Home Products Heat Treatment Industry / Graphitization Furnace Rack
A graphitization furnace rack is a structural component used in high-temperature furnaces designed for the graphitization process, which transforms carbon-based materials into graphite at extreme temperatures (typically 2000–3000°C). These racks are crucial for holding materials such as carbon electrodes, synthetic graphite, and other carbon-based products during heat treatment.
A graphitization furnace rack is a critical structural component in graphitization furnaces used for producing high-purity graphite materials. These furnaces operate at extremely high temperatures, typically ranging from 2,000°C to 3,000°C, to convert carbon-based materials into graphite through a process called graphitization.
The furnace rack serves multiple key roles, including:
Supporting Graphitization Loads – It holds the carbon materials, such as electrodes, carbon fibers, or graphite blocks, ensuring proper alignment during heat treatment.
Heat Resistance & Stability – Designed to withstand extreme temperatures while maintaining structural integrity.
Electrical Conductivity – Some racks are designed to conduct electricity for resistance heating in furnaces where the rack itself acts as part of the circuit.
Thermal Insulation & Uniformity – Helps in distributing heat evenly across the materials, improving the consistency of graphitization.
Since the furnace operates at high temperatures, racks are typically made from:
Graphite or Carbon-Carbon Composites – These materials can endure extreme heat and have excellent thermal stability.
High-Purity Refractory Metals (e.g., Molybdenum, Tungsten) – Used in specialized applications requiring additional strength and durability.
Types of Graphitization Furnace Racks
Fixed Racks – Used in batch furnaces where materials are loaded and unloaded manually or via a robotic system.
Modular or Adjustable Racks – Designed for flexibility to accommodate different material sizes.
Conductive Racks – Play a role in direct resistance heating, allowing the passage of electric current for uniform heat generation.
Graphitization furnace racks are widely used in industries such as:
Lithium-ion Battery Production (Graphite anode material).
Semiconductor Manufacturing (High-purity graphite parts).
Aerospace & Defense (Carbon-carbon composite components).
Metallurgical Industry (Graphite electrodes for steelmaking).
