Fireproof fiber layer for high-temperature furnace roller

Abstract

The invention provides a fireproof fiber layer for a high-temperature furnace roller. The fireproof fiber layer comprises the following components in parts by mass: 55-65 parts of silicate fibers, 13-20 parts of silica aerogel, 4-7 parts of aluminum phosphate gel, 3-5 parts of an acidic aqueous solution of ethyl orthosilicate, and 10-17 parts of an admixture. The fireproof fiber layer has excellent fire resistance and mechanical strength, is suitable in cost and can be used for directly machining the surface of the furnace roller, the fire resistance of the furnace roller is improved, and the service effect and time of the furnace roller are improved.

Description

technical field [0001] The invention belongs to the field of refractory materials, and in particular relates to a refractory fiber layer used for high-temperature furnace rolls. Background technique [0002] Furnace rollers are large-diameter hearth rollers used in continuous annealing production lines, and their quality is one of the main factors affecting the operating rate and product surface quality. , so that the surface is prone to defects, resulting in the decline of its refractory performance, which further leads to a significant reduction in its mechanical properties and a reduction in product quality. Therefore, it is particularly important to ensure the refractory performance of the furnace roll. Wrap a layer of refractory material. [0003] Therefore, developing a high-quality refractory material is an urgent problem for those skilled in the art. Contents of the invention [0004] In order to solve the above problems, the invention discloses a refractory fibe...
