Problems solved by technology

However, this kind of castable has low hardness and poor wear resistance; at the same time, the castable has poor fluidity, solidifies too quickly, and has low early bonding strength, which seriously affects the performance of the product at medium and low temperatures below 900 °C, which poses a threat to the safety of molten salt furnaces. Production brings great hidden dangers. In addition, it is not easy to construct, so it still needs to be improved

Abstract

The invention aims at providing castable for aluminum industry. The castable is good in construction performance and high in strength and can remove impurities such as iron oxide in materials. The castable which can achieve the high CO erosion resistance, the good wear resistance and the good construction performance in a strong reducing atmosphere and always has the good performance at medium temperature, low temperature and high temperature is finally obtained.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a casting material for the aluminum industry. Background technique [0002] The characteristics of high alumina, high silicon, poor grindability and difficult dissolution in my country's durasite-type bauxite have brought great troubles to the alumina production process. For now, the pipeline dissolution method has gradually become a The development trend, and the molten salt furnace is the most critical heating equipment in the pipeline dissolution system. [0003] At present, the hearth of the molten salt furnace in an alumina plant is usually integrally cast with high-alumina refractory castables, which makes the structure of the furnace lining very loose or even cracked. In the process of use, the strong erosion of high-temperature flue gas and coal ash, and the fluctuation of furnace temperature will cause serious erosion of the furnace lining and ca...
