Pilot-Scale High-Temperature Molten Salt Electrolysis Furnace for Metal Refining and Smelting

Introduction

The ZYLAB Pilot-Scale High-Temperature Molten Salt Electrolysis Furnace is specifically designed for advanced metal processing, smelting, and purification applications. This furnace is widely used in the molten salt electrolysis of various metals, including tungsten (W), aluminum (Al), lithium (Li), lead (Pb), tin (Sn), cobalt (Co), nickel (Ni), and titanium (Ti). Among these, aluminum production is one of the most common and successful applications, as molten salt electrolysis remains one of the most effective methods for producing high-purity aluminum.

This pilot-scale system bridges the gap between laboratory research and industrial production. It provides a reliable solution for validating experimental results at a pre-production scale, offering a solid theoretical and practical foundation for future continuous production processes.

By using PLC automatic control and a user-friendly touchscreen interface, the furnace ensures precise temperature management, stable operation, and simplified process control. The high thermal efficiency, low energy consumption, and environmentally friendly design help reduce resource waste and environmental impact, while maintaining a cost-effective and highly efficient electrolysis process.

For laboratory users, we recommend our Lab Scale Molten Salt Electrolysis Furnace for Metal Refining and Smelting and Mini Molten Salt Furnace for Laboratory Electrochemistry and High-Temperature Research, which are better suited for experimental research and small-scale studies.
