Vitrified Ceramic Jacket for Graphite Crucibles
The Delmer Vitrified Ceramic Jacket is a precision-engineered protective sleeve designed to extend the operational life of graphite crucibles used in induction melting furnaces. Manufactured from high-grade vitrified ceramic, it provides structural reinforcement, thermal insulation, and resistance to mechanical stress during repeated heating and cooling cycles.
Key Benefits
- Extended Crucible Life: Reduces wear and cracking on graphite crucibles, lowering replacement frequency and total cost of ownership.
- Thermal Stability: Withstands high-temperature induction melting environments without deformation or spalling.
- Structural Reinforcement: Absorbs mechanical shock and thermal expansion stress, protecting the crucible body during tilting and pouring operations.
- Chemical Resistance: Vitrified ceramic surface resists flux contamination and metal splash, maintaining a clean melting environment.
- Precision Fit: Available in matched sizes (2kg, 5kg, 10kg, 20kg) to fit standard Delmer graphite crucibles without modification.
Specifications
- Material: High-density vitrified ceramic
- Available Sizes: 2kg | 5kg | 10kg | 20kg (matched to crucible capacity)
- Finish: Glazed ceramic exterior for smooth, non-porous surface
- Compatible With: Delmer graphite crucibles used in iD Series and iD Pro induction melting furnaces
- Application: Gold, silver, platinum, copper, and other precious and non-ferrous metal melting
Applications
Ideal for jewellery manufacturers, precious metal refiners, casting houses, and industrial foundries operating induction melting furnaces. The ceramic jacket is a recommended consumable for any operation seeking to reduce crucible breakage, minimize downtime, and maintain consistent melt quality across production runs.
Ordering Information
Select the size that matches your graphite crucible capacity. For bulk orders or custom sizing requirements, contact Delmer Group directly for a quotation.
Related Furnaces and Consumables
Select the ceramic jacket only after confirming that its dimensions and design match the graphite crucible and intended furnace. Explore Delmer static and tilting induction melting furnaces for suitable batch-melting applications and Delmer gold and silver bar furnaces for bullion-production workflows. For continuous production of rods, strips or profiles, review Delmer continuous casting systems as a process option; this jacket is not a universal accessory for every system, and compatibility must be confirmed.
Compare the graphite crucible supplied with a vitrified ceramic jacket and the graphite crucible without jacket. Browse graphite, ceramic and metal-finishing consumables or contact Delmer with the crucible size and furnace model for confirmation.
