Testing:
The steel ball quality inspection process mainly includes the
following steps: Appearance quality inspection: First, check the
surface quality of the steel ball to observe whether there are
obvious defects such as cracks, depressions, bubbles, etc. These
defects will affect the performance and life of the steel ball.
Size and weight detection: Use precise measuring instruments such
as calipers and micrometers to measure the diameter, roundness,
weight and other indicators of the steel ball and compare them with
the standard values. If there is a large deviation, it means that
there is a problem with the size and weight of the steel ball.
Hardness test: Use a hardness tester to measure the hardness value
of the steel ball to determine whether it meets the standard
requirements. The hardness value is related to factors such as
chemical composition and heat treatment process.
Chemical composition analysis: Use modern equipment such as
inductively coupled plasma optical emission spectrometer (ICP-OES)
to analyze the chemical composition of the steel ball to ensure
that its composition meets the prescribed chemical composition
standards.
Metallurgical structure analysis: Use optical microscopes and other
equipment to observe the metallographic structure of the steel
ball, evaluate its organizational morphology, grain size, phase
distribution, etc., to understand its mechanical properties and
wear resistance.
Physical property test: Including tensile and bending tests to
evaluate whether the physical properties of the steel ball meet the
requirements. These test results are related to the wear
resistance, mechanical properties and vibration characteristics of
the steel ball.
Wear resistance test: Test the wear resistance of the steel ball
under actual use conditions to ensure its performance in long-term
use.
Fatigue test: Evaluate the service life of the steel ball under
repeated stress conditions to ensure its stability under high load.
