The MURC Process

The research identifies several advancements in the Multi-Refining Converter (MURC) process aimed at reducing costs and minimizing slag generation during high-grade steel production. The primary objective was to optimize the four key steel refining processes—desiliconization, desulfurization, dephosphorization, and decarburization—while ensuring high operational efficiency and compliance with environmental standards. Methodologically, the study conducted a thorough review of historical hot metal pretreatment methods and implemented innovative strategies to separate these critical refining processes. Results demonstrated that the new approach significantly enhanced reaction efficiency, facilitated increased slag recycling, and reduced lime consumption by 40%. Additionally, the process's design allows for broader flexibility in raw materials selection and greater thermal tolerance in reaction vessels. The findings underline that the optimal coordination between the converter’s surplus capacity and the refining stages can lead to substantial improvements in productivity and sustainability of steel manufacturing. This study not only presents a roadmap for enhanced steel production techniques but also contributes to the ongoing discourse on environmental standards in industrial processes.
