What are the manufacturing processes for aluminosilicate ceramic insulation wool?

What are the manufacturing processes for aluminosilicate ceramic insulation wool?

According to their manufacturing processes, they are classified as spun-bonded cotton and spun‑fiber cotton. These materials are produced by calcining coal gangue, coke‑derived alumina, and other raw materials, followed by high‑temperature melting, and then either spun into fibers or blown into fibers. Subsequently, specialized equipment is used to consolidate the loose fibers into a cotton web of a specified thickness.

Properties and Application Scope of Aluminosilicate Ceramic Fiber Boards

Properties and Application Scope of Aluminosilicate Ceramic Fiber Boards

Through crushing and blending, spun-bonded cotton is better suited than spun‑bonded fiber as a raw material for ceramic fiber boards. Even after heating, ceramic fiber boards retain excellent mechanical strength; compared with fiber blankets and felts, they are more rigid and offer a certain degree of structural support.

Working principle, process flow, and advantages of a roasting furnace

Working principle, process flow, and advantages of a roasting furnace

The roasting furnace body is a steel shell lined with refractory, acid‑resistant bricks. Three burners are arranged tangentially on the shell to provide reheating and to dry the pre‑concentrated acid droplets discharged from the nozzles. In the furnace’s thermal zone (500–800°C), FeCl₂ decomposes according to the following equation: 2FeCl₂ + 2H₂O + 1/2O₂ = Fe₂O₃ + 4HCl.
