Method for manufacturing bent and tempered glass sheets and apparatus for manufacturing the same |
摘要 |
<p>In a quenching apparatus for quenching a glass sheet that has been heated and bent in a heating furnace, a cooling gas blows onto the glass sheet to provide a distribution of a temperature and/or a distribution of a static pressure in at least one section in the quenching apparatus. The distribution of a temperature provides different temperatures between the both surfaces of the glass sheet, while the distribution of a static pressure is nonuniform in a part of at least one surface of the glass sheet. The distributions can modify a shape of the glass sheet given in the heating furnace so that a degree of freedom in shape for manufacturing a bent and tempered glass sheet by utilizing its self-weight can be improved. <IMAGE></p> |
