Zirconium containing ceramic fiber blanket is a high-end high-temperature insulation material, with a long-term temperature resistance of 1260-1350 ℃ and a short-term temperature resistance of up to 1500 ℃, which is more than 300 ℃ higher than that of ordinary ceramic fiber blanket. In high-temperature scenarios in steel plants, it has core advantages such as low thermal conductivity, low heat capacity, thermal shock resistance, slag corrosion resistance, and chemical stability, which can effectively save energy, stabilize temperature, and extend equipment life. Functional effect: Low thermal conductivity and excellent insulation effect; Low high-temperature shrinkage rate and stable structure; Resistant to rapid cold and heat, not prone to powdering and cracking; Resistant to reducing atmosphere and alkaline corrosion in steel mills, with a long service life; The material is flexible, has high tensile strength, and is easy to construct. Application areas of steel plants:
Heating furnace, soaking furnace, annealing furnace: furnace lining and backing, hot surface insulation, temperature control and energy saving
Ladle, ladle, intermediate ladle: Cover insulation to reduce temperature drop
Hot rolling and heat treatment furnaces: expansion joint sealing, insulation baffle
High temperature flue and hot air duct: thermal insulation to reduce heat loss
Annealing furnace, walking furnace: furnace body insulation, fire blocking and temperature insulation
