SUMMARY:Operational flexibility for the blast furnace using the sequence impulse process (SIP)
DESCRIPTION:"When operating a blast furnace, the ability to positively influence raceway characteristics and improve the permeability of the process, are key features that can enhance performance. The Sequence Impulse Process (SIP) is an oxygen pulsing technology credited with providing a way for blast furnaces to realise such benefits, at scale, today.
This paper explains the technology and provides operational feedback from Schwelgern BF1, Germany operated by thyssenkrupp Steel AG. It discusses how regular injection of high energy SIP oxygen, has enabled a shift in operational outcomes. The total reducing agent rate and the carbon footprint have been lowered, as have heat loads to the tuyeres and shaft areas of the blast furnace. These compounded changes lead to significantly reduced OPEX and a rapid return on investment for the plant. Through the use of SIP, the performance improvements have been experienced even during periods of reduced burden material quality and have realised greatly enhanced stability characteristics in the blast furnace when compared to conventional operation. Raceway material analysis reveals improved conditions for metal/slag removal providing a mechanism for better drainage such that production level increases could also be considered.
In utilising SIP, blast furnace operators now have a tool that provides flexibility to shift their operational drivers between gas utilisation, productivity and material use according to the requirements dictated by a multitude of influencing factors,"
