| JSW Steel Ltd. is the youngest Greenfield integrated steel plant located in the economic backwaters of the state of Karnataka in the district of Bellary. It is a part of the US $2.0 billion JSW conglomerate. It is the first steel plant in India and the third in the world to have the Corex Technology for iron making. This project pertains to refractory lining of the converter, used to convert hot metal into steel. These linings are very expensive material and are the major contributors to the cost of steel making process. There are several factors contributing to the chemical and physical erosion of converter refractory linings. Using quality tools such as Flow Diagrams, Brainstorming, Cause and Effect Diagrams and Hypothesis Testing, the team discovered that the most significant factor affecting the life of converter refractory lining was slag splashing time. Armed with this knowledge, the team at JSW steel, achieved a breakthrough in slag splashing through statistical analysis and design of experiments to enhance the converter lining life and reduce refractory consumption. The developed slag model and optimized parameters has helped to increase the converter lining life to a national benchmark of 13771 heats which is more than 2.5 times of the highest lining life reported by any other steel plant (Bhilai Steel Plant - 4872 heats) in India. |
