近几年来,国内已出现了全纤维炉。由于材料本身的特性,大大地降低能耗引起了人们的重视。在普通硅酸铝纤维、高纯硅酸铝纤维、高铝纤维和高纯含铬硅酸铝纤维相继出现后,八十年代初期,国外又试制成功晶体纤维(多晶氧化铝、多晶莫来石纤维等)。多晶莫来石纤维(简称:PMF)的微视组织是由微晶体构成的一种耐高温纤维,其使用温度高达1500℃,具有柔弹性、蓄热量低、导热系数小,并对突变的温差有良好的抗阻性,可应用在各种炉窑上做内衬,尤其是在间歇式炉上可明显起降低能耗,并能使炉体结构轻型化,简单化。浙江德清晶体纤维厂于今年初已试制成功晶体纤维,并通过了技术鉴定。该厂的多
In recent years, there have been all-fiber furnace in China. Due to the characteristics of the material itself, greatly reducing energy consumption has aroused people’s attention. After ordinary aluminum silicate fibers, high-purity aluminum silicate fibers, high-alumina fibers and high-purity chromium-containing aluminum silicate fibers appeared one after another, in the early 1980s, foreign countries successfully produced crystalline fibers (polycrystalline alumina, Stone fiber, etc.). The microporous structure of polycrystalline mullite fiber (abbreviation: PMF) is a kind of high temperature resistant fiber composed of microcrystal. Its working temperature is up to 1500 ℃, it has flexibility, low heat storage capacity, small thermal conductivity, Of the temperature difference has good resistance, can be used in a variety of furnace lining, especially in the intermittent furnace can significantly reduce energy consumption, and can make the furnace structure, lightweight and simple. Zhejiang Deqing Crystal Fiber Factory earlier this year has successfully trial crystalline fiber, and passed the technical appraisal. The plant more
