Embodiment 1

[0024] A kind of rapid repair refractory material, by mass percentage, the composition is as follows:

[0025]

[0026] During construction, the above-mentioned formula materials are formulated into products according to the production process, and each bag of material in the product packaging is poured into a forced mixer and mixed for two minutes. After mixing evenly, add water. The amount of water added is 2.8% of the total weight of the formula materials, and continue to stir From 3 minutes to 5 minutes, sample 1 was prepared by ramming method; according to the same method, the amount of water added was 5.8% of the total weight of the formula material, sample 2 was prepared by vibration casting method, and its performance index was tested.

Abstract

The invention discloses a rapid-repair refractory material and preparation and use methods thereof and belongs to the technical field of refractory materials. The refractory material comprises the following components in percentage by weight: 22-78% of brown fused alumina, 12-42% of SiC, 6-9% of alpha-Al2O3 micro powder, 1-2% of silicon dioxide micro powder, 1-4% of metallic silicon powder, 0-3% of clay, 3-5% of a phosphoric acid solution, 2-4% of magnesite clinker, 3-8% of magnesium-aluminum spinel and 4-6% of solid aluminum dihydrogen phosphate. The rapid-repair refractory material has the advantages of meeting requirements of high strength, good alkali resistance, wear resistance and thermal shock resistance and rapid hardening, and enriching material systems of the refractory materials.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a quick repair refractory material and its preparation and use method. Background technique [0002] Since the 1990s, my country has actively tried to use cement kilns to co-process waste. However, due to factors such as unclear waste characteristics, immature treatment processes and key technologies, and insufficient experience in enterprise operation and management, the industrial development is still at a low level. In the initial stage, the co-processing of solid waste in cement kilns is facing a bottleneck that is difficult to implement with good technology. This includes the problem of reduced service stability and reduced service life of refractory materials used in co-processing of cement kilns. Due to the gas generated during solid waste incineration (such as HCl, SO 2 , Cl 2 , CO and alkali metal gases, etc.) are highly corrosive to refractory...
