UNIVERSAL FIREPROOF FASTENING STUD

摘要

The invention relates to the field of mechanical engineering, and specifically to fastening means, for example bolts, studs, screws and other rod-type fastening elements. The universal fireproof fastening stud is in composite form, wherein part of the stud is ceramic composed of high-strength fireproof phosphate concrete and is in the form of a cylinder with a hemispherical head, and the other part is metallic in the form of a threaded stud cast into same concrete in the manufacturing process and with a disc spring arranged thereon with a nut of the "wing nut" type for fastening the stud to a supporting casing of a furnace. The technical result is an increase in the strength of a universal fireproof fastening stud and of the connection of an internal surface of the lining of a furnace to an external casing.
