What is the manufacturing process of ceramic fiber blanket?

The manufacturing process of ceramic fiber blanket involves several key steps. Initially, raw materials such as alumina-silica or calcium-magnesia are mixed and melted at high temperatures in an electric furnace. The molten material is then extruded through a spinneret to form fine fibers. These fibers are collected on a conveyor belt and simultaneously coated with a binder to provide strength. The fiber mat is then passed through an oven to cure the binder. Finally, the cured fiber mat is cut, rolled, or packaged as a ceramic fiber blanket. This material is known for its high-temperature insulation properties and is widely used in various industrial applications.
