Abstract
The invention discloses a preparation method of a non-ferrous metal refining agent and belongs to the field of non-ferrous metals. The preparation method comprises the following steps: (1) preparation of the refining agent, wherein the refining agent comprises the following components in percentage by mass: 35 percent of NaNO3, 5 percent of C, 19 percent of Na3AlF6, 11 percent of NaCl and 30 percent of refractory brick chips; (2) powdering of a material; (3) pressing of the refining agent; (4) baking of the refining agent, to be specific, the refining agent pressed into a cake shape is placed into a baking chamber to be baked so as to remove moisture in the refining agent. The preparation method solves the problems of incompleteness of refining caused by a poor acting effect of the refining agent in the refining process of existing molten aluminum, and has the advantages of simple method, low cost and easiness for processing.
Description
Technical field
The invention belongs to non-ferrous metal field, more particularly, relate to a kind of preparation method of the refining agent for aluminum anodizing.
Background technology
Al and Alalloy is one of very extensive, most economical applicable material of current applications.The density of aluminium is less, though hardness is low, can be made into various aluminium alloy, as duralumin, ultralumin, corrosion-resisting aluminium, cast aluminium etc.These aluminium alloys are widely used in the process industries such as aircraft, automobile, train, boats and ships.In addition, cosmic rocket, space shuttle, man-made satellite also use a large amount of aluminium and aluminium alloy thereof.
The electroconductibility of aluminium is only second to silver, copper and gold, has been widely used in electrical equipment process industry, electric wire industry and radio industry.Aluminium is the good conductor of heat, and industrial available aluminium manufactures various heat exchanger, heat sink material and cooker etc.Aluminium has good ductility (its ductility is only second to Jin Heyin), is widely used in containers of cigarettes, candy etc., also can be made into aluminium wire, aluminum strip, and can the various aluminum products of rolling.The surface of aluminium, because there being fine and close oxide film, being not easily corroded, being often used to manufacturing chemistry reactor, medicine equipment, freezing plant, petroleum refining device, oil and natural gas pipeline etc.
And in the preparation process of aluminium, need to carry out refining to aluminium, its objective is the inclusion in order to remove in aluminium, to improve the purity of aluminium.But at present for the refining of aluminium, the manufacturing process usually due to refining agent is immature, and causes refining in aluminum anodizing process not thorough.
Summary of the invention
For existing aluminium liquid in the process of refining, because the action effect of refining agent is not good, and cause the halfway problem of refining, the invention provides a kind of preparation method of non-ferrous metal refining agent, by reconfiguring the composition of refining agent, refining effect is improved, solves the halfway problem of refining.
For solving the problem, the present invention adopts following technical scheme.
A preparation method for non-ferrous metal refining agent, comprises the following steps:
(1) configuration of refining agent:
In refining agent, the mass percent of each component is: NaNO
3: 35%, C:5%, Na
3alF
6: 19%, NaCl:11%, refractory brick bits: 30%;
(2) powdered of material:
After being configured refining agent according to step (1), pulverizer is utilized to be pulverized;
(3) compacting of refining agent:
Add suitable quantity of water in refining agent after powdered, utilize pressing machinery to suppress, be pressed into pie, the diameter range of pie refining agent is 135-150mm;
(4) baking of refining agent:
Caked refining agent is put into baking box toast, removing moisture wherein.
Preferably, in described step (3), the diameter of pie refining agent is 140mm.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention is by reconfiguring the composition of refining agent, and refining effect is improved.
(2) the inventive method is simple, and cost is low, handling ease.
Embodiment
Describe the present invention below in conjunction with embodiment.
