Abstract
The invention discloses a slag collecting agent used for aluminium metallurgy. The slag collecting agent is characterized in that components of the slag collecting agent used for the aluminium metallurgy comprise, by mass, 74%-78% of perlite raw materials, 5%-12.0% of montmorillonite, 3%-5% of pyrophyllite, 10%-14% of albite, and 5%-15% of kaliophilite. The preparation comprises the steps that 1 weighing and mixing are conducted, raw materials are weighed and selected by weight according to the components, and the weighed raw materials are mixed evenly; 2 crushing is conducted, obtained mixed materials are put into a crusher to be crushed, and the fineness of the crushing ranges from 80 meshes to 100 meshes; 3 packing is conducted, crushed powder is packed in a sealed mode, and a product is finished. The blank of the slag collecting agent field of a domestic aluminium metallurgy industry is filled; the slag collecting agent has the advantages that the cost is low, the slag collecting effect is good, the slag removing time is short, and the consumption is small; in the using process, the slag collecting agent is free of the poison, the dust and the peculiar smell, and cannot pollute the environment.
Description
Technical field
The invention belongs to field of chemical metallurgical technology, relate to a kind of aluminium metallurgy poly-slag agent and preparation method thereof.
Background technology
Aluminum metal is had many uses, and it is prepared gained foundry goods and is widely used in the elasticity original paper of steam boiler, boats and ships and other machinery equipment and automobile and other industrial parts bearing friction.
In aluminium fusion process, because partial metal oxide product fusing point is lower than alloy melting temp, these oxide compounds is swum on metal aluminium liquid in liquid form, is not easily separated with aluminium liquid.If directly carry out skimming, slag-removing time can be caused long, operation not easily, has a large amount of aluminium liquid and runs off along with slag, cause loss to increase, cost increase, affect the production development of aluminium in process of simultaneously skimming.
For enhancing productivity, needing liquid slag caking to assemble before skimming, being beneficial to carry out effectively skimming fast, reducing copper loss in process of skimming simultaneously and lose.But use poly-slag agent mainly based on import volcanic ash at present, effect is general, and price also costly; Simultaneously domestic poly-slag agent product is also more rarely seen, and this causes use cost, and maintenance cost remains high, and limits the development of internal copper industry.Therefore, develop a kind of efficient poly-slag agent of applicable aluminium metallurgy industry, substitute external product, reduce production cost, the development of China's aluminium metallurgy industry is had important practical significance.
Summary of the invention
First technical problem to be solved by this invention is to provide the preparation method of the effective poly-slag agent of aluminium metallurgy of a kind of cheap, easy to use, poly-slag and poly-slag agent.
The present invention solves the technical scheme that above-mentioned first technical problem adopt: the poly-slag agent of a kind of aluminium metallurgy, is characterized in that: this aluminium metallurgy gathers the component of slag agent and mass percentage is: perlite raw material, 74%-78%; Montmorillonite, 5%-12.0%; Agalmatolite, 3%-5%; Albite, 10%-14%; Kaliophylite, 5%-15%.
As preferably, described component and mass percentage are: described component and mass percentage are: perlite raw material, 75%; Montmorillonite, 6%; Agalmatolite, 3%; Albite, 10%%; Kaliophylite, 6%.
Further, the grain graininess of described poly-slag agent is between 80-100 order.
The preparation method of described poly-slag agent, comprises the following steps: one, weigh mixing: take raw material by weight according to above-mentioned formula, and mixed by the raw material taken; Two, broken: gained compound is put into crusher and pulverizes, grinding particle size is between 80 order to 100 orders; Three, pack: gained powder bagging and packaging will be pulverized, be finished product.
Beneficial effect of the present invention is:
Poly-slag is effective, and after adding poly-slag agent of the present invention, liquid object floating on aluminium liquid can form slag rapidly, within 2 minutes, can skim, and impurity component obviously reduces simultaneously, improves the quality of product; Secondly, cost is low, uses the present invention to gather slag agent compare the cost that import gathers slag agent and reduce nearly 50% through measuring and calculating; This poly-slag agent can the dry moisture-proof role of teaching display stand, is beneficial in long-term warehouse and preserves.During use, in slag, copper loss is reduced to below 1kg/t by average 10kg/t; In use do not pollute the environment, nontoxic, dustless, free from extraneous odour.
