InterLok™ Segmented Crucible Lining Systems
Large induction furnace linings are subjected to repeated heating and cooling cycles that create significant thermal expansion. The InterLok™ Segmented Crucible System addresses these stresses through a precision-engineered tongue-and-groove ceramic tile design. Rather than relying on a traditional monolithic lining, the modular construction allows the lining system to maintain dimensional stability while providing a durable, repeatable solution for vacuum and air induction melting furnaces. Manufactured to precise tolerances using Blasch's ceramic process, each system is designed for consistent fit, simplified installation, and reliable performance throughout its service life.
Custom Engineered for Your System
We offer comprehensive customization of the InterLok system to meet the unique requirements of your operation. Our solutions include pre-cast integrated spouts and spout extensions, ensuring seamless flow control and durability. We also provide bottom and side through holes for bottom pour systems, designed to enhance efficiency and precision in metal casting applications.
Whatever your specific needs, Blasch’s engineered solutions deliver reliability, consistency, and superior functionality.
Designed to Improve Your Process
The InterLok lining system has been engineered to offer several advantages to users:
• Improved metal quality with fewer impurities
• Reduced spalling and erosion, providing longer crucible life
• More predictable performance due to consistent crucible characteristics
• Simple modular construction of coded tiles for quick assembly
• Dramatically lower labor costs and time for installation and disassembly

Standard Sizes with Custom Capabilities
The InterLok™ Segmented Crucible System is engineered to accommodate a wide range of induction furnace applications, with standard configurations available for furnaces from 650 to 15,000 pounds. Each system is designed with flexibility in mind, allowing key design elements such as side brick height, course count, and integrated components to be customized to meet specific furnace dimensions, operating conditions, and process requirements.
This adaptable approach enables InterLok™ to provide a precise fit for both standard installations and specialized melting applications. By combining a proven segmented refractory design with application-specific engineering, the system delivers a reliable and optimized crucible solution tailored to the unique demands of each operation.
