AI Technical Summary
In existing impact protection structures for molten iron ladles, the joints of the refractory bricks are exposed to the impact range of molten iron, causing the impact protection mechanism to crack or loosen prematurely, resulting in poor durability.
The bottom layer of the tank is connected to the reinforcing block by a snap-fit structure. The snap-fit groove and snap-fit block of the reinforcing block, combined with the tenon and groove design of the refractory brick, enhance the connection strength. A buffer zone and castable hoop are set at the connection between the working layer and the tank body to reduce vibration and wear.
It effectively reduces the direct impact of refractory brick joints, extends the service life of the molten iron ladle, and improves the durability of the impact-resistant structure.
