一腐蚀原因及模拟试验硅酸铝纤维是一种新型隔热保温材料,它具有耐高温、热导率低、热容量小、质量轻、抗热震性能好、化学性能稳定等特点。它用于手工业电炉内壁衬里,使电炉具有隔热保温性能好、升温速度快、省时节能等优点,对提高生产率、降低成本及改善劳动条件等方面有显著的经济效益,而且温度越高节能效果越明显。按使用温度,硅酸铝纤维可分为用于1000℃以下的普通硅酸铝纤维和用于1000℃～1300℃的高铝纤维。其化学成分分别见表1和表2。
A Corrosion Reason and Simulation Test Aluminum silicate fiber is a new type of thermal insulation material. It has the characteristics of high temperature resistance, low thermal conductivity, small heat capacity, light weight, good thermal shock resistance and chemical stability. It is used in the lining of handicraft inner wall of electric furnace, which makes the electric furnace have the advantages of good heat insulation and heat preservation, fast heating speed, saving time and energy, etc. It has obvious economic benefits in raising productivity, reducing cost and improving working conditions, etc., The effect is more obvious. According to the use of temperature, aluminum silicate fibers can be divided for the ordinary aluminum silicate fiber for 1000 ℃ below and 1000 ℃ ~ 1300 ℃ for high aluminum fiber. The chemical composition of Table 1 and Table 2 respectively.
