In the modern steel industry, in order to improve the thermal insulation performance of the ladle, increase the service life of the lining body, and reduce the consumption of refractory materials, a new type of ladle has emerged. The so-called new ladle is to widely use calcium silicate board and aluminum silicate fiber blanket in ladle.
What is aluminum silicate fiber blanket?
Aluminum silicate fiber blanket is a kind of refractory insulation material. Aluminum silicate fiber blanket is mainly divided into blown aluminum silicate fiber blanket and spun aluminum silicate fiber blanket. Spun aluminum silicate fiber blanket has longer fiber length and has smaller thermal conductivity. So it is better in thermal insulation than blown aluminum silicate fiber blanket. Most pipeline insulation use spun ceramic fiber blankets.
Characteristics of aluminum silicate fiber blanket
1. High temperature resistance, low bulk density and small thermal conductivity.
2. Good corrosion resistance, oxidation resistance, thermal shock resistance, etc.
3. The fiber has good elasticity and small shrinkage under high temperature conditions.
4. Good sound absorption.
5. Convenient for secondary processing and installation.
Based on aluminum silicate fiber blanket’s physical and chemical properties, it is widely used in furnace linings, boilers, gas turbines and nuclear power insulation welding to eliminate stress, heat insulation, fire prevention, sound absorption, high temperature filter, kiln door sealing, etc.
