Production Line

First, raw materials like basalt and dolomite are selected (with strict checks on indicators such as basalt’s silicon dioxide content) and proportioned, and additives like binders or water repellents are added as needed.

The prepared raw materials are then melted in a high-temperature furnace at 1400℃-1600℃ into uniform liquid, with impurities and bubbles removed to ensure purity.

Next, the molten liquid is turned into rock wool fibers via high-speed centrifugal equipment (stretched thinner by high-speed airflow), which then settle into a fiber felt on a mesh belt under negative pressure.

After spraying a binder (e.g., phenolic resin) on the felt, it is cured in a furnace at 180℃-250℃ for 10-30 minutes to form solid rock wool boards.

Finally, the cured boards are cut to specified sizes, inspected for appearance and physical properties (e.g., density, thermal conductivity), and qualified ones are packaged and stored.
