Abstract

The invention relates to a high-strength castable for a continuous caster tundish, which is prepared from the following components in parts by weight: 20-30 parts of magnesite, 10-20 parts of dolomite, 10-20 parts of zircon, 10-20 parts of graphite, 5-10 parts of phenol formaldehyde resin, 10-20 parts of zirconium oxide fiber and 5-10 parts of yttrium oxide. The magnesite, dolomite, zircon and graphite are mixed to obtain 45-50 parts by weight of particles and 50-55 parts by weight of fine powder; and the zirconium oxide fiber, yttrium oxide and phenol formaldehyde resin are used as additives. The particle size of the particles is 1.2-1.8mm, and the particle size of the fine powder is 0.3-0.8mm.

Description

Technical field [0001] The invention belongs to the technical field of refractory materials, and particularly relates to a high-strength castable for a continuous casting machine tundish. Background technique [0002] Compared with qualitative refractory products, unshaped refractory materials represented by refractory castables have the advantages of short process flow, low production energy consumption and cost, convenient use, wide application range, integrity and good use effect, and so on. The interior has been developed rapidly, and its proportion in the entire refractory material is getting higher and higher. In some countries with advanced refractory technology, the output of unshaped refractories has approached or even exceeded the output of shaped products. For example, the current output of monolithic refractories in Japan accounts for about 60% of the total refractories; in the United States, it is about 50%; in Britain, Germany, France and other countries, it is 40%...
