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.
Claims11
An interconnectable refractory anchor for receiving moldable refractory material together creating a protective ceramic refractory lining minimizing erosion and increasing the useful life of the protective ceramic refractory lining in a vessel, the interconnectable refractory anchor comprising:
- a. a first tab comprising a first tab main body having a longitudinal axis and first tab spacer guide extending transversely to the longitudinal axis of the first tab main body;
- b. a first side integrally connected at a first obtuse angle to the first tab;
- c. a second tab comprising a second tab main body having a longitudinal axis and a second tab spacer guide extending transversely to the longitudinal axis of the second tab main body;
- d. a second side integrally connected at a second obtuse angle to the second tab;
- e. a bottom side integrally connected at a third obtuse angle with the first side and simultaneously integrally connected at a fourth obtuse angle with the second side, wherein the bottom side comprises a first bottom hole spaced apart from a second bottom hole;
- and
- f. at least one first punched lance formed centrally in the first side;
- and at least one second punched lance formed centrally in the second side, wherein the punched lances are adapted to contain moldable refractory material;
- and wherein the first tab of the interconnectable refractory anchor engages a second bottom hole of a second interconnectable refractory anchor and a second tab of a third interconnectable refractory anchor engages a first bottom hole of the second interconnectable refractory anchor.
An interconnected anchoring system for use in repair of protective ceramic refractory linings in high temperature severe duty vessels and for creating a protective ceramic refractory lining in high temperature severe duty vessels, the interconnected anchoring system comprising:
- a. a first interconnectable refractory anchor weldable to a vessel,
- b. a second interconnectable refractory anchor slidable into the first interconnectable refractory anchor;
- and
- c. a third interconnectable refractory anchor slidable into the first and second interconnectable refractory anchors forming the interconnected anchoring system with a plurality of closed geometric shaped spaces and generally U-shaped spaces adapted for receiving moldable refractory material, wherein the moldable refractory material is adapted to cure to a service temperature creating a protective ceramic refractory lining over the vessel and wherein each interconnectable refractory anchor comprises:
- (i) a first tab with a first tab spacer guide extending transversely to a longitudinal axis of the first tab main body;
- (ii) a first side integrally connected at a first obtuse angle to the first tab;
- (iii) a second tab comprising a second tab spacer guide extending transversely to a longitudinal axis of the second tab main body;
- (iv) a second side integrally connected at a second obtuse angle to the second tab;
- (v) a bottom side integrally connected at a third obtuse angle with the first side and simultaneously integrally connected at a fourth obtuse angle with the second side, wherein the bottom side comprises a first bottom hole spaced apart from a second bottom hole;
- and
- (vi) at least one first punched lance formed centrally in the first side;
- and at least one second punched lance formed centrally in the second side.
