Refractory Anchors

Refractory anchors are usually used in high-temperature environments, such as furnaces, kilns, reactors, and other industrial equipment. We normally installed refractory anchors on the kiln shell or being the part of the steel structure to support the lining of kilns or furnaces.

Refractory anchors are small. However, it plays an important role in anchoring and connecting for furnaces, kilns and other industrial equipment. They are an essential part of modern refractory lining systems and are a key technical to enhance the life of equipment.

1. Support and Stabilization: Anchors help secure the refractory material in place, preventing it from sagging or collapsing due to gravity, thermal expansion, or mechanical stress.
2. Prevent Cracking: They help prevent collapse caused by ceramic bonding during heating and also promote uniform material shrinkage, thereby avoiding the formation of large and concentrated cracks in the lining.
3. Expansion Management: Refractory Anchors are designed to manage the thermal expansion and contraction of the refractory material, allowing it to expand uniformly without cracking or damaging the structure.

Refractory anchors come in various types, designed to secure different kinds of refractory linings under various conditions. Here are the main types of refractory anchors:

1. Y-Anchors

• Shape: Resemble the shape of the letter "Y."
• Use: Commonly used for lightweight refractories, insulating castables, or lining with low thickness.
• Characteristics: Provide good support and help in reducing stress concentration in the lining.

2. V-Anchors

• Shape: Resemble the letter "V."
• Use: Suitable for denser refractory linings and those subject to greater thermal expansion.
• Characteristics: Offer increased support and strength for thicker linings and help accommodate expansion.

3. U-Anchors

• Shape: Shaped like the letter "U."
• Use: Often used in ceramic fiber linings or monolithic linings to provide mechanical anchoring.
• Characteristics: Provide strong support and secure thicker lining materials to the metal casing.

4. Corrugated Anchors

• Shape: Have corrugated or wavy patterns.
• Use: Used in castable or gunned refractories to improve the bonding between the refractory material and the metal structure.
• Characteristics: Enhance grip and resistance to slipping, providing improved mechanical interlock.

5. Pin Anchors

• Shape: Simple, straight pins.
• Use: Commonly used for ceramic fiber or blanket insulation, holding the material against the metal casing.
• Characteristics: Easy to install and suitable for lightweight, flexible refractory materials.

6. Ceramic Anchors

• Material: Made from ceramic instead of metal.
• Use: Used in applications where metal anchors might oxidize, melt, or suffer corrosion at extremely high temperatures.
• Characteristics: Highly resistant to high temperatures and chemical attacks, ideal for environments above the melting point of metal anchors.

7. Threaded Anchors

• Shape: Feature a threaded end that can be fastened securely.
• Use: Used for attaching precast refractory shapes or for installations requiring tight fastening.
• Characteristics: Provide strong mechanical bonding, can be adjusted or replaced if needed.

8. Custom-Designed Anchors

• Shape and Design: Tailored to specific applications, shapes, and sizes.
• Use: Used in unique or challenging installations where standard anchors do not provide adequate support.
• Characteristics: Designed to meet specific engineering requirements, often customized for high-performance applications.

9. Hex Mesh Anchors

• Shape: Constructed in a hexagonal mesh pattern.
• Use: Used for thin or abrasion-resistant linings to provide added surface area and mechanical interlocking.
• Characteristics: Increase the bonding surface area and help distribute stress more evenly across the lining.

10. Cast-In Anchors

• Use: Integrated directly into cast refractory components during manufacturing.
• Characteristics: Provide secure attachment without requiring separate installation, offering a high-strength bond between the refractory and structure.

Each type of refractory anchor is designed to meet specific needs, such as temperature resistance, mechanical stress handling, or chemical corrosion resistance, making them versatile for various high-temperature industrial applications.

Refractory anchors are typically made from heat-resistant alloys, such as heat-resistant steel(1Cr18Ni9Ti) SUS321，304 Stainless Steel，310 Stainless Steel，316 Stainless Steel，Inconel，Carbon steel to endure the harsh conditions within high-temperature environments. Overall, refractory anchors are a critical component in ensuring the durability and longevity of refractory linings in industrial applications.
