Resumo

"The CNC Shrouded* is a tundish flow control system that allows the cast of long products in both open or shrouded stream from tundish to the mold. This allows steel of higher quality to be cast by protecting the stream from the re-oxidation from atmosphere as well as the usage of flux powder as lubricant, which also improves quality in terms of surface and thermal exchange with the mold. The trials were conducted to validate the proposition and evaluate the differences in terms of quality, considering surface of the billet, and as a second step, chemical analysis of samples. The preliminary results have proven the system improves significantly the quality, by having a much better surface quality as well as no re-oxidation, while being of simple usage operationally and of lower cost compared to other systems where there is flow control, such as tundish slide gate or stopper and submerged entry nozzle. *trademarks of the Vesuvius plc group of companies, unregistered or registered in certain countries"
