Refractory Anchors

Industrial furnaces, kilns, reactors, ovens, and vessels utilize extreme temperatures to cause chemical reactions or physical changes in workpieces. In most cases, these extraordinary conditions would immediately destroy the application’s shell. For this reason, materials that are resistant to heat, pressure, and chemical degradation are used as protective barriers. Commonly called refractories, refractory materials, or refractory linings, they provide a range of benefits.

To optimize refractory lining performance, anchoring systems are used to secure refractory castables, board, ram plastics, fiber insulation, and ceramic fiber modules to the furnace or kiln shells. These devices are manufactured from heat-resistant stainless steel and nickel alloys and serve several purposes.

• Hold the refractory to the wall to keep it from falling in
• Prevent wall buckling due to the internal thermal stresses created by high temperatures
• Help support the load of the refractory weight

When you need high-quality refractory anchors, Delta Stud Weld is here to help. As a leading refractory anchor supplier, we can hastily deliver these fastening devices in various sizes and configurations.

Refractory anchoring hardware must be manufactured from high-quality materials because, being closest to the hot face, they experience the highest temperatures. Delta Stud Weld manufactures all high-temperature refractory hardware using materials sourced from trustworthy domestic mills. Examples include stainless steel refractory anchors or nickel alloy refractory accessories. Here are the materials we typically use:
