[Case Study] Noise Prevention Measures During H-Beam Inversion - Noise Control Measures in Product Inspection Factory

Noise prevention measures during the inversion of H-shaped steel and noise control measures at the product inspection factory.

At the H-beam factory of A Steel Works, products (H-beams) are inspected for defects while rotating on rail steel. This inspection process is conducted continuously 24 hours a day, and the H-beams being inspected range from small ones measuring 244w×252h×11m and weighing 0.7t, to larger ones measuring 890w×299h×15.5m and weighing 3.3t. The noise level in this factory was tremendous. The noise exceeded 120dB, which is quite loud, and in this working environment, even with earplugs, there is a risk of hearing loss, leading to a request for consultation on noise prevention measures. 1. The noise during the flipping of H-beams is severe. 2. There is constant noise 24 hours a day due to multiple inspection lines. 3. Even with earplugs, it can lead to occupational hazards for workers (such as hearing loss). 4. Despite inspecting for defects, there were instances where beams were damaged due to falls.
