Pulley Processing Treatment and Inspection Requirements

    Roller Processing Heat Treatment and Inspection Requirements: 1. Heat Treatment of Welded Cylinder Skin: Place in a benchtop oven and heat to 550-560 degrees (heat to 550 degrees at room temperature for 4 hours, place at 550-560 degrees for 4 hours, cool naturally to room temperature for 4 hours). Heat treatment during roller processing is mainly to improve material properties, such as making the surface harder and more wear-resistant through quenching, making the core tougher through tempering, and also eliminating internal stress generated during processing to stabilize dimensions. These treatments can extend the roller's lifespan several times and make it more reliable during high-speed operation. 2. Inspection: The weld joint between the connecting plate and roller needs to undergo non-destructive flaw detection (ultrasonic flaw detection, magnetic particle flaw detection)

   Testing instruments: Ultrasonic Flaw Detector, Magnetic Particle Flaw Detector

   Roller shaft heat treatment: 1. Roller shaft quenching treatment (tempering treatment) mainly enhances performance through "quenching + high-temperature tempering." Simply put, quenching makes the shaft hard, while high-temperature tempering makes it less brittle. This way, it can withstand heavy loads without easily breaking. It can also eliminate internal stresses generated during processing, preventing deformation or cracking. 2. Non-destructive flaw detection and hardness testing.
