Abstract

"MéTODO PARA PROCESSAMENTO DE TUBO DE VIDRO, APARELHO E TUBO DE VIDRO". Em um método para processamento de vidro de acordo com a invenção, no caso de executar a deposição com vapor químico ou contração de diâmetro de um tubo de vidro de substrato G movendo relativamente um forno de aquecimento 20 compreendendo um elemento de aquecimento 21 para envolver de modo anular a circunferência do tubo de vidro de substrato em uma direção longitudinal do tubo de vidro de substrato G com relação ao tubo de vidro de substrato G no qual o diâmetro externo é 30 mm ou mais e a espessura da parede é 3 mm ou menos e é menor do que 15 mm e a forma oval do diâmetro externo é 1,0% ou menos usando um aparelho para processamento de vidro 1, a temperatura de pelo menos um do elemento de aquecimento 21 e do tubo de vidro de substrato G é medida e a quantidade da geração de calor do elemento de aquecimento 21 é ajustada com base na temperatura medida.
