Embodiment 1

[0024] Use special-grade high-alumina vanadium clinker: ≤1-5mm, ratio: 65%, as aggregate, start and stir for 1-2 minutes, so that the aggregate is spread on the bottom of the mixing tank, and then add brown corundum fine powder: -200 Project, score: 27%; α-AI 2 o 3 Micropowder: -5mm, Score: 5%; SiO 2 Micropowder: 1um, proportion: 3%, stir for 6-10 minutes until it reaches a uniform state, then discharge, bag and pack. When in use, add phosphoric acid with a concentration of 45% (additional), the ratio: 15%, and stir evenly before use.

Embodiment 2

[0026] Use brown corundum particles: ≤0.01-5mm, ratio: 65%, as aggregate, start stirring for 1-2 minutes, make the aggregate spread on the bottom of the mixing tank, and then add white corundum fine powder: -200 mesh, ratio: 21.5%; α-AI 2 o 3 Micropowder: -5mm, ratio: 10%; SiO2 micropowder: 1um, ratio: 3%; preservative: 0.5%; solid aluminum dihydrogen phosphate (additional): 5%, stir for 6-10 minutes until uniform, then put Material, bagging, packaging. When using, add water (additional), the proportion: 5-10%, stir evenly and then use.

Abstract

The present invention is hot cast high temperature wear resistant ceramic material is one anti-wear refractory material suitable for fast hot repair of tertiary air duct, high temperature air duct, high temperature dust collector, etc in cement producing apparatus as well as thermal apparatus in iron and steel works, power plant, etc. The hot cast high temperature wear resistant ceramic material is powder comprising high alumina anti-wear refractory material as the aggregate, phosphate, phosphoric acid and aluminum dihydrogen phosphate as the binding agent, and additive. It has convenient repair construction process, high flowability, high strength, high heat resistance, high wear resistance, and high heat shock resistance.

Description

technical field [0001] The invention relates to a high-temperature thermal equipment lined with wear-resistant ceramic material, especially a thermal state material for tertiary air ducts, high-temperature air ducts and high-temperature dust collectors in cement industry, power plants, steel plants, mining factories, and glass factories. Unshaped refractory and wear-resistant materials for rapid pouring repair under certain circumstances. technical background [0002] Cement industry, tertiary air duct, high-temperature air duct and high-temperature dust collector lining are under the action of high temperature (300-600°C) and high-speed medium erosion and wear, the lining material will be damaged soon, and the service life is short. If you stop and cool down Re-repair will greatly affect production efficiency and output. Therefore, it is required to develop a new material that can be poured and repaired in a hot state (300-600°C) without stopping production. Contents of t...
