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, i.e., 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 gas-tightness 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.
