How to Inquire

When ordering balls, please specify the following:
1. Nominal ball diameter.
2. Type of material.
3. Precision grade.
All standard balls are always in stock and ready for immediate off-the-shelf delivery. If your application calls for custom balls, send us your specifications and we'll gladly meet them

 
Internal quality
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
1. Impact test:
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.
