Technical Field

The invention belongs to the technical field of mechanical materials, and particularly relates to a babbitt metal wire and a preparation process of the babbitt metal wire.

Background

Babbitt metal is the most well known bearing material, tin-based and lead-based bearing alloys having anti-friction properties. The babbitt metal is mainly used for bearing bushes, bearings, bushings and shaft sleeves of large mechanical main shafts. However, the existing babbitt metal has the characteristic of poor flexibility, so that frequent breakage occurs during wire drawing, which causes great difficulty in making the babbitt metal into a wire shape, and therefore, aiming at the technical problem, the babbitt metal wire and the preparation process thereof are provided.

Disclosure of Invention

The invention aims to provide a babbitt metal wire and a preparation process thereof, and aims to solve the problems that the babbitt metal prepared by the existing process is poor in flexibility and strength and difficult to process into wires.

The invention is realized by the following technical scheme:

the invention relates to a Babbitt metal wire which comprises the following raw material components in percentage by mass: sb: 7% -18%; cu: 3 to 8 percent; au: 0.0001-0.005%; ni: 0.0001-0.01%; and the balance: sn, and trace elements of Cr, Mo and W.

Further, the babbitt metal wire is characterized by comprising the following raw material components in percentage by mass: sb: 8 percent; cu: 4 percent; au: 0.0001-0.005%; ni: 0.0001-0.01%; and the balance: sn, and trace elements of Cr, Mo and W.

The invention relates to a preparation process of a Babbitt metal wire, which comprises the following steps:

firstly, putting a copper material into an intermediate frequency furnace, stirring and smelting, then putting a tin material into the intermediate frequency furnace, stirring and smelting, adding an antimony material after the copper material and the tin material are melted, heating the furnace to 800-900 ℃, stirring, and adding hydrogen chloride to remove impurities;

-heating the furnace to 1400-1500 ℃, adding gold material and nickel-based superalloy containing nickel, molybdenum, tungsten and chromium and adjusting the element content;

cooling the furnace to 700-800 ℃, casting into a mold, and cooling to form a strip-shaped solid babbitt;

and sequentially carrying out reheating, extruding, drawing, annealing and wire drawing on the strip-shaped solid babbitt metal to prepare a babbitt metal wire.

Further, the stirring step is carried out by adopting electromagnetic stirring, and the stirring time is 5-15min each time.

Further, the reheating temperature of the strip-shaped solid babbitt alloy is 220-250 ℃, and the annealing temperature before the wire drawing step is 160-180 ℃.

The invention has the following beneficial effects:

according to the invention, the raw material component ratio of the Babbitt metal wire is adjusted, and the microelements are added, so that the finally smelted Babbitt metal is greatly improved in the aspects of flexibility and crystalline phase structure, the Babbitt metal is ensured not to be broken when being drawn into wires, and the flexibility and the strength of the Babbitt metal wire are improved.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
