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
The invention belongs to technical field of refractory materials, particularly relate to a kind of ferrovanadium dregs refractory castable.
Background technology
At present, China's metallurgical industry develops rapidly, and the consumption of refractory materials is increasing, but the resource that can be used for refractory materials is fewer.Therefore, scientific and technical personnel are devoted to develop the resource that can be used as refractory materials always.
In addition, when utilizing v-bearing titanomagnetite smelting vanadium iron, a large amount of ferrovanadium dregs can be produced.A large amount of ferrovanadium dregs is piled up and cannot be recycled utilization, and this not only causes the pollution of environment, and causes the waste of resource.
Summary of the invention
In view of this, for the deficiency that the above prior art exists, provide the ferrovanadium dregs refractory castable that a kind of high-temperature behavior is good, batching cost is low.
A kind of ferrovanadium dregs refractory castable, comprise the raw material of following portions by weight: 30 ~ 40 parts of aggregates, 55 ~ 60 parts of powders, 5 ~ 10 parts of admixtures, described aggregate is made up of ferrovanadium dregs, zircon and silicon carbide; Described powder is by vanadium iron slag charge powder, α ~ Al
2o
3powder forms; Described admixture is made up of hexamethylenetetramine, resol.
Technique effect of the present invention is: containing aluminum oxide and magnesium oxide in ferrovanadium dregs, zircon can improve resistance to spallation and the erosion resistance of refractory castable, that is, zircon pyrolytic decomposition is zirconium white and silicon-dioxide, silicon-dioxide and magnesium oxide react and form forsterite, aluminum oxide and magnesium oxide react and carry out calcining and generates spinel, simultaneous oxidation zirconium can make up the microfracture that microfracture produces, hexamethylenetetramine is as the solidifying agent of resol, when temperature reaches preset value, due to hexamethylenetetramine and resol effect, ferrovanadium dregs refractory castable solidifies very soon, and then reach stable shape fast after improving the resistance to hash of ferrovanadium dregs refractory castable and erosion resistance and the cast of ferrovanadium dregs refractory castable.
Embodiment
The technical solution adopted in the present invention a certain proportion of aggregate, powder and admixture is carried out mixing to obtain ferrovanadium dregs refractory castable.Concretely:
