■ Casting process
The main shaft of crusher for large-scale ingot casting process is produced by EAF primary smelting → LF refining → VCD vacuum treatment  →VC vacuum pouring ingot → Forging.
■ Forging process
Pressure clamp→ Pre-drawing →Upsetting, drawing →Rolling → Drawing to finished products.
■ Performance heat treatment process
Normalizing→ Tempering→ Air cooling out of furnace→ Dimension and hardness testing of each part→ Taking performance test rods.
