Forged Ball Production Line
1) Traditional Forged
Raw material →Cutting →Heating → Water quenching → Tempering
2) Auto Hot Rolling
Raw material →Hot Rolling Mill → Water Quenching → Tempering
Cast Ball Production Line
Raw material chemical composition and optional proportion→ Melting and pouring
→ Oil quenching→Temper→Polishing
Packing
1000kgs in a bag or 850-900kgs in a steel drum, then 25 tons in a
20GP Container
