Refractory anchor system
A Y-shaped refractory anchor, a plurality of Y-shaped refractory anchors, and a method of installing a plurality of Y-shaped refractory anchors in a hexagonal pattern is disclosed. The Y-shaped refractory anchor comprises a singular folded metal plate comprising a stem that comprises at least one triangular section to be welded to a backing surface and a folded stem base and a branch section comprising two branches, wherein the singular metal plate is folded together at the stem base, such that the stem of the Y-shaped anchor is twice as thick as the two individual branches.
1. A system of refractory anchors comprising: a plurality of Y-shaped anchors, wherein each Y-shaped anchor of the plurality of Y-shaped anchors comprises a singular rectangular folded metal plate comprising a stem to be welded to a backing surface along a flat back edge of the stem and a branch section comprising two individual branches, wherein the two individual branches create an obtuse angle and wherein the two individual branches have a flat back edge, wherein the singular metal plate is folded together at a stem base, such that the stem of the Y-shaped anchor is twice as thick as the two individual branches, wherein the stem of the Y-shaped anchor has at least one tapered triangular section located on the back edge of the folded stem to be welded to the backing surface, wherein the at least one tapered triangular section is designed to create a gap in between the back flat edge of the two individual branches and the backing surface upon welding the Y-shaped anchor to the backing surface, wherein the plurality of Y-shaped anchors are arranged to make a hexagonal-shaped pattern between the plurality of Y-shaped anchors on the backing surface, and wherein none of the plurality of Y-shaped anchors touch another of the plurality of Y-shaped anchors.
2. The system of claim 1 , wherein the two individual branches of each Y-shaped anchor comprise one void and one tab each.
3. The system of claim 1 , wherein the stem of the Y-shaped anchors has two tapered triangular sections to be welded to the backing surface.
4. The system of claim 1 , wherein the two individual branches are each one inch in length.
5. The system of claim 1 , wherein the stem is 0.9 inch in length.
6. A process of applying a plurality of Y-shaped anchors to a backing surface comprising: bringing a Y-shaped anchor of the plurality of Y-shaped anchors, wherein each Y-shaped anchor of the plurality of Y-shaped anchors comprises a singular rectangular folded metal plate comprising a stem to be welded to a backing surface along a flat back edge of the stem and a branch section comprising two individual branches, wherein the two individual branches create an obtuse angle and wherein the two individual branches have a flat back edge, wherein the singular metal plate is folded together at a stem base, such that the stem of the Y-shaped anchor is twice as thick as the two individual branches, wherein the stem of the Y-shaped anchor has at least one tapered triangular section located on the back edge of the folded stem, to be welded in contact with a backing surface wherein the at least one tapered triangular section is designed to create a gap in between the back flat edge of the two individual branches and the backing surface upon welding the Y-shaped anchor to the backing surface; stud welding the at least one triangular section to the backing surface; and repeating the bringing in contact and stud welding steps so that the plurality of Y-shaped anchors are arranged to make a hexagonal-shaped pattern between the plurality of Y-shaped anchors on the backing surface, and wherein none of the plurality of Y-shaped anchors touch another of the plurality Y-shaped anchors.
7. The process of claim 6 , wherein during the welding process, the Y-shaped anchor is held by a stud gun.
8. The process of claim 6 , wherein the triangular section includes a flattened edge that is pressed into the backing plate, the stud gun releases an electric charge that melts a part of the triangular section forming the weld joint between the anchor and the backing surface.
9. The process of claim 6 , wherein the plurality of installed Y-shaped anchors do not touch each other on the backing surface.
10. The process of claim 6 , wherein a disposable ceramic ferrule is used in the stud welding step.
11. The process of claim 6 , further comprising applying a refractory material to the plurality of Y-shaped anchors that is about one inch thick.
12. The process of claim 6 , wherein the backing surface is the interior of a fluid catalytic cracking unit.
