Refractory anchors are metal elements designed to secure and hold refractory linings in place within furnaces, boilers, incinerators, and other industrial equipment. They prevent the refractory material from shifting or detaching due to temperature changes, thermal expansion, and vibrations. Made typically from stainless steel or special alloys that resist corrosion and heat, these anchors are designed according to the specific application or type of refractory lining they need to support (bricks, concrete, ceramic fiber, etc.). They are crucial to ensuring the durability and integrity of the refractory lining under extreme conditions.
