Electric Degreasing Furnaces up to 1750°C

This Electric Degreasing Furnace (also known as a thermal debinding and sintering furnace) is an essential thermal processing solution designed for precise binder removal, sintering, and high-temperature heat treatment. Capable of reaching maximum operating temperatures up to 1750°C, these furnaces utilize electric heating elements and specialized gas convection systems to provide clean, accurate, and repeatable thermal cycles necessary for modern advanced ceramics, powder metallurgy, and additive manufacturing.

Key Features & Technical Advantages

1. High-Temperature Performance & Superior Uniformity

   • Up to 1750°C Max Temperature: Designed to handle both low-temperature debinding and extreme high-temperature sintering in a single process cycle.

   • Four-Sided Heating: Multi-zone electric heating ensures tight temperature uniformity throughout the furnace chamber.

   • Multi-Layer Refractory Insulation: Utilizes lightweight hollow-sphere alumina and interlocking hearth structures to minimize thermal stress, reduce heat loss, and extend equipment lifespan.

2. Efficient Debinding & Thermal Management

   • Integrated Air Preheating & Filtration: Pre-heats intake gas up to 400°C and employs integrated gas filters to accelerate binder breakdown and catalytic debinding.

   • Convection-Assisted Processing: Variable-frequency airflow systems optimize heat transfer, reducing debinding times by 30%–50% while lowering energy consumption by up to 25%.

   • Clean Exhaust Architecture: Top-chimney gas routing lined with erosion-resistant ceramic fiber ensures efficient vapor removal, preventing slagging, carbon residues, cracking, or pore defects.

3. Smart Automation & Safety Protocols

• Programmable PLC Control: Intuitive touch-screen interface supports up to 30 programmable process curves for precise multi-stage debinding and sintering profiles.

• Automated Motion Control: Space-saving lift-type or bogie-hearth design with precision guided linear motion and mechanical anti-drop locks for safe, convenient loading and unloading (up to 50% enhanced hearth load capacity).

• Comprehensive Safety Alarms: Dual protection with over-temperature cutoff, thermocouple failure detection, and automatic emergency shutdown systems.
