Description
Hot rolled steel ball is a new technology, that is a breakthrough technology in manufacturing ball milling . Casting ball is gradually replaced by hot-rolled steel ball.
Hot-rolled steel ball has characteristics as follows.
1.Hot-rolled steel Ball has all the advantages of steel ,
it become high-quality milling ball by heat treatment.
2.High production efficiency,
large output,
mechanized production of steel ball,
high degree of automation,
no manually operated production process,
less labour and less disturbance by human factors.
3. Stable quality,
high hardness good hardenability,
dense microstructure,
small grain size,
no deformation from beginning to end ,
no losing circle, good wear resistance.
4.Low energy consumption,
no pollution, low labor intensity,
lower production costs.
5.Good shape,
small geometric tolerances,
stable quality.
6.Low wear rate,
long using life, is 2~5 times than the existing cast iron ball,
forged steel ball,
and the price is quite.
7.Ball hardness is up to *0 ~ *7HRC.Internal and external hardness are balanced,
hardness difference is less than 5HRC.
8.High impact toughness is more than *2J/cm2.
