Abstract

The invention discloses ferrovanadium slag refractory castable. The ferrovanadium slag refractory castable comprises the following raw materials in parts by weight: 30-40 parts of aggregates, 55-60 parts of powder and 5-10 parts of admixtures, wherein the aggregates consist of ferrovanadium slag, zircon and silicon carbide; and the powder consists of ferrovanadium slag powder and alpha-Al2O3 powder; and the admixtures consist of hexamethylene tetramine and phenolic resin.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to a ferrovanadium slag refractory castable. Background technique [0002] At present, with the rapid development of my country's metallurgical industry, the consumption of refractory materials is increasing, but the resources available for refractory materials are relatively small. Therefore, scientific and technical personnel have been working hard to develop resources that can be used as refractory materials. [0003] In addition, when using vanadium-titanium magnetite to smelt ferrovanadium, a large amount of ferrovanadium slag will be produced. A large amount of ferrovanadium slag is piled up and cannot be recycled, which not only causes environmental pollution, but also causes waste of resources. Contents of the invention [0004] In view of this, aiming at the deficiencies in the above-mentioned prior art, a vanadium iron slag refractory castable ...
