Abstract
The present invention discloses a kind of novel refining agent and preparation method thereof, including sodium chloride, potassium chloride, prodan, carbon trichloride, sodium nitrate, the sodium chloride 20-30%, the potassium chloride 20-30%, the prodan 20-30%, the carbon trichloride 20-30%, the sodium nitrate 20-30%, sodium chloride in refining agent of the invention is extremely easy in decomposition at high temperature, the gas of generation is easy to hydrogen reaction, and with slag inclusion strong adsorption force, and it is escaped from melt rapidly, prodan, carbon trichloride, sodium nitrate has slag-cleaning agent effect concurrently, liquid, it can effectively sufficiently be contacted with molten aluminum, remove the slag inclusion in molten aluminum.
Description
Technical field
The present invention relates to a kind of novel refining agents and preparation method thereof, belong to the technical field of refining agent.
Background technique
In aluminum current and aluminium alloy production process, a certain amount of waste material is generally all added, simultaneously because aluminium and its alloy exist
It is easy to aoxidize, absorb the characteristic of gas in melting, casting process, so that gas and field trash are easily formed in molten aluminum, in aluminium
In alloy refining production, need to carry out sufficient purified treatment to the inside dregs of aluminium alloy, refining agent is mainly used for removing
Hydrogen inside molten aluminum and the oxide slag inclusion to swim, keep molten aluminum purer, and have the part group in the effect refining agent of slag-cleaning agent concurrently
Member is extremely easy in decomposition at high temperature, and the gas of generation is easy to hydrogen reaction, and with slag inclusion strong adsorption force, and escaped from melt rapidly.
Other constituent elements have slag-cleaning agent effect concurrently.
Summary of the invention
Goal of the invention: above-mentioned in order to overcome the problems, such as to need, the present invention provides a kind of novel refining agent and preparation method thereof.
Process program: the present invention discloses a kind of novel refining agent and preparation method thereof, including sodium chloride, potassium chloride, fluorine silicon
Sour sodium, carbon trichloride, sodium nitrate, the sodium chloride 20-30%, the potassium chloride 20-30%, the prodan 20-30%,
The carbon trichloride 20-30%, the sodium nitrate 20-30%.
A kind of preparation method of novel refining agent, which comprises the steps of:
Step 1: sodium chloride, potassium chloride, prodan, carbon trichloride, sodium nitrate are carried out ingredient；
It is melted step 2: the sodium chloride prepared, potassium chloride, prodan, carbon trichloride, sodium nitrate are fitted into furnace
Change；
Step 3: cooling after whole is melt-blended use.
Further, described melt by the material prepared and be screened by slipping through the net.
The invention has the following advantages that
1, the sodium chloride in refining agent is extremely easy in decomposition at high temperature, and the gas of generation is easy to hydrogen reaction, and adsorbs with slag inclusion
Power is strong, and escapes from melt rapidly, and prodan, carbon trichloride, sodium nitrate have slag-cleaning agent effect concurrently；
2, refining agent is largely liquid, can effectively sufficiently be contacted with molten aluminum, and the slag inclusion in molten aluminum is removed.
Detailed description of the invention
A kind of Fig. 1: structural block diagram of the preparation method of novel refining agent of the present embodiment.
Specific embodiment
The present invention is further elaborated below in conjunction with attached drawing and by specific embodiment, it should be pointed out that: for this technique
For the common process personnel in field, without departing from the principle of the present invention, to repairing for various equivalent forms of the invention
Change and falls within the application range as defined in the appended claims.
Embodiment 1:
The present invention discloses a kind of novel refining agent and preparation method thereof as shown in Figure 1, which is characterized in that including walking as follows
It is rapid:
Step 1: carrying out sodium chloride, potassium chloride, prodan, carbon trichloride, sodium nitrate by sodium chloride 20-30%, institute
Potassium chloride 20-30%, the prodan 20-30%, the carbon trichloride 20-30% are stated, the sodium nitrate 20-30% is carried out
Ingredient；
It is melted step 2: the sodium chloride prepared, potassium chloride, prodan, carbon trichloride, sodium nitrate are fitted into furnace
Change, it is described melt by the material prepared and be screened by slipping through the net；
Step 3: cooling after whole is melt-blended use.
The invention has the following advantages that
1, the sodium chloride in refining agent is extremely easy in decomposition at high temperature, and the gas of generation is easy to hydrogen reaction, and adsorbs with slag inclusion
Power is strong, and escapes from melt rapidly, and prodan, carbon trichloride, sodium nitrate have slag-cleaning agent effect concurrently；
2, refining agent is largely liquid, can effectively sufficiently be contacted with molten aluminum, and the slag inclusion in molten aluminum is removed.
