SUMMARY:Life enhancement and design improvement of basic oxygen furnace
DESCRIPTION:An integrated steel plant including two Basic Oxygen Furnaces (BOFs) in one melt shop identified the need and opportunity to enhance the refractory campaign life and furnace shell life of the BOFs.

Hatch worked with the steel plant to understand the mechanisms that influence the lifespan of refractory and vessel shell campaign lives, including review of refractory material selection and thermomechanical evaluation. Based on the findings from this study, various options for enhancing the life of the converter were evaluated. These included options for increasing the life of a replacement converter vessel such as improved cooling systems, altering the refractory system to reduce shell heat loads, and a new material of construction. Changes to the refractory material selection and operational practice to improve lining performance were also investigated.

The enhanced refractory design and equipment improvements implemented by the steel plant has allowed an optimized converter operation with an extended refractory campaign life. This optimization also lead to a reduction in shell temperatures, which will result in longer vessel campaign life. This has led to improved productivity, with key recommendations from the study also being applied to other BOFs at the plant.
