Abstract
The invention provides a refining agent capable of being used for purifying magnesium alloy liquid in the pressure casting process. The refining agent is composed of 36%-44% of magnesium chloride, 22%-28% of potassium chloride, 12%-18% of sodium chloride, 5% of light magnesium carbonate and 15%-20% of calcium fluoride. The refining agent special for a magnesium alloy is mainly composed of the magnesium chloride, the sodium chloride, the potassium chloride, the calcium fluoride and a proper amount of supplemented light magnesium carbonate; a raw material is common salt, heavy metal barium salt is not contained, and the refining agent is a complete and environment-friendly green fusion agent; after the fusion agent is subject to refining reaction, suspension oxidation impurities in the magnesium alloy liquid will be absorbed and rapidly deposit to the bottom of the liquid to form hard blocks, a pressure casting crucible is convenient to remove, and influences on the follow-up process of the pressure casting operation are avoided; the refining agent contains the light magnesium carbonate, carbon dioxide gas can be generated in the refining processing process, and the gas content in the alloy liquid is accordingly purified.
Description
Technical field:
The present invention relates to a kind of refining agent and the production technique thereof that can be used for purifying in pressure die casting process liquid magnesium alloy, it belongs to technical field of metal.
Background technology:
Density is little, specific tenacity is high, specific modulus is high because having for magnesium alloy, shock-absorbing, corrosion-resistant, anti-electromagnetic interference capability Qiang good moldability and the good characteristic of product thermodiffusion performance, the fields such as Aeronautics and Astronautics, automobile, communications electronics are widely used in, particularly electronic product in recent years is universal, and the characteristic that magnesium alloy is many, magnesium alloy is applied on 3C electronic product more and more extensive.
The application of magnesium alloy on 3C communication products; equally based on the maturation of magnesium alloy microdiecast moulding process; during the casting of magnesium alloy precision pressure; due to the problem such as running fit of air seal protection problem or die casting equipment; High Temperature Magnesium Alloy liquid pure cleanliness in die casting crucible is easily caused to be affected; thus cause the bad of die casting quality product, do not reach the requirement of setting.And now conventional refining agent used for magnesium alloy, just just can apply when doing magnesium alloy, if be used in die casting earthenware crucible, then due to the flux slag liquid that finally produces can not sedimentation completely in time with clear out, and then cause impact on die casting equipment, die casting operation, and then affect the quality of product.
Summary of the invention:
The invention provides a kind of refining agent and the production technique thereof that can be used for purifying in pressure die casting process liquid magnesium alloy, is on the basis based on the refining flux of magnesium alloy, by regulating proportioning, introducing new material produce and forming.
The present invention adopts following technical scheme: a kind ofly can be used for the refining agent purifying liquid magnesium alloy in pressure die casting process, is made up of: magnesium chloride 36-44% following component; Repone K: 22-28%; Sodium-chlor: 12-18%; Magnesium Carbonate Light 41-45: 5%; Calcium Fluoride (Fluorspan) 15-20%.
The present invention also adopts following technical scheme: a kind of production technique that can be used for the refining agent purifying liquid magnesium alloy in pressure die casting process, it comprises the steps:
1. configure required material by the production program;
2. first in crucible, add Repone K and sodium-chlor compound, then add one deck magnesium chloride;
3. crucible inner melt temperature reaches 730-750 when spending, and joins in bell jar, along the slowly movement of flux pot wall, play except crystal water by the charcoal of drying, then drags for scum silica frost clearly with the slag spoon that drags for after preheating;
4.750-780 degree begins to start casting, and being broken into maximum grade after cooling is 8 object granulars;
5. by lightweight carbonic acid carbon and Calcium Fluoride (Fluorspan) and broken good flux powder join in proportion in Stirring bucket and stir;
6. the woven bag of satisfactory product with internal layer membrane courage encapsulates, and prevents the moisture absorption.
The present invention has following beneficial effect:
(1) the special refining agent of magnesium alloy of the present invention is primarily of magnesium chloride, sodium-chlor, Repone K and Calcium Fluoride (Fluorspan), is aided with appropriate Magnesium Carbonate Light 41-45 composition; Raw material is common salt, not containing heavy metal barium class salt, is the green flux of complete environmental protection;
(2) after this kind of flux carries out purifying reaction, the suspension oxidation impurity in liquid magnesium alloy can be adsorbed, and be deposited to liquid bottom very soon, form lump shape, be convenient to clear out of die casting crucible, impact not formed on the subsequent technique of die casting operation;
(3) contain Magnesium Carbonate Light 41-45 in this refining agent, in refining process, can carbon dioxide be produced, thus the gas content in purification aluminium alloy;
(4) carbon dioxide is after reacting with magnesium liquid, can produce without ingot shape carbon, thus alloy liquid plays metamorphism, the material property of optimized alloy liquid;
(5) carbon dioxide produced can play a protective effect to metal liquid.
Embodiment:
