Input materials supplier Wilec holds exclusive distribution rights of MicaSIL, an electrothermal insulation sheet that is flexible and thermally resistant and can be used as a slip plane insulation between the crucible and induction coil in induction furnaces.

Wilec is the exclusive reseller of MicaSIL in Africa.

MicaSIL protects the furnace lining from the contraction and expansion forces in melting operations, serves as a heat barrier and acts as a slip plane, facilitating easy removal of the crucible.

MicaSIL offers several benefits in industrial applications, including significantly reducing energy costs by minimising heat loss through the ramming mass, while also providing a slip plane that allows unrestricted expansion and contraction of the lining during thermal cycles.

In the case of molten metal leak-through, MicaSIL acts temporarily as a protective barrier. It also prevents condensation of moisture and harmful gases on coils, thereby preventing premature coil failure.

Additionally, the slip plane properties of MicaSIL facilitate the easy removal of spent crucibles, thereby extending the lifespan between patching and re-linings.

Importantly, MicaSIL is non-injurious to health, ensuring safety in workplace environments.

Company Background
