Abstract

Refractory anchoring devices include a main body and a mounting feature for mounting to a thermal vessel. The main body has the shape of two end-to-end Y's forming a central segment, branch segments extending from ends of the central segment, and extension segments extending from the branch segments, to collectively form four unenclosed cell openings that are semi-hexagonally shaped. Some embodiments include reinforcement segments extending into respective cell openings, voids extending through respective adjacent branch and extension segments, an underbody gap under the central segment, a single stud-welding stud for the mounting feature, and/or a collar-and-stud connection between the anchor main body and a stud-welding stud of the mounting feature. Refractory anchoring systems and methods include an array of the refractory anchoring devices arranged and mounted so that the unenclosed semi-hexagonal cell openings of adjacent anchoring devices cooperatively form substantially hexagonal cells.
