Abstract

The invention relates to a ferrovanadium slag and manganese slag castable. The ferrovanadium slag and manganese slag castable contains the following raw materials in parts by weight: 30-40 parts of aggregate, 40-50 parts of powder material and 5-10 parts of admixture, wherein the aggregate is prepared from ferrovanadium slag, zircon and silicon carbide; the powder material is prepared from ferrovanadium slag powder, alpha-Al2O3 powder and manganese slag powder; the admixture is composed of hexamethylenetetramine and phenol-formaldehyde resin.

Description

technical field [0001] The invention belongs to the technical field of refractory materials, and in particular relates to castables for vanadium-iron slag and manganese slag. 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 castable of vanadium-iron sl...
