Abstract
The invention provides a cast iron material for an aluminum piston wear resistant insert ring. The cast iron material comprises the following components in percentage by mass: 2.2-2.8% of carbon, 2.0-2.5% of silicon, 0.8-1.5% of manganese, 1.0-1.5% of chrome, 13-15.5% of nickel, 5-7% of copper, phosphorus not greater than 0.06%, sulfur not greater than 0.05%, lead not greater than 0.005%, tin not greater than 0.05%, zinc not greater than 0.05%, arsenic not greater than 0.05%, and the balance of iron. Compared with an existing wear resistant insert ring cast iron material, the cast iron material for the aluminum piston wear resistant insert ring has the advantages of better wear resistance, more stable hardness, better processing performance, more reasonable elongation and tensile strength range and large improvement of use effect.
Description
Technical field
The invention provides a kind of cast iron materials, especially a kind of cast iron alloy material for aluminum piston abrasion-proof inserted ring.
Background technology
Piston is a main parts size that affects service life of aeroengine, it works for a long time under high degree of mechanical load and thermal load, its first, second annular groove are again the weak links of piston result, easily abrasion deformation occur and shorten maintenance mileage and the work-ing life of engine.Therefore first, the second ring band at piston used the austenitic iron ring of corrosion-resistant and high-temperature resistant to solve, and this cast iron ring is again aluminum piston durable inlaid ring.Its Working environment requires this material will have good wear resistance, and thermal expansivity is close with piston aluminium alloy body, has good binding property with piston aluminium alloy.Current cast iron alloy material is difficult to meet completely above-mentioned requirements, and result of use is poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cast iron materials for aluminum piston abrasion-proof inserted ring, to improve its result of use.
The present invention is achieved in that a kind of cast iron materials for aluminum piston abrasion-proof inserted ring, it is characterized in that, by mass percentage, the component of described material is, carbon, 2.2%～2.8 %; Silicon, 2.0%～2.5%; Manganese, 0.8%～1.5%; Chromium, 1.0%～1.5%; Nickel, 13%～15.5%; Copper, 5%～7%; Phosphorus ,≤0.06%; Sulphur ,≤0.05%, lead ,≤0.005%; Tin ,≤0.05%; Zinc ,≤0.05%; Arsenic ,≤0.05%; Surplus is iron.
This cast iron materials for aluminum piston abrasion-proof inserted ring, compares with existing abrasion-proof inserted ring cast iron materials, and wear resistance is better, hardness is more stable, processing characteristics is better, and the scope of thermal expansivity, unit elongation and tensile strength is more tending towards rationally, greatly having improved result of use.
Embodiment
Further illustrate the present invention below.
Production method for the manufacture of the cast iron materials of aluminum piston abrasion-proof inserted ring is: the pig iron, foundry returns, steel scrap, electrolytic manganese, electrolytic nickel, ferrosilicon, ferrochrome, electrolytic copper and carburelant are carried out to stokehold batching by the component content requirement of abrasion-proof inserted ring cast iron materials element, adopt middle frequency furnace to carry out melting, add successively in order various melting materials, by its melting to 1400-1550 ℃, then the chemical composition of abrasion-proof inserted ring liquation is chemically examined, and adjusted each raw-material consumption according to result of laboratory test.Chemical composition detected result meets after material composition requirement, starts to utilize liquation to cast, and in casting forward direction liquation, adds nucleating agent.Add after nucleating agent, though the content of silicon slightly raises in cast iron composition, should still be controlled in component content requirement, on other composition without impact.The liquation that has added nucleating agent is poured in the casting mould of high speed rotating, carry out rotary casting, cast out the blank of abrasion-proof inserted ring, the physicalies such as metallographic to blank detect, detect qualified after, abrasion-proof inserted ring blank, through a series of processing process, is processed into abrasion-proof inserted ring finished product.
The matrix of the present invention's cast iron alloy is austenite structure, contains 2-10% equally distributed tiny alloy carbide.In its metallographic structure, graphite is mainly A type, Type B and a small amount of D type, E type, and the total amount of D type, E type graphite is no more than 40%.These indexs can be by controlling the incubation time of molten metal, the add-on of nucleating agent and control speed of cooling etc. and realize.This is apparent for those skilled in the art, no longer describes in detail.
The composition such as sulphur, phosphorus is inevitable impurity in alloy production process, and its content is more few better.
The method of the abrasion-proof inserted ring castingin that the present invention's cast iron materials is made on aluminium piston is: first distinguish preheating piston blank mold and Xiang Quan, again abrasion-proof inserted ring is immersed in the molten aluminium alloy in molten bath and carry out aluminising, then abrasion-proof inserted ring is put to the position of imbedding mould abrasion-proof inserted ring, to cast aluminum liquid in mould, then carry out die cast, make the piston blank that castingin has abrasion-proof inserted ring.
Practical application shows, the bond quality of the abrasion-proof inserted ring that the present invention's cast iron materials is made and aluminium piston body meets Its Relevant Technology Standards.
Table 1 be the abrasion-proof inserted ring (being called for short Ni-based edge circle) made of the present invention's cast iron materials with existing standard (JB/T9762) in the contrast (by mass percentage and iron be surplus) of main alloying constituent of Ni-based austenite cast iron alloy edge circle (abbreviation standard edge circle).
Table 1
Table 2 are abrasion-proof inserted rings (being called for short Ni-based edge circle) of making of the present invention's cast iron materials with existing standard (JB/T9762) in the contrast of main using property data of Ni-based austenite cast iron alloy edge circle (abbreviation standard edge circle).
Table 2
From above two tables, can find out, the abrasion-proof inserted ring that the present invention's cast iron materials is made is compared with standard edge circle, each index is better than standard edge circle, compare with standard edge circle, in the abrasion-proof inserted ring that the present invention's cast iron materials is made, the content of nickel, copper reduces more than 10%, the content of chromium reduces more than 40%, thereby has reduced production cost, improves product competitiveness.The thermal expansivity of thermal expansivity and aluminium piston body is more approaching, is better than standard edge circle, and wear resistance and processibility are also better.
