摘要

High-temperature spot, air leakage, and even burn out accidents occurred frequently in bellows of hot blast systems in the metallurgy industry, which seriously affected the stability of the hot blast system and brought hidden danger to safety production. Although coating, grouting, and other treatment measures had been adopted, the effect was very little. Through dissecting and sampling analysis of the failure bellows, it was concluded that the steel structure of the bellows had cracking hidden danger due to welding quality defects, and other reasons for the failure were high temperature of the bellows steel structure caused by hot air channeling. Therefore, it was proposed that not only the steel structure material and design but also the performance and quality of the internal refractory material of the masonry should be paid attention so as to ensure the air tightness. Only by combining these two aspects can the service life of bellows be effectively improved.
