1) Description of Copper Bushing
Copper bushings are tubular components made of copper alloys formed
through metallurgical processes.
They are produced via casting, forging, or machining, with common
alloying elements including tin, aluminum,
and zinc. During the manufacturing process, strict control is
exercised over the composition ratio and microstructure,
endowing the products with specific mechanical properties. They are
indispensable basic components
in the field of mechanical manufacturing.
2) Feature and Advantage of Copper Bushing
a) Highly Adjustable Composition: The composition ratio of copper
alloys can be flexibly adjusted according to
different application requirements. For example, increasing the tin
content can enhance wear resistance,
while adding aluminum can improve corrosion resistance, meeting
diverse industrial application scenarios.
b) Diverse Forming Processes: Various processes such as centrifugal
casting and sand casting can be employed,
catering to different precision and production volume requirements.
Centrifugal casting can produce copper bushings
with a dense microstructure and excellent performance, while sand
casting is more suitable for small - batch production
of customized, complex - shaped components.
c) Controllable Cost: Compared with components made of some rare
metals, copper alloys are sourced widely,
and the production processes are mature. This enables effective
cost control while ensuring performance.
3) Working Principle of Copper Bushing
In metallurgical manufacturing, copper bushings function based on
their internal microstructure.
The hard phases in the alloy provide wear resistance, while the
soft phases offer lubrication. When paired with a shaft,
a microscopic lubricating layer forms on the surface of the copper
bushing during friction, reducing the coefficient of friction.
Additionally, it can adapt to slight shaft eccentricity and
vibrations through its plastic deformation.
4) Application of Copper Bushing
In the metallurgical industry itself, copper bushings are used in
equipment such as blast furnace burden distributors
and continuous casting machine roller tables. In the field of
mining machinery, they are applied in components
like the eccentric shaft bushings of crushers and the hollow shaft
bushings of ball mills. In these scenarios,
equipment operates under heavy loads and harsh environments. Copper
bushings ensure stable equipment operation
with their customizable performance.
