SUMMARY:Blast furnace hearth refractory lining management
DESCRIPTION:For the most part, blast furnaces' campaign life relies on the condition of their hearth refractory lining.    The hearth refractory lining mainly consists of carbon, micropores, graphite, and ceramic caps or some combination of two or three of these mentioned brick types.  Blast furnace lining undergoes severe thermal-mechanical and thermal-chemical abuses that result in its wear and deterioration. Aside from direct hot metal wear, penetration and percolation of gasses within the lining, particularly the walls, affect the lining by causing chemical instability and failure of its material properties.  

In other words, the integrity of the blast furnace refractory systems is critical to its continuous operation. Hence, a comprehensive, multisource, risk-based, and dynamic management program is required to ensure that no sudden failures interrupt the operation.  The hearth being the critical section of the furnace, its refractory thickness and quality must always be known.  This information requires reliable and steady data sources acquired during furnace operation.  The primary data is provided by various non-destructive testing (NDT) inspection and monitoring techniques, which do not interrupt furnace operation. The secondary data is provided by furnace operation and controls, such as the coke, pellet/sinter, flux quality and chemistry, all the output gases, chemistry, and temperatures.   An integrated risk-based refractory management system is designed to reduce the probability of lining failure and increase the furnace campaign life.
