【摘要】 本文介绍了“舟型浅槽六排孔短漏板”坩埚拉丝试验的主要情况及经济效益分析.木浅槽漏板不同于“浅槽平漏板”,它是集节铂、小张力于一身,并采用了骨架增强技术,漏板重量在450克左右.拉丝作业稳定,原丝质量好,漏板寿命4～6个月,很有推广价值.更多还原

【Abstract】 This paper introduces the main conditions and economic results of fiber drawing tests of boat - shaped shallow and short bushing with 6 rows of nozzles. Dissimilar to the "shallow and flat bushing plate", it has the advantages of Pt saving and less tension,being frame reinforced,and at the weight of around 450g. Fiber drawing tests showed that drawing operation was stable and glass strand good quality, and the bushing plate lasted 4-6 months.更多还原
