Abstract
The invention discloses a kind of wear resistant alloy material, specifically a kind of Wear-resistant, high-temperature resistant nickel-base alloy axle sleeve processing method.The alloying component of its raw material weight percentage are as follows: nickel 53~66%, chromium 20~25%, copper 3~5.8%, holmium 0.05~0.15%, manganese 10~12%, titanium 0.25~0.35%, cobalt 0.4~0.6%, surplus are rare earth.Since axle sleeve of the invention increases with the chromium and copper being added in nickel-base alloy the tensile strength and hardness of alloy, what is be added increases the hardness and toughness of alloy suddenly, holmium can be improved the corrosion resistance of alloy, the addition of cobalt increases the Hard Inclusion of alloy, substantially increase wearability, titanium can refine crystal grain, improve the obdurability of alloy, especially adding a large amount of rare earth element keeps its quality higher, from there through having selected suitable material extremely proportion relation, thus the axle sleeve produced has good hardness, intensity and toughness, good mechanical performance can be reached, long service life, with better economy and comprehensive mechanical performance.
Description
Technical field
The present invention relates to a kind of wear resistant alloy material, specifically a kind of Wear-resistant, high-temperature resistant nickel-base alloy axle sleeve processing side
Method.
Background technique
For axle sleeve as component important in the vulcanizer of tire production, it is used to the load in support shaft, it is desirable that has height
The wearability of intensity, the axle sleeve in the vulcanizer of existing tire production use diversified alloy material, although have
Can intensity with higher, its rigidity is poor, is easily damaged, although the rigidity having is relatively good, but wear no resistance,
Therefore it needs often to replace axle sleeve, therefore these existing axle sleeves are difficult to perfectly apply the vulcanizer in tire production
In, occur the axle sleeve using nickel-base alloy in the market later, but since its manufacturing method is unreasonable, however it remains it is numerous
Flaw.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Wear-resistant, high-temperature resistant nickel-base alloy axle sleeve processing methods.
In order to solve the above-mentioned technical problem, vulcanizer axle sleeve nickel-base alloy of the invention, the conjunction of raw material weight percentage
Golden ingredient are as follows: nickel 53~66%, chromium 20~25%, copper 3~5.8%, holmium 0.05~0.15%, manganese 10~12%, titanium 0.25~
0.35%, cobalt 0.4~0.6%, surplus is rare earth.
The alloying component of the optimum weight percentage of the raw material are as follows: nickel 58%, chromium 23%, copper 4.5%, holmium 0.08%,
Manganese 11%, titanium 0.3%, cobalt 0.5%, surplus are rare earth.
A kind of Wear-resistant, high-temperature resistant nickel-base alloy axle sleeve processing method, comprising the following steps:
A, melting:
Crucible is heated to 580~600 DEG C, nickel, chromium, copper, manganese, titanium, cobalt is sequentially added and is melted and is added
Holmium is added in rare earth after the completion of fusing, smelting temperature is controlled at 580~600 DEG C, and the degree of superheat is at 70 DEG C；
B, it is poured:
Melted ingredient is poured, pouring temperature is controlled at 580~600 DEG C, with sand mold moulding by casting；
C, it machines:
The blank of moulding by casting is machined out, is finished after first roughing.
Compared to the prior art, the invention has the following advantages:
Since axle sleeve of the invention increases with the chromium and copper being added in nickel-base alloy the tensile strength and hardness of alloy, add
What is entered increases the hardness and toughness of alloy suddenly, and holmium can be improved the corrosion resistance of alloy, and the addition of cobalt increases the hard of alloy
Particle substantially increases wearability, and titanium can refine crystal grain, improve the obdurability of alloy, especially adds a large amount of rare earth member
Element keeps its quality higher, and from there through suitable material extremely proportion relation has been selected, the axle sleeve thus produced has fine
Hardness, intensity and toughness, good mechanical performance can be reached, long service life has better economy and comprehensive mechanical
Performance.
Specific embodiment
With reference to embodiment, to a kind of Wear-resistant, high-temperature resistant nickel-base alloy axle sleeve processing method of the invention make into
One step is described in detail.
Embodiment one:
Vulcanizer axle sleeve nickel-base alloy of the invention, the alloying component of raw material weight percentage are as follows: nickel 52%, chromium
25%, copper 5.8%, holmium 0.15%, manganese 12%, titanium 0.35%, cobalt 0.6%, surplus is rare earth.
Embodiment two:
Vulcanizer axle sleeve nickel-base alloy of the invention, the alloying component of raw material weight percentage are as follows: nickel 58%, chromium
23%, copper 4.5%, holmium 0.08%, manganese 11%, titanium 0.3%, cobalt 0.5%, surplus is rare earth, it has been proved by practice that using this ingredient
It is more best in quality than the axle sleeve that manufactures, it is durable, extend 2 years as long as than common axle sleeve service life.
Embodiment three:
Vulcanizer axle sleeve nickel-base alloy of the invention, the alloying component of raw material weight percentage are as follows: nickel 65%, chromium
20%, copper 3%, holmium 0.05%, manganese 10%, titanium 0.25%, cobalt 0.4%, surplus is rare earth.
A kind of Wear-resistant, high-temperature resistant nickel-base alloy axle sleeve processing method, comprising the following steps:
A, melting:
Crucible is heated to 580~600 DEG C, nickel, chromium, copper, manganese, titanium, cobalt is sequentially added and is melted and is added
Holmium is added in rare earth after the completion of fusing, smelting temperature is controlled at 580~600 DEG C, and the degree of superheat is at 70 DEG C；Wherein, the addition of cobalt is not only
The mobile performance of nichrome is improved, and the effect of cobalt phase dissociated cracking and isolate matrix also improves the wear-resisting of alloy
Property, therefore improve whole wearability；The mechanical property that holmium element improves nichrome as reinforced phase is added, especially needs
It is increased in the present invention to be pointed out that there is a certain amount of rare earth element (rare earth usually added is between 1~5%) to close to nickel chromium triangle
The rotten of gold, microalloying and catharsis can refine nichrome crystal grain, more improve Wear Resistance, improve nickel
Evanohm high-temperature behavior；Certainly rare earth content is excessively high can also destroy overall performance, therefore its content highest is limited to 5%, preferably
It is 1%.
B, it is poured:
Melted ingredient is poured, pouring temperature is controlled at 580~600 DEG C, with sand mold moulding by casting；
C, it machines:
The blank of moulding by casting is machined out, is finished after first roughing.
