ガラス成形時におけるガラスと金型内表面との間の熱伝達

抄録

The heat transfer mechanism is fundamental to container forming because of the dependence of glass viscosity and other properties on temperature. The objective of this paper is also to learn a knowledge of heat transfer during forming operation.
A method for determining the coefficient of heat transfer between glass and mould inner surface during glass container forming operation was presented.
The values of the coefficient of heat transfer h obtained were as follows:
In blow process h=1500-2300kcal/m²⋅h⋅°C and in press process h=4000-7000kcal/m²⋅h⋅°C on some machines, i.e., IS, New-10 and LA etc., in the temperature ranging gob temperature=1065-1100°C, parison temperature=620-730°C and temperature of mould inner surface=370-495°C.
