- Heating/drying of steel-teeming ladles
During drying, the flame temperature changes from 100˚С to 2000˚С (L> 15... L≈1), this allows the use of progressive modern cyclic drying schedules.
This system was developed by SNT for drying new linings in order to achieve the highest expected lining life or to heat used ladles.
During drying, additional air is supplied to the burner, bringing › L› to 10 and reducing the flame temperature to values from 100˚С.
Thanks to this method, a warm vortex air flow is created in the ladle, which avoids rapid and strong heating inside the ladle during lining drying and achieves an even temperature distribution throughout the ladle column (+ _ 10˚C). Strong spot heating at the bottom of the ladle is also eliminated.
Due to SNT, the following advantages are achieved:
