EUROPEAN STEEL TECHNOLOGY AND APPLICATION DAYS 2017 - ESTAD 2017

Si bearing automotive steels manufactured from the Compact Strip Production (CSP) are used for making the surface critical Wheel & Rim application. A lot of scale issues are encountered in these grades making it very difficult to meet the urgent needs of the customer and it also leads to a lot of downgrading at Tata Steel’s premises. A cross functional project was undertaken at Tata Steel’s CSP to overcome this issue through a novel approach of fine tuning of the chemistry of the scale and process parameters optimization in the Finishing Mill of the CSP plant. Based on the successful outcome of these trials,the modified chemistry and the process parameters were incorporated in the Standard Operating Procedures. This paper showcases the journey which Tata Steel’s CSP embarked upon w.r.t. study of the process parameters and the implementation of the key learning associated with it.
