The damage modes of elbow pipe bricks include mechanical scouring of molten steel, slag erosion and thermal shock caused by temperature gradient. Through the disassembly and analysis of teapot steel-clad pipe bricks and elbow bricks after use, it is found that the elbow bricks are the most seriously damaged. Usually, the teapot ladle is offline because of severe scouring and erosion of the elbow bricks, and the scouring and erosion of the tube bricks are relatively light.
