The security and stability operation of stave is the basis for a long-life operation of a BF. A good cooling system and process conditions, especially in the high heat load area of the waist and the bosh, can form a stable slag on the surface of stave, which can protect the stave and prolong the service life of BF. In recent years, domestic and foreign scholars have studied the heat transfer characteristics and slagging capacity of the copper stave thermal structure in the bosh region from the perspective of heat transfer.1–6) Y. Zhong et al.7) conducted a systematic feasibility analysis on the buried pure copper tubular cast copper stave. G. S. Guo et al.8) studied the heat transfer effect of cooling specific surface area on the stave based on the finite element method. S. Lin et al.9) conducted a thermal test on a buried copper tubular stave, and concluded that the gas temperature has a significant effect on the stress distribution of the copper stave body. Y. Deng et al.10) discussed the fracture mechanism of the rolled copper stave pipe and proposed a repairing method, K. Kawaoka et al.11) conducted a high Optimization Analysis of Mechanical Performance of Copper Stave with Special-shaped Tubes in the Blast Furnace Bosh
