Stainless Steel Refractory Anchors

Up to 40% of refractory-lining failures are thought to be the result of a fault with the anchor system's design or incorrect installation. This is a significant amount. Anchor design becomes one of the most critical components in developing a durable refractory lining that is appropriately supported when building a refractory lining for an industrial application. Because the points of the anchors are closest to the hot face, they endure the highest temperatures and so constitute a significant factor. Anchors serve a variety of purposes. To protect the refractory from falling in, they secure it to the wall. They help reduce wall buckling caused by high temperatures' internal thermal pressures. Anchors can also assist sustain the load of the refractory weight to a lesser extent.

To produce a monolithic refractory lining that is correctly supported and maximizes service life, here are three crucial metallic anchor suggestions to know.

Anchor size for a refractory lining is determined by the thickness of the refractory and the number of components. Some designers choose for a 75-85 percent anchor height through the main thick castable or gunned lining. For thicker lining designs bigger than 6-7 inches, other industry rules of thumb state that the anchor tip should be no more than 2 inches from the hot face of the refractory.

Knowing the temperature gradient through the refractory lining, from the hot face to the cold face, is helpful in selecting the right anchor size to avoid exceeding the alloy's temperature limit. Many industry professionals may utilize a heat loss calculator/estimator to assist determine the right temperatures at various places in the refractory lining.

Anchor spacing should be determined by the unique characteristics of each project, such as the mechanical qualities of the anchor and the temperature response of the refractory lining. These attributes will be used in mathematical models by refractory engineers to assist them to build the best anchor spacing pattern and strategy.

Incorporate these metallic anchor points to minimize vessel lining failures, extend service life, and maximize refractory performance. These suggestions might help you develop and optimize an anchoring system that will meet the stringent requirements of refractory linings.
