1. Overview of Equipment and Application Fields

The High Vacuum Induction Furnace H6 is a high-performance, customizable smelting system designed for experimental and small-batch production applications. Specifically engineered to address critical issues in traditional smelting processes—including oxidation inclusions, compositional segregation, and insufficient density—this equipment utilizes two core technologies: high-vacuum induction melting combined with physical mechanical stirring and vacuum secondary feeding. These integrated methods ensure the ultimate purity, uniformity, and density of molten metal. It is particularly suitable for producing high-performance materials such as precious metals (gold, silver), non-ferrous metals (copper), ferrous metals (iron), and various specialty alloys.

The H6 system not only inherits the traditional advantages of induction melting—rapid temperature rise and high thermal efficiency—but also achieves a qualitative leap in process performance through innovative functional integration. Its physical stirring function effectively prevents stratification of metal elements with different densities during melting, ensuring microscopic homogeneity of alloy composition. The vacuum secondary feeding system allows the addition of easily oxidizable elements without compromising the vacuum environment, completely eliminating oxidation-induced burnout. Equipped with an advanced PLC control system, the device features intuitive operation and robust 24-hour continuous operation capability, significantly enhancing research efficiency and small-batch production capacity. Its multiple safety protection mechanisms provide solid safeguards for both laboratory and production environments.
