The production of the bowl assembly integrates advanced materials science and precision manufacturing technologies to ensure extreme durability, dimensional accuracy, and structural reliability as the core component of a cone crusher.
The key process flow is as follows:
1.Stringent Casting Process:Selected high-strength alloy steel is used to ensure the base material possesses excellent impact resistance and wear performance.Casting simulation software is employed to digitally simulate and optimize the pouring, cooling, and solidification processes.
2.Precision Heat Treatment:The rough casting undergoes a combined normalizing and tempering heat treatment. This process refines the grain structure, eliminates internal casting stresses, and uniformly enhances the hardness, toughness, and fatigue resistance of the material.
3.High-Precision CNC Machining:Critical mating surfaces—such as the threads that engage with the adjustment ring and the register (spigot) that fits with the main frame—are precision-machined using large CNC boring and milling machines.
4.Comprehensive Non-Destructive Testing (NDT)
The finished Bowl Assembly body undergoes a rigorous multi-layered NDT inspection system:OPI (Oil Penetrant Inspection): Detects minute surface cracks or flaws.UT (Ultrasonic Testing): Examines the internal structure for voids, inclusions, or delaminations.MPI (Magnetic Particle Inspection): Identifies surface and near-surface defects, especially crucial for ferromagnetic materials.
