Discussion on Security Early Warning Mechanism of BF Hearth

摘要：

　　Recently lots of blast furnaces (BFs) face the problem of hearth severe erosion even burnt out accidents.The campaign life of hearth has become the limiting factor for safe and high efficiency production of modern BFs.However,the early warning mechanism of hearth has not been clear due to the lack of system research.In this article,based on the heat transfer calculations,heat load and erosion monitoring for various BF hearths with different volume,structure and refractory,the features of heat load and erosion for different kind hearth are compared and analyzed.The primary detecting elements,software models,evaluating standards and warning methods are discussed.The early warning mechanism of modern BF hearth is proposed.
