Abstract
The present invention discloses the production technology of a large diameter aluminium alloy circular cast ingot. In the present invention, primary aluminium, intermediate alloy and a magnesium ingot are mixed, and then, the mixture is smelted; the primary aluminium, the magnesium ingot, the aluminum-silicon intermediate alloy, chromium additives and manganese additives are weighed according to the chemical composition of a product; then, the raw materials are loaded in a smelting furnace to be smelted so that the raw materials are melted; after the raw materials are agitated, the slag is removed, a sample is taken to be tested; the raw materials is injected into a heat retaining furnace to be refined, and the raw materials are statically placed after degassing, deslagging, agitation and slag removal and are filtered; finally, a product is cast. The present invention has the advantages of stable chemical composition, smooth product appearance, compact and even grain structure, good extrusion characteristics, etc. The diameter of the cast ingot can reach 380mm, product quality is better than that of an abroad similar product, and the performance of extrusion section strength, etc. can completely meet the requirement for a large structural member.
Description
Technical field:
The present invention relates to a kind of production technique of aluminium alloy cast ingot.
Background technology:
Domestic aluminium section bar production at present turns to the manufacture material from the production small sized product gradually, particularly communications and transportation develops with the section bar direction, has correspondingly built some special extruding rail vehicles, railcar, vehicle section bar or to produce the factory of this class section bar.And, mainly still relying on import now for raw material---the aluminium alloy extruded round ingot casting of various high-qualitys of producing these products, domestic manufacturer can't produce.
Summary of the invention:
The objective of the invention is to: provide a kind of method of producing large diameter aluminium alloy extruding circle ingot casting, to satisfy the needs that domestic industry is produced.
The present invention is achieved in that it is that primary aluminum, master alloy, magnesium ingot are prepared burden, smelt then, the moiety weighing that primary aluminum, magnesium ingot, aluminium-silicon master alloy, chrome additive, manganese additive are pressed product, the smelting furnace melting of then primary aluminum, aluminium-silicon master alloy being packed into, controlled temperature is at 750 ℃～760 ℃, treat after alloy fully melts chrome additive, manganese additive, magnesium ingot to be pressed in the aluminium liquid with bell jar respectively, make its fusing, after stirring, skimming, sample examination, metaideophone is gone into holding furnace again; In holding furnace, dust liquation is carried out refining, degasification, slagging-off, leave standstill after stirring, skimming with nitrogen; Liquation uses the online crystal grain thinning of Al-Ti-B line bar, and through ceramic filter; At last liquation is carried out the lubricated Gas Curtain Casting of oil, gas with vertical casting machine and go out product.
The present invention compared with prior art has advantages such as chemical composition stability, product appearance is smooth, crystalline-granular texture is fine and close evenly, and compression properties is good.Its diameter can reach 380mm, and quality product is better than external like product, and performances such as extruded section intensity can satisfy the requirement of large-sized structural parts fully.
Embodiment:
Embodiments of the invention: with primary aluminum (iron content 0.15～0.25%) 17380kg, master alloy ZLD102 (siliceous 10～13%) 1152kg, melting in smelting furnace earlier, controlled temperature is at 750 ℃～760 ℃, stir, treat that alloy fully melts the back and adds manganese additive (manganese content 75%) 38.2kg, be pressed in the aluminium liquid with bell jar, add chrome additive (chromium content 75%) 32.4kg again, be pressed in the aluminium liquid, again magnesium ingot (magnesium 〉=98.5%) 105.6kg is added with bell jar, be pressed in the aluminium liquid with bell jar, stir then, add slag former, skim behind the restir, sample examination, after qualified the liquation metaideophone is gone into holding furnace, in holding furnace, dust liquation is carried out refining, degasification again with nitrogen, slagging-off, stir, leave standstill after skimming; Liquation is used Al-Ti-B line bar crystal grain thinning again, and through ceramic filter; At last liquation is carried out the lubricated Gas Curtain Casting of oil, gas with vertical casting machine and go out product.
