9th ECCC European Continuous Casting Conference – ECCC 2017

Technical solutions and design optimization for better quality, increased productivity and yield have been continuously introduced and implemented in Tata Steel thin slab plant located in Jamshedpur – India to further improve competitive edge in the current steel market. Extensive advanced computer simulations and physical simulations have been conducted to determine the different parameters characterizing both tundish and mold flow. Reduction of dead and cold steel volume, improved inclusion floatation and turbulence reduction in the impact region have been obtained after optimizing the internal tundish geometry. With the new tundish internal geometry, the tundish skull weight has been reduced by 20% with out any quality issues. Addition of tundish gas bubbling device aka TGD is introduced, installed & under evaluation to achieve the reduction of process issues. The new Sub-Entry Nozzle is used to produce stable meniscus flow and optimal mold temperature distribution for flow rate at around 11% higher Thpt than current design & it is planned to increase thpt by further 15% by further study..
