Abstract
One way to limit excursions above the standard oxygen and moisture concentrations is to organize gas exchange in the float bath this ensures that the oxygen and moisture are continually removed to admissible concentrations Such gas exchange can be organized by continually feeding into the bath a definite amount of a protective nitrogen – hydrogen mixture ie a definite number of gas exchanges must be performed A method of determining the number of gas exchanges in a float bath taking account of the gastightness of the bath and the amount and quality of the protective mixture fed into it is examined Techniques that give the required number of gas exchanges are proposed
