摘要

In recent years, Chinese steel companies suffered a spate of blast furnace hearth incidents, such as hearth sidewall breakout or temperature abnormal increase, causing Chinese blast furnace ironmakers to pay a great deal attention on long hearth service life technology. In this paper, the progress of Chinese blast furnace long hearth service life design concept was analyzed deeply from design of hearth structure, selection of hearth refractory, arrangement of hearth cooling system and establishment of online hearth monitoring system, and the future design proposal for long hearth service life of Chinese blast furnace was put forward.
