Modular furnace lining is also called component furnace lining, which is actually composed of prefabricated modules (assemblies). The main advantages are rapid installation and convenient maintenance. The standard module is generally 300 and 300 mm, and the thickness depends on the thermal calculation requirements, generally between 100~300 nm. There are many kinds of prefabricated components (modules) developed in recent years, and their structural forms include stacked, U-shaped folded, stacked, fish scale, accordion folded and vacuum formed shell.

In fact, the stacked components are small blocks of stacked furnace lining` It has been made of fiber blanket or felt block, and it is fixed on the porous metal mesh support plate by the combination of fire-resistant mastic bonding and metal clamp fastening_ L。 During installation, clamp, welding, screw connection and other methods shall be used to fix it on the furnace shell}:. For the high overflow furnace, in order to meet the energy-saving requirements of the furnace economically, the components can be made into composite type.

The U-shaped folding component is made of fiber blanket and is fixed on the metal mesh plate by cementation and mechanical means. The manufacturing method is simple.

The fiber blanket in the laminated component is perpendicular to the heat flow direction, which has the advantage of laying furnace lining layer by layer. Accordion components are also called z-shaped groups. Like fish scale components, it is designed to compensate for thermal shrinkage.

The vacuum forming component is made by filling the vacuum forming shell with scattered fibers. The housing is equipped with special chute, pin buckle and other devices to facilitate installation.
