability in demanding laboratory and industrial environments, the system features high-quality components designed to withstand repeated thermal cycling. The vacuum and atmosphere control subsystems are integrated to provide a stable operating environment, even when pushing the temperature limits of 1500ºC. Professional engineering ensures that every thermal cycle is predictable and repeatable, providing users with the confidence needed to conduct long-term research or high-value alloy production. This unit represents a critical investment for organizations seeking to optimize their thermal processing capabilities and advance their material science innovations.

Key Features

• High-Frequency Induction Heating: The equipment utilizes a powerful 20 kW induction output, facilitating rapid and uniform melting of metallic charges up to 5 kg. This method provides superior energy efficiency compared to traditional resistive heating and ensures thorough mixing of alloys through electromagnetic stirring.
• Precision Atmosphere Control: To protect sensitive alloys from oxidation, the system operates under a controlled Argon gas environment. This is complemented by an included double-stage rotary vane vacuum pump, allowing the chamber to be evacuated before backfilling with high-purity gas for maximum process cleanliness.
• Advanced PID Temperature Management: Equipped with a digital PID controller, the furnace maintains a temperature stability of ±2ºC. This level of control is crucial for maintaining the specific liquidus and solidus states required for high-quality casting and granulation.
• Integrated Granulation Module: The system includes a specialized graphite adapter with a 0.8 mm hole designed for water-quench granulation. This allows the user to directly produce spherical metallic granules, which are ideal for subsequent powder metallurgy or mechanical alloying processes.
• Bottom-Pour Casting Design: The crucible is engineered with a bottom-pour mechanism to ensure a direct and immediate transfer of molten metal to the casting chamber. This design minimizes the temperature drop during the transfer process, resulting in more consistent casting results and better structural integrity.
• Heavy-Duty Graphite Crucible Set: The system comes standard with a 750 ml high-density graphite crucible and a corresponding graphite rod for switching casting modes. These components are selected for their thermal shock resistance and low reactivity with most metallic alloys at high temperatures.
• Flexible Casting Chamber: The lower chamber accommodates flasks up to 5 inches in diameter and 9 inches in height. A swivel-out mechanism allows for easy insertion and removal, significantly improving ergonomic handling and reducing the risk of crucible damage during loading.
• Accurate S-Type Thermocouple: For critical monitoring, an S-type thermocouple is utilized, providing the most accurate readings across the entire operating range. This high-grade sensor ensures the PID controller receives precise feedback for real-time adjustments.
• Safety-First Pressure Regulation: The unit is designed with built-in monitoring gauges and manual release valves to manage internal chamber pressure. This ensures that the gas atmosphere remains within safe operating limits, preventing damage to the furnace components while maintaining the necessary inert environment.
• Industrial-Grade Water Cooling Interface: Designed for continuous operation, the system requires a 16L/min water flow to protect the induction coils and power electronics. This focus on cooling engineering ensures the long-term durability of the internal hardware even during prolonged high-temperature runs.
