Abstract
The research results were used to create the original purging block for industrial tests on slab caster PJSC “Alchevsky Iron and Steel Works”. Design feature of the purge block is its geometrical form as a ring covering the tundish nozzle. This injection argon through calibrated holes made in special refractory tubes. As a result of tests, that maximum refining effect is achieved at a flow rate of 10 – 12 l/min.
