Description
Technical field
The present invention relates to aluminum silicon alloy casting field, be specifically related to a kind of aluminum-silicon alloy refining agent; The present invention also relates to a kind of preparation method of aluminum-silicon alloy refining agent simultaneously.
Background technology
The features such as electric heating process is produced aluminum silicon alloy and had that density is low, intensity is high, wear-resisting and good heat resistance.In addition, the coefficient of expansion of aluminum silicon alloy is little, and thermostability is high, or a kind of good structured material, is widely used in the industries such as automobile, motorcycle, tractor, steamer, engineering machinery, electric power, metallurgy and household electrical appliance.
At present, the method for producing aluminum silicon alloy mainly contains two kinds, namely converts the method for mixing and electric heating process.Converting the method for mixing is that the industrial silicon of metallic aluminium and the electric heating process production of electrolytic process being produced is through heavily refining, mix, mix and making.Electric heating process to contain Al

3and SiO
2ore and reductive agent bituminous coal, refinery coke after preparing burden, make agglomerate, melting in ore-smelting furnace is added after drying, first make containing Al56% ~ 64%, containing the primary aluminum-silicon alloy of the impurity such as Si36% ~ 40% and a small amount of Fe, Ti, Ca, after refining, add part fine aluminium again to dilute, make the aluminum silicon alloy of the required various trades mark.
Because it is wide that electric heating process has raw material sources, capacity usage ratio is high, and power consumption is few, and environmental pollution is little and easily administer, the advantages such as production cost is lower.But impure more in the aluminum silicon alloy adopting electric heating process to produce, if removal of impurities not in time, aluminum silicon alloy surface there will be being mingled with of pore and oxide compound, makes the quality of aluminum silicon alloy product can not be guaranteed, sometimes even can cause scrapping of product.
Summary of the invention
The object of this invention is to provide a kind of aluminum-silicon alloy refining agent that can reduce foreign matter content in electric heating process production aluminum silicon alloy.
The present invention also aims to the preparation method that a kind of aluminum-silicon alloy refining agent is provided.
In order to realize above object, the technical solution adopted in the present invention is: the aluminum-silicon alloy refining agent that a kind of electric heating process is produced, and is made up: NaCl55% ~ 70%, NaAlF of the raw material of following weight percentage
620% ~ 35%, KCl3% ~ 10%, MgCl
23% ~ 10%.
The aluminum-silicon alloy refining agent that described electric heating process is produced, is made up of the raw material of following weight percentage: NaCl60% ~ 65%, NaAlF
625% ~ 30%, KCl3% ~ 5%, MgCl
23% ~ 5%.
The aluminum-silicon alloy refining agent that described electric heating process is produced, is made up of the raw material of following weight percentage: NaCl65%, NaAlF
627%, KCl3%, MgCl
25%.
A preparation method for the aluminum-silicon alloy refining agent that electric heating process is produced, comprises the following steps:
(1) by NaCl heat drying, the moisture content of NaCl is made to be reduced to 1%;
(2) percentage composition takes following raw material by weight: NaCl60% ~ 65%, NaAlF
625% ~ 30%, KCl3% ~ 5%, MgCl
23% ~ 5%, all raw materials are mixed and stirs;
(3) raw material stirred is packed according to every 5kg mono-bag, and be placed in dry environment preservation.
The using method of described aluminum-silicon alloy refining agent: by the refining agent prepared according to 1% ~ 1.2% ratio join in the initial alloy that electric heating process produces, stir while adding, to be mixed evenly after, leave standstill and can cast after 20 minutes.
Existing aluminum refining agent mainly for mix different substances together method method produce aluminium alloy configuration, because foreign matter content in electric heating process production aluminum silicon alloy is more than 5%, impurity is larger, utilize existing refining agent can not effectively removal of impurities, refining agent large usage quantity simultaneously, refining agent of the present invention effectively can remove the aluminum silicon alloy of high impurity content.
Aluminum-silicon alloy refining agent provided by the invention is by adding a certain proportion of NaCl, NaAlF
6, KCl, MgCl
2, after refining is carried out to primary aluminum-silicon alloy, greatly can reduce the content of impurity in aluminum silicon alloy product, as can by the impurity CaSiO in alloy
3and Al
