‘Know Your Level: Operational Benefits of Establishing Accurate Mold Level and Control’

Session: Mold Behavior Understanding (Continuous Casting)

Authors: Chason Ault, Steel Dynamics Inc. – Flat Roll Group; Skyler Brandt, Steel Dynamics Inc. – Flat Roll Group; Chuck Cappetta,
Steel Dynamics Inc. – Flat Roll Group; Andrew Spencer, Steel Dynamics Inc. – Flat Roll Group; Stephen deChaud, Vesuvius

Abstract: Investigation into irregular submerged-entry nozzle (SEN) erosion at Steel Dynamics Inc. – Flat Roll Group Butler’s thin-slab casters revealed a significant error in the caster mold level control systems. Upon correcting the error, numerous operational benefits have been realized. Accurate mold level control has allowed for the development of an optimized SEN wear program, which has increased average sequence length and reduced yield loss due to tundish skulls. Improved mold level control has also reduced the occurrence of sticker breakouts, decreased the number of slab downgrades for longitudinal cracks and allowed for increased casting speeds on some grades.

‘Comparison of Inclusion Modification Process in Lab Experiments and Industrial Production
After Reduction of Slags and Refractories by High-Al Steel’

Session: RE Enhancement, Hot Isostatic Processing & Bearing Fatigue Life (Metallurgy - Processing, Products and Applications)

Authors: Haoyuan Mu, Vesuvius; Bryan Webler, Carnegie Mellon University; Richard Fruehan, Carnegie Mellon University

Abstract: Dissolved high Al content in steel is able to reduce slag and refractory materials. As a result, corresponding metallic elements such as Mg and Ca are introduced into liquid steel and subsequently change original inclusions. However, the inclusion observation in lab experiments and industrial production is different to a certain extent. This project focuses on the kinetics of such inclusion modification reactions and provides modeling results to explain how different mass transfer conditions in lab and industry can alter the process of inclusion modification.

‘Optimized Steel Grade Transition Practice at JSW Vijayanagar’

Session: Tundish Optimization (Continuous Casting)

Authors: Ravishekar Konangi, JSW Steel Ltd.; Abhijit Sarkar, JSW Steel Ltd.; Suyay Patil, JSW Steel Ltd.;
Rajish Sadanandan, Vesuvius India Ltd.; Rajesh Mukhekar, Vesuvius India; Johan Richaud, Vesuvius

Abstract: In order to achieve long tundish sequences to reduce refractory cost, to improve caster yield, steel plant casting managers must schedule casting of different steel grades after another. But this transition process after a ladle change results in hybrid slabs that will be downgraded or sometimes scrapped, depending on the severity of the chemistry change. Thus it is important to determine the the intermix length to reduce these downgrades. JSW Vijayanagar and Vesuvius have reconsidered the influence of the ladle shroud design and submergence practice, the Turbostop™ impact pad geometry, the tundish profile design, along with optimizing casting processes to reduce the intermix length. In addition, grade transition predicting tools, based on both physical modeling and numerical simulations, have been evaluated and implemented by JSW Vijayanagar.
