    • A method for bending radiation shielding glass which has a heavy metal oxide content of at least 50% by weight is provided, wherein first a mold is provided, a glass plate comprising a radiation shielding glass is then provided, the mold is preheated to a temperature of 300 to 400° C., the glass plate is placed on the mold, the glass plate and the mold are heated in a furnace to a temperature of 370 to 430° C., then heated together to a temperature of 400° C. to 500° C., preferably to 440 to 500° C., the total heating time being at least 30 minutes, preferably at least 60 minutes, the glass plate is then molded and finally the molded glass is cooled by means of a cooling program over a period of at least 60 minutes. For thermal prestressing, the glass body is supported at least at its outer periphery at a number of support points, introduced into a preheated furnace, heated to 400 to 500° C. and then removed, and cold air is blown onto both sides from a multiplicity of nozzles, preferably until cooling to about 100° C. has taken place.
    • 提供了重金属氧化物含量为至少50重量%的辐射屏蔽玻璃的弯曲方法,其中首先提供模具,然后提供包括辐射屏蔽玻璃的玻璃板,将模具预热至温度 在300〜400℃下,将玻璃板放置在模具上,将玻璃板和模具在炉中加热至370〜430℃的温度,然后一起加热至400℃ 至500℃,优选440至500℃,总加热时间为至少30分钟,优选至少60分钟,然后模制玻璃板,最后通过冷却程序冷却模制玻璃 至少60分钟的时间。 对于热预应力,玻璃体至少在其外围的多个支撑点处被支撑,被引入到预热的炉中,加热到400-500℃,然后除去,并且冷空气从 喷嘴的多样性,优选直到冷却至约100℃。
