Components and Uses of Fireproof Insulation Material

And according to the chemical component, there is alumina silicate insulation fiber or ceramic fibre insulation, which is made of hard clay clinker, being produced in the process of blowing after the electric arc furnace melting. It is called ceramic fiber due to one of its main composition, alumina, which is the main ingredient of porcelain. Besides the alumina, it is also added zirconia or chrome oxide, etc. to improve its using performance. Fireproofing materials such as  alumina silicate fiber board, alumina silicate fiber felt, alumina silicate rope and alumina silicate fiber blanket, etc. are usually used as the sealing and insulation materials in various industries. In addition, and they are used usually together with the refractory bricks, which affect the performance of the insulation materials. So refractory users should choose the correct materials to save energy and reduce cost.
