AI Technical Summary
Existing converter slide plate slag-blocking mechanisms suffer from increased equipment failure rates, shortened service life, and reduced smelting efficiency and molten steel quality due to material oxidation, deformation, and wear in high-temperature environments.
The converter slide plate slag-blocking mechanism adopts an air-cooled system. By setting a cooling chamber and air inlet in the body of the clamping frame, cold air is introduced to cool down the structure, and springs and guide columns are used to improve the structural stability and adjustability.
It effectively reduced the equipment temperature, extended the service life of the slide plate, improved the mechanical strength and sealing of the equipment, and reduced maintenance costs.
