Composite refractory articles

Abstract

Abstract THE INVENTION PROVIDES A POROUS, FIBROUS SUBSTRATE AND COMPOSITE REFRACTORY ARTICLES IN WHICH THE SUBSTRATE SERVES AS A RE-ENFORCEMTNT AGAINST THERMAL AND SHOCK STRESSES. THE SUBSTRATE IS MADE FROM REFRACTORY INORGANIC FIBERS, THE SUBSTRATE SERVING AS A BASE FOR THE DEPOSITION OF A SUITABLE LAYER OF REFRACTORY MATERIAL WHICH MAY BE APPLIED BY ANY OF SEVERAL KNOWN METHODS. THE SUBSTRATE AND ADHERING REFRACTORY LAYER MAY THEN BE DRIED TOGETHER TO PRODUCE A COMOSITE REFRACTORY ARTICLE OR THE DRIED ARTICLE MAY BE FIRED TO GIVE A COMPOSITE ARTICLE WITH A DENSIFIED REFRACTORY LAYER. IN EITHER CAUSE THE SUBSTRATE REMAINS FIRMLY ATTACHED TO THE REFRACTORY LAYER AND FUNCTIONS AS A MECHANICAL RE-ENFORCING AND THERMAL INSULATING SUBSTRATE FOR THE RESULTING COMOSITE REFRACTORY LAYER AND FUNCTIONS AS A MEMAY BE FURTHER STRENGTHENED BY PROVIDING A LAYER OF REENFORCING METAL OVER THE OUTER SURFACE OF THE COMPOSITE ARTICLE. THE METAL LAYER MAY BE A CASTING OR A SHEET METAL CASING SHAPED TO ENCLOSE AND PROVIDE SUPPORT FOR THE ARTICLE AT ITS POINT OF USE.
