Abstract

To prevent the formation of continuous cracks (5,5a) from the outside to the throughflow opening (1) in a refractory valve plate (A), stress-relieving cavities (4) are provided around the said opening. These cavities are provided, if required, with a sealing material preventing outside air from being drawn in as far as the throughflow opening (1) through cracks (5,5a) which have arisen.
