Fiber toughened refractory material

Abstract

The invention belongs to the technical field of refractory materials and discloses a fiber toughened refractory material. The material is mainly prepared from raw materials in parts by weight as follows: 40 parts of magnesium oxide, 85-95 parts of calcium oxide, 5-7 parts of toughening fiber, 1-3 parts of a granulation binder and 0.5-1.0 part of a forming binder. The refractory material adopts the reasonable raw material proportion, the refractory performance is higher, and the coat can be reduced properly; the fiber toughened refractory fiber has higher fracture toughness and better mechanical shock resistance.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a fiber-toughened refractory material. Background technique [0002] In the traditional sense, refractory materials refer to inorganic non-metallic materials with a refractoriness of not less than 1580 °C. And parts of the material, and can withstand the corresponding physical and chemical changes and mechanical action. [0003] Most refractory materials are made of natural ores (such as refractory clay, silica, magnesite, dolomite), and some industrial raw materials and synthetic raw materials (such as industrial alumina, silicon carbide, synthetic mullite, Synthetic spinel, etc.) are also increasing, so there are many types of refractory materials. According to the mineral composition, refractories can be divided into silica, aluminum silicate, magnesia, dolomite, olivine, spinel, carbonaceous, zirconium-containing refractories and special refractories; according...

Problems solved by technology

[0004] The poor mechanical toughness of inorganic non-metallic materials is a common problem in inorganic non-metallic materials and materials. As refractory materials that belong to inorganic non-metallic materials, their mechanical toughness is also poor. However, its poor mechanical toughness also affects its thermal shock resistance at high temperatures. Due to the large temperature difference between rapid cooling and rapid heating and use, refractory materials are prone to cracking and peeling under the action of thermal expansion and contraction. The situation that affects the integrity of refractory materials reduces the service life of refractory materials; at the same time, for those refractory products that need to be moved frequently, their poor mechanical toughness will greatly increase the damage rate of refractory products and affect their daily use.
