Abstract

PURPOSE: To reduce the thermal fatigue of a nozzle corner part, by means of connecting the space between a coolant injecting nozzle and a thermal sleeve, and an inner part of the sleeve, and of allowing the warm water to be absorbed into the sleeve by lowering the pressure of the coolant at this connecting part.
