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 a kind of high-temperature behavior is good, batching cost is low ferrovanadium dregs and manganese slag mould material.
A kind of ferrovanadium dregs and manganese slag mould material, comprise the raw material of following portions by weight: 30 ~ 40 parts of aggregates, 40 ~ 50 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, manganese ground-slag form; Described admixture is made up of hexamethylenetetramine, resol.
Technique effect of the present invention is: containing aluminum oxide and magnesium oxide in ferrovanadium dregs, containing aluminum oxide and silicon-dioxide in manganese slag, 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 and manganese slag mould material are solidified very soon, and then reach stable shape fast after improving the resistance to hash of ferrovanadium dregs and manganese slag mould material and erosion resistance and ferrovanadium dregs and the cast of manganese slag mould material.
