Benchtop Micro Vacuum Induction Melting Furnace for Alloy Refining and Material Science Research

Product Overview

This benchtop vacuum induction melting system represents a state-of-the-art solution for high-temperature metallurgy and advanced material science research. Designed for laboratories, universities, and industrial research facilities, the system excels at melting, refining, and casting metals, alloys, and non-metallic materials under high-vacuum or protective gas environments. Its compact, horizontal front-opening benchtop design combines a modern aesthetic with functional, space-saving engineering, making it an ideal choice for research environments where space is at a premium but performance cannot be compromised. The system provides a controlled environment that is essential for preventing the oxidation and contamination of sensitive materials during high-temperature operations.

The core value proposition of this thermal processing equipment lies in its capability to perform rapid melting and precise casting in a single, controlled cycle. By integrating a high-frequency induction heating unit with a manual tilting mechanism, operators can melt sample charges ranging from 50 to 200 grams and pour them directly into ingot molds without breaking the vacuum or exposing the melt to ambient atmosphere. This capability is critical when working with reactive elements, such as titanium, aluminum, and rare-earth metals, which would otherwise oxidize or form unwanted inclusions under standard atmospheric conditions. The electromagnetic induction field also generates a natural stirring action in the liquid pool, ensuring complete chemical homogeneity throughout the entire sample.

Reliability and safety are fundamental to the design of this melting unit. The chamber is manufactured from premium-grade stainless steel and features a double-walled, water-cooled jacket that ensures the outer surface of the furnace remains safe to touch, even during continuous operations at temperatures exceeding 2000°C. Coupled with real-time temperature tracking via a non-contact infrared pyrometer and a visual simulation panel that displays the real-time status of all valves, pumps, and power settings, this equipment offers unmatched process repeatability. Operators can execute demanding experimental procedures with complete confidence, knowing that the system's thermal performance and safety systems are engineered to meet the rigorous standards of modern research laboratories.

Key Features

• Ultra-Fast Heating and Melting Cycle: Utilizing high-frequency induction heating technology, this system can achieve full melting of metal charges in less than 10 minutes. This rapid processing capability is crucial for high-throughput material screening, allowing researchers to evaluate multiple alloy formulations in a single day while minimizing energy consumption and thermal stress on the system components.
• Extended Thermal Range Configurations: The furnace is engineered to accommodate three distinct temperature ranges—500°C to 1700°C, 800°C to 2000°C, and 1000°C to 2400°C. This allows laboratories to select the configuration that best matches their material requirements, whether they are working with lower-melting-point copper alloys or ultra-high-temperature refractory metals and ceramics.
• Integrated Mold Tilting and Casting Assembly: A manually operated tilting mechanism is built directly into the vacuum chamber, enabling operators to pour the molten charge into a pre-positioned ingot mold. This ensures that the casting process takes place entirely under vacuum or protective gas, eliminating the risk of oxidation and ensuring the cast ingot retains its desired microstructural characteristics.
• Comprehensive Atmosphere Flexibility: The equipment is designed to operate under multiple atmospheric conditions, including high vacuum, vacuum with backfilled gases, and positive-pressure protective atmospheres up to 0.05 MPa. This allows researchers to tailor the gas environment using argon or nitrogen, preventing volatile element loss and suppressing slag formation.
• Interactive Process Simulation Interface: The control panel features a graphic simulation screen that represents the operational layout of the system in real time. Operators can view the status of vacuum valves, gas inlets, water flow, and induction power at a glance, reducing operational errors and ensuring safe, logical process sequencing.
• Non-Contact Infrared Temperature Tracking: A high-temperature infrared pyrometer is mounted to focus directly on the crucible surface, providing continuous, real-time temperature readings. This non-contact method avoids the degradation issues common with standard thermocouples at temperatures above 1600°C, ensuring accurate thermal profiling.
• Water-Cooled Stainless Steel Chamber: The vacuum chamber is constructed from heavy-gauge stainless steel with an integrated cooling jacket. Active water cooling keeps the external shell temperature below 35°C during high-temperature runs, protecting operators from accidental burns and maintaining a comfortable laboratory environment.
• Precise Real-Time Power Adjustment: The induction power supply features a manual control dial that allows for real-time power adjustment. This gives the operator fine-grained control over the heating rate and allows for precise thermal holding steps, which are necessary for degassing and refining sensitive alloy melts.
