Abstract

The invention discloses a high-temperature-resistant fiber sheet, a preparation method and a fiber roller press-fitting method. The high-temperature-resistant fiber sheet is prepared from the following raw materials: 45-60% of ceramic fibers, 5-15% of mineral fibers, 10 to 20% of a clay mineral and 10-20% of silicon dioxide, with the balance being water. The preparation method comprises the following steps: burdening, stirring, forming, stamping and drying. The fiber roller press-fitting method comprises the steps of preparation, hoisting, sheet taking and press-fitting. The fiber sheet is convenient to manufacture, good in high-temperature resistance, not prone to sintering at high temperature, proper in surface hardness and not prone to causing scratches to strip steel at high temperature, the service life of a furnace roller is prolonged, the surface quality of the strip steel is greatly improved, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of materials, in particular to a high-temperature-resistant fiber sheet, a preparation method and a fiber roll pressing method. Background technique [0002] Stainless steel cold-rolled continuous annealing furnace, the working temperature is generally as high as about 1150 ℃, the cold-rolled stainless steel strip is continuously annealed in the furnace, and the operation of the steel strip in the furnace is supported by high-temperature resistant non-metallic rollers. Non-metallic rollers are sintered at high temperature, have high surface hardness, are easy to scratch the strip steel at high temperature, have poor high temperature resistance, have no elasticity at high temperature, and have large shrinkage and cracks during use, which can easily cause surface defects on the strip steel, thereby The product is reduced to inferior or judged as scrap steel, which directly affects the yield of the product.
