Problems solved by technology

[0003] Bauxite, magnesite and graphite are the three major refractory raw materials. However, due to disorderly mining, low level of processing technology, low level of comprehensive utilization of resources, and serious waste, the above-mentioned mineral resources, especially high-grade refractory raw material resources It has become less and less, resource conservation and comprehensive utilization of resources have become the top priority

Abstract

Corundum slag, industrial sludge from aluminum profile factory, magnesia, aluminum ash, silicon carbide, kaolin fine powder, zinc aluminum spinel fine powder, dolomite, serpentine, zirconia, yttrium oxide, sodium hexametaphosphate, Sodium tripolyphosphate and pure calcium aluminate cement are used as raw materials to prepare refractory castables with excellent performance and low production cost, achieving the purpose of comprehensively recycling corundum slag and fly ash of thermal power plants and reducing production costs; the obtained corundum slag ‑Performance indicators of fly ash refractory castables for thermal power plants: after drying at 110°C for 24 hours, the compressive strength at room temperature is 30.2‑34.7MPa; after calcination at 1350°C for 3 hours, the compressive strength at room temperature is 180‑220MPa, and the bulk density is 3.2‑3.7g / cm3.

Description

technical field [0001] The invention belongs to the field of refractory materials, in particular to a corundum slag-aluminum profile factory industrial sludge refractory castable. Background technique [0002] Unshaped refractories are bulk heat-resistant materials that are not fired at high temperatures, including castables, ramming materials, plastics, gunning materials, smearing materials, projection materials, pressing materials, fire clay and other products. It is an important branch of refractory materials and is known as the second generation of refractory materials. The rapid development of unshaped refractories has become an irreplaceable material in industrial production such as metallurgy and chemical industry, which has promoted the transformation of industrial kilns and the development of refractory materials. In the refractory industry, the proportion of shaped refractory materials is decreasing year by year, while the proportion of unshaped refractory materia...
