Embodiment 1

[0019] Weigh 6.5 kg of special-grade 85 bauxite particles with a particle diameter of 2 mm, 1 kg of special-grade 85 bauxite fine powder with a particle diameter of 0.05 mm, and 0.5 kg of solid phosphoric acid. During construction, add 0.6kg of water and stir evenly. After the stirring is completed, vibrate the construction. After the vibration construction is completed, sinter according to the standard heating curve.

Embodiment 2

[0021] Weigh 7 kg of special-grade 85 bauxite particles with a particle diameter of 4 mm, 1.5 kg of special-grade 85 bauxite fine powder with a particle diameter of 0.05 mm, and 0.6 kg of solid phosphoric acid. During construction, add 0.6kg of water and stir evenly. After the stirring is completed, vibrate the construction. After the vibration construction is completed, sinter according to the standard heating curve.

Embodiment 3

[0023] Weigh 7.5 kg of special-grade 85 bauxite particles with a particle diameter of 6 mm, 2 kg of special-grade 85 bauxite fine powder with a particle diameter of 0.05 mm, and 0.7 kg of solid phosphoric acid. During construction, add 0.6kg of water and stir evenly. After the stirring is completed, vibrate the construction. After the vibration construction is completed, sinter according to the standard heating curve.

[0024] The above-mentioned embodiment retains all the advantages and characteristics of phosphoric acid combined with quick-drying materials by adding a certain proportion of solid phosphoric acid, but removes the matching phosphoric acid solution of the material, which greatly improves the convenience of transportation and the safety of customer construction; The method improves the convenience of construction, retains the excellent performance of the material, and improves the ability of the material to resist infiltration and chemical erosion.

Abstract

The invention belongs to the technical field of refractory materials, and particularly relates to a water-added construction quick-drying repair castable and a preparation method thereof. The water-added construction quick-drying repair castable is prepared from, by weight, 65-75 parts of bauxite particles, 10-20 parts of bauxite fine powder, 5-7 parts of solid phosphoric acid and 6 parts of water. The raw materials are weighed in parts by mass, mixed, and uniformly stirred, vibration construction is conducted after stirring is completed, and sintering is conducted according to a standard heating curve, so that the quick-drying repair castable can be used, and by adding the solid phosphoric acid, all advantages and characteristics of the phosphoric acid combined quick-drying material are reserved, but a matched phosphoric acid solution of the material is removed, and thus the transportation convenience and the customer construction safety are greatly improved. Through water-added contruction, the construction convenience is improved, the excellent performance of the material is reserved, the infiltration resistance and chemical erosion resistance of the material are improved by adding water for construction, and the quick-drying repair castable is excellent in performance, safe in construction and suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of refractory materials, in particular to a quick-drying repair castable for construction with water and a preparation method thereof. Background technique [0002] Quick-drying repair castable is a kind of amorphous refractory material, which has the characteristics of high service temperature, no infiltration of molten aluminum, and no corundum reaction with molten aluminum. It is used in molten pools and slag lines in the non-ferrous aluminum melting industry. Generally speaking, this material has a higher service temperature and resistance to aluminum liquid infiltration than conventional castables. [0003] In the non-ferrous aluminum melting industry, the molten aluminum refractory will inevitably be damaged during use, especially the slag line of the entire furnace, which is most likely to be damaged. Once the refractory is damaged, in order to prevent the molten aluminum from penetrating The refract...
