Abstract
A kind of ferrovanadium dregs castable refractory, including the raw material of following portions by weight: 30～40 parts of aggregates, 55～60 parts of powders, 5～10 parts of additives, described aggregate is made up of ferrovanadium dregs, zircon and carborundum；Described powder is by vanadium iron slag charge powder, α～Al2O3Powder forms；Described additive is made up of hexamethylenetetramine, phenolic resin.
Description
Technical field
The invention belongs to technical field of refractory materials, particularly relate to a kind of ferrovanadium dregs castable refractory.
Background technology
At present, China's metallurgical industry develops rapidly, and the consumption of refractory material is increasing, but the resource that can be used for refractory material is fewer.Therefore, scientific and technical personnel are devoted to develop the resource that can be used as refractory material always.
Additionally, when utilizing v-bearing titanomagnetite smelting vanadium iron, substantial amounts of ferrovanadium dregs can be produced.Substantial amounts 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, the deficiency existed for prior art described above, it is provided that a kind of high-temperature behavior is good, the ferrovanadium dregs castable refractory of dispensing low cost.
A kind of ferrovanadium dregs castable refractory, including the raw material of following portions by weight: 30～40 parts of aggregates, 55～60 parts of powders, 5～10 parts of additives, described aggregate is made up of ferrovanadium dregs, zircon and carborundum；Described powder is by vanadium iron slag charge powder, α～Al2 O3Powder forms；Described additive is made up of hexamethylenetetramine, phenolic resin.
The solution have the advantages that: containing aluminium oxide and magnesium oxide in ferrovanadium dregs, zircon can improve resistance to spallation and the corrosion resistance of castable refractory, that is, zircon pyrolytic is zirconium oxide and silicon dioxide, silicon dioxide and magnesium oxide react and form forsterite, aluminium oxide reacts with magnesium oxide and carries out calcining and generates spinelle, simultaneous oxidation zirconium can make up the microcrack that microcrack produces, hexamethylenetetramine is as the firming agent of phenolic resin, when temperature reaches predetermined value, due to hexamethylenetetramine and phenolic resin effect, ferrovanadium dregs castable refractory quickly solidifies, and then it is rapidly achieved stable shape after improving the resistance to hash of ferrovanadium dregs castable refractory and corrosion resistance and the cast of ferrovanadium dregs castable refractory.
Detailed description of the invention
The technical solution adopted in the present invention is a certain proportion of aggregate, powder and additive to carry out mixing obtain ferrovanadium dregs castable refractory.Concretely:
A kind of ferrovanadium dregs castable refractory, including the raw material of following portions by weight: 30～40 parts of aggregates, 55～60 parts of powders, 5～10 parts of additives, described aggregate is made up of ferrovanadium dregs, zircon and carborundum；Described powder is by vanadium iron slag charge powder, α～Al2 O3Powder forms；Described additive is made up of hexamethylenetetramine, phenolic resin.Wherein, in described aggregate, the parts by weight of ferrovanadium dregs, zircon and carborundum are: vanadium iron slag charge 50 parts, zircon 25 parts and carborundum 25 parts；Vanadium iron slag charge powder, α～Al in described powder2 O3The parts by weight of powder are: 80 parts of vanadium iron slag charge powder, α～Al2 O320 parts of powder.Wherein, containing aluminium oxide and magnesium oxide in ferrovanadium dregs, zircon can improve resistance to spallation and the corrosion resistance of castable refractory, that is, zircon pyrolytic is zirconium oxide and silicon dioxide, silicon dioxide and magnesium oxide react and form forsterite, aluminium oxide reacts with magnesium oxide and carries out calcining and generates spinelle, simultaneous oxidation zirconium can make up the microcrack that microcrack produces, hexamethylenetetramine is as the firming agent of phenolic resin, when temperature reaches predetermined value, due to hexamethylenetetramine and phenolic resin effect, ferrovanadium dregs castable refractory quickly solidifies, and then it is rapidly achieved stable shape after improving the resistance to hash of ferrovanadium dregs castable refractory and corrosion resistance and the cast of ferrovanadium dregs castable refractory.
Wherein, vanadium iron slag charge, zircon and carborundum mixing post-treatment become coarse aggregate, middle aggregate and fine aggregate, and the size of described coarse aggregate is 1.5～2.0mm；In described middle aggregate, the size of each component is 1.0～1.5mm；The size of described fine aggregate is 0.4～0.3mm；The weight of coarse aggregate, middle aggregate and fine aggregate is coarse aggregate 30 parts, 40 parts of middle aggregate and fine aggregate 30 parts.
Above-mentioned ferrovanadium dregs castable refractory illustrated below:
