Tundish to Mold Refractories
To improve competitive edge in the steel market, Tata LD3 and Vesuvius are constantly working on improving quality, productivity and yield in thin slab CSP ® caster located at in Jamshedpur, India. Reduction of tundish refractory wear and skull weight at the end of the sequence are directly impacting caster yield and productivity
Numerical and physical simulations have been conducted to determine the different measurable parameters for tundish and mold flow improvements. Increased minimum residence time, improved inclusion floatation, turbulence reduction have been obtained after optimizing the internal tundish geometry. The optimized tundish internal geometry has been implemented with success allowing tundish weight reduction by approximately 4 tons without any tundish slag entrainment.
The current Sub-Entry Nozzle has been modified to producing stable meniscus flow and optimal mold temperature distribution to achieve higher average casting speeds, particularly in wide slab formats.
