High-temperature refractory material and manufacturing process method

Abstract

The invention relates to the technical field of high-temperature refractory materials, and discloses a high-temperature refractory material and a manufacturing process method. The refractory brick comprises the following raw materials in parts by weight: 10-25 parts of a silicon oxide material, 10-15 parts of quartz sand, 5-6 parts of magnesium carbonate, 15-20 parts of corundum, 0.3-1.2 parts ofa rare earth-containing raw material, 7-8 parts of chromium dioxide, 0.7-1.2 parts of methylcellulose, 10-20 parts of mullite, 30-40 parts of dolomite, 0.5-0.7 part of sodium silicate, 20-30 parts ofa carbonic acid solution, 0.4-0.7 part of an expanding agent and 5-15 parts of a binder. According to the high-temperature refractory material, the silicon oxide material is added, and the bonding strength of the high-temperature refractory material is greatly improved, so that the high-temperature refractory material is prevented from caking and sagging, collapsing and sinking in the curing period, and meanwhile, the high wear resistance and corrosion resistance of the material can be enhanced, by adding corundum and dolomite raw materials, the strength and anti-pressure ability of the material body is increased, the body toughness degree of the high-temperature refractory material is improved by adding methyl cellulose, the production is simple, the raw material cost is low, and the quality effect is good.

Description

technical field [0001] The invention relates to the technical field of high-temperature refractory materials, specifically one. A high-temperature refractory material and a manufacturing process thereof. Background technique [0002] There are many kinds of refractory materials, which are usually divided into ordinary refractory materials, advanced refractory materials and special refractory materials according to their refractoriness, and acid refractory materials, neutral refractory materials and basic refractory materials according to their chemical properties. In addition, there are refractory materials for special occasions. At present, refractory materials generally refer to inorganic non-metallic materials used in the lining of production equipment such as metallurgy, petrochemical, cement, and ceramics. [0003] At present, with the wide application of refractory materials in various industries and the increasing demand, the existing production process is relatively...
