1. Raw material: All the material is qualified with certificate and made in the Chinese largest steel production enterprise.
2. Customize products according to the clients's requirements.
3. Cutting: At first, the steel bars should be cut into small pieces according to the size of steel balls we want.
4. Heating: we use the electric furnace instead of the traditional coal stove, the biggest advantage is that all the steel bars can accept the most approriate temperature during the heating progress. It affect the hardness and toughness directly.
5. Hammer forging: The raw material is forged to a certain deformation by the air hammer, when the compression ratio increased, the micro-structure become more compact so that the hardness and the toughness can be improved.
6. Heat treatment: Both the water quenching heat treatment production line and our own temperature control technics are important. We have very mature production technicians responsible for the heat treatment process as we know this process affect the grinding balls performance directly.
7. Quality test: we have professional testing equipments in our factory, and it's convinient to do the quality test every shift. At the same time, we have the ISO9001:2008 and SGS certificate.
8. Packing: it depends on the clients' requirements.
Container bags or steel drums or others.
