Abstract
The invention discloses a new technology for production of an aluminum bronze-steel bimetallic bearing material. The technology is characterized in that: the novel aluminum bronze comprises the following chemical components: 7.4% of Al, 3% of Fe, 0.2% of Mn, 0.5% of Ni, and the balance Cu. A solid phase bonding method is employed to produce the aluminum bronze-steel bimetallic material, and a red copper sheet is used as an intermediate transition layer to improve the bonding strength. The melting process is optimized, then rolling and heat treatment are carried out, and then composite rolling of aluminum bronze and red copper sheet is conducted, and the step is one of the key processes of the technology. Then annealing is performed, the alloy avoids expensive tin and toxic lead, thus being consistent with the national policy of saving scarce resources and protecting the environment. The new technology brings the aluminum bronze-steel bimetallic bearing material to industrialization and lets it become one of the mainstream bearing materials in the future used for high load and high rotation speed engines, and the material has broad market prospects.
Description
Technical field
The invention discloses a kind of new technology of producing aluminum bronze-steel dual-metal bearing material.
Background technology
Aluminium bronze refers to and in binary aluminium bronze alloy, adds the elements such as iron, manganese, nickel and the polynary complex aluminium bronze that forms.Aluminium bronze have this is as high in fatigue resistance, corrosion-proof wear performance is good, hot operation stability, is a kind of ideal material manufacturing top load, rev-happy engine bearing.Aluminium bronze has been widely used in military and civilian industry.Early stage aluminium bronze adopts integral cast to make the parts such as bearing, axle sleeve, friction block, and not only consume a large amount of non-ferrous metals, and be single-piece production, efficiency is very low.Afterwards, due to the development of bimetallic material, occurred aluminium bronze to cast in technique steel backing making bimetallic bearing, non-ferrous metal consumption greatly reduces.But still do not break away from the restriction of single-piece production, yield rate is not high, and production efficiency is low, cannot realize large-scale industrial production, and the application of this up-and-coming bearing material is restricted.
In order to overcome the problems referred to above, the present invention designs a kind of new technology of producing aluminum bronze-steel dual-metal bearing material, design is optimized to bimetal bearing material chemical constituent, produce aluminum bronze-steel dual-metal material by the method for solid phase compound, utilize sheet copper as intermediate layer to improve adhesion strength.This technique has a lot of superiority, as can continuous high-efficient rate batch production, finished product rate is high, dimensional accuracy is high, alloy allowance is few, production cost is low, has wide market prospects.
Summary of the invention
Object of the present invention is exactly the defect existed for prior art, invents a kind of new technology of producing aluminum bronze-steel dual-metal bearing material.Its technical scheme is a kind of new technology of producing aluminum bronze-steel dual-metal bearing material, it is characterized in that: the chemical composition of novel aluminum bronze: Al 7.4%+Fe 3%+ Mn 0.2%+ Ni 0.5%, Cu is surplus.Adopt the method for solid phase compound to produce aluminum bronze-steel dual-metal material, utilize sheet copper as intermediate layer to improve adhesion strength.
The optimization of smelting technology, have selected graphite powder+borax as coverture, and ice crystal+sodium carbonate is as refining agent, and Ti-B series, as alterant, uses the Be very effective of after-purification solution, crystal grain thinning.Adopt water cooled mo(u)ld cast, strict degree of supercooling, the intensity of cooling controlling alloy simultaneously.Alloy plasticity has been excavated in these measures to greatest extent, also improves the quality of alloy simultaneously.
Master operation: be first smelting aluminum bronze, by controlling the content of aluminium, add the elements such as Fe, Ni, Mn in proportion, obtaining required composition and correlated performance, i.e. novel aluminum bronze.Next is rolling and heat treatment, is again to carry out aluminium bronze and sheet copper composite rolling, and this is one of critical process of this technique.Then anneal, after annealing, carry out finish rolling, improve the binding strength of sheet copper and alloy further.Subsequently steel plate and aluminium bronze-red copper alloy sheets are carried out multiple rolling, adhesion strength Rch is greater than 120N/mm
2, obtain satisfactory gross thickness and alloy layer thickness.Finally anneal, steel plate and alloy-layer are bondd firmly.
Feature of the present invention is: aluminum bronze-steel dual-metal bearing material technique has a lot of superiority, as can continuous high-efficient rate batch production, finished product rate is high, dimensional accuracy is high, alloy allowance is few, production cost is low; Comprehensive mechanical property, wear resistance and corrosion resistance, bearing capacity and fatigue resistance are high, are a kind of first-class bearing materials.Avoid expensive tin and poisonous lead in alloy, this saves scarce resource with national, the policy of protection of the environment is consistent.Along with internal combustion engine is constantly to high rotating speed, high supercharging pressure level future development, can foretell, new technology will make aluminum bronze-steel dual-metal bearing material move towards the industrialization, and become from now on for one of the main flow bearing material of top load, rev-happy engine, have wide market prospects.
