Abstract

The invention belongs to the technical field of spraying materials, and particularly relates to a high-strength heat- insulation fiber composite spraying material capable of quickly repairing heat damaged parts, prolonging service life and saving cost and a preparation method thereof. The high-strength heat- insulation fiber composite spraying material comprises the following components in percentage by weight: 50-54% of a mullite light material, 23-27% of spherical fiber wool, 4-6% of Guangxi white mud, 1.5-3% of guar gum, 6-9% of aluminum dihydrogen phosphate liquid, 4-6% of pure calcium aluminate 70 cement and 4-6% of silica micropowder. The invention aims to provide the high-strength heat- insulation fiber composite spraying material which can effectively solve the repair of heat damaged parts, prolong the service life and save cost and a preparation method thereof with simple process and low cost.

Description

technical field [0001] The invention belongs to the technical field of injection materials, and in particular relates to a high-strength heat-insulating fiber composite injection material capable of quickly repairing heat-damaged parts of a blast furnace or a hot blast stove and a preparation method thereof. Background technique [0002] The spray material is a bulk refractory material constructed by spraying, which is composed of refractory aggregate and powder with a certain particle size, binder and admixture. The jet power is usually compressed air. The main material is selected according to the maximum temperature that may be reached in the kiln, the range of temperature fluctuations, and the nature of the slag. The gunning material also needs to consider the material of the lining itself. The injection material is mainly used to form an integral inner guard and repair other furnace linings. The blast furnace or hot blast stove is partially damaged during use, and th...
