硅酸钒纤维,在箱式电炉,井式电炉上推广,使用时间还不长,根据使用单位的情况来看,硅酸铝纤维能忍受900℃的温度。经过几个月的使用无损坏现象,节电效果达30%左右。为此我们根据它的特性,设想是否可以存我厂炼钢车间,铸钢工段燃煤台车式回火炉j-进行运用。我厂叫火炉工作温度最高达900℃,主要是恫来烘烤铸钢什砂模进行干燥和铸钢件回火处理。烘烤砂模温度最高在500℃以内,钢件回火在900℃以内,硅酸铝纤维的耐火点是能够达到使用要求的,纤维材料本身热容量小,气孔率大。材料本身是白色的,热幅射、隔热效果好,使用后并可以增加炉子的密封性。有升温快的特点,根据这些特性,
Vanadium silicate fiber, in a box-type electric furnace, pit furnace promotion, the use of time is not long, according to the use of units of view, aluminum silicate fibers can tolerate 900 ℃ temperature. After several months of use without damage, the power saving effect of about 30%. To this end we based on its characteristics, whether it can be stored in our factory steel plant, the steel section of coal-fired tempering furnace j- for use. I plant called the stove operating temperature up to 900 ℃, mainly 恫 to bake cast steel sand mold for drying and tempering steel castings. The highest temperature of baking sand mold is less than 500 ℃ and the tempering of steel is less than 900 ℃. The refractory point of aluminum silicate fiber can meet the requirements of use. The fiber material itself has small heat capacity and large porosity. The material itself is white, thermal radiation, thermal insulation effect, after use and can increase the furnace sealing. Have the characteristics of warming fast, according to these characteristics,
