Abstract
The invention discloses a manufacturing process of an aluminum alloy tensile bolt. Two molten aluminum alloy components are synchronously smelted in two medium-frequency furnaces, and respectively comprise the following component ranges in percentage by mass: a bolt head part: 1.20-1.35% of C, 1.5-1.8% of Mo, 0.8-1.0% of Si, S not more than 0.05%, and P not more than 0.05%; and a bolt column part: 0.9-1.10% of C, 1.2-1.5% of Mo, 0.6-1.0% of Si, S not more than 0.05%, and P not more than 0.07%; and the metallurgy temperature reaches 800-900 DEG C. The manufacturing process can effectively solve the technical difficulties; and the tensile bolt further improves the tensile property and other mechanical performances.
Description
Technical field
The present invention relates to field of aluminum alloys, particularly relate to a kind of aluminium alloy tension bolt manufacture craft.
Background technology
Along with a large amount of uses of aluminium alloy, it is found that its wear resistance affects by various factors.Wherein first one be the impact of carbon content.Under the same conditions, carbon content is (0.8% ~ 1.4%) and the proportional linear relationship of wear resistance within the specific limits, and namely carbon content improves, and wear resistance strengthens.But along with carbon content improves, the toughness of high mangaenese steel sharply reduces.And the Working environment of bolt head is very high to toughness reserve requirements.Next is the impact of casting technique, and high mangaenese steel resolidified region is wider, forms shrinkage porosite tendency larger, and adopting at present increases speed of cooling, as used chill.Increase feeding capacity, strengthen rising head etc.Singly be limited to sand casting process restriction, these methods all produce little effect, and cannot solve an above-mentioned difficult problem at all.
Summary of the invention
The invention provides a kind of aluminium alloy tension bolt manufacture craft, can effectively solve above-mentioned technical barrier, the tensile property of tension bolt improves further, and other mechanical properties are also improved further simultaneously.
Technical scheme of the present invention is as follows:
A kind of aluminium alloy tension bolt manufacture craft, in two intermediate frequency furnaces, smelt two kinds of composition molten aluminium alloy, each composition range is respectively by percentage to the quality simultaneously: bolt head part C:1.20 ~ 1.35%, Mo:1.5 ~ 1.8%, Si:0.8 ~ 1.0%, S≤0.05%, P≤0.05%; Hitching post part C:0.9 ~ 1.10%, Mo:1.2 ~ 1.5%, Si:0.6 ~ 1.0%, S≤0.05%, P≤0.07%, metallurgical temperature reaches 800 ~ 900 DEG C, add alloy furnace charge adjusting component to acceptability limit, deoxidation step is carried out in stove, Modulating Power is that temperature remains on 1100 ± 20 DEG C, and start cast, molten steel steadily enters die cavity by bottom filling running channel under the influence of centrifugal force, liquation quick solidification under the chilling action of metal mold is shaping, and control pouring speed is 10-12g/s.
Each composition range is respectively by percentage to the quality: bolt head part C:1.27%, Mo:1.65%, Si:0.9%, S:0.03%, P:0.02%; Hitching post part C:1%, Mo:1.35%, Si:0.8%, S:0.02%, P:0.03%.
The invention has the beneficial effects as follows:
The tension bolt of the present invention's two kinds of composition al alloy component castings, the tensile property of worn area (1) tension bolt improves further, and other mechanical properties are also improved further simultaneously.(2) be that Toughness Ratio is better, given full play to material advantage separately, avoided respective shortcoming simultaneously, significantly improve the work-ing life of bolt.
