Electric Rare Alloy Smelting Furnace Overview

The electric rare alloy smelting furnace is a multi-purpose high-temperature electric furnace developed for smelting and refining rare and refractory alloys, covering ferrotungsten, ferromolybdenum, ferrovanadium, tungsten-molybdenum alloys, titanium alloys and rare earth master alloys. With an ultra-high working temperature up to 2600°C and optional atmosphere control, the furnace meets the strict alloying and purity requirements of rare alloy production for aerospace, electronics, energy and special steel industries.

Core Features

• Ultra-High Temperature Capability: Arc heating combined with optimized furnace lining supports stable operation up to 2600°C, fully melting refractory metals such as tungsten (3422°C melting point) and molybdenum without dead zones.
• Flexible Atmosphere Control: Optional vacuum, argon or nitrogen protection atmosphere prevents oxidation of active elements in vanadium, titanium and rare earth alloys, guaranteeing high alloy purity.
• Precise Alloy Composition: PID temperature control with ±10°C accuracy and electromagnetic stirring keep the molten bath uniform, producing consistent ferrovanadium, ferromolybdenum and tungsten-molybdenum alloy grades.
• Multi-Purpose Design: One furnace handles smelting, alloying and refining of multiple rare alloy systems, with exchangeable crucibles and rapid heat-up for flexible small-batch production.
• Safe Operation: Hydraulic tilting pouring, anti-splash cover, water-cooled electrode holders and interlock alarm systems ensure stable and safe operation.
