What are the Applications of Stainless Steel Refractory Anchors? These metal pieces are used to secure refractory to the wall, preventing internal thermal stresses from buckling the wall. Metal anchors also help support the weight of the refractory. They are designed to maximize refractory service life. These metal pieces are available in a variety of sizes and shapes.
The definition of stainless steel refractory anchors
These anchors are manufactured for cement, steel, and petrochemical industries to hold refractory linings. They are available in different qualities and sizes. Stainless steel anchors contain chromium and nickel.
Typical grades offer corrosion resistance and ductility at high temperatures. Some of these anchors are even made of Inconel 601, which offers excellent resistance to oxidation, carburization, and sulfidation.
These refractory anchors are designed to resist corrosion from corrosive acids and oxidants. They also have excellent formability and are durable, perfect for industrial applications. Stainless steel refractory anchors are available in 18/8 stainless steel, carbon steel, and alloy steel. These anchors are available in different sizes and thicknesses. Stainless steel 304H Refractory Anchors are available in different depths to fit various refractory materials.
The thickness of the main lining is approximately 9 inches. The side wall is made of either 60 alumina low-cement castable, which is lightweight, or a 2300degF insulating castable. The refractory anchors should be at least two inches wide and four inches long to be effective. The anchors should be selected according to the refractory material thickness and the desired temperature gradient.
Features Of Stainless Steel Refractory Anchors
A refractory anchor is a structural component of a refractory vessel, such as a boiler, that consists of a metal crossbar and a refractory lining. These components are generally stamped from sheet metal, with the base being typically frustoconical.
Steel Refractory Anchors The refractory crossbar comprises an intermediate portion, or S-section, and extending arms. The arms of the S-section are cut at an angle of approximately 95 to 150 degrees. At least one of these arms is bent to provide an arcuate portion for receiving the refractory lining.
When installing refractory anchors, it is necessary to use a type of insulating material to prevent the anchor from deteriorating over time. Twin pin anchors are easy to install and can be made using manual welding. After fastening the anchor, the strip must be bent outwards, which keeps the refractory material in place. To increase the insulating ability of the stainless steel refractory anchor, the insulating material can be added to the end of the pin.
Another type of refractory anchor is the S-bar refractory anchor. This anchor is similar to the S-shaped anchors in FIGS. 1 and 3, but is taller. It is made of a 16 gauge stainless steel strip and has arms that are bent in one-half-inch circles. They can be spaced at intervals of one-half inch, with spacing determined by the length and diameter of each anchor.
