In the modern steel industry, in order to improve the thermal insulation performance of the ladle, at the same time increase the service life of the ladle lining, and reduce the consumption of refractory materials, a new type of ladle is produced. The so-called new ladle is produced with calcium silicate board and aluminum silicate refractory fiber blanket.
What is aluminum silicate refractory fiber blanket?
Aluminum silicate refractory fiber blanket is a kind of refractory insulation material. Aluminum silicate refractory fiber blanket is divided into blown aluminum silicate fiber blanket and spun aluminum silicate fiber blanket. In most pipes insulation project, It is the spun aluminum silicate fiber blanket that is used.
Characteristics of aluminum silicate refractory fiber blanket
1. High temperature resistance, low density and small thermal conductivity.
2. Good corrosion resistance, good oxidation resistance, good thermal shock resistance, etc.
3. The fiber has good elasticity and small shrinkage under high temperature conditions.
4. Good sound absorption.
5. Easy for secondary processing and installation.
Aluminum silicate refractory fiber blanket is widely used in furnace linings, boilers, gas turbines and nuclear power insulation welding to eliminate stress, heat insulation, sound absorption, high temperature filter media and kiln door sealing.
