Abstract: Based on the vibrational parameters of trial runs on structure layer of coke house vibrating screen in 3000m³ blast furnace, the vibrational characteristics of structure layer were analyzed and studied. Reinforcement schemes were compared and chosen. The requirements and structure measures for anti vibration of structure layer were discussed.
