  • Patent number: 4753053
    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.
