Description
Technical Field
The invention relates to the technical field of granulation molding, in particular to a binder and a preparation method and application thereof.
Background
The method for producing high titanium slag by smelting titanium concentrate in an electric furnace is a main method for treating titanium raw materials, and is characterized in that the existing titanium slag electric furnace of a titanium smelting plant of a steel share company is 3, 25 ten thousand tons of titanium concentrate are treated annually, and 14 ten thousand tons of high titanium slag are produced annually.
In actual production, because the titanium concentrate has an excessively fine particle size (the proportion of particles below 200 meshes is more than 75%), fine particles are easily sucked into a flue by an air suction system and enter a dust removal system in the smelting process in a furnace to form dust removal ash, 1.5 million tons of dust removal ash are generated in a titanium smelting plant every year, the raw material loss is large, a certain amount of expenditure is required for processing the dust removal ash, the economic loss is caused, and the production cost is increased.
On the other hand, the titanium concentrate powder is directly smelted in the electric furnace, so that fine powder enters a flue along with furnace gas, the flue and a furnace gas treatment system are frequently blocked, and production stop and cleaning are required, so that the smooth operation of production is influenced, and the production efficiency is reduced; in addition, fine powders are very prone to dust emission during transportation, resulting in deterioration of production environment.
In order to reduce the loss of the titanium concentrate powder and promote the smooth smelting of the electric furnace, the titanium concentrate is granulated and then enters the furnace, so that the blockage of a dust removal pipeline can be relieved to a certain extent and the generation amount of dust removal ash can be reduced.
Similarly, a large amount of by-products such as dust, etc., such as enriched sludge, converter fly ash, etc., are generated inside the steel plant. The dust is rich in iron, so the dust is also a precious secondary resource, and the utilization of the resource is an important way for improving the utilization efficiency of the resource, reducing the cost and improving the efficiency. At present, secondary resources such as enriched sludge rich in iron, converter fly ash and the like are mostly used as vanadium extraction cooling agents and converter slagging agents after agglomeration,
in summary, since the secondary resources are mostly powder materials, the amount of dust generated directly is large, and the air permeability is affected, the prior art needs to use the powder materials after agglomeration; however, the cost of the caking agent for agglomeration is high, and the large-scale utilization of secondary resources is restricted to a certain extent.
