Abstract: An interconnectable refractory anchor for receiving moldable refractory material together and creating a protective ceramic refractory lining minimizing erosion and increasing the useful life of refractory linings in reactors and vessels. The interconnected anchoring system comprises a plurality of interconnectable refractory anchors for use in a high temperature severe duty environment. The steps of the method comprise interconnecting a plurality of refractory anchors, fastening the interconnected anchoring system to a vessel, fitting a moldable refractory material into the spaces, and curing the moldable refractory material to service temperature creating a protective ceramic refractory lining for the vessel.

Abstract: A system for testing abrasion resistance of a test specimen made of refractory material, wherein the system includes an insulated furnace with a first chamber having a refractory lining, a second chamber disposed within the first chamber, a tube for flowing pressurized air into the second chamber, a conduit for flowing heated air from a burner operating on a fuel to the second chamber, for mixing with the pressurized air, and an air gun for mixing an abrading material into the pressurized air prior to introduction to the test specimen.

Abstract: A support anchor is provided for anchoring a castable or plastic refractory material to a processing vessel wall. The support anchor of the present invention includes a flat center member portion and portions integrally formed with and extending transversely with respect to each end of the center member. Attachment members are formed at an inner edge of the support body so that the support body is mounted at a spaced position from the vessel wall. Plural openings are formed in the support body to allow flow of refractory material during installation to aid in at least partial bonding of the installed refractory and the support anchor. Anchoring members are mounted adjacent the openings in the support body to provide anchoring support submerged within the installed refractory material.
