Production Process
1.Material Inspection
Custom the raw materials -- testing the chemical composition of raw materials by spectrometer -- Put the qualified steel material into workshop
2. Forging or Hot rolling
Put the raw materials into the intermediate frequency furnace and heat them to a certain temperature -- Hammer forged or hot rolled process -- cooling -- Quenching -- Insulation -- tempering
3. Quality Inspection
Testing the impact value -- testing the surface hardness -- cutting the steel ball by laser cutting machine --testing the core hardness -- Observe the metallographic structure by microscope -- testing the Steel ball fatigue life by drop tester
4. Packing and delivery
packing the qualified steel balls--Storage--Delivery from factory
Testing Equipment
We have a first-class laboratory and equipped with advanced testing equipment to ensure the quality:
Spectrometer--The wear resistance of steel grinding ball is mainly determined by its chemical composition.
Hardness tester-- Testing the surface hardness of grinding ball.
Laser cutting machine-- Cuting the core of grinding ball.
Impact tester-- Ball mill with a diameter more than 6m, the larger the impact value, the lower the breaking rate.
Microscope-- Observe the density and structure of steel grinding ball.
Drop tester--Testing the service life of the steel grinding ball.
