Abstract

For more than 40 years, HYL has developed technologies designed to improve Hylsa's steelmaking competitiveness and productivity. The HYL direct reduction technology, while perhaps the best known, is accompanied by other technologies designed for making steel in more efficient, cost-effective ways. The HYL Process has been improved over generations, and the current status of the technology, the HYL Self-reforming Process, was developed to allow reduction of iron ores in a shaft reactor without external gas reforming equipment. The HYTEMP System, developed to transport hot, high carbon DRI directly to the EAF melt shop, has been successfully implemented. Additional technologies related to steel production have been developed and implemented, such as improvements in hot rolled strip production to allow for ultra-thin gauge HRC, Hylsa's Multiple Slit Rolling technology for bar mills, and the HYL HY-Recovery Process for recuperation of iron units and heavy metals from steel mill waste. All of these technologies, in addition to training and technical assistance programs in all aspects of iron and steelmaking, are detailed in this paper.
