Batch Type Vacuum Resistance Furnace for Ceramic Valve & Graphite Sintering
Batch Type Vacuum Resistance Furnace for Ceramic Valve & Graphite Sintering
Description:
- Available in octagon/rectangle structures, this 2200℃ resistance furnace (vacuum) uses resistance heating + sealed chamber to maintain high-temp stability. It supports 380V 3-phase power & thyristor control, with optional cooling tower.
- Designed for industrial durability, its smart temp control regulates heating rates to ensure uniform workpiece heating; 1-to-1 cabinet-furnace setups suit medium-scale production.
- User-friendly operation + safety safeguards (over-temp alert) make it suitable for lab and manufacturing scenarios.
Application:
- Ceramic Components: Sintering of ceramic valves, boron carbide plates, and zirconia.
- Carbon Materials: Dewax/degrease of PI film, heat treatment of graphite and radiation-proof material.
- Alloys: Processing of tungsten carbide, rhenium material, and hard alloy parts.
