Description

Technical Field

[0001] The utility model belongs to the technical field of torpedo tank lining bricks, in particular to a torpedo tank working lining brick with a long service life. Background Art

[0002] Torpedo tanks are large-scale molten iron transportation equipment, named for their long horizontal length and torpedo-like shape. They are mainly used to hold and transport molten iron produced by blast furnaces, and have the characteristics of large capacity, good thermal insulation performance, low center of gravity, and high safety. Torpedo tanks play the role of connection, matching, coordination, and buffering in the ironmaking and steelmaking processes. They can store molten iron to coordinate the temporary imbalance of ironmaking and steelmaking.

[0003] Lining bricks need to be installed inside the torpedo tank to isolate heat and prevent molten iron from damaging the torpedo tank body. However, since the inner wall of the torpedo tank is curved, the curved lining bricks fit the inner wall of the torpedo tank and multiple lining bricks are interlocked with each other. When the lining bricks are damaged, they need to be replaced, which is cumbersome and easy to damage the undamaged lining bricks. Utility Model Content
