High Pressure Induction Melting Casting System 1700C Max for Alloy Granulation and Infiltration Equipment

Product Overview

This high-pressure induction melting and casting system represents the pinnacle of thermal processing technology for modern metallurgy and advanced material science. Designed to facilitate melting, casting, and infiltration processes under extreme conditions, this system allows researchers and industrial engineers to process alloy samples up to 2 kg at temperatures reaching 1700ºC. By maintaining an internal environment of high-pressure Argon gas up to 1 MPa (10 bars), the equipment effectively suppresses the volatilization of high-vapor-pressure elements, ensuring that the chemical integrity of sensitive alloys remains intact during the heating cycle. This capability is essential for the development of high-entropy alloys, aerospace-grade materials, and specialized industrial components.

The equipment is specifically engineered for high-performance applications, including the granulation of exotic alloys, the separation of melt from slag, and the creation of advanced metal matrix composites through melt infiltration. The dual-chamber architecture, featuring a top melting zone and a bottom casting zone, enables seamless transitions from liquid phase to solid state under controlled atmospheric parameters. This versatility makes the unit an indispensable asset for facilities focused on semiconductor research, nuclear material development, and high-performance manufacturing sectors where purity and structural consistency are paramount.

Built for reliability in demanding environments, the system features a heavy-duty SS304 stainless steel chamber equipped with a high-efficiency water-cooling jacket. This engineering choice ensures that while internal temperatures may exceed 1700ºC, the external surface remains safe to the touch, preventing thermal fatigue of the vessel and protecting operators. The integration of precision induction heating with advanced pressure management systems provides users with the confidence to execute complex thermal profiles repeatedly without compromising equipment performance or safety. Each component, from the high-purity alumina refractory to the graphite crucible assemblies, is selected for its ability to withstand rapid thermal cycling and high-pressure differentials.

Key Features

• Precision Induction Heating Power Source: The 25 kW induction system operates at a high frequency of 30-80 kHz with a 100% duty cycle, providing efficient and rapid heating through electromagnetic coupling. This allows for precise control over the stirring effect in the melt, ensuring chemical homogeneity across the entire charge.
• High-Pressure Processing Environment: Capable of operating at a maximum working pressure of 1 MPa (10 bars), the system utilizes inert gas atmospheres to facilitate specialized processes like melt infiltration or to prevent the oxidation and evaporation of volatile alloying elements at extreme temperatures.
• Dual-Chamber Modular Design: Featuring a primary melting chamber at the top and a dedicated casting chamber at the bottom, the architecture allows for gravity-fed casting or pressure-assisted infiltration. This layout maximizes throughput and minimizes the risk of contamination during material transfer.
• Advanced Water-Cooled SS304 Construction: The melting chamber is fabricated from industrial-grade SS304 stainless steel with a double-walled water jacket. This design maintains the external shell temperature below 60ºC, significantly enhancing operator safety and the structural longevity of the pressure vessel.
• Sophisticated PID Temperature Control: An integrated digital controller offers 30 programmable segments, providing automated control over heating rates, soak times, and cooling curves. Utilizing a Type-B thermocouple, the system maintains a stability of ±5ºC to ensure repeatable experimental outcomes.
• Comprehensive Refractory Protection: The internal assembly is protected by high-purity fibrous alumina insulation and a complete refractory set. This protects the induction coil and the stainless steel chamber from the intense radiant heat of the crucible, optimizing energy efficiency and reducing thermal loss.
• Fast Heating Response Rates: Engineered for speed, the induction system can achieve heating rates of 4ºC/second between 1000-1200ºC and up to 2ºC/second in the critical 1500-1700ºC range, allowing for rapid alloy development and reduced processing times.
• Integrated Safety and Overpressure Protection: The unit is equipped with a safety release valve and a protective cover to manage high-pressure operations. Additionally, automatic interlocks monitor water pressure, over-temperature conditions, and power surges to prevent equipment damage during unexpected events.
• Versatile Crucible and Tooling Options: Standardized for 1000g Fe-based alloy capacity, the system includes high-purity graphite crucibles. The bottom of the crucible is specifically sealed from the casting chamber to maintain pressure differentials, with options for customized grain-making or infiltration tooling.
• Industrial Casting and Vacuum Capability: The bottom chamber includes a digital vacuum gauge and is supplied with a double-stage rotary vane vacuum pump reaching 1bar (-29.9" Hg), facilitating clean-room quality casting environments free from atmospheric contaminants.
