Grinding media ball
According to the national standard GB8649-88 & forging (rolling) ball ferrous metallurgy industry standards (YB/T 091-2005), our plant specializes in producing forged/casted grinding media ball diameter from Φ20- Φ130mm.
The advance manufacturing methods and materials guarantee the maintenance of the geometrical tolerance and correct structures vital to reliable, consistent performance and long life.Therefore, our grinding balls are of rounded geometry, high hardness and good mechanical properties and resistant to wear, no distortion, no cracking of excellent quality.
|2).High hardness Good wear resistant|
Our products are all kinds of ferrous and nonferrous metals mine concentrator, power plants, cement plants, refractory plants and other industries has been widely used by domestic and international customers alike.
|It is not allowed that crack, obvious porosity, slag inclusion, shrinkage, cold insulation, wrinkled skin and other casting defects exist on the section which goes through center of gate and sphere.|
|Test Method and Rules|
Cutting 10mm×10mm×55mm part through gate in ball as sample
|2.Rockwell hardness specimen preparation:|
The surface of the ball takes the test after grinding to platform, and the grinded thickness is 1.5 - 5mm.
|3.Chemical composition test:|
When the volume smelting furnace more than 0.5 tons,we should check the chemical composition furnace by furnace;
When the volume smelting furnace not more than 0.5 tons, we should check the chemical composition once per shift.
Once there is one furnace unqualified, we need to sample double furnace for test.
If there is still one not qualified, this branch of balls is unqualified.
|4.Surface hardness test:|
Sampling from different location of each batch of heating furnace, the number of the ball≥ 5.Once there is one unqualified, we need to sample double balls for test.If there is still a ball not qualified, this branch of balls is unqualified.
|5.Internal quality detection:|
We sample 1 largest size casting iron grinding ball in 100 tons the same type cast iron grinding ball of each continuous production.
Once there is one unqualified, we need to sample double balls for test.
If there is still a ball not qualified, this branch of balls is unqualified.
STRICT PRODUCTION PROCESS
A.Raw material--Wire drawing--Cold heading--Flashing--Heat treatment--Grinding--Lapping 1--Lapping2--Lapping3--Washing--Checking.
All balls must be passed the procedure of passivity.Each procedure have professional inspector.They will check steel balls each two hours to insure the correction diameter and good surface of SAIGE steel ball.
B.Our high precision bearing steel balls is G10.(Diameter variation is in 0.25um)
Following is our inspection standard of G10 steel balls:
1.Each size of chrome steel balls have their own standard balls which are imported from Japan.
2.These standard balls were stocked into antitrust oil at the temperature 20° C.
3.Our size measurement instrument's precision is up to 0.1um.Also import from Japan.
4.We will check the diameter, hardness, surface, deviation from spherical, vibration value and so on.
