Refractory Anchors Products supplier manufacturer and exporter in India
A refractory anchor is an essential component used to secure refractory products inside high-temperature industrial equipment such as furnaces, kilns, boilers, and reactors. These industrial refractory anchors are designed to withstand extreme heat, chemical exposure, and mechanical stress while maintaining the stability of the refractory lining. Typically, the anchors products are formed by die-stamping, wire shaping, or welding, and then threaded or bent into specific designs to meet different application requirements.
Anchors are most commonly installed on vertical walls or ceilings of the refractory structure because these areas carry the heaviest load, and the materials must be strong enough to prevent deformation or failure under high stress. Depending on the application, the cross-section of a refractory anchor may be circular or rectangular—circular anchors are suitable for thinner refractory linings, while rectangular anchors provide greater load support for thicker linings.
Stainless steel refractory anchors, including grades 304, 310, and 316, are widely preferred due to their excellent combination of mechanical strength, corrosion resistance, and cost-effectiveness. High-performance nickel-based alloys such as Inconel, Monel, and Hastelloy are also used in applications requiring extreme heat resistance. Anchor products are available in multiple shapes and sizes, including flat, wire, and Y-shaped designs, each offering specific advantages for load distribution and thermal performance.
Industries such as steel, cement, petrochemical, ceramic, power, and thermal sectors rely on these refractory anchors to ensure long-lasting performance of their refractory linings. The choice of anchor material, shape, and quantity significantly impacts the service life and safety of industrial equipment. Amardeep Steel Centre is a trusted refractory anchors manufacturer, supplier, and exporter, offering a wide range of shapes, sizes, and alloy options to meet diverse industrial requirements.
