AI Technical Summary
⚠Technical Problem
After prolonged use, the lifting lugs of existing electric arc furnace covers may become loose and insecure, posing a safety hazard and resulting in significant cooling water consumption.
⚗Method used
An energy-saving furnace cover for electric arc furnaces was designed, which adopts a water circulation cooling system and a blower mechanism. Cold air is introduced into the cooling water in the water tank through an L-shaped pipe and a concentrator, reducing cooling water consumption. The lifting lugs are prevented from loosening by a detachable U-shaped hanger and a locking mechanism.
🎯Benefits of technology
This achieves energy-saving use of cooling water and improves safety when replacing the furnace cover, avoiding safety hazards caused by loose lifting lugs.
