The Berry Metal Company has effectively commissioned its newly developed lime injection package for Arkansas-based EAF steel producer, Big River Steel (BRS).
The system’s scope involved planning and furnishing a wide-ranging technology compilation for pneumatic lime injection at BRS’s greenfield plant in Osceola.
The platform was originally commissioned and installed in May 2020 during the first phase of the steelmaker’s electric arc furnace (EAF). The metal company has also been appointed to set up a comparable structure for the finalization of BRS’s second phase EAF next year.
The tailor-made structure attained a flow rate of 1,000lb per minute for dolomitic and high-calcium lime—considered to be among the highest levels in North America, according to a statement from Berry.
The new technology offers significant advantages, like allocating proper flow of several grades and sizes of lime fragments without obstruction. The lime injection is also delivered quickly into the hot metal, thereby increasing production during the steelmaking process.
Operations at the mill continued while the system was fitted, ensuring that standard steel production levels weren’t compromised. The lime system enables efficient control of the lime blend so that BRS workers have the ability to enhance raw material usage during the melting process, said David Werner, president of Berry Metal.
The structure containing the EAF lime injectors is intended to expand BRS’s ability to manage slag characteristics and benefit the entire steel process, the news release also stated.
Berry provides for the steel industry by taking on chemical energy, lime injection, carbon injection, ladle and tundish preheaters, repairs, engineering, and more for the furnace and casting areas of the steelmakers’ EAFs.
