Abstract: Metal refractory anchors impregnated with special corrosion resistant material are provided to minimize erosion and corrosion as well as to increase the useful life of refractory linings in reactors, transfer lines, regenerators, and other vessels. In one embodiment, the refractory anchor has an S-shaped crossbar with reverse bent opposite ends. In another embodiment, the refractory anchor has a C-shaped crossbar with symmetrical arcuate ends.

Abstract: Specially configured refractory anchors are provided to minimize erosion and increase the useful life of refractory linings in reactors and other vessels. The refractory anchors have a frustroconical base and an overhead crossbar with an intermediate portion and opposite ends. At least one of the opposite ends has an arcuate portion to provide a curved baffle to arcuately deflect and block gases flowing along the refractory lining adjacent to the refractory anchors. Desirably, the crossbar provides an erosion resistant barrier to help protect the structural integrity of the refractory linings. The base extends downwardly from the crossbar and reinforces the refractory lining. The flared sides of the base diverge towards the opposite ends of the crossbar at obtuse angles of inclination to provide pockets for receiving and holding the refractory lining. In one embodient, the refractory anchor has an S-shaped crossbar with reverse bent opposite ends.

Abstract: A metal refractory anchor adapted for installation by welding to a metal surface together with a number of other like anchors to provide anchorage protection from erosion for a monolithic refractory applied to the surface, said anchor being formed from a metal strip having its width substantially equal to the thickness of the refractory to be applied to said surface and its length several times its width. The anchor has cut away portions at each end whereby there is provided at each end an extending arm, the extending arms together with the intermediate portion of said anchor providing an erosion resistant barrier for the protection of the refractory and the cut away portions adjacent said arms providing room for said refractory to be deposited between said arms and said surface.
