Introduction

This vacuum atmosphere sintering furnace integrates a vacuum and gas control system, allowing pre-vacuuming of the furnace chamber followed by backfilling with high-purity gases such as nitrogen, argon, or nitrogen-hydrogen mixtures. After deoxidation and dehydration treatment, the system supports various heat treatment processes—including degreasing, sintering, and annealing—under a controlled atmosphere. For degreasing applications, an optional partial pressure system and oil cooling/collection unit are available.

Key Features of Vacuum Atmosphere Sintering Furnace

High-Performance Heating System

Equipped with a ceramic fiber insulation chamber and MoSi₂ heating elements, the furnace can reach temperatures up to 1600 °C.

Multi-Zone Temperature Control

Supports multiple independently controlled heating zones based on furnace length, ensuring excellent temperature uniformity throughout the working space.

Robust Vacuum System

Integrated two-stage rotary vane mechanical pump and Roots pump allow for fast evacuation. Ultimate vacuum: 7×10⁻¹ Pa.

Advanced Control Interface

HD touchscreen HMI with our proprietary control software.

PLC-based automation ensures precise process execution and reliable operation.

Efficient Gas Flow Design

The gas system features a dedicated circuit where high-purity N₂ (or other gases) enters the chamber post-deoxidation and dehydration, circulates effectively, and exits through a dedicated exhaust, maintaining a stable protective atmosphere.

Trolley-Type Bottom Access

Furnace base features an electric-driven trolley design for easy loading/unloading outside the chamber, simplifying maintenance and operation.

Optional Components

Silicon nitride (Si₃N₄) loading box

Silicon nitride (Si₃N₄) protection board
